Is it possible to tame an octopus? Could humanity over several generations tame octopuses and breed them into work animals?

Bonus Stupid Question

I remember reading about how some biologists took some wild foxes, and allowed ones which were friendlier to humans to breed. In the next generation of fox offspring, they let the friendliest ones of those litters reproduce. They repeated this several times. After some number of generations, they found these friendliest of foxes had droopy ears like domesticated dogs. This demonstrates how a simple process of artificial selection, like just selecting for friendlier animal companions, may have been sufficient to lead to the domestication of dogs.

Now, my question is, could we humans do the same thing with octopi? Could we just take a population of octopi, and identify the ones which can meaningfully interact with humans in a friendly and docile way, and let them breed, and iterate this process until we have some kind of domesticated octopi?

If they're not long-lived, they wouldn't make good work animals, but I want to know if octopi could at all be domesticated regardless. The fact they're short-lived might mean humans could breed domesticated octopi even faster.

I imagine a lot of the selection was indirect selection for neoteny. I think it would be much, much harder to select for domestication in octopi, as they do not raise their young.

I'd speculate that if you did an identical breeding experiment with octopuses (as in, the breeding criteria of non-aggressively interaction with human hand) you'd breed for curious, bold, or playful octopuses which tend to approach novel stimuli ... but not friendly in the sense of affectionate.

It's not that they're asocial, I think they sometimes lay eggs cooperatively and obviously seek each other out for mating... but primarily octopuses see others of their species as predators or prey. (I mean, cats do eat each other but only in bounded contexts, like infanticide, not hunting.)

Octopuses / octopodes. It's greek, not latin.

Or could we breed them for intelligence...? With such short periods between generations, we could reach superintelligence, maybe faster than other methods!

I would imagine that using foxes give you a lot more to work with though. Foxes in nature live in pairs or small groups. The children stay around the parent for a long time. So they already have mechanisms in place for social behaviours. (And even if they are not expressed, there probably are some latent possibilities shared among mammals? E.g. this article about the evolution of housecats notes that they independently evolved a lot of the same behaviours that lion prides use to socialise, even though wildcats are solitary.)

comment by Tem42 · 2015-08-05T03:14:14.540Z · LW(p) · GW(p)

It is not hard to tame them and train them, but I have not heard of anyone training them to do something that is functionally useful aside from the narrow area of octopus-keeping. They have been trained to get into a bucket for easy transportation, to climb out of the water and interact with their keepers 'politely', and, famously, to take photos of aquarium goers. Bus as far as underwater rescue, exploration, or hunting for artifacts, AFAIK this has not been done yet. But if for some reason we needed them to run an underwater maze -- easy!

comment by Sarunas · 2015-08-03T21:36:08.141Z · LW(p) · GW(p)

Octopuses are solitary animals, whereas most working animals are social. Which leads to another interesting question - is it possible to breed octopuses to become social animals?

Dunno - it worked with house cats, which are far more social than their wild ancestors, although not as social as lions. (Wild cats will not share territory with others, even when food is plentiful. Feral cats will live in feral cat colonies around food sources.)

Octopodes use hemocyanin... use CRISPR to take that out, lenti vector to replace with hemoglobin, and you've got a super-octopus.

Now just apply MIRI's magic formula for making friendly superintelligence, and you've got your tame octopus. Great basis for a TV show in the genre of "Lassie", "Flipper", or "Skippy the Bush Kangaroo".

"Good on ya', Cthulipper!"

Octopuses have poisonous bites, of course.... some would see that as a bad quality in a pet.

I was recently at a bar with some friends, most of which are from the same physics PhD program as me. We had a discussion about how hard it is to spend all your time around unusually intelligent people, and then go out into the real world and have conversations with normal people. It seems to be intelligence-related, because it's usually much easier to have a conversation with, for example, a psychology grad student from Singapore than with a fashion designer who lives in the same city as me.

Is this just because we have no practice talking to people of average-ish intelligence?

Is it because intelligence gaps are inherently difficult in social settings?

Is there some factor other than intelligence that's causing this?

Are we just socially inept?

(Is this more of an open thread question or stupid question?)

I think this is mostly a function of the subculture to which you belong and, specifically, which things you find interesting, exciting, important, etc. IQ, of course, is a major underlying factor, but it's not just IQ.

