Update: Please post new comments in the latest HPMOR discussion thread, now in the discussion section, since this thread and its first few successors have grown unwieldy (direct links: two, three, four, five, six, seven).

As many of you already know, Eliezer Yudkowsky is writing a Harry Potter fanfic, Harry Potter and the Methods of Rationality, starring a rationalist Harry Potter with ambitions to transform the world by bringing the rationalist/scientific method to magic.  But of course a more powerful Potter requires a more challenging wizarding world, and ... well, you can see for yourself how that plays out.

This thread is for discussion of anything related to the story, including insights, confusions, questions, speculation, jokes, discussion of rationality issues raised in the story, attempts at fanfic spinoffs, comments about related fanfictions, and meta-discussion about the fact that Eliezer Yudkowsky is writing Harry Potter fan-fiction (presumably as a means of raising the sanity waterline).

I'm making this a top-level post to create a centralized location for that discussion, since I'm guessing people have things to say (I know I do) and there isn't a great place to put them.  fanfiction.net has a different set of users (plus no threading or karma), the main discussion here has been in an old open thread which has petered out and is already near the unwieldy size that would call for a top-level post, and we've had discussions come up in a few other places.  So let's have that discussion here. 

Comments here will obviously be full of spoilers, and I don't think it makes sense to rot13 the whole thread, so consider this a spoiler warning:  this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series.  Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.

A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted.  This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.

Slightly edited the original post to avoid giving away what my readers have finally convinced me is, in fact, an undesirable spoiler. I also hope you didn't mind my removing the mention of FAI, because I feel fairly strongly about not mixing that into the fic. "A fanatic is someone who can't change their mind and won't change the subject"; if we can't shut up about FAI while talking about Harry Potter, we may have a problem.

ETA: Spoilers for chapters in the early 100s.

Very true, and I don't agree with some comments that I've seen lately (and probably they've been around all along) complaining about all of the shout outs.

But we may have more of a shout-out here: there's a strong implication that the Mirror of Noitilov was created by Atlanteans attempting to create an honest-to-goodness FAI to avert an existential threat. Since Atlantis may have created magic entirely, and since there is already a lot of speculation among the fans that the existence of magic implies that MOR is a simulation run by an AI, this would put FAI and the existential threat of UFAI into the background of the world at a deep level.

Of course, only you know if this implication and speculation are correct. And either way, I'm not complaining!

The writing style seems to go for similar overkill as in XKCDSucks-blog, that is, every tiny detail is taken out of context and twisted until it is made look bad. Plain honest deconstruction and critique would be fun, as there are many things I think are quite awful with MoR, mostly I dislike the unnatural feeling every single human relationship has and how many speeches about science seem to be a bit unrelated and be there just for lecturing the reader without justification from story, and how Harry seems to be Mary Sue so very much it's actually annoying. MoRSucks however seems to go drowning real bad points into a sea of motivated cognition. It seems bad. Weird and untruthful, strawman-like, as far as I can tell, portrayal of MoR fans doesn't help.

That's a really good analysis of the problems with MORSucks. Unfortunately, people who only slightly dislike a work, or acknowledge that has some flaws but enjoy it anyway, seldom form blogs devoted to deconstructing it. In general, you have to choose between overwhelming praise and overwhelming hate.

So maybe it's just me but my reaction to the fanfic was something like "Eliezer is writing rationalist Harry Potter fanfiction. That's pretty awesome. And educational!" I check it every so often to see if there is a new chapter and I've shared it with a couple people. That's pretty far from:

Basically, Mr. Yudkowsky's ubiquitous yes-men like to claim (quietly encouraged by the man himself) that this fic somehow transcends its medium to become some sort of higher work

It seemed like most people had similar reactions to mine, but maybe Less Wrongers have been making a bigger deal out of it elsewhere? We didn't even have this thread until a couple of chapters ago.

Similarly:

apparently Mr. Yudkowsy had a sizable online following prior to writing this tour de force, and I guess some of it must have overlapped with the Potter fandom, because this fic quickly skyrocketed in popularity and number of reviews

My sense was that we had almost nothing to do with the popularity. It didn't get linked to from LW until like chapter 12 or so, if I remember correctly. I know a couple people here made image macros but Eliezer's following isn't nearly large enough to generate this kind of popularity by itself, right?

As for the rest of it: it reads like my mother critiquing MTV, the author doesn't understand where the author is coming from or who he is writing for and as a result totally misses his target. For example, the fact that Harry has three last names clearly isn't Eliezer making sloppy feminist statement. If anything, he's laughing at himself and the subculture he's a part of. I laughed out loud when I read it because obviously rationalist-Harry would have a compounded name. It's exactly the right amount of PC-vanity for the family of an Oxford professor with a kid too smart for his own good.

I was referred to initially to it by two people who are not LW readers.

The individual writing the blog may be suffering from a bit belief overkill (one of my favorite cognitive biases. Someone should do a top-level post about it at some point. Many different cognitive biases can be thought of in a belief overkill framework).

Is belief overkill different from confirmation bias (which is what comes up when I google)?

comment by JoshuaZ · 2010-06-08T00:47:47.431Z · score: 4 (4 votes) · LW · GW

They're related. Some argue that confirmation bias is an example of belief overkill. Belief overkill is basically the tendency for people to accept all arguments that support their opinion even if it is only in a peripheral fashion. Thus, for example, people who think that using fetal stem cells for medical purposes are moral are much more likely to think that stem cells will be really medically helpful than people who think that such use is bad. Essentially, people compile arguments for why X is Good/Bad rather than dividing questions properly. There are some posts that touch on this issue (such as those discussing why politics is a mind-killer) but I'm not aware of any post discussing this issue in detail (although given how extensive the archives are I estimate a high probability that I've simply missed the relevant ones).

Motivated cognition would also be a special case of belief overkill-- it's being too ready to develop and accept arguments what you want to believe. Belief overkill is the same process applied to arguments from both yourself and other people.

Well, so far I'm not impressed by the criticism of chapter 1. I've been meaning at some point to write something about where I think Eliezer's gone wrong, but now I think it might be more interesting to wait and see if this individual produces anything interesting. Given that the individual is a fan of the xkcdsucks blog, I'm a bit skeptical that I'm going to see much of interest. Judging from the chapter 1 review it looks like the writer is having some of the same problems as those people (One major one is assuming that setups or characters are necessarily ideals just because they are sympathetic or protagonists)

That site does seem like a bad case of motivated cognition, but I'm going to read a little more of it to see whether the author comes up with something interesting.

One thing that's mildly interesting is a criticism of MoR as being humanities-deficient. It would be interesting to see someone (possibly not Harry Potter-- he's too young) coming into the wizarding world with a strong humanities background.

I read a fanfic a while ago involving a journey to afterlife (set after 5 and written before book 6 had come out) involving a journey to the underworld to try to get Sirius back. Hermione had apparently read enough mythology and other works to become genre savvy about what to expect. The end involved dealing with a creature that had been promised a pound of flesh from Harry and she then used the standard trick from The Merchant of Venice to deal with it. When the others are impressed she explicitly stated where it was from and gave a brief rant about how wizards should read more Muggle writing.

Yes, in the story it went slightly differently than it occurs in Merchant of Venice. Hermione waited until after the flesh had been torn from Harry to tell the underworld spirit that it had violated the deal and then negotiated back the restoration of everything as an appropriate penalty for it violating the deal.

That was a hard swat at "The Ones Who Walk Away from Omelas".

As for why Harry has such an exaggerated sense of responsibility, it might be that growing up on science fiction thing. A lot of science fiction is set up so that the hero can have a huge effect in a satisfying way. Perhaps Harry should have balanced it with reading history. On the other hand, he's living in fiction, so maybe he's right for his situation.

Lois McMaster Bujold has described sf as fantasy of political agency [1], and I think she's on to something.

I assume that shutting down Azkaban has a political solution rather than a magical or violent solution. This will be interesting to watch.

Why would Snape ask Harry for his take on Snape's past? One of the underlying premises of the story is that the smarter characters (possibly with the exception of Hermione) always have a deeper plan. Did Snape actually expect to get good advice? To be told that all his choices were correct? To have a reason to be angry at Harry? None of these make huge amounts of sense (to me, at least-- I have trouble keeping track of all the scheming), even though the scene was very emotionally effective.

Quite the opposite. I was tempted to respond to the review but had been left without an appropriate forum.

I had to go back and figure out where you thought the Omelas reference was. Harry's observation just seemed obvious to me.

As for why Harry has such an exaggerated sense of responsibility

Personally, I don't even see anything to explain. Billions of people are suffering, and at least billions are going to die, and most people are observably doing nothing about it. Harry seems to have good reason to think he's the only one that can do anything, if only because he's the only one (or one of just a few) who noticed and/or cares.

Harry is right to take responsibility for the universe's troubles, as we all should.

I assume that shutting down Azkaban has a political solution rather than a magical or violent solution.

I think Harry was just using Azkaban as an example, and there will turn out to be more of a general solution to the world's problems unless Harry finds himself dealing directly with Azkaban.

Harry's problem seems to be not that he has decided to do something about it but that he takes pride in feeling guilt over the suffering of everyone (even obscenely evil people). It is on thing to prefer to take over the universe and allow the evil people to live freely in a way that can't hurt others, but it is quite another to be all emo about it. That achieves nothing except allow harry to feel self righteous.

I also wonder why Snape got offended. Harry's answers were extremely supportive of Snape's situation back then: which makes me think Snape wasn't really offended, just pretending to be. Maybe the whole point was just for Snape to tell Harry the unpleasant truth about his parents in an emotionally powerful way, as a way of getting back at Harry because of his parents.

It is possible to respond in a less direct way. Competent social skills would suggest putting very little actual content into his answer. I am less cunning than Harry and not known to be particularly conservative in my expression of potentially provocative positions but even so I do not think I would have all that much trouble responding with tact. Snape would still make a hostile reply but he does that to answers to potions problems anyway. He probably wouldn't be tempted to kill me.

What is most interesting to me is how Snape handles being offended. Snape has been portrayed in this FanFic as being extremely shrewd and self controlled. Harry even made observations along those lines himself, upgrading his respect for Snape considerably.

Snape (quite rightly) downgraded his trust in Harry's cunning. I wonder if Harry downgrades his respect similarly. If Severus had the cunning of even the 11 year old Malfoy he would not 'never talk to Harry again". Any benefit that he could hope to extract from Harry is still there and Severus is enough of a political agent to work past some offence when given a few months to cool down.

Here's my take on what actually happened in the dojo incident described in chp 19.

Voldemort went there in disguise to learn the valuable martial art. He reacted badly to losing so they put him through the ordeal he described. He went along with it because he wanted to learn the martial art. The ordeal did teach him valuable lessons about losing, and he vowed to learn to control his temper and master tactics of ingratiation and supplication to better manipulate others. But he felt angry and humiliated by it (as he expected Harry to be), and also vowed to return and fulfill his revenge fantasies. So after he mastered the martial art and left the dojo, he came back openly as the Dark Lord and killed them to live out his revenge fantasies and to prevent others from learning the skills (keep science secret). He spared one student who had befriended him (and who probably stood up for him during the ordeal, like Draco to Harry), and he had that student spread the version of the tale that he wanted told (to maximize fear while hiding some of his true powers, and to deflect attention away from the value of that martial art).

That's certainly possible, but we know Q/V does have elite martial arts skills, which he had to have learned somewhere, and studying at the world's best dojo, followed by destroying it to make sure no one else ever got training as good, seems like an entirely plausible thing for a Dark Lord to do.

My understanding was that the story was true as stated: Voldemort showed up, destroyed the place, then calmed down and realized Quirrell now had the only remaining copy of the information he was looking for, so he set up some contingency to eventually put himself in Quirrell's body with the martial-arts skills intact.

Is there any hint in MoR that Quirrel was already a total badass before Voldemort's body-snatching job, as this interpretation would require ("I was a prodigy of Battle Magic even then [at the times of the dojo]")?

I think 'last surviving student of the greatest martial-arts teacher' counts as a hint, yeah.

Why would Quirrel's battle-magic skill, or lack thereof, be relevant in Voldemort's choice of host? Magic is at least partly a function of the mind, and judging by the descriptions of zombie-like behavior when off-duty, the body-snatching didn't do Quirrel's mind any favors. Rather, the point would be to combine Voldemort's lifetime of rationality and Battle Magic practice with Quirrel's sixth-dan hand-to-hand combat skill, resulting in a single individual with two lifetimes' worth of powers, without the expense and possible side-effects traditionally associated with magical life extension.

Speaking of which, isn't there a prefabricated, ready-to-use Alchemist's Stone somewhere on campus?

Agreed, except there's no particular reason for a Dark Lord to actually leave a survivor when he can just have his minions disseminate it. (Or do so himself as Quirrell; we have no knowledge of how long this story has been around.)

ETA: Actually I should say my first thought was that Voldemort destroyed the dojo not out of anger, but simply to make sure that no rival wizard ever got the awesome martial arts training that he did. This seems strongly implied when he says: "You are wondering where this marvelous dojo is, and whether you can study there. You cannot."

It seems like the spells in the HP universe are complicated and abstract enough that they must have been designed (programmed?) by wizards long ago, who added them to the laws of the universe and left them there.

Now, if I were designing a spell like the Killing Curse, I would include a little easter egg/safety mechanism: after a thousand castings, it backfires. Choose a number large enough that only a major dark wizard like Voldemort will encounter it, so it doesn't hit some minor villain and spoil the surprise. (Alternatively, rather than counting kills, count evilness, with killing a baby counting for more evilness points than an adult. That would explain why it backfired on Harry Potter, rather than some other victim.)

This is the most sensible explanation I can come up with. Or it could be that it backfired because the third through fifteenth places of the decimal expansion of the local humidity were a prime number, or something similarly arbitrary. But I would be disappointed if it was something like that. (I would also be disappointed if his parents came up with a spell that reflected it, because everyone seems convinced that no such spell is possible.)

Well, the word 'wing' does date back to the 12th century, a little earlier than halfway between us and Merlin, and a time in which learned people did know Latin but were also starting to mangle it up pretty badly (not quite that badly IRL, but if we assume wizards were always a bit more eccentric than Muggles...).

Unfortunately, that particular fan-wank completely breaks down when you consider that the pronunciation (let alone spelling) of 'wing' was nowhere near the same back then. Although you could save it by suggesting that, just as spoken language evolves really, really slowly, so did the spell-marks imprinted on reality as the spell got cast a million times over a thousand years, a wee little bit differently every time.

I haven't thought about this idea completely, but a karma system can actually be maintained in a magical society. I mean actual karma, the way Hindus and Buddhists think about. What goes around, comes around. Violate it badly enough and the universe will make an exception just to get you out of the way. As another commentor put it, somebody would have tried to protect another while they were being avara-kedavra'ed, earlier than lily protecting Harry. But voldemort's karma credit really ran out. So, whoopsie, there goes the body. But of course, he had his horcruxes.

But if making people realize that we have to wake up in this hostile universe is one of the goals of this fic, the above wouldn't be true in HP&MOR.

Another speculation, maybe true prophecies only come when there are serious thresholds crossed.

If you could program a slaying weapon, what is the one group of people that no-one in their right mind could possibly ever want to kill? I'd say that group would be children too young to speak. Anyone going after them is certainly an absolute psycho.

I'm reading MOR with considerable interest and enjoyment-- and recommending it-- but.....

There's a big emotional difference between HP and MOR. In the original, Harry has no friends or allies at the Dursley's. In MOR, his family life isn't great and he doesn't seem to have any friends or anyone he's expecting to miss, but he isn't under constant attack.

Part of the emotional hook in HP is that Harry is almost immediately in a circle of friends and acquires a family in the Weasleys.

In MOR, his best emotional connection is to McGonagle, but it's complicated by his intellectual dominance. None of his close friends from HP are worth being close to (or did I miss someone?). His nearest approach to a friend his own age is Draco, and that's very much complicated by Draco having been raised to be a sociopath, and by Harry's need to manage Draco.


Part of the charm of HP was that Hermione's memory, intelligence, and conscientiousness are presented as more valuable than annoying, though the annoyance for the other characters is still there. This is a rationalist feature of HP which seems to be lost in MOR-- Hermione is interested in getting things right for the sake of status.

Her delight at being in a Romance completely eclipsing the question of whether she likes Harry is depressing, but within the human range, I think.


QuirrelMort setting up the Harry's structured humiliation no doubt has plot reasons, but I can also model it as organizational hysteresis-- after Harry made such a strong power grab in re Snape, it's plausible that great efforts will be made to remind him that he's just a student.


I have a notion that it wasn't just his mother's sacrifice that saved Harry, it was also something he did, and his reflexive rage and need to win is hooked to what he did to survive when he was a baby.


is the training that Draco is getting from Lucius based in anything from the novels? The Dracos never impressed me. They just seemed to be rich and mean, and the Pure Blood campaign is weirdly abstract and idealistic compared to their temperaments. (Is there a reverse halo effect where all bad qualities accrete something which is considered to be bad? The Dracos are bullies, so of course it's reasonable to turn them into Nazis.) To my mind Slughorn is part of the real range of Slytherin possibilities.

I need to object pretty strongly to this particular phrase. Draco is not being raised to be a sociopath; he's being raised to be a high-status member of a hierarchical society. Draco and his father very much love each other, and are perfectly capable of making real emotional bonds with people that they have identified unequivocally as 'pack'. EY has actually done very well at showing Draco as what a perfectly normal child becomes in that environment.

This is an important distinction, because we need to remember that 'sociopathy' is a comparatively rare (and usually inborn) condition, while high-status machiavellian narcissism is a natural consequence of human evolutionary psychology.

I agree to an extent. He does remind me of people I've known in the rationalist movement. It's worth pointing out that him blurting out the wrong thing at the wrong time isn't just an annoying character trait, it's probably symptomatic; I'd speculate he doesn't really consider other people as fellow actors in his decision making. If there was someone who did not make efforts to bond with people around him, would you be willing to trust him with power over their happiness?

That's a non hypothetical question, I'd love to hear a rebuttal.

