How do I organize a LW meeting in a city (and perhaps the entire country) where I strongly suspect nobody else visits LW.com?

Pick a date, time, and location that seems sensible. Post a meetup. Say "I'm flexible about details, if this point in spacetime doesn't work for people". At the specified time, show up with something identifiable, and a book or some work that you can do to keep you occupied for, say, two hours in case nobody shows up. Hope somebody shows up.

Or feel free to say "I will only be there if I get at least N replies", where my own preferences would place N at one or two but YMMV. That reduces the probability of being bored and alone, but also reduces the probability of successfully meeting someone.

If you wanted low-level technical details, this is how I do it:

I have a phone number to a cafe, where I already did some meetups, so I call them to reserve a table for me on Monday from 18:00. They have no problem with it, even if I say "I am not sure how many people will come, at most 10 but maybe much less", because on Mondays they are half-empty anyway.

When I did this the first time, I used google and recommendations from my friends about nice places in the city. Then I visited personally (to see the place, and to be able to negotiate in person) and asked whether it would be okay to have a table reserved there. -- I specifically emphasised that most participants will be students who don't have much money and just want to talk, so they shouldn't expect a big revenue from this; and I asked whether that would be acceptable. (It's better to have a feedback in advance than a misunderstanding later.) -- Then I picked a Monday cca 2 weeks in future.

I post an announcement on LW, and also to the local LW mailing list. Sometimes I send personal e-mails to people I think could be interested. (Mostly they don't come, but sending the e-mail is so cheap and sometimes they come, that it's worth doing. Some people don't come the first few times, and then when I already lost hope, they appear.) -- At the beginning I also used to post an invitation on my Facebook page.

A day or two before the meetup, I send e-mail reminders. The e-mails contain my phone number, in case someone would have last-minute problem finding us.

I go to the meetup. -- At the beginning, I was careful to be the first one there, and to somehow attract other people's attention (e.g. have a paper saying "LessWrong" on the table). These days we already know each other, and we meet in a cafe that has only three tables, so this is not necessary.

There are two problems here: (1) Increasing the visibility of LW among minds which could be positively influenced by it. (2) Coordinating the already interested minds to meet at one point in the timespace.

You asked specifically about the latter, but I want to make it explicit that the former is a meta-strategy for the latter. The more people know about LW, the easier it is to get some of them to the meetup. (These is a chance -- although I wouldn't rely on it -- that with popularity big enough, someone else would organize the meetup.)

As a data point, the first meetups in Slovakia had between 4 and 6 people. And even that was because there were already 2 organizers (me and my girlfriend, and she did it partially to make me happy), and at that time there were no regular meetups in neighbor countries, so we regularly had one or two visitors from other country. It took more than a year to create a relatively stable community of about 10 local people. And I had to make some trade-offs; for example a few of them are not fluent in English, so we speak in Slovak, which excludes the potential foreign visitors.

I am saying this to prepare you not to be disappointed by smaller participation. On the other hand, there are a few possible strategic moves I have ignored so far (such as doing a LW presentation at a local university), so a better strategy could possibly bring higher participation.

There seems to be a pretty sharp lower bound on how cheap a living situation (e.g. rent on an apartment) can be in the parts of the United States I'm familiar with. I would have thought that there would be demand for cheap-but-bad housing on the part of people with low income. Here are some hypotheses I've come up with for explaining this, and I'd appreciate anyone who has relevant knowledge commenting if I'm on track:

  • There is in fact very little such demand in the US because people who can afford any kind of rent at all have grown accustomed to a certain standard of living.
  • The cost of complying with health and safety regulations makes it too expensive to price rent below a certain amount even at the worst the rental situation is legally allowed to be.
  • The people who would try to rent as cheaply as possible are also the people who are least likely to pay their rent (e.g. due to job insecurity), and landlords don't want to take on the additional risk.

There's also zoning laws. For instance, I live in DC, where there's a height cap on buildings, which makes it impossible to build towering, cheap, apartment buildings. (much to my sorrow).

That zoning law exists to keep buildings from blocking views of the Capitol, but a lot of other zoning laws exist exactly to prevent cheap apartments, because the people active in the zoning process don't want to live near the kind of people who would live in cheap apartments.

Robert Moses, from my home state of NY, is particularly famous for this kind of things. In addition to zoning, he also made sure that buses weren't allowed on some Long Island roads, or that bridge overpasses would be too low to fit buses under, to prevent people who rely on public transportation from traveling to certain neighborhoods and beaches.

Height caps are overrated. Paris is five times denser than DC, but I believe that its height limits were stricter in the 20th century.

The cost of complying with health and safety regulations makes it too expensive to price rent below a certain amount even at the worst the rental situation is legally allowed to be.