Each subculture also has its own social rituals and implicit communication methods so when you cross over to a different one you are very likely to have conversation difficulties -- unless your social skills are highly developed and you have some idea about how that subculture works.

This was my first thought, too. The Singaporean psychology grad student is a member of the same culture as you; the local fashion designer is not.

I believe a lot of practice would make talking to people with average intelligence easier. Not necessarily more satisfying, though. You will always have to debate with them at their level, while you probably enjoy debating at your level.

Is it because intelligence gaps are inherently difficult in social settings?

Could be. We naturally model other people by imagining what we would do in the same situation. If you use this algorithm to model people with much lower intelligence, you will get many predictions wrong.

Is there some factor other than intelligence that's causing this?

Sure. Rationality, culture, past experiences. All of these make modelling each other more difficult.

Are we just socially inept?

Possibly; but what exactly do you mean by "inept"? Unable to learn? -- probably not. Haven't learned yet? -- probably yes. The question is whether learning "how to communicate with normal people" is the best use of your time.

Not all talking is debating.

I'm an economics professor at a good college. A fair number of my students are interested in fashion and have written on the topic for one of my "apply economics to anything" paper assignments. Fashion is a deeper topic than you might imagine and can justifiably attract bright minds.

Prediction: A typical fashion designer and physics PhD get into a conversation. If the fashion designer wanted the PhD to greatly enjoy the conversation she could easily do this (even without doing anything sexual) but the reverse probably doesn't hold true.

I didn't mean to suggest that being in the fashion industry implies that someone is unintelligent. I've known plenty of smart people in industries that are not traditionally thought of as being full of smart people. For this reason, I usually approach a conversation assuming that someone is good at something they do, has thought about it deeply, and has something interesting to say about it. It's usually much easier for me to tease this out with smarter people.

comment by Elo · 2015-08-03T05:51:47.077Z · LW(p) · GW(p)

Is this just because we have no practice talking to people of average-ish intelligence?

We tend to get used to (read: lazy in a system 1 time-saving way.) the systems we are regularly engaged in. i.e. I don't often talk about the weather (and other small talk) with people of higher intelligence (unless in a meta-sense). So I sometimes feel off-guard when trying to respond in the "normal" way that people do.

Is it because intelligence gaps are inherently difficult in social settings?

I usually appeal to stereotypical behaviour where there is common ground. For example - "growth mindset vs fixed mindset", The last time I talked to someone in the fashion industry I equally had a "black box" discussion, and found the bad communication experience too. But then I went on to talk about how I don't know because I had never ever gotten into it, and asked them to "teach me everything you know", which is a way to stump them back in the other direction. At the very least it get's people thinking, at the most you might get the opportunity to learn, they might get the opportunity to think, and you establish a new connection with someone you didn't think was interesting.

Is there some factor other than intelligence that's causing this? Are we just socially inept?

There is something called "social intelligence" which you might not be optimising for. Which is completely fine, but can cause this sort of experience to happen. I have personally recently decided to invest more in social-intelligence. The main take-away from that concept is that there are only so many hours in the day. If you want to expend 100 hours on social intelligence learning, that's 100 less hours on learning programming or tackling UFAI, Or learning about music, fashion, communication, art, biotechnology, medicine, law... There are many things that people find valuable. Not everything is universal. I would consider social intelligence as a meta-skill, in a similar way to improving your memory, increasing your sleep quality, learning to communicate in another language, and 101 other things.

It's up to you whether you want to pursue social intelligence.

An excellent question! I have now written a meta document of "How do I learn X" which I have sent off to a friend to be checked before I post it on Lesswrong. I will post a link (probably in the next 24 hours) to a discussion thread. I think the meta-strategy is going to be more helpful and for more people. I can write a specific list after.

As a teaser:

  1. Make a list of your knowledge in the area
  2. Confirm what you think you know (via brief research), replace your existing knowledge with correct knowledge.
  3. Make a list of the topics of knowledge in the area.
  4. spend time finding the best resource (as a trade off of searching-time, $cost, time-to-cover-the-resource)
  5. delve in, absorb the knowledge
  6. devise ways to test yourself, and/or experiment that you have gained the knowledge. (experimental methods include controlled environments, repeated tests, evaluation)
  7. teach others in order to cement your knowledge.

This list is a teaser; there are more points, but you can probably cover 1-3 by the time I get to publish the list.

What do you mean by "hard"? Difficult? Frustrating? Boring?