I just read Chapter 27. My thoughts:

"Mr. Bester" - great reference.

Harry is firmly on the 'get absolute power' path. Probably he still thinks he's being cute or knowing when he talks about becoming God. His resolution not to become the next Dark Lord doesn't look too healthy now, though.

Harry seems incapable of seeing the flaws in a moral system he apparently acquired by reading science fiction and fantasy, barring almost being Sectumsemprad by a very angry wizard. Why does he think that having read books with monomyth plots is sufficient reason to try to act like the heroes of such books - what is he, eleven years old? At the same time, he understands and can nervelessly put to use Quirrell's very subtle lesson in levels of deception. Very odd, that.

Is one of the reasons Quirrell set up those Occlumency lessons that Harry would discover for himself "how reproducible human thoughts were when you reset people back to the same initial conditions and exposed them to the same stimuli" - and thereby come to treat humans as simple machines that one can use like puppets? As a strategy to bring someone over to the Dark Side, that's brilliant.

Then we get to Harry being placed in the same conditions as Lily Potter, and reacting differently - more humanely. Because he reads science fiction! That's outrageous. Surely this kind of narrative based morality, where you imagine what the good protagonist would do and then do that, is going to be a piece of cake for Quirrell to subvert.

Indeterminate at this point. (By which I mean, even if Eliezer didn't intend Quirrel to have those reasons, he could easily make Quirrel have had those reasons.)

The reasons given earlier are quite enough to justify the lessons: Quirrel doesn't want Harry to be easily scanned by either Snape or Dumbledore for obvious reasons, and once he threw his hat in the ring, a neutral third party was the only viable option - and such a neutral third party can only remain neutral by being Obliviated since anyone in the know about Voldemort is, eo ipso, a member of one faction or another.

Just read Chapter 27. Haven't read the original books, but Wikipedia says Snape was a secret agent of good because of his past love for Lily. Nice job turning Snape dark, Harry. Considering your friendships with Draco and Quirrell, I don't see what you're doing out of Slytherin.

Also, the chapter reads a lot like Sword of Good. It's not a bad thing per se because a good story needs to be retold several times before it comes out right, but in this iteration the hero's epiphany that "woah, the world contains a lot of pain, gotta do something about it" came out quite a bit weaker. The protagonist in Sword of Good had a device that relayed the world's pain to him, but Harry has to settle with imagining other people in unfamiliar situations. Eliezer could make this plot point hit harder next time by making his protagonists actually see pain and suffering up close.

No, no, this mistake suggests the opposite. No Slytherin with Harry's preferences, intellect and level of development would ever make such an idiotic mistake. A Ravenclaw might. Harry gave the wise, or at least what he considered to be the correct answer, given very little regard to what he was trying to achieve. Self absorbed know it all.

Don't even let me start on the pretensions crap about knowing what is good, and more importantly what is wise, by reading it in a fantasy book. Even Hermione isn't that much of a git.

My take: That part reads like a fairy tale that we tell children. It doesn't really convey the difference between Harry being naive, having terrible boundaries and generally being emotionally weak and Harry recognizing 'simple on the other side of compexity' that could apply to constructing value systems.

I just finished reading the Russian novel "Lena Squatter and the Paragon of Vengeance" by SF author Leonid Kaganov. It's not exactly a Harry Potter fanfic, but it's very similar to MOR in that it tries to present an explicitly rationalist hero, and IMO Kaganov has handled the task better than Eliezer.

The protagonist is an unattractive and immoral woman whose only strength is extra rationality, which she applies to the sordid and corrupt world of Moscow corporate politics. Using the familiar LW intellectual ammunition - from Pascal's Wager to evolutionary psychology - she gets people fired for talking back to her, gives and takes bribes, blatantly manipulates men (driving one to attempted suicide), and then in the end when she's found the perfect boyfriend her plans neatly backfire, forcing her to kill him and then herself. Lena's exploits are shown with a lot of detail and believability, and overall the book has punched me harder than anything Eliezer wrote. Unfortunately it's unlikely that it will ever be translated into English.

Thanks for trying. Please keep us updated.

I was thinking to introduce some English-speaking audience (represented by i.e. Less Wrong and Hacker News) to Leonid Kaganov for quite some time. I absolutely don't feel able to translate a whole novel (and I haven't read Lena Squatter yet, as it's quite recent) but I think I can pull off translating a short story or a blog post.

The best story of him that I've liked so far is Predator's Epos (2001) which depicts a dramatic incident in space and tries to analyze human ethics through the eyes of an alien studying human epos and comparing it to other species'. The short story, as author noted in his blog, was written on a crunch for a short story competition, which had a theme "a knight quests for saving a princess from a dragon" and, would I say, the author had his fun with the theme. To my mind, the story remains one of his best to date. Definitely best of short stories; I haven't read the more recent of his novels; he might have improved in the recent years, but as of several years ago, I had an opinion that Kaganov is the kind of author for whom the short story format and good crunchtime is an optimum format; the longer stories I read feel watered down. I appreciate that it takes more work and skill to forge a novel while maintaining reader immersion and the pace of the story, and everyone has to start somewhere, but still - I liked his short stories and some of the blog posts best.

Which brings me to the topic that Kaganov raised that I wanted to translate and link to on Hacker News. At the time when he finished Lena Squatter he wrote a very detailed blog post where he said he is at the turning point in his career where the sales of his new book (Lena Squatter) will determine whether he will be able to support his family by starting to write novels full-time or will have to earn money the other way (programming) and have little time for writing. So he asked everyone who would consider reading his books to go buy Lena Squatter in paper form, and not steal it from the internet. The post was very clearly written, addressed nearly every possible concern and the author answered many of the comments (which he always does btw.) Despite of that, the post was met with less than full understanding. So I was going to ask the respective English-speaking audience: do we really have the situation so horribly bad here in Russia that the author, who has written some enjoyable stories, contributed every possible story in the past to the public domain, and now came to depend a little bit on the sales of his book for the well-being of the family, has to beg his fans to not steal his books and yet not meet with total understanding?! Or is this more or less what goes on in the rest of the world as well? The book Lena Squatter seem to have sold well, by the way, exceeding the publisher's very modest expectations, and there should be second printing underway. The rights for publishing should belong to the publisher for several years, I think, but maybe they can be interested in the international edition. At any rate, Kaganov can be expected to be geeking out with author's contracts, not giving an unnecessary extra bit of his rights to the publishers and giving every bit to the public domain ASAP.

Also, I might add that he's an interesting guy, quite a rationalist and sceptic. He've got two or three higher educations; one in Computer Science and the other in Medicine (psychopharmacology)

It looks from my casual observations like the difference between pirated and not pirated (as opposed to plagiarized and not plagiarized, which is a different matter) isn't whether something is in the public domain, but whether it is freely available. As long as it is easy to get a work for free from the author's preferred distribution method, there's little to no incentive to get it with more hassle from a different distribution method. So putting his prior works in the public domain probably isn't getting this author many bonus points, compared to an author who retains copyright or Creative Commons licensing but still makes the work freely readable.

There is no way that he addressed every possible concern to the satisfaction of his audience while charging money for his book. Money is a concern, and while his book might be inexpensive, adopting a general policy of buying inexpensive books when someone asks nicely isn't, and making many individual decisions about when to buy them and when not to isn't either. To an audience accustomed to getting reading material for free, a demand that they shell out money for a new book feels like extortion, and that provokes negative affect indeed. So it does not surprise me that - with the sort of audience he would have cultivated by making his prior works freely available - he'd encounter backlash when attempting to extract cash from them.

His approach might work as a business model in the sense that he's selling books. But of course he is not meeting with "total understanding".

I think that, in the first few chapters, Harry did not give enough credence to the hypothesis that he was simply insane and hallucinating. I think, given the observations he had at the time (his mom claimed her sister was a witch; he got a letter implying the same; a woman levitated his dad and turned into a cat), he should have at least seriously considered it. Certainly those pieces of information are some evidence for magic, but considering what that hypothesis entails — existing scientific knowledge about physics (even at the level of abstraction that we experience directly) is so completely wrong that it's actually possible to make the universe understand human words or intentions, or there's this incredibly advanced technology that looks like it's violating the laws of physics, and it's existed for thousands of years and apparently everyone has forgotten how it works — I think an honest rationalist would have to look into the "I'm cuckoo" hypothesis.

However, on this topic, it seems like there's no good approach for handling the scenario where your brain messes with your internal tests in such a way as to point them invariably at a false positive, i.e. anosognosia.

I agree that a good self-test of the sort you describe would reduce the probability for most kinds of anything-goes insanity, but what sort of test could be used to check against the not-insignificant subset of insanity that specifically acts against self-tests and forces them to return false positive at the highest level?

The answer appears to be no. There were a few articles in Scientific American: Mind about it a while back. Experiments show that the flaw causing stuff like people denying they can't move their arms is part of their logic processing; they proved this by figuring out they could reset their thinking for a short time, at which point people were able to clearly state that they were paralyzed and they were surprised at their earlier thinking.

After a minute, the effect wore off and the patient returned to an earlier state. So the effect appears to short circuit the decision making process on a hardware level.

True. Even if upon witnessing such absurdities he had immediately assumed he was seeing things and demanded to be checked into a mental hospital, he couldn't even be sure that there was really anyone around him to hear, or that he was really saying what he thought he was saying, etc.

But then, if he's that far removed from reality, whatever he's really doing must appear crazy enough to draw the attention of those around him. Maybe he's already in a mental institution... which he imagines to be a school of wizardry!

I think David Hume said something more or less like this when discussing the likelihood of miracles; that if you witnessed a miracle, you ought to conclude you were insane.

I am not sure I buy into this. For one thing, I see a problem with falsifiability. If there is nothing that I could see to convince me that magic might work, I am not objecting to the reality of magic on rational grounds, but as a sort of knee-jerk. It's like the doubleplus loony creationist types who think the devil planted archaeopteryx.

There are reasons I think magic in the Harry Potter sense is not true, reasons that could be argued against (e.g., show me a plausible medium for magic to be carried in). I don't think it would be very rational to make it sort of... axiomatic that magic is false. That seems to in fact be the attitude Eliezer is criticizing in the character of Harry's father.

So yeah, some probability mass goes to the "hallucination/insane" hypothesis, but not very much. Most goes to the "I don't know what's going on here at all, but she did just apparently turn into a cat" hypothesis.

Miracles are one-time events, whereas magic spells are repeatable (in every fictional universe I've seen, anyway).

Addenda:

  1. From the reader's perspective, it doesn't appear that that's what we are supposed to believe (though I'm still wondering...), so I'm tentatively guessing that the mechanism of magic is some kind of technology, and that the in-story universe has the same laws as this one. It does seem implausible that an ancient civilization could have invented technology advanced enough to be indistinguishable from this kind of magic, but that could be different in an alternate history, and it still seems less implausible than any set of physical laws that would actually make this kind of magic a normal, natural thing that a non-industrial civilization could invent/discover.

  2. We are supposed to be wondering why magic works at all, right? It doesn't seem like Eliezer to expect us to be satisfied with an Inherently Mysterious phenomenon at the center of the story, even if it's a story based on someone else's fictional world that already had that feature... but I don't know, maybe it's a demonstration that, no matter how ridiculous the rules are, rationality will still allow you to win.

    But I'm still hoping that magic will be explained at some point, and I'm still looking for clues about it.

I think magic will be explained as an addition onto physics: a new "force" is involved, but still behaves in an intelligible way. I can't imagine how the MoR series would explain the magic exhibited thus far as coming from current physical understanding.

Unless the magicians control quantum wavefunctions directly, or something like that. Or Harry is a brain in a vat.

I think something like "brain in a vat" is the best inference from observing magic. [EDITED to add: of course I mean after getting very good evidence against deception, insanity, etc.]

More precisely: if you find evidence that something deeply embedded in the universe is best understood at something like the level of human concepts -- it matters what words you say, whether you really hate someone else as you say them, etc. -- then you should assign more probability to the hypothesis that the-universe-as-it-now-is was made, or at least heavily influenced, by someone or something with a mind (or minds) somewhat like ours. That could be a god, a graduate student in another universe with a big computer, superintelligent aliens or AIs who've messed with the fabric of reality in our part of the world, or any number of other things.

In a manner of speaking this is obviously correct for the Potterverse (either Rowling's or Yudkowsky's): in that universe, magic works; and indeed that universe was designed by an intelligent being or beings, namely Rowling or Rowling+Yudkowsky. It probably doesn't work "internally" for the original Potterverse -- I've no idea whether Rowling has any particular position on whether within the stories the world should be thought of as created by intelligent beings -- but I'm guessing that it does for Eliezer's.

I'm not convinced that concluding one is in a simulation is really the best bet here. A simulation would have a terrible amount of trouble specifying these effects. If for example, I have a simulation for say just our local system, how the heck are the people running the simulation easily going to be able to specify emotional states or the like? The only possible explanation I can have for this is that the simulation was originally started with humans having certain (simulated) brain structure and that structure is the type of structure that wizards have. Other humans can't do it because their structure isn't of the type the simulation recognizes to trigger magic.

I agree. This is why I think the Hogwarts letter is charmed to make itself sound more plausible than it should be (which would be a sensible way to ease the transition for muggleborns). Harry explicitly wonders where his own certainty that magic is real comes from and doesn't get an answer via introspection. That sounds like the effect of a weak charm to me.

I really enjoyed the series and hope it continues. I have a few comments.

Eliezer had already stated that one intention of his was to make writing fun again, while writing his rationality book. Hence, I guess once that boost is achieved, this litlle jewel will probably lie around unattended for a while.

If the other, more important, purpose was to raise the sanity waterline, then regular updates might be expected as this would be a serious attempt at reaching people through other means.

Doing a quick drake equation analysis of this strategy

P(Positive outcome of singularity) = P(someone reading fanfiction) P(ve reading harry potter fanfiction|person reads fanfiction) P(ve liking it|all of above) P(ve grokking the concepts behind it|all of the above) P(increasing knowledge of rationality| all of the above) P(ve becoming awesome|all of above) P(ve remaining good|all of above) * P(person actually contributing in new ways to a positive singularity)

The first probabilities are high. Harry Potter is the best selling series. Also, it leaves many readers hungering for more. So, more than usual number of readers would seek to read fanfiction stories. So, we're good there.

Twilight has a lot of fanfiction. Googling it puts it slightly lower than harry potter. But the other factors following possibly dominate.

Harry Potter is a bildungsroman, a growing up tale. In HP&MOR, the rationality of Harry is at a high level, while his emotional maturity is, hopefully, slowly increased. On the other hand, Hermione and Drako will be having their rationality updated. Harry is also probably much easier for Eliezer to write compared to a twlight fic. Harry potter is a school story and it is easier to bring in lectures in that format.

I guess somebody could take on the twilight torch also. Once, that is done, The Bayesian conspiracy shall have total domination ! Boys and Girls !

Among those who read the fiction, the probability of people liking it is quite high. I've recommended it to a couple of friends and they have liked it. But the inherent concept of teaching a lesson is quite visible.

Among those liking it, how many grok the concepts? That is the biggie and here again, the link to the sequences helps. I scanned the reviews and every 30 or so reviews, I read one that mentions the sequences. 3% is not a bad number to have here. I just hope it would be more.

After they grok the concepts and read the sequences, and later the rationality book that comes out, then ofcourse, they are in the real league an it is upto the lesswrong community to make sure they stay interested and contribute to better outcomes in the future.

One concern is strongly rational people going bad, which might be dealt with in the story itself. I hope that Draco is turned to the light and many people who began their rationality journey with this story, remember that when they become CEO, Prime Minister or King.

I think any big contributions are likely to come from HPMoR readers who are attracted to LW, become a part of this community, and then go on to do good stuff. HPMoR is just the gateway drug.

Then there's the more diffuse sanity waterline effect of lots of HPMoR readers becoming somewhat more rational, and more receptive to big important ideas wherever they encounter them. Sci-fi has had that kind of effect on the development of a lot of people here, and this story can extend that kind of influence to a new audience via Harry Potter. Plus, in this case Eliezer got to fill the story with the ideas and themes that he considers most important.

Several speculations/thoughts/questions:

First, did baby!Harry actually in fact survive the killing curse? ie, perhaps the curse successfully detached baby-Harry's-soul (presuming that something like "souls" exist in MoR... given the presence of Horcruxes, I'll tentatively assume yes), but the body was immediately made into a Horcrux... so Voldemort-soul-shard effectively inhabited that body. Essentially Rationalist!Harry is actually more like what Voldemort would have been like if raised in a loving and sci-fi and science loving family.

The Hat did say that if there was bits of the Dark Lord's mind there in addition to Harry, it would have noticed the extra "passenger"... But in this case there really is only one mind/soul/whatever. The catch is that mini-mort is all that's there.

This brings up the possibility of if this was an accident or deliberate. Perhaps Voldemort actually deliberately planned/faked his apparent "death"?

(Possible related, well, possibility: How do "we"/they actually know Voldemort even used the Killing Curse that night, as opposed to doing some other thing? ie, how is it known that he is the Boy Who Survived the Killing Curse in the first place?)

Further speculation: When Quirrellmort was lecturing in class about how he used to want to be a Dark Lord, but now finds that he really just wants to teach how to fight and such... perhaps that's a literal statement of fact? ie, does he even desire to "rise again as the Dark Lord Voldemort", or is this what he actually wants now?

Further further thoughts: Does Dumbledore know that Quirrell is really Voldemort under-the-hood? Not just knowing "there's something odd here", but actually really knowing that as fact?

This is awesome. Probably not where the story's actually headed, but it would create a cool Vader-Skywalker kind of relationship and explain what Voldemort is trying to accomplish with Harry. If he wants his Harry-shard to finish the job of becoming Dark Lord, then it makes sense to come to Hogwarts to be Harry's mentor (and to be disgusted by Harry's ambition to be a scientist).

In canon, before he became Lord Voldemort, Tom Riddle demanded that Dumbledore give him the Defense Against the Dark Arts position, and the "jinx" on the position came about when Dumbledore refused. So teaching at Hogwarts is, indeed, something Voldemort has always wanted to do.