There's also zoning and other issues, and subtler ones like licensing of construction trades, etc. But this seems to be a big part of the story. From last year http://www.psmag.com/navigation/politics-and-law/how-the-trailer-park-could-save-us-all-55137/

By any name, they are the largest source of unsubsidized affordable housing in the country. There are seven million manufactured homes housing 18 million people. In some counties they make up 60 percent of dwellings. Approximately one out of every 12 Floridians lives in a manufactured home. Units built since 1976, when the Department of Housing and Urban Development started regulating their construction, can last as long as site-built homes when they’re well built and maintained. Yet they cost far less: $41 per square foot versus $85 per square foot and up. At least one study, from the University of Illinois-Chicago, on trailer parks in Omaha, Nebraska, found that crime rates in mobile-home parks are the same as the rest of the community; the parks do not cause crime nearby; and that the parks appear to depress crime levels because residents own their homes. In one survey, nine out of 10 owners of manufactured homes said they were satisfied with their dwellings. They’ve found a housing option that suited their budget and needs.

The middle class would prefer that people be homeless than that they have permanent dwellings that do not reach their standards. None of your explanations is correct but the second comes closest. See Flophouse. I believe Matthew Yglesias has written on this and there's a commenter on slatestarcodex, St. Rev, who may or may not have a blog, who's homeless.

  • The opportunity cost of the land may be higher than you think. How far from a major population area are you looking?
  • Transaction costs (an expansion of your third point) are higher than you think.

Do an estimate of what it would take for you to set up a group home in the areas you are willing to live. If you're lucky, you will be able to find partners and get it going for a bit under going rental rates. If not, you'll learn a lot and be able to report back here.

What do you mean by "bad" housing?

One possible reason is that many of the relevant aspects of good or bad housing are governed by building codes (plumbing, HVAC, bathrooms, room size, etc.) which put a (often high) lower bound on how cheap a building can be built. In addition, the organization of the construction industry (many specialized subcontractors) means there's a fairly high fixed cost for any new construction. While this mostly applies to new construction, it can apply to existing buildings as well.

I'm trying to figure out if I

  • have an average memory, but the availability heuristic biases me toward finding examples of other people remembering things that I don't remember, or

  • I have a below average memory.

I guess I think this is a stupid question because how are you supposed to help me answer it via online message board? But it seems like kind of a typical problem to have, being unable to tell the difference between "I'm performing fine but I disproportionately notice my mistakes" and "I am actually performing poorly."

This seems easily testable. Though I cannot recommend any, I'm sure there are online memory tests that let you know how you performed relative to all the other subjects. Maybe not good enough, as there is a selection bias in the sample of people who take those tests, but it will give you some info.

However, I think that you have an above average memory and are only noticing this because you usually hang around people who have above average memory as well[1]. Perhaps a more useful test would be getting your friends to take the test as well and compare the results. Maybe ask on LW for subjects? I'd participate.

[1] Assumptions:

  • You have an above average IQ. I a priori assume this of all LWers.

  • There is a positive correlation between IQ and memory. A quick search gives results in favor of the assumption, but I didn't dig deeper.

  • You hang around people of similar IQ.

Memory is a complex process and there are different kinds of specialized memory modules in the brain. Have you noticed that you have a problem with specific kinds of memories? Do you have problems with attention? You might not encode the memories in the first place.

Can anyone explain the Olympics' tournament system to me? Team A beats Team B and advances to the finals. Team C beats Team D and advances to the finals. Team A beats Team C. Team B and Team D now play for third place, and Team B wins. Team A is awarded the gold medal. Team C is awarded silver. Team B is awarded bronze. What's up with that? Team B and Team C have the same win/loss record. They both beat Team D, and lost to Team A. Why does Team C get the silver?

I've wondered about this too. I once tried to organize a round-robin tournament, and discovered that all the other players preferred single elimination despite its vulnerability to noise and lack of a meaningful second place. In the ensuing argument, I discovered that they do know about problems like this, but they don't care, for two reasons:

  1. They don't care much about accuracy. Tournaments ostensibly rank teams by quality, but they're used mostly as ritual contests: the audience wants to know who won, not who would most likely win.
  2. They don't like complexity or novelty. They're suspicious of any design they don't understand, because they're afraid it might be gamed, or might have perverse incentives (e.g. where losing a match helps you win the tournament), and because they want everyone, even the dumb jocks, to understand the rules.

from Wikipedia

In a random knockout tournament (single-elimination without any seeding), awarding the second place to the loser of the final is unjustified: any of the competitors knocked out by the tournament winner might have been the second strongest one, but they never got the chance to play against the losing finalist. In general, it is only fair to use a single-elimination tournament to determine first place. To fairly determine lower places requires some form of round-robin in which each player/team gets the opportunity to face every other player/team.

Well, on the surface level, Team B lost their first match and won their second, while team C won their first match but lost their second, so clearly order matters.