I don't think that intelligence itself it causally related to any of those 3 things.

  • You could be "intelligent" and have "social skills".
  • You could be "intelligent" and not be frustrated by normal people. Maybe you're a huge humanist who just loves people so much. Maybe you don't view normal people as being at fault. Maybe your expectations are low for a number of reasons.
  • You could be "intelligent" and find normal people enjoyable. You probably wouldn't get to be intellectually stimulated by interactions with normal people, but you might... enjoy the "mere exposure" (humans enjoy socializing), enjoy goofing around, enjoy teaching them, enjoy their kindness, enjoy observing them as a means to better understand cognitive psychology.

My guess is that intelligent people...

  • Who spend a lot of time in a certain in-group might "forget" what the norms of other groups are like. I mean "forget" in a "procedural" sense rather than a "declarative" one. A lot of times you might just acting according to the norms you're used to out of habit, but then realize, "oh yeah, normal people don't do this".
  • Intelligent people (feel that they) understand that and why a lot of the things normal people do aren't rational. I think that given a "default" perspective, this is very frustrating. But given a different perspective, it isn't necessarily frustrating (I'd love to hear more about this perspective...).
  • Intelligent people seem to be somewhat socialized to think that "normal pleasures" are sort of... "lesser". And so they don't derive as much joy from them, and instead need a certain amount of intellectual stimulation.

What do you mean by "hard"? Difficult? Frustrating? Boring?

For a variety of reasons, I'm hesitant to share a specific example, but here is an exchange from the conversation I had recently:

Me: To me, the fashion industry is this black box that has people in it, and clothing comes out of it

Her (surprised, confused): It's not like that at all!

Me: What I mean is that I don't know anything about how it works, except that it involves people who design clothing, and then somebody buys it

Her (still confused): Yeah...

<at this point I decided trying to get her to tell me about it wasn't going anywhere, so I moved on to attempt at embarrassing my friend who was standing nearby, who then got lots of unwanted attention from her>

So I guess it's mainly frustrating or boring?

That might be understood as you expressing that you consider the fashion industry low status with a challenge for her to prove otherwise.

<at this point I decided trying to get her to tell me about it wasn't going anywhere, so I moved on to attempt at embarrassing my friend who was standing nearby, who then got lots of unwanted attention from her>

The straightforward way to get her to tell you something about the fashion industry would be to ask her a question about it. You didn't.

Most people in parties don't focus on exchange of information. If you are talking to someone who thinks conversation is about finding a topic where meaningful information can be exchanged the purpose of your remarks is more obvious than if you are talking to someone who has other goals.

Hahahaha, that's really funny! "It's not like that at all" :)

My understanding is that the black box analogy is understood by some normal people, but not most.

How could you have made for a more enjoyable interaction? Some thoughts that come to my mind:

  • (Meta level: What's my goal? Enjoyable conversation? Where do our interests overlap? I like to have interesting conversations. She's probably not very smart, so her ability to have interesting conversations is probably limited to her domain. What interesting conversations could we have within her domain? What thoughts do I have about her domain? What are the likely ways she'd respond to those thoughts? Alternatives: skipping shallow talk and talking about emotional things is probably enjoyable. For some reason humans enjoy sharing their feelings. What's the line between interesting and creepy? Are you happy? What are your ambitions? What would you do if you didn't have to work?)
  • Our society's fashion seems really dark. Dark blues, blacks, browns, greys etc. I think it'd be cool if there were more color. I like to wear colorful clothing, but don't really. Mostly because it's more difficult to pair things up and I'm lazy. Which would lead to her probably giving advice, and maybe talking about color in a historical sense. Was it more colorful in the past? Will it be in the future? On that note, are there any trends in color? What about across cultures? Do any consistencies across culture say anything about design/color and human nature?
  • Maybe once she's been loosened up, I'd comment on how I love wearing pajama pants. Plus some stories of that. And my thoughts on how society seems to have chosen pretty uncomfortable clothes as its norms. There's probably nothing inherent about suits and khakis and jeans that look good. If we all agreed that something more comfortable was the new norm, we'd probably be better off. (Pet peeve: the "shoulder pads" on suits are just ridiculous. You can't even lift up your arms!) I wouldn't open with this though; it'd probably be seen as too controversial and weird right away. But it might be fun/funny once the person's been loosened up.
  • People who otherwise aren't intelligent often have somewhat smart things to say within their domain. So maybe you'd be able to have some sort of enjoyable conversations with her about fashion, and maybe she'd enjoy the cognitive psychology topics/spins.