That's a good point... though if I recall, he is just known as The-Boy-Who-Lived. In canon, it's not revealed until book 4 that he is the only one to have ever survived the killing curse, in particular, and it's Znq-Rlr Zbbql who says this (though, in truth, it was Onegl Pebhpu We.). Onegl Pebhpu is a highly loyal Death Eater who had been in contact with Lord Voldemort, so maybe the dark lord just told him? Though it's probably more likely that everyone just assumed Voldemort had used his favorite curse.

What bugs me is how they know that Harry is the first and only person to have ever survived that curse. I mean surely, sometime in the entire history of wizards and witches, somebody has sacrificed themself for a loved one who was then Abracadabra'd (i.e. did just what Lily did). /shrug

The hate that the Dark Lord Potter forum has on MoR is getting more than a bit amusing.

Also, perhaps it's me, but I see the story as a thinly veiled commercial for the author's blog/institute, which breaks the "doing this for pleasure and not profit" fanfiction model (as well as being a subtext that breaks the fourth wall for several readers). The author is almost certainly deriving commercial benefit from J. K. Rowling's intellectual property and his exploitation of the popularity of her fandom by routing eyeballs to his site and building his own personal fame as a voice in the field of AI. I wouldn't be surprised if his story has bumped traffic to his blog/website by an order of magnitude or two. In many regards, this practice is worse than a Cassandra Clare or Jim Bernheimer pitching their original fiction novels on their fanfiction sites, since neither author makes a living off their writing.

This story isn't parody in the traditional sense, so it's possible that a court would consider it as not falling within this protected class of derivative works. Indeed, if the legal hammer were to fall on this story, it could have fallout: consider that a single CAD letter, if sufficiently broad in scope, to the owners of fanfiction.net could effectively shut down the fandom.

As Louie commented upon hearing this: "I just love the fountains of money that have been bursting through [SIAI]'s doors ever since the beginning of this fic". Not.

That thread is an interesting read. Fun to see people taking this so seriously.

Personally I just like that it is educational material presented in a fun to read fashion that pokes fun at a rather silly story / fictional universe that has been forced upon us all by the engines of cultural osmosis. I have no problem with HP used as a cheap mnemonic device to memorize and illustrate a set of concepts that everyone should know but most people don't. I also don't have a problem with using it as a cheap advertising gimmick to get people to pay attention to matters that they should be paying attention to but don't. The annoyance of DLP folks at this is understandable, but somewhat hilarious from a perspective that thinks of there as being more important nerdy things to obsess over in life.

What happened to the Harry from Chapter 6?

"Um," Harry said, "can we go get the healer's kit now?"

McGonagall paused, and looked back at him steadily. "And if I say no, it's too expensive and you won't need it, what happens?"

Harry's face twisted in bitterness. "Exactly what you're thinking, Professor McGonagall. Exactly what you're thinking. I conclude you're another crazy adult I can't talk to, and I start planning how to get my hands on a healer's kit anyway."

A time turner is a superior to a healer's kit in very nearly every way and by a huge margin. Yet all Harry does when he loses free access to his time turner he sulks a little and that's all. He doesn't plan at all! I don't even recall one line of introspection on the subject! It takes very little ingenuity to to react:

"Harry, give me your time t..."

shit. shit. shit. Activate time turner. Escape. Then, he can spend five minutes and think up a dozen ways to retain time travel capability. Let me see...

  • Create a fake...
    • Lie to Hermione to get assistance?
    • Transfiguration not likely to work, given the teacher responsible.
  • assume that wizarding security is crap and guess (correctly) that he can probably steal one if needed...
  • actually leave Hogwarts because the time turner is more important and money can buy a better education anyway.
  • Ask Fred and George to discover a way for him to hide, to give him more time to plan.
  • Leave Hogwarts for a week.
    • Fill Gringots with silver.
    • Use money to buy a time turner on the black market
    • Also buy that hand-light that Malfoy bought.
    • And in general a stockpile of the most powerful and useful artifacts available.
    • And the best trunk that can be found anywhere or created for cash.
    • Return to Hogwarts if they will accept him after the week is up. (Or, for that matter, do it in the holidays. There isn't that much of a rush.)
    • If circumstances demand, buy an education from one (or all) of the other schools.
    • Hire all the best tutors available for all subjects and use them to supplement school education with or without the cooperation of any teacher at the school, further insulating him from the ability of the teachers to f@#% with him or take his stuff.

Really... the best Harry can come up with is to say "that's not fair"? WTF?

First, Harry discovered a gag beverage that he thought could be a key to power, although he quickly realized the Comed-Tea wasn't as powerful as it seemed. A few days later he fell in love with a device that is sometimes given to students who want to take extra classes, although he has since discovered some limits to its powers. If he goes rogue over his Time-Turner's crippleware, then who knows how much other cool and useful magical stuff he will miss out on, and how much trouble he'll be in.

Plus, McGonagall had him cornered when she confronted him about returning the Time-Turner - whatever he tried to do, she'd see it. Also, McGonagall had earned some degree of trust & respect from Harry, she's correct about Harry repeatedly misusing the Time-Turner, and she'd already warned him that they'd take it away. So it's not unreasonable to go along with the punishment, and try to earn her trust back so that his Time-Turner can be restored later on.

There is NO DOWN SIDE!

It may be best to hand over the time turner but you do so after having a chance to think it through. Time turner. Plan. Decide that it is better to hand over the device for now. Write your analysis down. Give it to yourself at the appropriate time. (And give it to yourself again to make the loop stable.)

If you genuinely think this is a smart thing to do in real life, it makes me seriously worry about your safety and the safety of people around you.

I have offended you by questioning the rationality of your fictional persona. My own safety is not in any danger. Every other exceptional use that Harry put the device to is risky and I would not do any of them. But giving himself a chance to think through his options in a way that would not be detected by anyone else is the trivially correct strategic option.

My own safety is secure in the short term, and medium term (human life span) but for the long term the threats to my life are human mortality and existential risk. And that's kind of what I've been counting on you to take care of (with any contribution that I could hope to make purely financial). That being the case, this conversation is quite literally scaring me. I'm not quite there yet, but the key quote from Snape is at least springing to my mind: "And I no longer trust your cunning."

Examples of stupid things to do with a Time Turner:

  • Throw pies at people through misguided altruism. It would be better to let them break your finger. You're at Hogwarts... a 5th year Luna could fix it.
  • Have a dramatic stand off over a rememberall. If it is so important... use the time turner to find and or steal the thing beforehand and leave it somewhere Neville will find. I mean seriously... using a time turner in a way that is detectable is for emergencies!
  • Disappearing acts from a class room. Of all the things to do with a Time Turner in that situation making a bigger scene is not one of them. At the very least, if you must refuse to be bullied, write yourself a note telling yourself to not attend potions and make another arrangement. It would be much easier to convince Dumbledore to allow Harry to hire potion tutors than have a full on confrontation.
  • Not using the time turner to go back and prevent the entire situation, after writing a great big essay to your past self on what happens if you mess with those in power.

Now, all the above mistakes are credible for Harry to make. At least, they fit the needs of the story. But using the turner to give yourself time to think at a critical moment... not on the list. And make no mistake, giving up one of the most powerful super-powers (even in the weakened 6h form) is an extremely critical moment.

But now another lesson from Harry Potter: MOR occurs to me: Always be sure you know exactly what you are both talking about. I may well be missing Eliezer's real message.

If you genuinely think this is a smart thing to do in real life, it makes me seriously worry about your safety and the safety of people around you.

What are we really talking about here? Being as EY may be several levels ahead of me the intended 'this' could be "implying that a respected authority is obviously wrong without a clear benefit to yourself". That would make for extremely good advice, and a valid concern. Fortunately I for most part avoid that in real life. It does cost me and I do limit my options such that my environment doesn't put me in that situation too often. One way to ensure my safety is to not put myself in situations that prompt risk taking. It isn't optimal, except in the bounded sense, but it does work.

You seem to misunderstand how the time-turner works (or at least, how it's been suggested it works). You don't get to overwrite anything; the universe doesn't "end up in" a stable state that results from using it; there isn't any meta-time (or at least, we've seen nothing to suggest such). If he were going to use the time turner to give himself advice, he would have already gotten the advice. And having used the time-turner right there and visibly, he couldn't use it "later not use it there" and have his going back in time undetectable.

A possible way he could use the time turner to help himself in this case would be to ask to go to the bathroom or somesuch, use the time turner, use the extra time to think, and then return to the room shortly after he left having thought about things.

(Edit: But this would be pretty obvious, and McGonagall probably wouldn't let him leave the room with the time turner in any case.)

My interpretation of the "DO NOT MESS WITH TIME" incident was that you can try setting things up so that temporal consistency implies the result you want, but actually ruling out every other possibility whatever, including vast classes of outcomes you never even imagined, is next to impossible, at least for an 11-year-old boy, however smart.

Harry's error in the experiment was responding to "DO NOT MESS WITH TIME" with the same. If he didn't have the property of responding to that message with the same, that message wouldn't appear.

Actually, this whole consistency-based time travel seems to be an extremely expressive thought experiment infrastructure for thinking about Newcomb-like problems and decision theories able to deal with them. Maybe I should do a top-level post on that (I don't have a sufficiently clear picture of the setting, so I might be wrong about its potential)... Though I consider that happening unlikely, so other people who understand UDT are welcome to try.

My interpretation of the "DO NOT MESS WITH TIME" incident was that you can try setting things up so that temporal consistency implies the result you want, but actually ruling out every other possibility whatever, including vast classes of outcomes you never even imagined, is next to impossible, at least for an 11-year-old boy, however smart. It hadn't even occurred to him that there was a problem in his reasoning when he tried the experiment that gave him "the scariest result ever in the history of science". Temporal consistency in the presence of time loops is another blind idiot god, far more swift and powerful than evolution.

I think you summed that up perfectly. I would have liked to see a little more of that explanation in the Fan Fic. It would make the story feel more natural and also be a perfect excuse to include the 'blind idiot god' kind of message.

Anyway, he still has the Time-Turner. All that stands between him and it is a magical lock. How difficult can that be for him to get around?

Without Hermione backing him up? I think he'd struggle. Harry just isn't that smart! He really should be spending more time sweet talking her. Well intentioned genius with ambition that doesn't involve gaining power... just the kind of ally Harry needs.

No, actually what stands between him and it is the author's necessity not to unbalance the plot by giving him a get-out-of-jail-free card.

once McGonagall sees Harry disappear, he can't undo it.

Sounds like UDT might be applicable here. Here's a time-traveling version of Counterfactual Mugging:

Harry appears to McGonagall and tells her, "If you give me 1 Galleon now, I'll go back in time and hand you 100 Galleons an hour ago." Suppose McGonagall does not recall being handed 100 Galleons an hour ago. What should she do?

Here's my analysis. Suppose McGonagall decides not to give Harry 1 Galleon, then there are two possible consistent timelines for this universe. One where McGonagall gets 100 Galleons, and one where she doesn't. How does the universe "choose" which one becomes reality? I don't know but let's say that the two possibilities have equal chance of being true, or get equal amount of "reality juice".

Given the above it seems clear that McGonagall would prefer to have pre-committed to "give 1 Galleon even if not handed 100 Galleons an hour ago" since that would make the "not get 100 Galleons" timeline inconsistent. I think that's also UDT's output (although I haven't written down the math to make sure).

ETA: I didn't follow the previous discussion closely, so this might not apply at all to it. Hopefully, in that case the above is of interest in its own right. :)

comment by topynate · 2010-07-01T00:20:02.142Z · score: 5 (5 votes) · LW · GW

Seems straightforward to me. McGonagall knows that she does not recall being handed 100 Galleons an hour ago, so the three states of the world with high probability are: 1) She is not in a universe where she will hand Harry 1 Galleon, 2) She is in a universe where she hands Harry 1 Galleon and Harry breaks the agreement, or 3) She is in a universe where she hands Harry 1 Galleon and Harry keeps the agreement in a way that leaves her unable to recall this happening. By not handing Harry a Galleon, she will ensure that she is in universe 1. By handing Harry a Galleon, she will find herself in universe 2 or 3. She should therefore give Harry a Galleon if she judges it less than 99 times more likely that Harry will break the agreement than fulfil it in a way consistent with her experience.

As Harry has access to a time machine, he doesn't need to decide to give her 100 Galleons before he gets the 1 Galleon, so the situation is quite different to one based on predicting her actions, as Omega does in the Counterfactual Mugging. Rather it has most of the properties of the forward-time version of the gambit: "If you give me 1 Galleon now, I'll hand you 100 Galleons in one hour", except that McGonagall has a big piece of evidence that the promise will be broken, namely that she doesn't remember it being kept.

Precommit, give him the Galleon, then reach in her bag to get the 100 Galleons. (She must have been Obliviated; otherwise, she would remember.)

You can actually get around a lot of the problems with time travel by taking advantage of the difference between observation and reality. For instance, if you see one of your friends die, you can go back in time, save him, then plant a fake double so you still have the same observations.

Returning back to 6(grand)parent, I can say, that imposing any condition on a stable state of time loop (but initial conditions before time loop) seems unphysical. All in all, thought experiments with time loops are interesting, but their validity is highly questionable.

Ok. Almost pure physics.

A trolley is running out of control down a track. In its path are 5 people who have been tied to the track by a mad physicist. Fortunately, if trolley ran down different track, it would activate timeturner that would send it 10 seconds back in time and then trolly would flip a switch, which will lead the trolley down a different track to timeturner. And also a bystander runs to flip a switch.

Possible stable states.

  1. Bystander stops and wait for trolley to appear from nowhere. Trolley kills 5.

  2. Bystander stops and wait for trolley to appear from nowhere. Trolley appears from nowhere and flips the switch, then original trolley runs to timeturner and disappears.

  3. Trolley appears from nowhere kills bystander, which almost managed to reach the switch, and flips the switch, then original trolley runs to timeturner and disappears.

  4. Bystander appears from nowhere and flips the switch, then original bystander runs to timeturner and disappears. Trolley run past deactivated timeturner.

  5. Bystander appears from nowhere shouts "watch your step!" and fails to flip switch in time, original bystander looks on timetraveller, missteps and falls, then manages to activate timeturner and disappears. Trolley kills 5.

  6. Bystander appears from nowhere shouts "careful!" and flips switch, original bystander looks on timetraveller, missteps, but manages to not fall, then activates timeturner and disappears. Trolley run past deactivated timeturner.

  7. Bystander appears from nowhere looks on trolley, shouts "damn! too late" and fails to flip switch in time, original bystander hearing that tries to run faster, missteps and falls, then activates timeturner and disappears. Trolley kills 5.

  8. Bystander appears from nowhere, shouts "Shout, what I shouting now, it is very important!" and flips switch, original bystander activates timeturner and disappears. Trolley runs past deactivated timeturner.


Even in those rigid conditions stable states can be numerous without any improbable events. But yes, maybe you are right, because amount of information-from-nowhere must be limited by communication channel bandwidth (spoken or written speach, nonverbal actions of future-agent, agent's memory throughput), thus rendering stable states in principle analyzable.

This is actually more rational than what you are advocating.

Are you sure you understand what I'm advocating? Your claim here suggests to me that you do not.

The most probable outcome of the thought process I outlined, and I say most probable because this is what my reasoning concluded but Harry is smarter than me, is that he will go and earn enough enough money to buy a time turner just in case. I aren't advocating the use of the time turner to make reckless experiments or any of the non-authorized uses that Harry had previously used the device for. I actually made it quite clear what I thought of clever experimentation when explaining the note I would send myself. "Arrogant git" was the key phrase if I recall.

What kind of usage is sane? Emergency usage. For example, I would advocate the use of a time turner when locked in a room being tortured and at a high risk of suicide if I do not prevent it. (I liked the touch with the destroying all sharp objects too.) I would also advocate the use for saving lives (including his own depending on circumstances) with minimalist interventions, many of which would be not at all experimental given what he has already safely gotten away with. It would also be extremely valuable in the reduction of risk to have an extra 36 hours available for emergency use. Many threats to Harry's world optimisation plans will come with some warning. Impending attack of some sort, etc. Having a turner on hand means that he would be able to take more time to make preparations or give th device to McGonnagal in the emergency situation and allow her to prepare. As far as either myself or Harry know she isn't wise enough to have one on hand herself.

A time turner is a device that is massively useful and it is massively useful even if you use it conservatively and take no risks with it. Having one on hand does not make bad things happen unless you know you will be unable to control your foolish impulses. This is not Harry's reasoning.

If Harry does not spend at least five minutes thinking through his priorities (let me emphasise that again, spend five minutes) and considering how to acquire (ie. buy) a time turner then both he and the author are making a big mistake. That is not* more rational. It is a rationalization of a decision that was originally made for the purposes of plot balance.

The reasonable solution is clearly for Harry to do is to put "buy time turner" down on his to do list right next to "become ridiculously rich in a week". It is an obvious smart thing to do but the reader understands why Harry can't really follow through with these plans for story purposes. Having them judged "not a pressing priority" is a credible explanation.

In all the previous time related events, things worked out how they did because the situation in which Harry did not use the time turner was not stable. If Harry was different (for example, by being Hermione or by not having a Time Turner) then the stable, 'final version' given by the universe-time-loop-processor would be the simple one where he doesn't go mess with stuff. But it wasn't.

He did the same thing every time he used the time turner. I mean every time, even the times when he was being a good boy and using it to manage sleep. the universe doesn't care whether it is a conversation with McGonnagal, juggling bullies and pies, someone falling off the roof or just bed time.

What does matter to the universe is whether the agent in the time loop is interacting with the time loop in a way that is complex and improbable. That is, factoring large primes should give unpredictable outcomes, long detailed tricks like throwing pies and playing with bullies should be slightly safer, giving yourself a time out simpler again and pre-sheduled study and sleep breaks right down at the bottom of the scale.

I argue that all the instance of time turner differ use differ only in degree. There are many things to do with a time turner that are far, far less disruptive, complex or unstable than what Hermione did when attending multiple classes. Given her interaction with other people who would be encountering her other self there are butterfly effects that would need to be resolved by the system. If Harry set up a smart system to communicate with himself unobtrusively things may be simpler to predict. He could send himself SMS messages (when outside Hogwarts) or use one of those coins to send messages.