On the more meta level, a format optimised for selecting one winner has been poorly adapted to the task of selecting three winners and ranking them. Adjusting the format to fairly select silver and bronze would add complexity and cost and time, and apparently not enough people care enough about fairly selecting silver and bronze for this to have happened.

The anti-death argument you are implicitly referencing only states that "Death is bad", not "we have to feel negative emotions in response to death".

There's nothing wrong with coming to terms with it, as in "this bad thing will probably happen to me, and I accept that it must be so". It's like if you lose a limb - its possible to come to terms with that even if it's clearly bad.

Along these lines, if we pretend there is actually a zero percent chance of curing death in our lifetime, how should we rationally act differently? Often people use the cliche 'if you were going to die tomorrow what would you do differently today?' as a thought experiment, seemingly implying (to me at least) that we're already living rationally for an ~80 year lifetime and that only changes in behavior should come from learning you have a very short time to live left.

I often wonder if I too easily approximate ~80 years as infinity in my reasoning about life, and that I'm not appropriately taking into account an 80 year life span (or much shorter if you subtract sleep, how old you are now, and years of life you think you'll be healthy enough to have control over).

TLDR: I think it's hard to reason about spans of time that are longer than we've experienced but shorter than infinity, and I don't know what to do about it.

I often wonder if I too easily approximate ~80 years as infinity in my reasoning about life

Imagine a large paper divided into 100 x 100 squares. One of those squares, most likely at the bottom part of the paper, contains an invisible mark. Every day you remove a square. When you remove the one with the invisible mark, you die.

(If you are a student, you have more expected days remaining, but you should be aware that they will be on average less useful than the ones you have now, because generally, as you grow older, you have gradually more duties and worse health. So you probably should imagine 100 x 100 days, even if you have more, to compensate for this bias.)

Too much or too little? Think about the activities and plans you were doing recently, to calibrate yourself how many squares would each of them cost. (Include the days when you were too tired or too busy to do anything useful, because those days passed too.) This gives you an idea about how much can you do. Now think about the things you did 10 years ago; how happy you are you did them; how many of them do you even remember. This gives you an idea about how you will feel 20 or 30 years later about how you spend your time now.

Who would be willing to fund this research? The cryonics organizations usually run at losses (membership and preservation fees do not pay 100% of expenses) and don't have the money for much research. And the public doesn't care - have you donated to the nearest available equivalents like the Brain Preservation Prize? If you haven't and are unwilling, then you have your answer.

Because anything bigger than a cubic centimeter or two that you try to vitrify always comes out of vitrification full of massive cuts and chemical toxicity and ice crystals and leaky membranes to the point that calling it temporarily 'alive' is a stretch. This is not a problem with the revival process, but with the preservation process. Even freezing samples of cultured cells has a mortality rate.

Because cryonics is not simply about putting people under liquid oxygen.

It also involve given people a highly toxic substance that prevent ice crystals from forming inside their brains. The substance does no harm if you are frozen is ice but if you would just try to revive people the substance would kill them. You need nanotech to remove it.

Cryonics needs nanotech to revive patients. Currently there no good nanotech for doing so. It makes more sense to wait till we have good nanobots and then attempt to revive organisms.

Well, but for sufficiently small things one may be able to get by without too toxic cryopreservants? Famously, things like embryos and even rabbit kidneys have been frozen and then "revived". If this could be scaled up to e.g. a mouse (something which is big enough to have nontrivial memories), that would resolve lots of worries about there not being enough information preserved in a vitrified brain.

You can freeze nematodes and water bears fairly easily. Notably both of these are evolved to survive dessication and freezing in their normal life cycle and have their largest dimension on the order of one mm. Its a bit of a stretch to call what some frogs can do naturally in the outdoors 'freezing' but again, massive evolutionary pressure.

If you try to freeze a complicated structure bigger than a few cubic centimeters that isn't the ridiculously vascularized and quite small and very homogenous in terms of water content rabbit kidney, you come up with something that is so damaged by the freezing process that it falls apart physically and chemically upon unfreezing. The unfreezing part is not the limiting factor, because there just isn't a paused functional organism left behind by the freezing process.

Should I take a proper IQ test?

In the past I've only ever taken those questionable online IQ tests, and managed to get something like 133 from them, but they're obviously not the most reliable source.

The only other really IQ-like test I've ever taken was the Otis-Lennon test in grade 4, which I only got 114 on. But I also remember misunderstanding the instructions and thinking I wasn't allowed to skip questions, so I only actually answered 50 of the 75 questions on the test (I got stuck on question 50 for a long time).

I also more recently managed exactly 160 (80th percentile) on the LSAT on my first and only attempt.