Yeah. One more thing - in some ways I'm a bit egocentric. So my instinct is to think about the thoughts that I have on the topic and discuss them (I tend to have a lot of thoughts about a lot of things. Or at least a lot of questions.). I notice that I didn't think too much about the strategy of evoking her strongly held opinions. But something about my more egocentric approach of pursuing lines of conversation that interest me feels more... natural/genuine, which I think often leads to good.

(Not that I've had much success. I've always done well in "natural" conversations and am outgoing, but I've never been motivated enough to overcome the awkwardness of initiating conversations with random people out of nothing.)

I will admit that when I wrote that, I was going off of blurry memories of seeing test scores. I will also admit that I kind of regret introducing the topic the way I did. I wanted to convey that I was comparing people who were both similarly removed from me culturally, but were from populations that would generally have different average intelligence from each other.

In that description, I was referring to literally just "some person who said they are in the fashion industry". This includes fashion designers, accountants, HR people, photographers, janitors, (materials engineers? computer graphics engineers?) etc. But sure, let's go with fashion designers.

Using IQ <==> SAT/GRE conversion tables, if you look up test scores for entering visual arts majors (I think that's what a college-educated fashion designer would study?), they average about 115 IQ, whereas GRE scores for entering psychology PhDs predict about 125-130 IQ (this one's hard, because I can only find "scaled" composite scores, rather than raw composite scores). This is about a one standard deviation difference.

I mainly believe in using SAT and GRE scores as a proxy for IQ because Scott Alexander believes in this enough to pay attention to it on the LW census. Also, I have skimmed some literature on it. I've not examined it carefully, and I'm interested to hear dissenting opinions.

This seems like clear evidence that your average college-educated fashion designer has a higher than average IQ, by a full standard deviation. Evidently, your average psychology PhD student (at the two competitive schools I looked at) has an IQ nearly a full standard deviation above that. Although what I said looks like the kind of thing someone would say if they thought fashion designers were stupid, that wasn't my intent.

There are a few case studies/papers arguing it might help. It seemed to help one guy trying an RCT but the temporal patterns were weird. It didn't do me any harm; on the other hand, I didn't notice any benefit and the initial benefit seems to have been a selection/confounding effect since it disappeared after randomization.

I guess it depends on how much of your time/energy you think 10 minutes usage will cost you and if you think it's worth a shot.

I work with infrared lasers, and the main safety advice I will give you is that 850nm light will look very dim, even if it is very bright. So be careful about shining it in your eyes, because how bright it looks is misleading. That said, it does take a very bright source of visible or IR light to actually damage your eyes.

After trying to imagine a way this would fail badly, I think you should make sure that whatever you do, you can remove it quickly. It's common for homemade electronics to get hot or catch fire, and you don't want to have any trouble getting if off your head if that does happen.

No way to know unless you measure its output spectrum, but as long as it's mostly IR, it shouldn't.

Biohacking self-improvement light therapy supposedly to reduce inflammation. It has an immediate and noticeable effect on me, strong enough that I doubt it's just placebo. It started when I suffered long-term low-level pain in my ankle several months after twisting it (I hate aging!), and read how light exposure at the right wavelengths could help. My ankle did improve, although of course this might have been just natural healing. Then I started to consider other possible benefits of light therapy such as reducing inflammation in the brain.

I have very high prior against light therapy on forehead or scalp reducing inflammation in brain. There is thick bone between skin and brain! Blood supply to skin on head is separate system to blood supply to brain. Maybe beneficial effect on skin, creates healing particles in blood, blood carry them to brain. But have to go long way round. Also cross blood-brain barrier.

Phototherapy for SAD is different, more plausible, because proposed mechanism is direct via photonic stimulation of retina to influence biorhythm-generating processes. Signal passes in to brain by nerves, not blood.

But rigorous self-experimentation is good idea with low-risk treatment. So I wish you good luck even though I count low chance of success, except for placebo effect.

Mostly because "we" are young -- the median LWer aged between 25 and 34 makes more money than the median American in that age range, and the median American LWer in that age range makes even more, but only 50% of LWers are older than 26 and only 25% are older than 31.

1) Because getting rich is pretty hard.
2) Because we haven't been trying all that hard.