They're both based on the same premise. The timeline is changeable but highly resistant. Humans can't change it (that's the short story) but there are two superhuman sides (called Snakes and Spiders, but never seen onstage) which recruit humans who are willing to be cut out of their timelines just before they die.

I found Vladimir's utterance (I'm not sure of word's connotations, I use it in pragmatics sense) incomprehensible on my current level of understanding his intentions and his ways of expressing toughts. So I've took literal meaning of his words into current context. However, beside joke part my message points on difficulties in dealing with stable states of closed time loops (the thing).

Those closed time loops are weird. I considered timeturing before outcome, but, yes, even in that case one can be told by one's timeturned twin, that all is set up for good outcome. And timeturing after desired outcome... should be done unconditionally, as you can't know it is not you who caused this outcome. Weird.

Definitely weird. A related consideration is that I would always give reasons for any advice I give my former self. That cuts off a large swath of potential stable loops that consist of me giving myself advice for absolutely no reason at all except that it happens to be stable. The better the reasons I have been given myself the less likely it is that the self perpetuating cycle is a completely arbitrary cycle.

For example, I wouldn't have sent back "Don't mess with time". I would have sent "the universe doesn't particularly care about your rules and plans you arrogant little git! What's more likely, guessing your way through 128 bit encryption or something seriously nasty that distracts you from your games, such as ? That's right. Think." (Yes, I'd include the 'arrogant git' part. That is information I would clearly need to be reminded of!)

Now, not all scary situations give me the chance to write an explanation but a large swath of the probability mass does. While I would still follow the hastily written directive I would also know that to write that particularly message something really bad must be happening. Without having a predetermined policy for giving details I would have no idea whether the message meant something bad almost happened or not. (It also means that I am far less likely to get such a message - I'll probably get one of the many possible detailed messages.)

The problem is that you aren't source of advice, you are one of constraints to be satisfied. Any message, that you will reproduce with picometer precision and that will create stable state, will do. Precision isn't a problem in deterministic world, and maybe in quantum one too (if our neurons are sufficiently classical), but I'm hesitant to estimate influence of one's preferences on stable state.

I don't exactly fit your set since I had seen LW before, but there's some good reason that I should be included in your sample. Explanation follows: I had read most of the sequences before (and frankly didn't learn that much from them. A handful of cogsci and psych classes along with a fair bit of phil sci gives one a lot of the same material) and had previously read some of Eliezer's fiction. I hadn't really taken that detailed a look at LW as a whole, until HPMR. That was partially due to a conversation with a friend that went something like

Friend: So who is the author of this stuff? JZ: He's Eliezer Yudkowsky who is an all around very bright guy. He has some a bit off ideas about the Singularity. Friend: What evidence do you have of that he's bright and not just a good fiction writer? The one thing you've mentioned is something you disagree with. JZ: Um, let me get back to you.

Then when reading I felt a need to register an account to make a comment, and then it has been downhill from there (I just linked an LW post to a friend who said that she refused to read it because "I'm not sure I'm willing to let myself -oh god oh god- be sucked into Less Wrong. I have heard it wastes time like tvtropes on crack." I'm not sure if that's a good or a bad thing).

I've linked HPMR to a fair number of people, and it seems to be having some impact on some of them. Indeed, it seems that it is quite effective at getting through defense mechanisms that some people have against being more rational, because the arguments aren't being coached in an obvious way of trying to just present what is wrong with their thinking processes. I'm running into concerns about whether linking HPMR to people without telling them about that is ethical or not.

"Well-armed" makes a little more sense, but I still don't think it's a good analogy. Lions destroy people who aren't well-armed, so it's disingenous for a well-armed person to say that a fair procedure for who lives is to let the lions attack and see who survives. Truth destroys false ideas, not people, and people frequently don't know in advance which ideas will be destroyed by the truth. People, even rational ones, are often wrong in their predictions, unlike the well-armed man.

A precommitment to letting experiments and truth decide what ideas will survive doesn't stack the deck in your favor, unlike in the lions example. The whole point is that you are willing to take the chance of having your ideas die, as long as the true ideas survive.

I think you could say that the truth does destroy people. You can't be the same person once you've really accepted an entirely new, important idea, and rejected an old belief.

When someone says "that which should be destroyed by the truth should be" and he's talking to a Christian or a white supremacist or thousand other people defined by the silly idea they take very seriously, you are often asking them to do something a lot more scary than go up against a lion.

If you've already seen the truth and accepted it, the deck is as stacked as it could be. And if you haven't but are otherwise making your bet rationally, while the other is not, then you've still got a lot better chance.

You're not very rational for a bunch of extreme rationalists, are you? It's only possible to answer this survey if you register for the site, so excluding nearly all possible commenters (there is science on this) and presumably an even greater proportion of those who are uninterested in the ideas in LW.

  2. I started to read through the Sequences, but they rapidly set off my nutcase detectors. So you might want to do something about that. But I was interested in who had written the fan fiction; and quickly found this thread.
  3. I have learnt that there is a community of extreme rationalists who believe that humanity will soon use science to cheat death. Actually, I already knew that. But I have found one of their websites. I was already familiar with most of the philosophical tropes explored in HPMoR; I don't think it would be anything like such a good story otherwise, and I think most of the readership will be people who are already relatively rational. So in terms of 'raising the sanity waterline', an endeavour which seems to be entirely worthwhile, I am not sure it will do that.

I've seen plenty of nutcase-stuff in which the math wasn't gibberish - it was correct as math but was simply window-dressing for the nutcase argument. Sometimes, it seems that EY is just using it as garnish for his arguments as well. So, I think that there is a kernel of truth in what GuySrinivasan said about the mathiness of the site. It fits the pattern.

Which is not to say that EY is a nutcase. Those nutcase detectors may be returning false positives. But that doesn't mean that the nutcase detectors are defective.

And I think that would make Blaise the quadruple agent, with Dumbledore as the fourth faction, and Quirrell aware of the entire thing, masterminding his own little stanford prison experiment in order to achieve whatever ends he's ultimately aiming for.

It was interesting to see how deeply Harry got into his "General Chaos" role in this light. (Also, I think Ch. 32 was the first time I've laughed out loud over the story in a while. It was getting pretty serious and this was way more fun. The "vader/emperor voices"... I was busting up! I think this kind of hilarity at the beginning is part of why the story took off the way it did.)

Plotwise, I've been wondering lately if Eliezer might be laying the groundwork for Voldemort to turn out to actually be the good guy and maybe Harry's true challenge as a protagonist will be to recognize that rationalist!Voldemort will actually turn out to be good for the world, and deserves to be supported. I could image the army lessons turning out to have a positive global outcome if they ended in the right way, which would add a bit of support to this theory.

This is how one of Eliezer's early stories turned out: "The Sword of Good".

(There are some traces of that story in MoR - Harry early on not engaging in moral relativism is similar to the hero's final understanding of the evil of the status quo of the fantasy world. But ultimately I think Quirrelmort will be evil. Voldemort killing the entire dojo and sparing only his friend is a mortal sin and Quirrel does not exhibit the kind of heroic remorse necessary to make up for mass & serial murder. Which reminds me, we don't know who Voldemort killed to get the Horcrux on Pioneer. A security guard, probably.)

Chapter 30-31: Was there a more sophisticated basic idea than appearing to be incompetent, then playing possum? I'd have expected one of the other two armies to expend a second (double tap) sleep spell on the downed, given that Neville came up with the same tactic later on.

Also, nice touch writing Neville as Bean without using a sledgehammer on the parallel.

Well, Hermione wasn't just appearing to be incompetent in the sense of "too stupid to calculate the correct solution;" she was appearing to be irrational in the sense of "too self-righteous to want to calculate the correct solution."

Also, note that Hermione actually did stay true to her goals: her possum tactic allowed her to avoid "unfairly" choosing who to attack first. By waiting until most other players had been sleepified, she was able to attack only the strongest or luckiest survivors, rather than the soldiers controlled by someone that she personally disliked. She was able to both win the game and stay true to her values because she (somehow) was much better at working in groups than Draco or Harry. One wonders how a girl who had no social skills in Chapter 3 suddenly became so socially adept -- has she been reading books on how to get along with people?

It's more that both Harry and Draco were mentally handicapped here. Draco has the glamorous dream of being the dark overlord who controls everything from the top, his orders unquestioned and his name spoken in hushed tones. Harry has the habit of trying to think up an ingenious plan by himself, and it just didn't occur to him to get other people in his army to do strategy planning. Tactics, sure, but not strategy.

Hermione, in contrast, is perfectly used to learning from others, and doesn't have particularly grandiose ambitions. And maybe Quirrell casually hinted that some of the people in her army were good at planning things. It seems the sort of thing he'd do, to make his plan less brittle.

Was there a more sophisticated basic idea than appearing to be incompetent, then playing possum?

As I argue in the reviews for chapter 31, Hermione herself was surely not playing possum, and likely neither were her 6 soldiers. That was not their idea. (Whether Nevile is smart enough to tell Harry, or whether one of the other armies will think of it in time for battle 2, is a question for the future.)

There were 24 people per army, and 11 of Sunshine came at Harry and 12 at Draco. And Harry & Draco had their realization of what happened when they remembered that Sunshine's soldiers went down immediately at the first shot. They were playing possum (all but Hermione, who didn't want to risk it).

The 6 soldiers left is after the battle of Sunshine's return, after they've already taken Potter hostage.

Read up to Chapter 21, commenting on chapter 2. Prediction about the physics of HP:MR.

Harry is mistaken about McGonagall's transformation into a cat breaking conservation of energy; indeed, it seems to me that he is not really putting a lot of effort into finding an alternative explanation, but jumping straight to "Everything I thought I knew was wrong". (Perhaps Lord Kelvin's not the only one who gets a charge out of not knowing something; after all Harry has been wanting to do Something Big, and the more laws of physics are broken, the better!) A simple hypothesis which does not break conservation of energy: Rather than McGonagall's human body literally turning into a cat, it is replaced by a cat-body from elsewhere in the universe. McGonagall's human brain continues to operate in its usual fashion (while being physically elsewhere), and this is turned into cat-brain commands by an AI somewhere in the interface. No mass (hence no energy) appears or disappears, there's just an exchange of objects.

Ah yes! You can store the whole human body in a cavity of the cat's body, and vice-versa; lightspeed is no issue - indeed you could run the whole thing at ordinary neural speed. This might even solve the problem of how to order a cat's body around; the Animagus in effect has a cat as an ordinary part of her body, and has learned to operate it the same way she learned to operate her human body.

One problem is the carrying-over of wounds from the animal to the human body, and vice-versa; this does not seem implied by the model, and requires additional explanation. Psycho-somatic damage? Since there a requirement for conscious control of which shape one is in, the opportunities for unconscious failure seem strong.

The concept of switching in itself violates all kinds of fundamental assumptions in physics, so trying to think about it mostly results in nonsense. That's if the switch doesn't actually involve moving A to B and B to A by some path, though; if it does, you naturally pay the relevant costs to maintain conservation laws while switching.

I found this series much harder to enjoy than Eliezer's other works -- for example the Super Happy People story, the Brennan stories, or the Sword of Good story.

I think the issue was that Harry was constantly, perpetually, invariably reacting to everything with shock and outrage. It got... tiresome.

At first, before I knew who the author was, I put this down to simple bad writing. Comments in Chapter 6 suggest that maybe Harry has some severe psychological issues, and that he's deliberately being written as obnoxious and hyperactive in order to meet plot criteria later.

But it's still sort of annoying to read.

I did enjoy the exchange with Draco in Chapter 5, mind.

(I encountered the series several weeks ago, without an attribution for the author. I read through Chapter 6 and stopped. Now that I know it was by Eliezer, I may go back and read a few more chapters.)

I suspect that a main inspiration for writing the story was Eliezer's constant shock and outrage over the fact that Rowling's characters show absolutely no interest in the inner workings of their weird Universe. I vividly remember how outrageous this was for me when I read the originals. Actually, I have only read the first two books, so when I read Eliezer's time-turner scene, I first believed that he invented the artifact and the situation as an over-the-top satire of this phenomenon. Giving young children time-machines so they could attend more classes, yeah right. When I figured out that the whole scene is almost literally copied from the original books, I screamed in shock and outrage just like rationalist Harry did.

It is a work of Harry Potter fanfiction for the following simple reason:

New chapter. I think I'm going to update daily for a while, but no promises.

I'm having trouble making Bella conspicuously luminous because fictional characters in general are more luminous than real people. (Authors have perfect access to knowledge about character minds, and since the dearth of luminosity in real humans isn't known to most authors, they don't restrict the characters' access to this information much if at all.) I've resorted to some tricks, most notably the notebooks - how do people find Bella's visible luminosity?

I wonder if real people could become more luminous by occasionally narrating their thought processes from a third-person perspective, treating themselves like characters that they're writing. If nothing else, it'll be a cute gimmick for getting someone to examine their own motivations.

I tried out my idea, and it worked. It wasn't too spectacular, but it was well worth the effort.

I decided that, in order for this to be a proper test, I would look at something that I wasn't really comfortable with: my shyness and difficulty in social situations. I figure that there had to be some obvious irrationality clunking around my skull there.

I started describing this guy (myself), and laying out the reasons for his social discomfort in a straightforward exposition dump. Several times, I had to pause and ask myself if the explanations actually made sense -- was this true, or an incorrect rationalization by an unreliable narrator? The process was surprisingly adversarial!

I came to two surprising conclusions. First, the deeper cause of a lot of my problems is that I have difficulty quickly finding topics of common interest with most people in most situations, so conversations with strangers tend to end quickly and abruptly, which sucks. A previous thread had advice for improving this skill; I'll see if I can find it, and give it a try.

Second, there's an even deeper problem that underlies my shyness: I want to not be disliked by anyone, but that's paralyzing and leads to crippling shyness. Far better to be more open with my personality, and accept that someone is probably going to be pissed off by any sufficiently cool person. I'm going to try letting my quirkiness out more, since some people seem to find it really charming, and I enjoy it.

Even though this method worked, it seemed pretty much equivalent to the introspection method where you explain something to an imaginary person, while listening to yourself carefully for anything that sounds like bullshit. I think that method is easier since it doesn't require the third-person pronoun shift, which turned out to be superfluous.

Really, the most important things seem to be:

  1. Come up with an explanation for something, and put it into words. Explain clearly, as if your listener doesn't know what you're talking about.

  2. At all times, ask "Is that really true?" Are there any alternate hypotheses? Does it sound like a rationalization? Is it fallacious? Does it sound like motivated stopping? (That's a really common one, I found.)

  3. Be honest. The truth is valuable. You can do stuff with the truth. When you come across a surprising truth, figure out if it's useful. It might be!

So, definitely a worthwhile exercise, but the third person narrative gimmick isn't necessary.

I do something vaguely similar to this: a lot of my introspective thought takes the form of imagined dialogues with someone who I think would take the other side of the argument, or at the very least need convincing. For example, in a lot of my thinking about metaethics recently, (an imaginary construction of) Eliezer gets cast in the dissenting role. This seems to help me avoid arguments I can't justify, though far from perfectly.

I'm skeptical of the claim that most authors don't know that real humans are unluminous. The authors that I have met in person haven't seemed particularly luminous to me, and I see no reason that they would think that people in general would be so. I suppose that they could all model their writing on other writing instead of on the world as it exists, and thus excess luminosity in fiction could quickly propagate, but this seems somewhat implausible.

Because the lack of skill is not transparent.

By way of analogy, it takes a reasonably uncommon bit of knowledge to be aware that human vision includes blind spots and to know how they work. Even though every single human has blind spots (if indeed they can see at all), and can determine the existence of these blind spots through easy tests, many authors will not think to write fictional characters with visual blind spots, because it is not obvious to people going about their ordinary lives and looking at things that they exist. The author knows what's within visual range of the character, and if the character has his or her eyes open, (s)he can see all of those things.

Luminosity is rare. Knowledge that luminosity is rare is rare. Most people trust in naive introspection. They believe the first approximations that pop into their heads when they think about themselves, in the same way that they accept what their visual cortices tell them.

I think I might not get it. How could someone be introspective but not luminous? I haven't put any real effort into reading the luminosity sequence because it seemed so fundamentally obvious to me. It is possible that I am low-level and deceived in ways that I am totally unaware of, but it's always been easy-- trivial, even-- for me to see through my brain's "fake explanations" and understand the actual reasons behind my thoughts or traits.

I am going to assume provisionally that you do not mind answers from people other than Alicorn.

Situations that have probably caused me to become less aware of the true reasons for my thoughts and actions:

  • needing to stand up for myself, i.e., to argue on my own behalf, in what a friend of mine referred to as a "pecking situation," i.e., one where ordinary people without a strong commitment to epistemic purity constantly try to one-up me and each other;

  • needing to sell myself, e.g., in a long series of job interviews or dates;

  • living for months with chronic pain;

  • getting older (I am 49);

  • being very afraid

(end of list).

The changes I found myself required to make to myself over the months and years to become marginally competent in the "pecking situation" almost certainly interfered with my self-awareness though I never despaired of my eventually regaining the self-awareness with enough work.

Something caused me to pay much less attention to my felt sense and my moment-to-moment emotional reactions, and my having lived for years with chronic pain is one of the most likely causes.

There's some "obviousness" to it, yes.

Info on what works for readers and what doesn't would be good

Here goes.

Since I had not read any of the books or seen any of the movies, I lacked confidence that I possessed the prerequisites for reading your fanfic.

It turned out that I did possess the needed prerequisites (for reading Chapter 1) but I almost concluded otherwise and almost stopped reading when I got to the first reference to Charlie because I did not know who Charlie is.

But then a few sentences later it became obvious that Charlie is Bella's father, and I read to the end of the chapter.

In summary, my feedback to you is that this particular reader would have benefitted from a replacing of the first occurance of "Charlie" with "My father, Charlie."