And, most recently I took a Differential Aptitude Test that looked like:

  • Verbal Reasoning: 48 (97th percentile)
  • Numerical Ability: 25 (40th percentile)
  • VR + NA: 73 (70th percentile)
  • Abstract Reasoning: 40 (80th percentile)
  • Clerical Speed & Accuracy: 40 (25th percentile)
  • Mechanical Reasoning: 54 (45th percentile)
  • Space Relations: 42 (60th percentile)
  • Spelling: 89 (97th percentile)
  • Language Usage: 36 (70th percentile)

As you can see, it's kinda all over the place.

I am kind of curious about how I'd do with a proper IQ test, but I'm also a bit worried that I might be disappointed by the results. My own personal estimate is that I'm probably around 120 or so, since that puts me above average, but doesn't put me in genius or Mensa territory. And yes, I'm admitting that my own self-evaluation is that I probably have a lower IQ than the average Less Wrong survey answerer's 138. You people are scary intelligent. :P

And I wonder whether or not a higher than expected IQ result will make me overly arrogant, or a relatively low IQ result will hurt my confidence in the future.

So what do you think? Is knowing your IQ generally a good thing? Or are there good reasons for ignorance being bliss?

I wouldn't bother. If you're old enough to be taking the LSAT, a high IQ score won't be opening any worthwhile doors for you; at a younger age you might have been able to leverage it into admission to some useful programs, but now it's only good for bragging rights. And it's not something that it's socially acceptable to brag about in most contexts. (I don't remember ever mentioning mine past high school, except on the mostly-anonymous LW surveys.)

I currently use Mnemosyne 1.2.2, and have a deck of over 2,000 cards, including pictures, html, LaTex, etc. Ideally I'd like to be able to review these on my android phone, but whenever I've tried this, I've run into sufficient problems that I've given up.

  • I tried upgrading from Mnemosyne 1 to Mnemosyne 2, but a large fraction of the cards were damaged in the translation (for example, I'd often made double-sided cards, then deleted one side, in Mnemosyne 1, but Mnemosyne 2 was not happy about this).
  • I've had trouble getting Mnemogogo to work, and it seems (but I'm not sure) that Mnemododo assumes you have Mnemosyne 2?
  • Should I move over to anki?

This could save me a huge amount of time, but I have developed a big ug field around it and would appreciate someone knowledgeable would give me an easy, taskified solution.

Which are the most beautiful mathematical or physical equations?

I am interested in the elegance of the equation itself (not its visualization, e.g. the Mandelbrot set). Yeah, I know that there is a difference in opinions, but I hope there will be some correlation among experts. I would like to have, let's say, 5 candidates.

This is a specific example, and a very good candidate, IMHO:

e^(i π) + 1 = 0

I would like to have about 5 equations, not just one, so even if you agree with my choice, please post even the equations that seem a bit less impressive, but they still have some kind of beauty in them.

Okay, just to give you another anchor, this one is nice too, but much more simple:

a^2 - b^2 = (a + b).(a - b)

I didn't think about this part, because originally I was only thinking about math. Thank you for giving specific examples, so I can test my intuition to them.

Uhm... I'd say that "Δ . B = 0" doesn't trigger my feeling of awesomeness, however important it may be. Even "E = m * c^2" doesn't, and that has a lot of applause light connected with it. They are just too simple; they feel like "a + b = c".

On the other hand, I realized that if I don't know what the equation means, I can't decide whether it is good enough. So the meaning is a part of the utility function, but mathematical elegance is another part (the feeling of "oh, this is really equal to that?" like when the pieces of puzzle suddenly fit together) -- and I want the equations that satisfy both criteria.

Squark's examples are already great enough and probably all I need, so if you had some specific examples in mind, please post them here, but otherwise I already have what I wanted.

Most of my friends are big fans of heavy metal, but I abhor it ardently. I can match your example by saying heavy metal is unduly overrated, plus I do happen to think it sucks. One part of my head feels inclined to say that a judgment of sucking is a necessary component of the judgment of overratedness. However, I also think Finding Nemo is overrated, but I don't think it sucks. This leads me to think there are degrees of overratedness; i.e. my tastes place Finding Nemo on a much higher position of enjoyability than all of heavy metal.

My friends who love heavy metal will accuse me of committing your proposed fallacy; they could say I'm not justified in saying heavy metal sucks just because it fails to please me. But if someone else says Finding Nemo sucks, I won't blame them, even if my dislike for it doesn't go that far.

It's difficult to name a formal fallacy of personal tastes. It's one thing to detect a flaw in matters of true/untrue, but quite another to say that there can be flaws in matters of like/dislike.

My study partner insisted that Prof. Lewin was wrong, and that Kirchhoff's rule applied in this case because the inductance came from within the circuit itself.

I would really appreciate it if anyone here could help me understand (with linked sources if necessary) whether Kirchhoff's rule is applicable here. If not, why? Can you explain it in a way that would make my study partner understand it?

I've been trying to wrap my head around arguments involving simulations, e.g. what to do if Skynet (replace with whatever AI you prefer to hate) threatens to torture a large number of simulations of you, etc.

Here is my stupid question: why can't we humans use a similar threat? Why can't I say that, if you don't cooperate with my wishes, I'll torture imaginary versions of you inside my head? It's not like my brain isn't another information processing device, so what is it about my imagination that feels less compelling than Skynet's?

I no longer find it totally implausible that imagined people might, if modeled in enough detail, be in some sense conscious -- it seems unlikely to me that human self-modeling and other-modeling logic would end up being that different -- but even if we take that as given, there's a couple of problems with threatening to imagine someone in some unpleasant situation.

The basic issue is asymmetry of information. You might be able to imagine someone that thinks or even reliably acts like your enemy; but, no matter how good you are at personality modeling, they aren't going to have access to all, or even much, of your enemy's memories and experiences. Lacking that, I wouldn't say your imagined enemy is cognitively equivalent to your real enemy in a way that'd make the threat hold up.

(Skynet, by contrast, might be able to reproduce all that information by some means -- brain scanning, say, or some superhuman form of induction.)

You can't simulate anything in the relevant sense.

My own thinking about this whole class of questions starts with: is the agent threatening this capable of torturing systems that I prefer (on reflection) not be tortured? If I'm confident they can do so, then they can credibly threaten me.

Among other things, this formulation lets me completely ignore whether Skynet's simulation of me is actually me. That's irrelevant to the question at hand. In fact, whether it's even a simulation of me, and indeed whether it's a person at all, is irrelevant. What's important is whether I prefer it not be tortured.

A lot of ill-defined terms ("person", "simulation","me") thus drop out of my evaluation.

In principle I expect that a sufficiently capable intelligence can create systems that I prefer not be tortured, but I'd need quite a lot of evidence before I was actually confident that any given intelligence was capable of doing so.

That said, the problem of evidence is itself tricky here. I expect that it is much easier to build a system I don't endorse caring about in the abstract, and then manipulate the setting so that I come to care about it anyway, than to build a system that I endorse caring about. That said, we can finesse the epistemic issue by asking a different question: is the intelligence capable of creating (and torturing) a system S such that, if I somehow became confident that S has the attributes S in fact has, I would prefer that S not be tortured?

My confidence that humans have this ability is low, though (as above) in principle I expect that a sufficiently capable intelligence can do so. Certainly I don't have it, and I've never seen significant evidence that anyone else does.

Have you?

So first of all, a purely syntactic remark: this involves a rather unnatural construction, taking "X's quotation" to mean what you get by putting X in quotation marks. So far as I know, no one ever uses the word "quotation" in this way except when talking about Quine's construction (i.e., the thing we're talking about now). OK, let's proceed.

The version of this I've seen is slightly different (and avoids Creutzer's complaint):

"yields a falsehood when preceded by its quotation" yields a falsehood when preceded by its quotation.

So, let Q be the sentence-fragment "yields a falsehood when preceded by its quotation". Then for any sentence-fragment R we can construct a sentence ["R" Q], and what it says that ["R" R] is false.

E.g., if you say ["foo" yields a falsehood when preceded by its quotation"] you're saying that ["foo" foo] is a falsehood. Now, of course in this particular case that's wrong because ["foo" foo] is just nonsense, not a falsehood. So ["foo" yields a falsehood when preceded by its quotation] is wrong.

Or consider ["is a sentence fragment" is a sentence fragment]. That's true, so ["is a sentence fragment" yields a falsehood when preceded by its quotation] is wrong.

So, in general, ["R" Q] is a sentence -- call it S -- saying what you get when you construct the possibly-a-sentence ["R" R] -- call that T -- and in particular claiming that it's a falsehood. That is: S says that T is false.

Now, what happens when you let R=Q? Well, in that case S and T are both ["Q" Q] or, writing it out in full, ["yields a falsehood when preceded by its quotation" yields a falsehood when preceded by its quotation]. S says that T is false, but in this case S=T, so S says that S is false.

In other words, it's an Epimenides-style paradox but without explicit self-reference. Instead we have a sort of self-reference by construction: we've got a sentence that says "Build a sentence according to such-and-such a recipe; the result is false", and it just so happens that when you do what it says the sentence you get is that sentence.

This is quite closely analogous to how some metamathematical proofs work -- e.g., Goedel's theorem is proved by constructing a mathematical proposition S that in some sense says "S is not provable", and Tarski's theorem by constructing (assuming you have a way of expressing "is true", which is what we're trying to prove is impossible) an S that says "S is not true". (Note: Everything in this paragraph is at best an approximation to the truth, with the possible exception of this parenthetical remark.)

comment by DavidS · 2014-02-21T06:41:59.103Z · score: 0 (0 votes) · LW · GW

The grammar of the sentence is a bit hard to follow. When I am presenting this paradox to friends (I have interesting friends), I hand them a piece of paper with the following words on it:

Take another piece of paper and copy these words:

"Take another piece of paper and copy these words: "QQQ" Then replace the three consecutive capital letters with another copy of those words. The resulting paragraph will make a false claim."