I want to know what happens next :)

Here's what I think will happen:

Zabini stuns himself in the name of Sunshine to create a tie. And here's why:

1) The rest of the school is very partisan about their favorite army, so it's not likely that many are betting on a tie. Zabini (through a proxy or otherwise) put all of his chips on "tie." So he will return to Hell a much richer Prince of Darkness.

1a) "Aftermath" scene: Hogsmeade. Zabini meets his broker. Hogwarts is basically a closed economy, and Zabini has now walked off with the lion's share of the student body's disposable income. He plunks his Bag of Holding on the table. "Take this and convert it to Muggle money. Then go buy unmarked silver bullion..."

2) The three Generals are tied for Quirrell points. Given what we've seen of him in this chapter, Zabini is probably in fourth place, and not too far behind. How many Quirrell points will he get for getting all three generals to play according to his plan? We see Harry and Hermione accepting, and per the Prisoner's Dilemma thing, Harry and Draco had to synchronize their moves ("cooperate") to have a chance against Hermione. This would mean that Draco is also more or less following Zabini's plan. Zabini was able to steer the battle to his personal chosen outcome, so he (as an individual) wins the battle. The betrayal rules+scoring are set up to favor individual objectives rather than army loyalty/collective goals/unity. Zabini has realized this, and acted accordingly.

3) After collecting Quirrell's wish from his come-from-behind victory (which provides a "practical" demonstration of the 2-4-6 Test, since no one, Generals included, expected Zabini to have his own victory conditions), Zabini goes to Dumbledore's office. "Well done, Blaise!" Dumbledore says. "I suppose you're here for your wish..." That is, Dumbledore has offered Zabini a wish if he could steer the battle to a tie, since that would stop a Hogwarts equivalent of a football (soccer) riot, which would be likely if one of the armies won.

4) At the Christmas feast, Dumbledore rises to announce that the three armies are being merged into a Hogwarts Army, and starting at the end of January, the HA will compete in three-way battles with Beauxbatons and Durmstrang. Per the experiment mentioned earlier with the "Eagles" and "Rattlers," the Hogwarts students are united against external foes. He and Quirrell allowed the Headmasters of the other schools to watch the battles using Quirrell screens, and their staffs liked the idea. The mock battles use more magical skills and incorporate more students than Quidditch, and are thus a better encouragement to learning. New rules could be applied to future battles. "You may use any magic item you can make (under teacher or senior-student supervision) in your battles, providing it's not dangerous." "You can use any Potion you can make," etc.

Predictions?

Regarding the note of confusion Harry feels in Chapter 3: the Killing Curse "strikes directly at the soul", but in Voldemort's case it burned his body. More likely he never cast it at Harry Potter, and the burnt hulk they found wasn't him. He learned about the prophecy and, being smart, changed his plans rather than risk fulfilling it.

And the Source of Magic is a UFAI that optimizes the world into stories.

I hope all my predictions turn out wrong. What I want most from this story is to go on being surprised.

Chapter one, when Petunia is talking about how she wanted Lily to use magic to make her prettier:

"And Lily would tell me no, and make up the most ridiculous excuses, like the world would end if she were nice to her sister, or a centaur told her not to - the most ridiculous things, and I hated her for it. And when I had just graduated, I was going out with this boy, Vernon Dursley, he was also fat and he was the only boy who would talk to me in college. And he said he wanted children, and that his first son would be named Dudley. And I thought to myself, what kind of parent names their child Dudley Dursley?

"McGonagall?" Harry said, once they were in the courtyard. He had meant to ask what was going on, but oddly found himself asking an entirely different question instead. "Who was the pale man? The man in the bar with the twitching eye?"

"Hm?" McGonagall said, sounding a bit surprised; perhaps she hadn't expected that question either. "That was Professor Quirrell. He'll be teaching Defense Against the Dark Arts this year at Hogwarts."

"I had the strangest feeling that I knew him..." Harry rubbed his forehead. "And that I shouldn't ought to shake his hand." Like someone he'd known a long time ago, and then been separated from... an unhappy feeling, a sense of loss.

Maybe I was just really unobservant reading the first time around, but rereading is really fun.

Ch 29

"Did you know there's a fourth-year girl in Hufflepuff who's a Metamorphmagus?" said Hermione as they headed toward the Great Hall. "She makes her hair really red, like stopsign red not Weasley red, and when she spilled hot tea on herself she turned into a black-haired boy until she got it under control again."

Chapter 28: I wonder what happens if Harry realizes he's living in fiction, and everything he's dealing with is made of concepts rather than atoms.

Which leads me to think about the people who say that if they found they were living in a simulation, they'd try to get out. Unless the simulation is very similar to the substrate, would it be possible to get out while remaining yourself in any sense?

Back to the story: This might be an argument for checklists: Harry and Hermione should review precautions before they try anything new, should they be doing it without adult supervision. It's possible that the adults should be doing it, too.

However, the story is a good reminder that it can be hard to remember the relevant thing, even if you're very smart.

I don't think Hermione is over-reacting-- remember that they're doing stuff which is not just more potentially dangerous than children that age are permitted to do in our culture, it's more dangerous than what most adults do.

Sure. Escape into another simulation.

More seriously, obviously it's not guaranteed that an organism in a simulation can just create a copy in the outside world. How would a Game of Life organism, made out of glider guns and flashers and whatnot, made an atom-based form of itself?

What it could do is create something isomorphic. Whether this is possible is pretty much the same question as whether humans can make uploads. (Which is the inverse, actually - going from 'reality' to 'simulation'.)

Since around Chapter 20 this is actually my guess for the entire basis of magic that Eliezer is working from. That is... there's a jumble of ideas and tropes that are invented and sequentially stolen by one author after another. Someone tells stories of Vlad Tepis, Bram Stoker comes along... and N iterations later you've got Twilight with vampires having extra chromosomes and clairvoyance.

To understand a magical universe at the deepest level is to see the hands of previous authors influencing your physics and history (and possibly your future if you are in a prequel) plus a "current author" who has a measure of finer grained control over things like plotting and characterization - limited by the audience's willingness to play along.

If this theory of magic is right, rationality in a magical universe should lead you to to become genre-aware, and then the next obvious(?) thing is to go meta genre-aware and start trying to "genre hack" your universe and see if you can "tunnel" into the derivative works (or maybe just get the author to fall in love with you or something).

My current working theory is that Dumbledore as figured out a rough outline of these "magical physics" and has been actively manipulating his reality for decades, with the goal of setting up pre-conditions that could create "authorial change" and/or to make a certain story easy to tell given the facts. The more pointed goal is to cause his universe would branch at a "point of interest" in a direction that, according to fictional tropes, is more likely to be to his own liking.

Based on his revelation about pranking Harry's mother, I've got a (totally unnecessarily detailed) hypothesis about what he may have done to create initial conditions for Harry Potter something like 20 or 30 years before the present story (including setting up an abusive adoptive environment) that got Rowling to pick up the canon universe and give him a victory there.

In the meantime, if the theory is true, the deeper question is whether Voldemort has the same insight, and if he (in keeping with the "bad guys are better leaders" trope) he actually told some of his henchmen about his plan for the world. I think Snape might be genre aware? And the Malfoy's are even better candidates because they could be trying to hack the universe such that Draco is the main character in a fairly standard "magical prince from fallen but ancient family, rising to up to a historically and morally appropriate place in the world". Setting Harry up as Draco's evil arch-nemesis would be a good move in this vein... Harry falls into the Lex Luthor trope and eventually loses because "that's how those stories work".

The only trick is that they are actually in a fanfic about rationality!! I'm not sure if anyone realizes that yet. Maybe Dumbledore does now? Eliezer was more obvious about the story with this bit:

"Indeed," said Dumbledore. "But Harry is the hero, so he may be able to do things that are logically impossible."

Which confirmed my hypothesis some. But my plotting hypothesis will not be supported if Dumbledore doesn't start seriously updating on the "science is starting to apply to magic" facts. I'm kind of curious why he didn't notice that Transfiguration was retconned in the first place. In the face of so much else magical chaos that Eliezer left in place that adjustment is sort of glaring. Noticing possible retcons is one of the nearly necessary skills you'd want to cultivate if you were going to genre hack.

I really hope my hypothesis bears out. I'm aware of no previous work of fiction that jootzed all the way to being genre-aware of its genre-awareness and I think it would be it would be hilarious to read one :-)

My hypothesis is that thus far he's considered poor Alissa to be the most inconsequential thing ever to intrude on his thoughts; and having thought more deeply about what happened with him, Lily, and James when he was a kid, he now decides he ought to her to nip her affections in the bud for clearly stated reasons, rather than letting them fester without suitable closure for, perhaps, an unduly long time as his have. His only closure was that he insulted Lily and felt guilty about it forever (as apparently, from his perspective, this was the only thing standing between him and getting to be with Lily); Alissa's could be the end of school, without the issue ever being directly addressed.

The problem with this hypothesis is that it has Snape thinking that student crushes on teachers are persistent sorts of things, and this isn't typically the case.

Hrm... So far best I can come up with are two possibilities, one more charitable and one less charitable toward Snape:

First: From his conversation with Harry, he perhaps concludes that making one's feelings (or lack theirof) to someone that may have feelings for you absolutely clear rather than leaving it ambiguous may be a good idea. (ie, in his own way, he wanted to protect his student from ending up in a situation similar to himself)

Second: He was sufficiently POed at Harry that he's no longer keeping his agreement to not legilimens the students.

I'm not really assigning all that high credence to either of those hypotheses, but they're more or less all I could come up with so far. So... give us a hint? :)

This is what I figured. And there was the comment by Dumbledore (or Minerva?) that Snape wouldn't hurt Harry because Snape loves Harry's mother. So I'm now assuming that Harry managed to convince Snape that Harry's mother is not love-worthy, which means that Harry is now stripped of that protection.

He tells her to stop staring at him, and doesn't look at her when she comes to see him after class. Perhaps this was because he no longer needs to read her mind, because he's decided to stop reading students' minds, because he was doing so at the headmaster's bidding and he's broken with Dumbledore.

Wildly conjunctive and supported by a hair's breadth of evidence, but I don't have a better guess. Nothing else seems likely to have a dramatic effect on Harry's story.

Analysis of Harry's conversation with Snape in ch. 27.

"If he were a friend," Harry said, "all the more reason to forgive him."

Possible Snape thoughts: "He implies that I wasn't even a friend of She. How dare he!?" ... consideration of different ways of mutilation ... then "Oh! He can't possibly be like his mother. She had a very high standards for Her friends. Maybe his stepparents taught him this indiscrimination of friends."

"She was shallow"

"SHE was shallow!? ... But She married that brat Potter. Was Her standards high after all? Maybe not. And I gave all the power I could have for her..."

So I think Snape became misogynous. Thus Alissa's affection became irritating for him. I don't know what implications it will have for storyline however.

Edit: Analysis is done by Type 1 processing with Type 2 postselection, so no justification is given. :)

Edit: This hypothesis seems to be insufficient for explanation of emphasis on "wrong" in Aftermath 2, maybe there's something more.

Edit:

  1. "Wrong" can mean, that she was aware, that Snape isn't kind of person young woman is supposed to crush on. I'm not sure that this is true for Slytherin. Anyway Snape isn't handsome guy, it's not deserve emphasis to hint that.

  2. "Wrong" can mean, that she feels it's bad for her to show affection now. Fits my hypothesis, but not wording "There was probably something really wrong with her...", which imply that she knew it all the way.

Some part of puzzle seems to be missing.

The "wrong" is presumably that the wizarding world isn't much familiar with, or accepting of, urges tending towards BDSM. A student of her age would be unlikely to be familiar with the idea of such a thing not being "wrong", given their lack of internet access. ;-)

It seems like both you and Gabriel (below) have constructed hypotheses which make sense in isolation from certain relevant facts. In particular, there's a large fraction of the HP fanfic world consisting of females who write things with BDSM aspects and a dominant professor Snape. For example a dominant Snape with submissive Hermione pairing is not uncommon. Presumably whatever is going on here is in part making fun of that segment of fandom.

(I dated a girl at one point who's very much involved in the HP fanfic community and might not have picked up on this point otherwise. )

If not for Eliezer's remarks that there was something serious in this section I'd think that that was all that was going on this section- just a Take-That! to the fanbase. Given Eliezer's remarks I think he intended it to be both a Take That and also something else possibly along the lines of Alicorn's hypothesis.

Ahh, gotcha. And from what I can tell Harry would want to get results in both worlds. In fact, he would quickly begin to consider this world to be 'his'. It is similar to the kind of thinking he did when tranfiguring. From cognitive maps through molecules and atoms down to quantum configuration space. Just another step further. I would expect him to consider you and I with exactly the same priority as similar individuals that share his fictional emulation.

Now, as for what he can do to influence our world... that's an interesting thought. Create a superintelligence and solve the AI Box problem with the added difficulty of having to explain to the outside world how to build the AI structure. It is not inconceivable (but still unlikely) that the 'author' or emulator does not, in fact, know how to build a superintelligence himself. It is possible to be able to create a fictional world with someone like Harry in it while naturally being an inferior (but faster) thinker.

Say Harry found out that he was living in fiction and in the process of updating raises the probability that he can achieve godhood in his fictional universe but assigns a far lower chance to significantly influencing the base world. Would Harry be pleased or displeased by this discovery? My guess: He'd be all distraught and angsty about it. But I think that is due to him having immature emotional responses. He is, I suggest, strictly better off in the newly discovered situation than in his original scheme.

I think the problem is a lack of detail. Harry isn't being simulated down to the neuronal level, or even down to the brain region. 'He' is a loose set of rules and free-floating ideas that please Eliezer or survived his theories, a very small entity indeed. And the rest of his world is even more impoverished - the rest of the world may just be a few words like 'the rest of the world'. Harry can't even execute bounded loops unless Eliezer feels like formulating them and actually executing them.

If Harry discovered he were in fiction, his motivation to help the rest of the world would instantly vanish. In fact, the most moral thing he could do is to hide in his trunk forever - if a rape only happens when you go to rescue the rapee and the narration follows you, if the murders only happen because you went looking for murders, then out of sight, out of mind, out of reality. In a 'real' simulation, this would not be the case, even if the author would never permit a character to test this.

(He might still want to escape into our world if the author desires him to desire this, but help his world? His world can no more be helped than J.K Rowling can help Zanzibar in canon HP. There is no there there.)

I would take Rick Cook's approach - look for meta-spells and figure out how to combine them into something Turing-complete. From canon, we already know that spells can operate on spells ('priori incantatem' or something like that), and I'm almost sure that some spells do logical operations.

If that doesn't work out, start making the Philosopher's Stone. I will know that it's possible, and that's half the battle. Once I have the Stone, then the question of 'fastest method to omnipotence' loses its urgency.

(If this is simply not possible for a 1st Year, then I will set my sights lower on the felix/luck potion; Harry has enough money to finance all the ingredients he could possibly waste, and once you have a vat of luck potion, you can spend it on research in the library, random generation of possible recipes, or direct attempts at creating the Stone.)

That's already taken care of; if it's luckier to discover a luckier luck potion than the Philosopher's Stone, then that's what I would discover. And of course, by induction, then subsequent consumption will result in even luckier potions (since luck presumably compounds so any subsequent improvements will still be luckier than a PS's discovery).

If there is no luckier potion or the Luckularity would hit a plateau, then I would be better off with the PS and hence the luck and preference would line up. So seeking the PS is the dominant strategy.

I would look into magic detection spells and see what I could find out about magic from them-- not just studying the spells themselves, but also see if there are subtle things about magic (does it come from somewhere, how fast does it happen) which offer clues about its nature.

Also, can magic be used to increase magic? Follow that with careful thought about the implications of a magical singularity.

Pretty much what he's trying to do: Figure out what magic is and how it fits with the rest of reality. That understanding is bound to bring up a few shortcuts to ultimate power.

There's been some speculation on what a +4 spoon would do, so I figured I'd weigh in as an expert of sorts on D&D.

Really, it depends upon what it's being enchanted for. I think the default assumption is that it's enchanted as a melee weapon, and so functions as a diminutive one-handed weapon that does 1d2+4 damage - given the strength of such creatures, you're probably looking at 1d2 damage after the strength penalty, which is a modest improvement over the 1d2-4 (minimum 1) an unenchanted spoon would get you, for the reasonable price of 32,300 gold pieces.

For justification of this, that effectively makes it a diminutive club (d6 stepped down 3 times); it would be capable of being wielded as a light bludgeoning weapon by a tiny creature (something about cat-sized) at a -2 penalty, and not effectively usable as a weapon by anyone small (halfling-sized) or bigger.

An alternate explanation would make it a spoon which gives you a +4 bonus of some sort to a spoon-related skill, which would then be about 4000 gp (twice normal for not taking up an equipment slot).

It gives a +4 bonus to the dexterity check to avoid dropping ice cream on your clothes, or others' clothes. However, due to a quantization issue in the laws of physics, exactly one-twentieth of all scoops still result in critical failures, and many of those failures lead to food fights, which is where the +4 to hit and damage comes in.

Does a dex check have a critical failure on a 1? I think that applies only to saves and attack rolls. Skill checks don't suffer that problem and I think the same rule applies to flat ability checks. (I'm going off the 3.5 rules here, I seem to remember when critical failures occur was slightly different in 3.0 which may be relevant here)

From reading it, I got a sense that Eliezer actually has something in mind on how magic works in the story. That would be mindblowing because it would have to be a consistent explanation how magic works, how magicians got to use it, why they loose power over time. And why no physicists stumbled over it by accident.

Is that a shared idea, or am I the only one?

There's a fairly obvious answer to that stuff in my opinion. Ventus by Schroeder (scifi) covers it nicely. It would be a structure set up by the atlantians for control of nature, before they ascended probably and left Earth for the stars.

Edit: It occurs to me that the other possibility would be a simulation, originally invented by the atlantians for them to upload themselves into, or perhaps muggles were supposed to be NPCs.

See Larry Niven's "The Magic Goes Away" universe. He does not seem to have worked out "particle physics with magic" to explain how to cast spells exactly, but he does have a universe that makes more logical sense in terms of economics and sociology and so on.