Then replace the three consecutive capital letters with another copy of those words. The resulting paragraph will make a false claim.

I urge you to carry out the task. You should wind up with a paper that has the exact same words on it as the paper I gave you.

If you believe that the statement on my paper is true, then you should believe that the statement on your paper is false, and vice versa. Yet they are the same statement! Assuming that you think truth or falsehood is a property of grammatical sentences, independent of where they are written, this should bother you. Moreover, unlike the standard liar paradox, the paper I gave never talks about itself, it only talks about a message you will write on some other piece of paper (which does not, in turn, talk about the original message) when you perform some simple typographical operations.

Quine constructed this example to demonstrate the sort of subtleties that come up in order to invent a mathematical formalism that can talk about truth, and can talk about manipulating symbols, without bringing in the liar paradox. (To learn how this problem is solved, take a course on mathematical logic and Goedel's theorem.)

I suppse the intention is for this to be another version of This sentence is false, but it fails.

The sentence

(1) "Is false when preceded by its quotation" is false when preceded by its quotation.

says that the string "Is false when preceded by its quotation" has the property of being false when preceded by its quotation. The sentence is, in fact, that string preceded by its own quotation. However, there is no paradox. The whole sentence (1) can be true, and then the italicised occurrence of the string "Is false when preceded by its quotation" is false. No problem there. Incidentally, it's dubious to ascribe "is false when preceded by its quotation" a truth-value anyway, since it's not a sentence, but merely a verb-phrase.

One could change it to "yields falsehood when predicated of its own quotation". Then you get the sentence "Yields falsehood when predicated of its quotation" yields falsehood when predicated of its quotation, which looks more paradoxical. However, I'm not entirely clear that it really is a paradox, either. There might be some confusion there between predicates and strings that refer to predicates. It depends on how quotation in natural language really works...

This is probably a stupid question:

How is rounding error not a fatal flaw in brain simulation? Meaning, even if you could copy the workings of someones brain perfectly, it's presumably still a calculation done on some computer in some way. So even if you store the first X digits of every number in the calculation, it would at some point diverge from what the real brain did, even if it took a very long time.

Therefore is it fair to call that copy that 'person' or rather do you have to switch to speaking in terms of fidelities: that copy is Y percent the original person and diverges at a rate of Z percent every so many steps?

Yes, the two will diverge. But then, so they would even without rounding error, on account of quantum mechanics.

Neither of them is "the original person" (you are not, now, quite the same person as you were a year ago). Both are, so to speak, descendants of the original person. There are many (apparently) possible descendants -- you never know what might happen to you, after all. A good enough simulation would be as much like one of those as they are like one another.

The shortest thing to read would be his paper "Why It Is Better Never to Come into Existence". He also has a book titled "Better Never to Have Been: The Harm of Coming Into Existence".

No. Not purely from that knowledge about your utility function, anyway.

Unless suffering has infinite disutility, then enough happiness would outweigh all the suffering in the world.

If we reach a Good Future, then it would be worth it even if the average modern human has negative utility - which seems far from obvious itself, even given the premise; most human lives could still experience sufficiently more happiness than suffering.

Only if you also do not expect there to be enough happy living to outweigh the amount of suffering.

This just doesn't seem right. Perhaps no amount of happy living outweighs suffering beyond a certain amount.

Well, that sounds obviously wrong - it would mean you could start with a universe you liked, scale up the population without changing average quality of life at all, and end up with a universe in which you want to destroy all life.

I think you're talking past each other. Rowan is assuming the amount of happiness and suffering to be distributed across several people, where adding another person with the same suffering/pleasure ratio shouldn't change anything, and dunno is, I believe, talking about a single person's perspective where, once you've reached a certain amount of suffering, it might be impossible to outweigh it.

In that case (which I believe is not true for almost any modern human, so this is a purely theoretical answer), it's logical to conclude that it'd be good for you to cease to exist. In order to prefer that others so cease (assuming you're a utilitiarian), you'd need to believe that every individual has a similar weighting.

If I ceased to exist there would still be people that suffered without a choice. Ceasing to exist wouldn't change this while if everything ceased to exist, it'd change.

So I accidentally came across this today and although as a super cynical person i always assumed this was how the super rich often, but not always, behaved, it was pretty depressing to see solid evidence. Yet whenever events of this nature come to light, both society in general and people I know in particular never seem to change their behavior much. Maybe some people do the "post an article on facebook; pretend you contributed to society" type "activism". Why is it that most people don't care about this stuff? Maybe they are just already overwhelmed by bullshit?