Basically all atoms in his universe had an aura of mana which functioned as a non-renewable source of "magical energy" for "everything magical you've ever heard about". Some magic can also be gimmicked out of events with emotional resonance to recharge nearby atoms but not very much, and most really huge emotions happen because of personal loss, so there is still an implicit sort of "third law of magic dynamics" at work relative to any magic that's worth acquiring.

The reason physicists haven't discovered it is that there's basically none left.

So far many chapters managed to up the ante. Meaning there is way more depth than i expected initially. The story wouldnt loose much if there is no magic explanation, but well. it would be mind blowing if there is. And of course Harry will research till he hits the solution or a dead end.

I made up a few trivial sounding solutions for all the patterns shown in the story (trivial for LW/OB readers) but do not want to invite too much speculation.

Another thing I really liked was the depth of characterization. Usually in SF thats not too well done. Here the nice old teacher lady, Dumbledore, Harry, Hermione and so on all appear as full characters with strengths, weaknesses, insecurities and motivation.

Looking forward for the next chapters!

Reading through MoR, I made a point of reading the reviews and seeing what non-LW people were saying.

Harry Potter fanfiction and its readers is way closer to mainstream culture than the sort of people who could read that crossover fic; keep in mind, Harry Potter fanfiction novels have been published as have entire books just predicting what would happen in book 7 or comprising dictionaries of Harry Potter-ania (you may remember the lawsuit over the latter).

Chapter 21

Draco's choice of subject. Expected, but unfortunate. It would be fun to know the physics of the magical universe. The biology is not completely exempt from the physics, of course. Also, there can be many fun incidents introduced when they are trying to sample people. Imagine trying to get a skin sample from albus dumbledore, the most powerful wizard around or trying to figure out why Aberforth wasn't that great.

The Dark Mark - They would have thought about it. My guess is the dark mark came around only after a certain power threshold was already crossed and the death eaters were able to ahem... signal freely.

Speculations on Santa Claus

Sirius - Most probable. Sounds like him, sounds like Pettigrew is dead from information in the train station chapter. Sirius is out of azkaban or is remote controlling someone (kreacher?) really well.

Nicholas Flamel - Well, his name is Nicholas :-) and he is knowledgeable enough to create a philosopher's stone and is brave enough to cross over to the threshold of death without worrying much. (In the HP universe, death is not final. It is kind of a change of state, like uploading. ) So, he could have been curious enough to examine the cloak, while having a reputation strong enough that james would give it to him. He also knows Dumbledore's weakness as a holy grail seeker, sorry, seeker of the deathly hallows.

Albus Dumbledore - Also very probable. And giving away partial information is also a good tactic to give the impression that it is someone else.

Lupin - For all the reasons similar to sirius, but not rich enough to give away money.

What evidence exists for an afterlife in the HP universe? I haven't actually read the novels beyond 1-3, just fanfiction, and movies 4-6.

EDIT: Since people have asked why:

I read books 1-3 while I was still living in Chicago, and the whole family read them together. Then I moved out in 2000, and didn't get around to trying to read book 4 until it was time to write the fic... and found that I couldn't seem to read it. Maybe it was a change in the literary quality (I've heard others say that) or it was the fact that I'd already watched the movie and that got rid of the plot tension. Or (my personal suspicion) the fact that I'd read a lot of fanfiction aimed at a more grownup audience meant that the children's-book version of the Potterverse just didn't feel right to me any more.

I feel guilty about not reading the later books, obviously, but my brain doesn't want to do it and one of the major points of this whole endeavor is that it's fun, not something I have to make myself do. So I've been getting along on movies 4-6, other fanfiction, and above all the Harry Potter Wikia.

Mentioning this because TV Tropes is now giving me a "Did Not Do The Research" trope, which is supposed to be for people who didn't care enough to find out something they could've gotten in 10 minutes, and that stings a bit. I tried, I really did, and now I read the Wikia and try my best to get things right, but I'm just not enjoying the original Potter novels. Not every children's book, even ones that have taught millions of children to enjoy reading, ends up being enjoyable to every adult.

"Harry Potter and the Methods of Rationality" is in the Potterverse because I was attracted to the universe of Harry Potter fanfiction.

I'm aware that people have tried to interpret it that way. I'm also very sure that that's not at all what Rowling intended. It simply doesn't fit with her general approach in the books.

The heroism objection is that there's such a large deal made about Harry's willingness to sacrifice himself. But he's just found out that there's a happy afterlife where he'll get to be with his parents and everyone else who died in the books. Given that, the sacrifice is much less impressive.

It's been a while since I've read the books, so forgive me if I'm missing something. But I thought Harry wasn't sure if there was an afterlife. He even expresses doubt whether the "afterlife" conversation is something he's just imagining in his head.

Also, I think that argument proves too much: it would apply to every soldier, terrorist, freedom fighter, activist, and martyr who believes in an afterlife.

True, but Harry's certainty in an afterlife is much higher than that of any of those people, and his certainty about the nature of the afterlife is also much higher. Moreover, he's been specifically told that death isn't a big deal. Fvevhf says that it is a smooth transition.

"Found out that there's a happy afterlife"? You're reading a lot more into that scene than I did. My interpretation of it was that he had a near death experience, and like lots of other people having such experiences, he hallucinated something about an afterlife, with no reason to believe it was anything more than a hallucination; fortunately he was sane enough not to take it too seriously. He certainly did not subsequently behave like he had suddenly started placing much less value on life.

Are we talking about the same scenes? Harry gets a hold of the Resurrection Stone and talks to his dead friends and relatives before the encounter with Volemort where he lets Voldemort kill him.

Another reason to read the other books, you are occasionally making minor contradictions with her magic system that wouldn't occur if you read the other books.

You said it correctly here, CronoDAS. That is the exact meaning I wanted to convey - the transition is irreversible, but there is some sort of existence.

To be fair, in SW, the Force ghosts never do anything particularly powerful. (Even in the EU, the most powerful Force ghosts, like Exar Kun, usually must act through agents.) If Obi-Wan's statement is anything more than rhetoric (and it's never safe to just rule out 'it's rhetorical/symbolic'), it's a reference to Luke, who at least in the EU is basically the most powerful Force-user ever.

Up to chapter 31 now. I don't understand how Eliezer is going to paint the central conflict. Granted, Quirrell is awesome and has had several successes already. But the main motivation of the Death Eaters is blood purism (as in canon), and Harry has already proved it to be false, and our Quirrell is rational enough to agree with the proof if he hears it. So to make the central conflict happen Eliezer has to invent something else, something secret, that makes Quirrell tick.

I think he may have already done so, by way of Quirrelmort's reaction to Harry's statement that he wanted to use science.

Voldemort is scared of muggles. Quite reasonably so; despite Harry, there are enough of them that they'd very likely overtake the magic-users in a matter of decades on all useful fronts, and even now a conflict between muggles could squash the wizards like a bug.

Basically, I think he wants to

(a) Strengthen magical society to the point where they can stand up to the muggles. Harry might be helpful here, but there's a good chance their plans would conflict. Failing that..

(b) Get the hell off this rock.

It appears that a very large number of wizards are blood purists; Quirrel might just want power, and think that the best way to achieve that is by stirring up hatred for mudbloods.

You can have a third party create a cryptographically signed timestamp for you. For example, secure-timestamp.org will do this. This can only be falsified by getting the timestamping server's private key or breaking its crypto algorithm. For things more important than Harry Potter predictions, you can have multiple third parties timestamp them for you, in which case falsification requires stealing all of their private keys.

If I assign p=.99 to an outcome and the outcome turns out to be false, it is a good bet that I misunderstood the question or misunderstood some proximate cause of the outcome, and in this case, the proximate cause I am most likely to misunderstand has to do with properties of hash functions.

I think you're confusing separate issues. The idea of having contests where two mathematicians would each issue challenge problems to the other was primarily an event in the Middle Ages. This idea then continued in some forms with people like Fermat (later Middle Ages or early Renaissance depending on how you define things) who would issue challenges to others to prove what they had already proven. What Orthonormal is doing actually more closely resembles a practice from the 19th century where when multiple people were racing to solve a problem first, they'd every so often deposit a sealed envelope with some reputable independent body to verify issues of priority.

You're right, I was confused on the dates.

Then, if someone else discovered the same thing, they would say "aha, but here's my discovery" and point out how they came up with it ten years earlier by giving the "unhashed" version.

Chapters 25 & 26

Quirrell is cold. It looks like he gave Rita Skeeter a tip that something would be happening in Mary's Room so that she'd go there as a beetle and he could (literally) crush her. Is Harry going to start to figure him out (like he did with Draco after his reaction to that other newspaper headline)?

Also, does anyone know if Q/V's habit of whistling/humming a tune (appearing in both chp. 25 & 26) is based on something in canon? It sounds like a tell, when his plotting against Skeeter/Potter is going according to plan, but I'm wondering if there's anything more to it.

One more thought, this time money related stuff:

On the one hand, the magical and muggle economies are sufficiently separated that Gringots seems to not even notice the possibility of arbitrage...

But on the other hand, we're told that anyone who transfigures stuff to look like money, even muggle currency, is legally at war with the goblins. If the goblins are tracking muggle money enough to at least notice this sort of thing and care about it, that seems at odds with them being sufficiently ignorant of the muggle economy to not notice the arbitrage possibilities.

The goblins may only use that to check for Muggle currency that wizards try to turn in to the goblins. They may also have methods that just track objects transfigured to look like Muggle money. If goblins have similar cognitive flaws as humans, then they might be able to keep track of the economy for this one very specific purpose and not even realize that arbitrage was really a useful practice.

You could avoid selling Galleons per se by melting them into bullion first. Maybe Galleons are unmeltable? Or the gold turns into leaves and gorse blossoms when handled extensively by Muggles?

No, that wouldn't work. In MoR, the routineness of coining Sickles implies that it's routine to coin ordinary gold into Galleons; if the coinage were irreversible, then you would see Gresham's law start to operate.

Ordinary gold would be more valuable then an equivalent weight of Galleons because you could at any time turn the gold into Galleons but with ordinary gold you have all the other decorative and magical uses of gold available. As Galleons are created and not destroyed, ever more inflation of Galleons and deflation of gold would happen.

(Have you ever bought funny money, like the Mickey Mouse money at Disney World? The Galleons would be like the Mickey Mouse money, and gold like regular dollars. Except worse.)

Chapter 33:

I'd come up, before, with the hypothesis that HPMoR Voldemort was actually Necessarily Evil after the fashion of Eliezer's proposed supervillain gambit, but I dismissed it by assuming that Voldemort had crossed the Moral Event Horizon already. This chapter, though, makes it very plausible again via an explicit motivation (and a Shout Out to Foundation, as well). On the other hand, Quirrell could just be playing one level above that explanation.

One thing, though: is it public knowledge that Lucius Malfoy had been a Death Eater? Because it seemed to be a very dangerous thing to say out loud (not that Quirrell need fear Lucius, but that it seems foolhardy to so easily signal that he need not fear him).

Is Harry learning how to lose?

Chp 19 is when Harry went through the ordeal with Quirrell to learn how to lose.

Chp 21 he lost the textbook reading contest with Hermione and acted like a whiny sore loser, suggesting that he hadn't really learned much. He acted like such a brat that I had to assume that he'd failed to learn some basic social skills in his solitary homeschooled childhood (e.g., you should at least act like you've lost gracefully, by congratulating the winner and not complaining).

Chp 32 Harry seems to be trying to goad Draco and Hermione into cooperating with each against him in the battle, suggesting that he hopes that they work together to defeat him in the game, for the greater good (of Draco's character and their relationships). It can't happen, because the state of the game demands that Draco cooperate with Harry rather than Hermione in order to have a chance to win, but if Harry was considering it and hoping for it then that's a good sign for his learning.

Chp 33 provides more support for this take on chp 32. Draco & Hermione threaten to cooperate against Harry if he accepts traitors, Harry openly proclaims that he'll accept traitors and challenges them to cooperate, and Quirrell is surprised by Harry's response. This makes the most sense if Harry is thinking outside the game and seeing his tactic as win-win: either he gets Draco & Hermione to cooperate (win in life), or they fail to cooperate and he has an advantage in the battle (win in the game).

Another point in chapter 32 that could use some explaining: Why are Harry, Draco, Hermione the only ones in the running for the Christmas wish? Do Quirrell points from battles tend heavily towards the generals? (Though I guess they were all doing especially well in the class anyway...)

Harry's knuckles had gone white on his wand by the time he stopped trying to Transfigure the air in front of his wand into a paperclip. It wouldn't have been safe to Transfigure the paperclip into gas, of course, but Harry didn't see any reason why it would be unsafe the other way around. It just wasn't supposed to be possible. But why not? Air was as real a substance as anything else...

Well, maybe that limitation did make sense. Air was disorganized, all the molecules constantly changing their relation to each other. Maybe you couldn't impose a new form on substance unless the substance was staying still long enough for you to master it, even though the atoms in solids were also constantly vibrating all the time...

The more Harry failed, the colder he felt, the clearer everything seemed to become.

The cold feeling should have given him an idea! He has a spell for lowering temperature. Unless it is, for example, helium a gas with sufficiently low temperature tends to prefer to go by the name 'solid' (Depending on cooling speed probably isolating one specific component of air). That gives him a two step process for transfiguring gas into paperclips.

Mind you, Harry most likely doesn't have the magical ability right now to lower temperature that effectively. Perhaps that's where Hermione's idea to actually practice magic comes into play!


Instant godhood by inventing nano-tech? That doesn't seem to leave much scope for names for all the levels of power that are far ahead of mere non-replicating nano. Perhaps demi-god? Even that seems to be overstating things. It seems to be on a par with the potential of the most advanced magic applied intelligently but without Harry's munchkin mentality.

A thought regarding Alzheimer's cures: If you are playing around with creating an Alzheimer''s cure with transfiguration and find yourself thinking more clearly all of a sudden be very afraid. You have probably absorbed some of the transfigured substance. Most chemical cures for Alzheimer's will also improve abstract and creative thought in healthy humans.

Time-travel makes certain laws of physics uncomputable, but there are any number of equivalent, far more complex sets of laws that would look the same to humans but remain computable - Eliezer's mind is running one, for starters. When writing a simulation, you would use one of those.

Chapter 23: I wonder when Harry will realize that the reason he's an idiot isn't that he doesn't have a perfect emergency kit (though that's important), it's that he doesn't have a gut level understanding that the wizarding world is very dangerous, especially the Malfoys.

I was just thinking along these lines again when I read the July 2 update.

Chapter 15:

"You needn't apologize, Mr. Potter, if you were required to read ahead you would have been told to do so." McGonagall's fingers rapped the desk in front of her. "Mr. Potter, would you care to guess whether this is a desk which I briefly Transfigured into a pig, or if it began as a pig and I briefly removed the Transfiguration? If you had read the first chapter of your textbook, you would know."

Harry's eyebrows furrowed slightly. "I'd guess it'd be easier to start with a pig, since if it started as a desk, it might not know how to stand up."

Professor McGonagall shook her head. "No fault to you, Mr. Potter, but the correct answer is that in Transfiguration class you do not care to guess. Wrong answers will be graded with extreme severity, questions left blank will be graded with great leniency. You must learn to know what you do not know. If I ask you any question, no matter how obvious or basic, and you answer 'I'm not sure', I will not hold it against you and anyone who laughs will lose House points. Can you tell me why this rule exists, Mr. Potter?"

Because a single error in Transfiguration can be incredibly dangerous. "No."

"Correct. Transfiguration is more dangerous than Apparition, which is not taught until your sixth year. Unfortunately, Transfiguration must be learned and practiced at a young age in order to maximize your adult ability. So this is a dangerous subject, and you should be quite scared of making any mistakes, because none of my students have ever been permanently injured and I will be extremely put out if you are the first class to spoil my record."

Chapter 26:

"Professor Quirrell," said Harry gravely, "all the Muggle-raised students in Hogwarts need a safety lecture in which they are told the things so ridiculously obvious that no wizardborn would ever think to mention them. Don't cast curses if you don't know what they do, if you discover something dangerous don't tell the world about it, don't brew high-level potions without supervision in a bathroom, the reason why there are underage magic laws, all the basics."

Chapter 28:

Earlier, Harry had very secretly - he hadn't even told Hermione - tried to Transfigure nanotechnology a la Eric Drexler. (He'd tried to produce a desktop nanofactory, of course, not tiny self-replicating assemblers, Harry wasn't insane.) It would have been godhood in a single shot if it'd worked.

In our world, there are various weapons that could be used to kill at least as many people as a nuclear bomb would. GE plague is one, and it's easy to believe that in the near future a competent biologist would be able to engineer a usable bioweapon at home. With that alternative in mind, I would love for GE bioweapons to only be accessible to super-rich biologists.

There are fewer super-rich physicists than there are ordinarily rich states who possess nuclear weapons. Plus, 90% of the actual use nuclear weapons get is deterrence, and secret nuclear weapons are useless for that. OTOH, for garage-based first strike capacity nuclear weapons aren't required, there are also bioweapons etc. That's why I'd rather the physicists had a monopoly.

Probably no-one. And today no-one really holds nations with nuclear capabilities accountable. How are physicists any worse?

Consider that physicists have fewer potential reasons to use nuclear weapons than do nations, or to go to "war" with one another. If they attacked one another, or third parties, they would not be able to protect themselves from (non-nuclear) retaliation as rulers of nations do, because they wouldn't have large territories and conventional armies. If they won the war, they wouldn't get any economical benefits; their only possible reason for using the nuclear weapons would be to kill some people. I consider that individual people, particularly those who are well-off and have a lot of money to solve problems with, are much less likely to want to kill others than are nations.

From Ch. 7:

Draco snarled. "She has some sort of perverse obsession about the Malfoys, too, and her father is politically opposed to us so he prints every word. As soon as I'm old enough to get an erection I'm going to rape that bitch."

Is this a reference to some poorly-written slash fanfic? I'm assuming Eliezer knows that boys of any age can get erections, so it must be making fun of something, but I'm missing a reference.