Some rich people get together occasionally to eat overpriced food, make tasteless jokes, and impose humiliating initiation rituals on their slightly less wealthy aspirational juniors? That's pretty tame, as bacchanals go. If I'm to treat Wall Street like Thulsa Doom, I expect human bones in the soup and at least one giant snake.

Was it Buffy where the rich people society fed sacrifices to a snake demon for luck? That was a great episode.

My main issue is with the Bailout King part I suppose, although the other problems annoy me also. That's indicative of their beliefs about the poor and the government. Sort of like what Romney did in that 49% speech that was leaked.

Its clear they didn't think it was tame, hence the violent threats and later attempted bribery to keep it quiet. Its not like they feared retaliation from above for a PR gaffe, since its all top level people. So they must have a reason for being so upset.

I was referencing Conan the Barbarian (the movie, not the short stories), but yeah, there was a Buffy episode like that too. Or maybe it was Angel, I forget which.

In any case, I absolutely agree that the activities reported were in poor taste and quite possibly reflective of some questionable attitudes. But I'm hesitant to draw strong conclusions from this sort of reporting, mainly because of base rate neglect: this doesn't tell us what the average Wall Street honcho gets up to when they're at home. It doesn't even tell us the average for that party. You get what you see: a general impression and a short list of lowlights. The impression doesn't surprise me much (one doesn't sneak into a fraternity party with a camera if one wants to paint it in a favorable light), and the examples aren't much better: I've been to plenty of parties with behavior as bad or worse. For example, there's the one anime con I've been to (once and nevermore)...

Well, I'm certainly aware of actual fraternity parties with drag being used to humiliate, hell our soccer team tried to make the freshman, and sophomores because when we were freshmen there was a newly created ban, dress in traditionally female clothes. And of course general misogyny and homophobia.

But you've been to a lot of parties where one of the main activities was to denigrate the gullible poor/voting public wrt shady financial stuff?

As far as the average guy's beliefs and behavior, it kinda does. In such societies the behavior of the top level says a lot about the social norms. I mean its not as good as a peer review study or a survey maybe, but fat chance getting evidence of that caliber in an legal manner.

Was it not clear from the example that I meant bad behavior in a broader sense?

I could go into details, but they'd be irrelevant; the point is that you can paint an unflattering picture of many, many subculture events if you're so inclined, especially if there's drinking involved. All e.g. the "Bailout King" episode tells us is that some people at this specific party interpret as an outgroup people who're politically critical of the finance sector. Yeah, and... ? Subcultures generate us-vs.-them behavior and weird insider rituals; it's what they do.

You keep saying paint a bad picture. That usually means unfair spin. I'm not sure that's the case here.

As far as your assertion about the Bailout King song, I disagree. Certainly if we were looking at 100% solid objective evidence then what you suggested is all we can conclude. I don't know about you, but I don't make decisions only on a 100% chance of truth.

Subculture wise, I don't give a shit what some random anime con subculture does. I care quite a bit, and I believe quite reasonably, about the behavior of a group who controls a significant portion of the US and Global economy.

Much like the supreme court, I apply strict scrutiny, although in a more colloquial sense, to issues with broader social significance.

This would be evidence for the attitudes our reporter is attributing to his subjects... if the reporting was unbiased, not in the sense of "lacking an ulterior motive" but in the sense of "proportionately likely to report each option". (Technically individual data points are still evidence, but potentially much weaker; aggregated ones can in some circumstances be negative evidence.) Given the reporting slant and indeed the fact that we're discussing journalism, however, I don't believe we can rely on the provided interpretation of events. I'm willing to take the article as strong evidence that the events themselves did occur -- we're not talking tabloid journalism here -- but that's all.

More generally, I think it's unreasonable to expect perfectly restrained private behavior -- and that is what we're talking here, if you accept that upper-echelon Wall Street social circles constitute a subculture -- from people regardless of their wealth or power. Their behavior as regards the disposition of that wealth and power is socially significant, as to a lesser extent is their public facade. What they do behind closed doors doesn't concern me.

Its not their lack of restraint that is at issue, its what belief they demonstrate themselves to hold with this particular lack of restraint. Given the events that proceeded this story, wrt the financial sector, its seems quite likely that these beliefs demonstrated in private are in fact the ones they truly hold and which they act upon. After all the original story was about the fate of newbie financial professionals post-Crash. Maybe you could discount this behavior in the time before the Crash, but we have clear and well known evidence of the results of the actions of these people, and then we see them partying and laughing about how they avoided any significant consquences.

In general most people don't think of themselves as actors. The think of themselves as the audience of whatever happens on TV or in the media.

In some sense, I even doubt whether focusing on how people misbehave on a fraternity party is very useful.

Most energy shouldn't be focused on attacking the status quo but on building viable alternatives.