Similarly with:

Harry burbled on. "I'm delighted to meet you, Mr. Malfoy. Just unutterably delighted. And to be attending Hogwarts in your very year! It makes my heart swoon." Oops. That last part might have sounded a little odd, like he was hitting on Draco or something.

Alternatively, male sexual development might be more varied than is commonly believed.

Or the Malfoys might put a lock on their kids' early sexuality to make them easier to control. Something like that might make arranged marriages less prone to drama.

I think this might actually be feasible. Malfoys are probably not likely to have intimate enough conversations with children from other families that something odd is going on, and could write off what other children imply as just big talk.

Or the children could find out the truth relatively early, and buy into a family belief that this is the sensible way to do things rather than an imposition.

It is expected that villains, even in the canon of children's books, will kill and maybe occasionally torture victims in order to establish that they are bad. It is not expected that villains, especially in the canon of children's books, will permit/condone/commit rape. Additionally, the sorts of emotions that are commonly supposed to precede murder and torture are more familiar than the sorts of emotions that are commonly supposed to precede rape, and so someone unfamiliar with the actual etiology of any of those crimes finds rape less relatable and more shocking.

Agreed. I also think the original "Which of these characters has crossed the moral event horizon?" question (in one of the Author's Notes) was a little bit misguided because, as far as most HP readers are concerned, Voldemort is already considered to have passed the moral event horizon from the outset. There's little he could do that would make us think "Wow, I didn't know Voldemort was that evil". And 11-year-old Draco, being the son of a Death Eater, might be expected to hold certain evils as justifiable or compulsory — we expect that he's been conditioned to find it acceptable to kill, torture, and exploit non-purebloods, and generally to manipulate people for his own ends. And as long as he's still young, we're inclined to be relatively lenient in judging him for those attitudes, considering he has never learned anything else, nor been allowed (or allowed himself) to reconsider it. What we don't expect is for him to talk casually about committing rape, considering that nobody in the series does, even the darkest of the canon dark wizards; it makes it seem like it's an idea he came up with on his own, like he just heard a definition of rape and thought to himself "Hey, that sounds like a fun thing to do to young female political enemies, and I bet I could get away with it, too". So I bet most of the objections were based not on thinking "that's more evil than Voldemort", but "that's way more evil than Draco is supposed to be right now".

Right, this evidence is one of the strong pieces of evidence that undermines the entire rape-is-about-power claim. And there's other evidence for this also (for example, prison systems that allow conjugal visits have lower rape rates than those that don't(a citation for this claim would be nice. I've seen it before but a quick Google search doesn't turn up anything useful)). But sometimes, it is about power. Indeed, the type of rape being discussed in this context, by someone like Draco is the classic power situation. And when people are raping enemies that's more or less unambiguously about power.

My impression of approximate rape statistics was along the lines of 90%/9%/1% male->female/male->male/female->male. I don't know where female->female fits.

"Involuntary heterosexual coitus" is the last think of when evaluating the relative expectations of pain.

Wikipedia on motivations for rape

I think it's complicated. Even the access to the internet lowering the incidence of rape could be about increased chances of finding partners as well as access to more porn-- it isn't as though porn was rare before the internet.

My impression is that it isn't as true as it used to be that fictional evil characters are ugly, but I don't have stats. It's certainly reassuring to think that the people you find repulsive are also more dangerous.

If I recall correctly, she was attractive-- even beautiful-- in the books until she was imprisoned, at which point she became a shadow of her former self. However, she was imprisoned for torturing two people into insanity (I can rot13 that if necessary, but I think it's a very minor spoiler at best), so I think it's fair to say that she was evil before she became unattractive and not the other way around.

Ceteris paribus, girls are far, far less desperate than guys. Supply and demand says an egg produced once a month will have a higher asking price than what guys churn out. This makes me suspect female rapists must be less attractive.

There may be different factors going on for female rapists. The statistics you cite don't separate out male and female rapists, and I suspect that female rapists are less likely to rape out of desperation, rather than being less attractive.

Those are the children's books version, and MoR is not a children's book, nor is most fanfiction. If you'll pardon the size of the hypothetical: If the Death Eaters actually existed, no way in hell are the males not committing rape.

I agree. My point was only that, in the context of the canon, having an 11-year-old boy talk about committing rape seems more jarringly unexpectednarratively, not inferentially — than having him talk about committing torture and murder (or having an adult Death Eater commit or talk about committing rape), relating to my point that the "Which of these characters has crossed the moral event horizon?" question was probably not relevant to people's actual objections.

(For the record, I'm not arguing the line shouldn't be there, and I don't disagree at all with your rationale for including it. I'm just trying to imagine the thinking of people who did react negatively to it.)

Still, while blood purism is an obviously easy win for the author, it strikes me as pretty well built into human nature to have a destructive political movement based on amping up prejudice. What would you consider to be a more universal basis for evil?

I have to say, for a blog (?) focused on good writing and story structure, that's a really terrible essay/brain-dump - highly repetitive, problems mostly alluded to rather than described, fact & citation-free, and very very ranty. (I suspect I'd also find a number of self-contradictions if I cared to re-read.)

If it didn't have the occasional good insight, I'd never have finished reading it. I did, but I still hate essays which are intermittent reinforcement schedules.

But here's one good point. By the end, the real sin of Voldemort is not being evil, but in seeking to avoid death. Rowling implicitly seems to be saying: 1) you can't live forever 2) you shouldn't avoid death 3) death is good.

LWers may grudgingly accept #1 ('fine, I can't live for ∞ but can't I live for a few thousand years at least?'), but I think we all pretty much vociferously disagree with #2 & 3. And if we were put into the Potterverse, I think we would pretty quickly all go over to the Dark side.

And that observation suddenly changes my interest in MoR from 'what is Quirrelmort's grand plan?' to 'how does Harry rewrite Good & Evil and fix that sordid little world?'

Thanks. I'd been wondering why I was having trouble focusing on the essay, and thinking the problem might be me.

I kept reading it because I thought a lot of the zip in the series faded out in the later books, I hated the epilogue with a passion, and was hoping that I'd get some explanations for why. I think I got some partial explanations, though I got tired of the theories about what Rowling must have been thinking.

Also, at the point when I'd mentioned the essay, I hadn't gotten to the material about accepting death nor the revolting chunk of resentment about how Rowling cheated to make her books popular by not concealing that she's pretty.

"Accept death" is a cheap and easy way to add profundity to fantasy and science fiction. I think the anti-immortality stories are pretty much sour grapes, and there are a lot of those stories. Peter Beagle's built a big chunk of his career on them.

Rebecca Ore's Centuries Ago and Very Fast is an exception-- the main character is non-aging and a time traveler, he likes his life, and he has a pragmatic ability to enjoy it.

If you want to see it done right, in a way that completely revolutionizes your interpretation of the source material and gives you genuine insight, resolving all sorts of continuity issues, plot holes and whatnot, proving its case with citations and points beyond a reasonable doubt, the beau ideal would have to be The Secret History of Star Wars.

The short answer is that A New Hope had nothing whatsoever to do with any grand story about Darth Vader, who was merely a mid-level flunky of the Empire. Empire Strikes Back and Return of the Jedi frantically retcon this, but Lucas simply didn't have a decent backstory centered around Darth Vader and couldn't come up with one.

The longer answer goes into the above, and also points out that Lucas's support network (of beta readers, if you will) which edited and improved his trilogy had largely fragmented or vanished by this point. For example, his wife, a very skilled film editor, had divorced him by the time of the prequels.

Death is an extremely important theme throughout all seven books. I would say possibly the most important theme. If you are writing about Evil, which I am, and if you are writing about someone who is essentially a psychopath, you have a duty to show the real evil of taking human life.

No, because the books heavily imply that Voldemort didn't believe. He was not pure-blood himself (Adolf Hitler, incidentally, was a very bad example of the Aryan ideal). And, I think that the discussions of how Voldemort chose to interpret the prophecy as referring not to Neville (as pureblood as they come) but to Harry (who, through his mudblood mother, is impure) specifically take this tack.

Interesting. My recollection was that as the books progressed, the plausibility of LV not caring about pure-bloodedness grew larger, but he himself didn't admit to any such thing onscreen. Then in Deathly Hallows he suddenly did care about it again, because Rowling suddenly realised that he didn't actually have a motive at all. So any old ill-fitting one would have to do, as part of the overall trainwreck.

Only twice here, but I have a good memory for written material, and the ideology, physics, and philosophy of Harry Potter interested me long before MoR - so this is just an old topic for me.

Do you think the Death Eaters really care about Pure Bloodism?

Some do. The Blacks and Malfoys, probably. Others are in it to 'back the strong horse', and others are in it because it gives scope to their sadism.

Is MOR's Draco being shocked to find out that Pure Bloodism isn't true just a sign that he's young and naive?

Yes. Eliezer has written about 'nonoverlapping magisteria' before: they are transparent efforts to shrink religion to something which can't be falsified, an effort at special pleading. Even though religion (especially Western ones) have made many empirically falsifiable claims - which largely have been falsified. A very young person might take those claims seriously and be shocked that they are falsified.

To not know theological explanations of the theodicy (a topic recently relevant because I finally got around to reading Eliezer's Haruhi story (which was very good)), to not 'believe in belief', to not dismiss empiricism, to lack all those sophisticated dodges and excuses that intelligent adult theists use to remain theist - this we call 'young and naive'.

(Think back - do you recall any good arguments made against pure blood, the theory as opposed to the believers? Rowling assumes we'll instantly identify pure bloodism == racism, and that's that. If they think any harder, most people will fall into the usual trap of thinking that exceptions/brilliant-mudbloods like Hermione Granger disprove pure bloodism, which of course they don't. The history of the Wizarding world is even more consistent with pure bloodism than not!)

Additionally, the sorts of emotions that are commonly supposed to precede murder and torture are more familiar than the sorts of emotions that are commonly supposed to precede rape, and so someone unfamiliar with the actual etiology of any of those crimes finds rape less relatable and more shocking.

It seems to me that people think rape is preceded by sickness, as in "he must be a real sick bastard".

I have a notion that this bit (especially the earlier version where Draco admits to not having erections yet) was the result of story constraints.

After somewhat about the Malfoys being pretty cool in ways which are important from the point of view of the story, it was necessary to shockingly remind the reader that they're also morally deficient and seriously bad news. At the same time, it was also a good idea to make this a hypothetical threat-- the story line isn't now (and perhaps not ever) about Hermione being in danger.

Read chapter 22 and 23, then look at what you just wrote. Are you sure that's the same Draco? If the passage actually does need more shock value (and I'm not quite sure that it does, especially given the wide variance in reader taste and the number who enjoyed the rest of the fic but thought that one part was too shocking) then it has to be more in-character for the later-revealed Draco. There's a simple way to increase the shock without adding vulgarities that polite young Death Eaters don't use - namely, substitute "torture and rape" for "rape" - but I already think this whole conversation is getting a bit off-topic for LW.

And that's just the sorts of images I like. There's also the role playing I do in Second Life. I do stuff that's only possible in a virtual reality. Morphing my body into whatever form I happen to find convenient, creating and manipulating virtual objects in ways I find useful, and of course defying the conventions of our universe's physics. And sometimes even directly manipulating my mental state, or doing stuff like telepathically sending out waves of pleasure and happiness.

And then there's books... My favourite transhuman sex scenes are from Greg Egan's novels. He did a good job of thinking of some genuinely original ways for transhumans to have sex. Most notably in Shild's Ladder, with the aliens whose genitals form new and interesting shapes by exchanging pheremones with their partner. And also Oceanic, which featured the "bridge", which allowed the inhabitants of the planet to swap genders with their partner after they have sex. And then there's the 7-gendered society in the novel Distress. And one brief scene of virtual reality sex in Permutation City, and also a couple of his other short stories... hehe, sex positions that are only possible in 4 spatial dimensions :)

I didn't like Prime Intellect though, it involved way too much pain. Actually, when I read those scenes, I imagined what they would be like if the people modified their minds to experience pain as a new form of pleasure. That... was interesting :)

It's one thing if someone reads Chapter 7 well enough, before and after, to spot the other change I made to Draco; but having a little automatic computer notifier makes my life more nervous.

You mean the removal of "there's plenty of girls out there who deserve it", or some other change you made in the past?

And why is the auto-scanner anything but good for anyone? Had I not had it running, I would never have become at all aware of the changes, and the old version would have remained the only one I knew.

Also, what kind of load does Update Scanner put on FFN's servers?

I read it as a teenager and didn't love it. Many things annoyed me, but most of all the insanity of training Ender and company exclusively in skills other than the ones they would actually use (people floating in space with hand-held lasers) rather than the skills they needed. Also the absence of anything that looked AT ALL like a bell curve distribution of ability. The battle school kids are all supposed to be massively well selected and trained, yet only Ender, Bean, Valentine and Peter really matter. The battle school kids in general are all an absurd backdrop just to train "the one" who has been identified ahead of time. Finally, overly complex plans working annoyed me a bit and extreme military/governmental competence annoyed me more.

True Names and other Dangers is a weird case of an anarcho-libertarian writing a story showing extreme military/governmental competence.

Probably a stored rant here, but the thing that put me off most from Ender's Game (which I'd read as an adult) was that the adults con a child into pushing the button which wipes out an alien race, and with the intent of absolving themselves from responsibility. IIRC, Ender actually does accept (partial?) responsibility in a later book.

Even though I've become more cynical since I read that book, I still think the adult behavior was well outside the human range. The normal thing is to blame the aliens for humans thinking it made sense to wipe them out.

comment by JenniferRM · 2010-07-11T04:36:57.873Z · score: 6 (6 votes) · LW · GW

I think its trickier than that - the adults are portrayed as being incapable of the "necessary" brilliance and/or ruthlessness. They put Ender in the hotseat because they hope he'll do "something to win" without really visualizing what that something might entail. He's simultaneously their "more powerful optimizing process" and (using LW terminology that makes me a little uncomfortable) their shabbos goy.

Its possible that the first two books were written specifically to explore the structure of moral reasoning in situations like this. How do people morally process a genocide that no specific person directly and obviously intended, especially if their theory of moral reasoning hinges primarily on intent?

I don't mean to pull a Godwin, but there may (intentionally?) be a strong set of correspondences between Ender and Hitler, with a literary goal of getting people to "identify and forgive Hitler" - that is, the whole book may be a literary "Godwin prank". I should note that this is not my original analysis, in part because I know almost nothing about "Hitler scholarship". The original insight came from Elaine Radford, I heard about it via a K5 post by a friend of hers telling the story of how Orson Scott Card freaked out and tried to bully her into not publishing the analysis after book two but before book three (which was massively delayed, possibly because of the review if you buy the K5 story). The analysis was later cited in Creating the Innocent Killer: Ender's Game, Intention, and Morality.

For reference, I read Ender's Game and really liked it when I was about 12. After my brother and I read it we tried to get our mom to read it and she stopped like 20 pages in because the horrific child abuse turned her stomach.

I stopped reading Card in my 40s or thereabouts because, while I was fascinated by the character torture, I became uncomfortable with my fascination. I'd earlier realized that there's something really creepy about a lot of the older male characters in Card-- they do horrific things which are justified in the text.

Discovering that you can no longer stand a book you used to love is sometimes called "the book was visited by the suck fairy".

If you select out the right end of the bell curve from the general population, then you won't have a bell curve anymore, but rather a fat lower end.

Also, the training was supposed to be a sort of abstract sport to select for leadership skill, coolness under pressure, etc - it wasn't supposed to be actually training them to fight in space. They did training of the actual spaceshippy stuff later. You could certainly argue they should have started that earlier though.

I read it in middle school, and, though I know there's a tendency to see my earlier self as having the benefit of hindsight, I swear that while I really enjoyed the cathartic nerd-violence, I also had an awareness that there was something creepy and wrong with the whole thing, even if I couldn't put my finger on it. I was both attracted to and horrified by the book. I had a faint sense that feeling that self-righteous is a very dangerous sign.

I then largely forgot about it (it seems to have strongly influenced a lot of people who read it at that age, but not me) until I reached adulthood and stumbled on criticism from Kessel and Radford, whereupon it all fell into place and I congratulated myself on having seen that there was at least something there to criticize.

You know, as I was reading chapter 32, I started thinking about how the three generals had their various weaknesses. Draco is savvy but weak against complexity, Hermione is bright but not exactly street smart, and Harry is clearly brilliant yet arrogant. It was only after I'd read it all that I realised each had fallen prey to their own specific weakness. Hermione was surprised by the combined 'For Sunshine!' Gambit against her, Draco didn't realise he was with the wrong Patil, and Harry encouraged earlier betrayal amongst his crew in order to protect him in the final battle, only to be surprised at the end. I figure this was probably a deliberate bit of writing on Eliezer's account, in which case I just want to say-Good job!

Now, chaotic fighting indeed doesn't fit with the Protoss at all. But Hermione's strategy is by far the one that most parallels a hive-mind, and for all we know the semi-sentient Zerg really are all happy-go-lucky on the inside.

Assume that Draco and Harry both value victory at $1000. Now if you demand $800 from the winner, the loser "would have" gained only $200 in the counterfactual case, so he will pay you $200 at most. So you could have just demanded $1000 minus epsilon from the winner. We could probably prove a theorem that says counterfactual mugging can't help you extract more of the surplus economic value that you create.

Edit: Ah, wait, they can't change their allegiance as targets, can they? Otherwise Zabini wouldn't be able to choose the victor at the end.

Chapter 32: Why didn't they (visibly) use change of allegiance for defense in the second phase? If you turn yourself into a soldier of the enemy, then the enemy will lose a point for shooting you. Thus, everyone should hold allegiance to the enemy except for the exact moments they fire (which would be quite hard, since you'd need to find someone with enemy's allegiance who is not loyal to your team).

So, it should've been this way:

I should really have mentioned this back in the appropriate chapter, but..

Remember how Harry complains that adding (consistent) time-travel makes the universe uncomputable? Leaving aside how I'm not exactly convinced of that myself, I thought I should point out that such consistent time-travel has recently been experimentally demonstrated.