I'm not focused so much on the misogyny or homophobia as their attitude about the bailout and the poor. That they act like fraternity people isn't really an issue. But its a clear demonstration of their private contempt for anyone who isn't filthy rich.

As far as viable alternatives go, America was supposed to be a viable alternative to monarchy, but really it just put a new label on it. The world's history of making viable alternatives is pretty crappy. Most social change appears to have come from attacking the status quo.

Could you be more specific about what exactly you would like to be different?

Do you think that despising outgroups is a rare behavior, and we should remove all power from those who do? Do you think it is a frequent but not universal behavior, so we should find those exceptional individuals who don't have it, and give all power to them? Do you think the attitude is universal, but we should make sure that the powerful people are never allowed to express it, even in privacy (in other words: that the powerful people should have no privacy)? Something else?

Well, its an interesting question. I know that there are rich people who don't behave this way. So I can conclude that its possible to have a situation where large numbers of the wealthy or powerful don't have contempt for or outright despise the poor. My ideal would probably be a situation where people who felt/acted this way were an extreme minority. I don't think it requires exceptional individuals.

This suggest we should research the causes of what makes people behave like they do. Then we could perhaps try to systematically increase the things that contribute to nice behavior.

(By the way, this is where I think most people with egalitarian feelings often fail. They notice that some rich people are abusive somehow, and their reaction is: "punish the rich". The problem is, the punishment usually applies at least as much to the good ones as to the bad ones; and it may actually decrease the ratio of the prosocial people among the rich. It would be better to think about ways that could increase the ratio, but that is not compatible with the emotions created by outrage e.g. from the linked article.)

By the way, you speak about "rich", I speak about "powerful". It correlates in our society, but it's not the same thing. (For example, a powerful and stupid bureaucrat may be able to harm thousands or millions of people, without putting money into their own pockets; if they truly believe in their wrong ideas and try to do the right thing.) It could be relevant to this topic: maybe power corrupts, but mere money without the feeling of power don't.

I think it's very naive to think that when you break down a system the thing that replaces it will be automatically better. Failing forward is no good strategy.

Most social change appears to have come from attacking the status quo.

I don't think that's the case. The workers movement that lead to communism was strong because unions happened to be strong communities with strong internal loyalty.

If you want to change something focus on community building. Don't focus on what happens on the national level but focus on providing services that help people in your local community. The LW community isn't really local but it's also a community separate from the mainstream so, investing effort into making it stronger also counts as community building effort.

Don't invest your retirement money in the stock market. Invest it into a business where you know the owner personally. That can mean Angel investment.

Buying local property is also good. Buying solar panels to put on your house also decentralizes power.

If you invest your retirement money into an index fund you are actively supporting the current system. If you do protest against the rich and have your retirement money in an index fund you are not being consistent.

I put major effort in Quantified Self community building. As part of that community building I did a lot of media interview and used some of that time to say how much the status quo fails people and that people should gather data to make self determined choices instead of listening to authorities.

I do my fair share of attacking the status quo, but in the end the things that matters isn't destroying the status quo but replacing it with something better.

Having a QS community that's strong enough to be a stakeholder with certain power is a worthwhile goal. Having a LW community with is powerful to be a stakeholder with certain power is a worthwhile goal.

If you invest your money into the startup that your fellow LW community member wants to start instead of investing it into an index fund, that makes the LW community strong. Less money in the stock market in turn makes big corporations weaker.

Reallocating your investments isn't attacking the mainstream. It's focusing your resources inside your own community.

Investing your money with fellow rationalists might be an even better return on your investment than an index fund but that isn't the only point. Where you allocate your retirement money is a political question that more important as to how you vote in elections and whether corporatist party A or corporatist party B holds power.

I do in fact not have money in index funds, or any other Wall Street related investment. And I try not to support social structures I find abhorrent, occasionally as relatively significant personal cost.

However its my position that attacking the status quo is necessary, although what you suggest is also necessary. I don't think its a one or the other thing.

I think that one of the core problems is that too much people watch TV to inform themselves of what's important and have money where it empowers the SAP 500 companies.

Going around and arguing at parties that the other people who attend should stop watching TV and invest their money outside of the mainstream isn't what most people imagine when they speak about attacking the status quo.

I think the core issue is moving from a spectator who watches TV and who hopes that the index fund over which he has no control will do well to moving to being an actor. To the extend that you yourself made that step, it's to convince others to follow yourself. That doesn't mean not going to parties with mainstream folks. It doesn't mean getting angry at them. It means talking openly with them about the choices they make in a way that doesn't get you kicked out of the party.

I think that's a much more effective strategy than going out demonstrating.

There are times when it makes sense to interact within the system. If you care for media you might find my exchange with mbitton24 in his thread "Some Tools For Optimizing Our Media Use" interesting.