Have a look at http://arxiv4.library.cornell.edu/abs/1005.2219 . It was published way too late for Harry to read it, unfortunately. :P

If I'm reading this right, this isn't an experimental demonstration of time travel, rather, it's a theory of time travel, the predictions of which can be determined experimentally, and an example of such an experiment, to determine what would happen in a grandfather paradox case if the theory is correct.

As I understand it, their theory is that time travel is like postselection. Hence, to determine what would happen in the case of the grandfather paradox, they set up an equivalent postselection experiment. So if their theory is correct, the results of an actual grandfather paradox experiment would match the results of this simulated-via-postselection one.

Er, I guess that answers the question I actually asked, but I still feel confused about the original situation.

At the time that the modern magical laws were set down about keeping the magical community isolated from the Muggle community, magic more or less as we know it was already in place. Why would the wizards have been sufficiently isolated from Muggles, while magic was still evolving, that not all humans now have magic? And what form of isolation would allow this kind of complex adaptation to evolve while also keeping wizards and Muggles from diverging into distinct species?

I agree with Harry's conclusions that magic must be controlled by something relatively simple on the genetic level.

Actually, I'm not sure I had a sound argument there-- I was looking for something plausible to defend my point of view.

On the other hand, I'm not sure you have a sound argument there, either.

If nothing else, how long does it take for a beneficial mutation to spread? How old is the ability to do magic? We know it was there in the during witch hunts (which had a more complex history than I thought, just like everything else), but that's probably middle ages. I don't think we know whether the ability to do magic has been around since the paleolithic.

I don't believe the canonical relationship between the wizarding world and muggles makes a lot of sense, though it works very well for stories. I believe muggles actually know a fair amount about the existence of wizards, but don't talk about it for tolerably obvious reasons.

It's plausible that wizards have less ability to cooperate (much more variation in individual powers, including the power to deceive), but it may simply be that their institutions are less complex because they have a lower population.

The scoring system is silly but at least would function. My objection is to the practical physics involved in the all the play except that involving the quaffle and the seeker. Well, perhaps the beaters are ok too, suspension of disbelief unrealistic resistance to physical trauma. But the stuff where the chasers somehow steal the ball off each other as though it is a real sport. If she spent 5 minutes thinking about her game she should have been able to do better.

  • In basketball you have to bounce the ball or be standing still.
  • In netball you can't walk at all.
  • In soccer you cannot touch the ball.
  • In ruby, etc, you are expected to physically knock the opponent over and even then you don't expect to actually get the ball off them, that is a special case. An embarrassing mistake on their part!
  • In AFL you have to bounce the ball regularly while running and not only do the opponents physically tackle you to the ground, if you are tackled you have to get rid of the ball.
  • In quidditch you get the quaffle and you can fly freely in three dimensions and have to put the ball through an enormous hoop. Oh, and there are THREE of them to aim at. There is no reason to ever pass the ball (at least as described in the books or shown in the films). The only way someone should ever not score a goal is if they are physically knocked off their broom with a bludger or via a full on aerial melee. Both of these cases would quickly result on all tactics converging to a literal "flying V". It would be the chasers that would be selected for brawn, far more so than the beaters.

Both the limited number of players, and the fact that the game takes place in 3 dimensions, make it much harder to construct a properly protected "flying V."

If there was a much higher player limit it may suggest a 'flying prolate spheroid with the quaffle somewhat closer to the back' (the latter part depends on relative broom speed. Even then I have a hunch that it will be weighted in optimal defender density somewhat towards the altitude of the quaffle bearer. This is because of the way the ball is held and the fact that the brooms will interfere with steals from below and above.

With the specified limits I suspect I would end up with defaulting to what is approximately a V but with rehearsed tactics for when one guardian must be diverted to run interference on an interceptor or gets taken out of play by good defense. It is the beaters that I would count on to cover the top and bottom, with the bottom one in particular remaining mobile for bludger defense while the top one can use the height (and gravity) advantage to quickly act as a reserve and make brutal targeted headshots.

Even 'now' the Slytherins aren't all evil. It is just that most evil came from Slytherin. I would describe Slytherin as somewhat exaggerated but otherwise realistic. People with that kind of ambitious do tend to congregate together in exclusive groups. In most cases they will not be labeled 'evil' by society. They will end up in socially powerful positions within the system. But when you have a situation where a single 'Voldemort' (or equivalent muggle) grabs for power the 'Slytherins' will quickly form up behind him. It is the sort of opportunity they are built for.

I would not expect that to happen. Not because that pragmatic drive woudn't occur to them but because tribal considerations would override it. What I would expect is for the majority of the Slytherins to quickly renounce their former position as soon as the tides of power changed (eg. if Voldemort gets his ass kicked by care-bear powers). In contrast I would expect Gryfindors to be more likely to be naive, to try to fight an already lost battle for an ideal and end up quite miserable or dead. I would expect the Hufflepuffs to be more or less irrelevant and live mediocre lives while the Ravenclaws would be too self absorbed to have all that much practical influence.

That's a good point about mutation spreading over time. MOR!Harry suggests that the magic gene might have been installed, rather than evolving naturally. In canon, we know that that Circe (presumably no later than c.700 BCE) was a witch, which is still a pretty low lower bound (2700 years) on how long magic has been around.

We also know that Wizarding exists worldwide, and that there are some cultural differences between Wizarding societies around the world. For example, carpets are more popular than brooms in Asia as a means of flying transport; the correlation with Muggle myth and folklore suggests that Magical cultures diverged over a thousand years ago. This makes it unlikely that magic was spread by European explorers; presumably there is an older (Atlantean?) magical diaspora, which may or may not have been part of the original human diaspora.

It still seems surprising that in no society, anywhere in the world, did wizards manage to persuade the Muggles to accept them, perhaps as wise-women and medicine men, and thus become at least more common than an incredibly rare minority. The fear of practicioners of magic is by no means universal to Muggle cultures.

There was some discussion of genetics in the FF.net comments for Chapter 23; I'd like to continue that here.

Going purely by canon evidence, disregarding Harry and Draco's results, I would have inferred that magic was dominant, not recessive.

I assume that the magical population of Britain is much smaller than its nonmagical population, that the vast majority of magical children in Britain attend Hogwarts, and that the vast majority of Hogwarts students are British.

There are roughly a million 11-year-old Muggles in Britain. The number of Muggle-born witches and wizards in any given year at Hogwarts is counted in the dozens, at most. This puts the probability of any given child of nonmagical parents being magical at somewhere around 10^-8, which is plausible for a simple random mutation.

Wizard-born Muggles, on the other hand, are common enough that the word "Squib" was created to describe them. The level of understanding of genetics that Harry displays -- the level that Draco could have if he was paying attention, even -- is sufficient to realize that the frequency of Wizard-born Muggles falsifies the model they settled on.

What simple model describes both the canon evidence and the MOR!canon evidence (Harry and Draco's results)? The best I've come up with so far is "Eliezer falsified data to suit his preconceptions", which is distinctly unsatisfying. (This model will be verified if Chapter 23 is edited to make the percentage of Squib-born Wizards 75% rather than 25%, and it will be falsified if Harry and Draco eventually realize that their theory doesn't work.)

Does MOR explicitly mention there being wizard-born squibs? Because it seems to me that it's impossible for there to be muggle/squib-born wizards, there to be wizard-born squibs, and for magic being a single gene trait all at the same time.

That is, unless that gene behaves in a way that ordinary genes do not. For example, there could be a spell which de-magicks gametes - either as a curse, or as an unnoticed side effect. That would explain both the existence of wizard-born squibs and the shrinking population of magic users, without affecting the fraction of squib-born wizards.

comment by Pavitra · 2010-06-19T02:49:40.451Z · score: 2 (4 votes) · LW · GW

I don't think MOR explicitly mentions wizard-born squibs, but the original HP canon defines "squib" as a nonmagical child of magical parents. The existence of the word implies a certain minimum frequency of the phenomenon. I assume anything true in canon is true in MOR unless explicitly contradicted.

I, too, originally thought that it couldn't be a single gene trait, for exactly the reason you mention, until I realized just how rare muggle-born wizards were.

Other models have been proposed in the fanfiction.net comment thread. For example, there could be two gene traits, one controlling witch/wizard/squib vs. muggle with muggle dominant, and one controlling squib/muggle vs. witch/wizard with squib/muggle recessive. The parents of Muggle-borns would be carriers of the recessive not-a-muggle gene, and the parents of Squibs would be carriers of the recessive squib gene. (Note, though, that this still doesn't explain Harry and Draco's results.)

Because magic can have arbitrary effects, I prefer to assume nonmagical explanations wherever possible. Admitting magic essentially removes the possibility of being surprised by any observations.

According to Eliezer, the "muggle-born" are in fact the children of people who have one copy of the magical gene (and thus are descendants of Squibs who were cast into muggle society.). That only one in ten thousand people in Britain (who are not wizards themselves) have a copy of the gene for magic is not that improbable.

Hermione was right, Harry could have gotten them killed by trying novel tricks without any sort of precautions. And having seen the standard precautions, Harry understood this, which is why:

This ability is at least as dangerous as the killing curse, if not more so. People are objects. Harry can now transfigure, say, a chunk of someone else's brain into steel, or glass, or water. Turning someone else into a ferret is scary, yes, but they'll turn back little the worse for wear.

This makes Harry very, very dangerous, especially because he hasn't realized it yet.

I always thought the killing curse was overrated. Many of the spells that first years use in pranks on each other will get you a kill if you are carrying a knife in your pocket.

In 1 vs 1 combat stupefy beats avada kedavra. By about 3 syllables.

Don't forget that Avada Kedavra has the advantage that it can't be blocked/mitigated/etc, whereas spells like stupefy presumably can (or that advantage of AK wouldn't be worth noting).

More specifically, most spells can be blocked by the "protego" charm. AK cannot be blocked in this matter although AK can be dodged or can have a large physical object block it.

Presumably that at least allows him to break through any locks. Mastering this wandlessly will make it impossible to effectively restrain him while leaving conscious. The choice to make it possible is still on the author, because the Magic could make it impossible regardless, as it holds lots of conceptual knowledge already and can impose map distinctions of its own, however the wizard conceptualizes the situation.

Chapter 27

A lot of folks seem to make a big deal out of Harry not understanding Snape's "racist" comment. Which is very strange to me, as I had no idea it had that sort of implication (though it's obvious in retrospect), and (while I'm no expert) I'm much more familiar with the HP canon than Harry is. "Mudblood" always sounded more to me like making fun of someone for being poor.

It doesn't seem at all clear to me that this is realistic. The victims of the insult are, just about by definition, the ones who weren't raised in wizarding culture, and no earlier than age eleven do they hear this particular insult. Even though the components of the word "mudblood" are certainly impolite, I don't think it could cut as deep as a slur that floats around one's childhood environment and that one's parents are familiar with reacting to and so on.

No, it's not a direct equivalent, because the societies are somewhat different, but the racial analogue is clear, and comparing "mudblood" to "nigger" (or maybe "fag") is probably the closest analogy we have.

Also, the term can be used as an insult even to non-Muggleborns, who presumably have grown up with it. In fact, that seems to be how it's usually used to greatest effect. And the Muggleborns are transplanted from everyone and everything they know when they come to Hogwarts, so in some sense they have a new childhood environment with brand-new associations to be learned.

It seems like a class rather than race thing to me. Maybe this is partly because class divisions are more salient to me than race divisions with my British upbringing but given Harry Potter is a British creation I think class is likely to be the the closest analogy. It's the kind of treatment that a scholarship kid from a working class background would get in a public school#Associations_with_the_ruling_class). The fact that Hogwarts is modeled after public schools lends weight to this theory.

I don't buy the class analogue.

Aside from the racial (magical) view being perfectly consistent with everything in canon (magical/non-magical seems to override even xenophobia, witness the foreign schools' reception in Goblet of Fire), we also have a perfect example of one group of people who suffers from both class and racial discrimination: the Weasleys.

The Weasleys are presented as being mocked (particularly by the Malfoys) both for being poor - lower class, note also that their red hair suggests Irish roots - and for linking themselves with Muggles and eventually intermarrying with Mudbloods. If the 2 were one and the same, we would not see any difference.

I can't really pretend to be much of an expert on Harry Potter - I've seen several of the movies but I've never read any of the books. From what I've seen however the parallels to class in British society are clear while the racist connotations are less apparent to me. Discrimination based on physical features common to an ethnic group seems to me to be an essential component of racism which is largely absent in the movies.

In Britain wealth and class are correlated but distinct. The concepts of the nouveau riche and the distressed gentry are examples of how the concepts of wealth and class are not identical.

comment by WrongBot · 2010-07-01T01:00:09.168Z · score: 4 (4 votes) · LW · GW

I think it may be a bit of both. A large part of the negative sentiment towards muggleborns seems to come from the purebloods viewing them as interlopers into a superior culture that has no place for them, for which the nouveau riche are the perfect analogy. But at the same time, the conflict has a great deal to do with ancestry and heredity; Voldemort and his coterie, evil bigots that they are, want to stop the muggleborn outsiders from diluting their superior bloodlines, a clear echo of various racist ideologies. The tie is made even more explicit by Rowling's depiction of Grindelwald, Voldemort's predecessor as a Dark Lord and pureblood supremacist, who has a biography that carefully echoes Adolf Hitler's. Rowling is sometimes unsubtle.

(Disclaimer: I've read an embarrassing amount of fanfiction, and have sometimes been known to confuse canon and fanon.)

This is true, and the blood-purity issue is not entirely analogous to race. But Rowling went to quite a bit of effort to line her bad guys up with the Nazis. (Grindelwald ended up imprisoned in a place called Nurmengard, even!)

Mudblood can only be used to refer to muggle-born witches and wizards, making it a strictly racial and not socioeconomic term; many muggleborns, including Hermione, are actually quite well off. And it is definitely a big deal. Did you miss the gigantic brawl that ensued after Malfoy first called Hermione a Mudblood? I believe Ron was vomiting slugs for a day afterwards.

Read up to Chapter 26, commenting on same.

I don't quite see how this takedown of Skeeter is so brilliant. Ok, she's been convinced of something that's not true, but what of it? She's written untrue things before without getting into trouble. And the nature of the story doesn't seem particularly damaging to Lucius's interests either. Harry Potter engaged to Ginny Weasley, well, so what? It seems to me that Harry and Quirrell are both being very impressed with the technical difficulty of what's been done, without particularly considering the more relevant aspect of how damaging it is. They both just assume that Lucius will retaliate against Skeeter, but why should he?

Also, and related, I was rather disappointed at Skeeter dying like that. We don't get to see the effects of the brilliant takedown, they are merely asserted! Boring! Admittedly it's clearly the result of Quirrell's plans overlapping with Harry's, but narratively it's rather inefficient. It's one thing to have the hero suffer from two enemies both plotting against him, and show how he gets into even worse trouble because of how they interact, but a villain should not be defeated this way.

That's what I was wondering about the most. Perhaps the main difference is that her usual dishonest stories are written to be difficult to falsify — so it's technically her word against her victims' — whereas in this case she believes the story to be true, and perhaps the Weasley twins will have left specific proof that the story is false, or perhaps even made it appear that she had actively forged the evidence; this could compel the Daily Prophet to fire her (even if they don't really want to). It probably wouldn't do much to her reputation (sounds like everyone already hates her), but if it interferes with her career, her ability to disseminate information to wide audiences, that could indeed reduce her usefulness to Lucius.

Come to think of it, how do real tabloids get away with reporting week after week that every celebrity is having an affair with every other celebrity or is in drug rehab or whatever? Do the celebrities in question just not consider it worth the time or money to go after them for libel?

I suppose that someone could use Polyjuice potion and affect some of Neville's behavioral quirks, like his tendency to use ridiculous-but-cool "special attacks". Polyjuice is a difficult potion and has a month-long lead time, but it's not inconceivable that Neville could have made or otherwise obtained some. Considering all the scheming that's been going on after the first battle, it wouldn't even be that much of an ass-pull. Or there might be simpler disguise methods; since this is all taking place underwater, it's hard to see and the voices are distorted.

So, we need to postulate:

  1. Polyjuice potion made a month ago, by first years, for no reason they could know in advance
  2. A student who is an excellent enough actor to mimic Neville on the fly
  3. A student who is also skilled enough to learn the Breaker move (on top of his usual classwork and, of course, the Polyjuice potion)
  4. A student skilled enough at tactics to take on Weasley and win (see 1-3)
  5. A student who is somehow skilled enough for 1-4, but not as useful as Neville (so that becoming Neville's dead decoy is a net win)

I dunno, all of that seems like an asspull to me. And to what effect? Neville could've just swam off to 'play assassin' without all this. 'chaos' doesn't seem like a sufficient explanation.

Chapter 29 - Am I alone in considering this the worst chapter yet (that is, <=29)?

The hacked in "Bill is schizophrenic" was unpleasant. Sure EY wanted to force in a 'conspiracy theory' lesson, but I still just found it distasteful. The remainder of the chapter was just uninspiring and did nothing but reinforce my growing impression that Harry doesn't have what it takes to become an ultimate "Universe Optimising" power. I don't think all of this is due to 'still needs to learn lessons' considerations either.

Ick. I'm going to read the next couple of chapters. Most of the recent comments here have focussed on the the 30,31 chapters so I'm hoping 29 was just an unremarkable interlude.

I'm still a little unsure about this. It's writing off the canon plot as a conspiracy theory, but Eliezer surely knows that sometimes conspiracies are correct (a few are stranger than fiction; besides the well known Gulf of Tonkin, there's also Operation Gladio or Propaganda Due) and that they really are out to get you. Cryonics, for example has been written off as a conspiracy theory by some.

And from a writer's perspective, it rearranges a lot of characters. Aside from Pettigrew now being dead as he's supposed to be, Sirius is now stuck in Azkaban, Bill is AWOL at Mungo's, and Remus has much less motivation to come in. My hope is that Eliezer actually has a different conspiracy cooked up which will use those characters, and it'll be a lesson in 'following the hard evidence no matter how silly/low-status/conspiratorial outsiders consider the theory' (with obvious relevance to cryonics).