Most people who get rich probably got there in one of three ways:

1) Be born with rich parents (or other relatives)
2) Marry someone who's already rich
3) Enter a career path in which it is possible to make lots of money, then be successful enough in that career path to become rich.

My brother did #3 - he won the Goldman Sachs internship lottery, got hired into a permanent position, then, a few years later, jumped ship to a hedge fund that offered him more money than his boss was making. (He even took every one of his co-workers at his trading desk with him, much to the dismay of both his boss and his boss's boss.)

I've not made the attempt. My brother worked his ass off in a way I don't want to duplicate, and it's perfectly rational to decide that there are more important things in life than the expected size of one's paycheck. ;)

Does modafinal literally eliminate akrasia for you? I need to get me some of that.

I think that was one factor Yvain mentioned. The other two I think are more damning to the whole idea of rationality as winning.

One is that most people who are successful are rational when they need to be in their field, without having to make a formal study and be rational all the time.

The other idea is that rationality is only a small small slice of what makes you successful, and that there are probably a ton of other factors that help even more.

One idea that Yvain didn't mention (and actually wrote a blog post arguing against) is that maybe rationality is a red queen game. The more you study it, the more tricky your mind gets at rationalizing it's irrationalities. That view is explored here: http://www.overcomingbias.com/2014/06/bias-is-a-red-queen-game.html

Speaking only from personal experience, it reduces akrasia rather than eliminates it.

An odd factor is an inability to engage in pure entertainment, but I wonder if this is merely a latent psychological issue specific to me that only surfaces when taking modafinil. This seems like it's a benefit, but it can be an annoyance in regards to social interaction, almost like a classic djinn wish. Since it only lasts half a day (for me) after the first week, this isn't really a problem, though.

I recommend never taking anything with caffeine in it while on modafinil, but you might not respond as strongly to it as I do.

The most easily observed benefit for me has been not falling asleep while driving, watching movies, sitting, standing idly, etc.

Yeah, that makes sense... I certainly know people that have spent a LOT of effort maintaining their randomly chosen viewpoint. Goes back to meme theory, memes are selected for ability to stick in the mind and remove other memes.

I agree with everyone else: LW skews young (also researchy; not many PhD students are rich) and many LWers care more about other things than about getting rich, and in fact the LW population is wealthier than you would expect from age alone (though I don't know how it compares with what you'd get if you looked at, say, age, family's socioeconomic status, and IQ).

I'd add: getting substantially rich takes luck as well as skill and hard work (some rich people will claim otherwise -- but they would, wouldn't they?).

comment by MrMind · 2015-08-10T09:38:11.012Z · LW(p) · GW(p)

Becoming rich is a matter of:

  • caring about money enough to devote a substantial amount of time to the task;
  • a specific financial education;
  • discovering a profitable career / market niche.

I've listed those in the order I think they pose an obstacle to LWers.

comment by Dorikka · 2015-08-10T03:31:53.679Z · LW(p) · GW(p)

As an off-the-cuff thought, much LW-content is useful for determining values and bringing strategies in alignment with those values. (I think of a hierarchy: values->strategies->campaigns->goals->actions.) It's also useful for some bug-catching and as some general tools of thought, but amassing lots of wealth is a convergent instrumental goal of many, many value setups. So value-discrimination may not really affect that, since either set of values would lead you to amass wealth.

The above isn't really something that I'm confident of, and belongs in the "only posted because the alternative is not posting" bucket.

Apparently the Crips gang was started as a neighbourhood watch against criminals. I'm interested in how violent groups are formed - paramilitaries and such. Anywhere where I can read more on the topic? A wikipedia article for instance. It's fascinating how someone can take a non-violent group and make it violent - I suppose there is research on the tactics - scapegoating and what not. From every field from how Jihadis are radicalised, to socialists and turned into passionate revolutionaries.

Hello. I am a young man about who's quite worried about Ai, like many here, and I'd like to know if I could help in any way.

I can't donate much money, at least not for a few years, and from reading So8res' recent post, money won't be much of an issue in a few years.

However, I am fairly intelligent, and I think I could help a little research wise. Of course, after a few years of rigorous study.

But there are many people at least as intelligent as I, so perhaps my trying to help wouldn't make any difference.

The issue is, I'm in no place to know. If someone out there is working in the field and comes across this, please advise me on what to do. Should I study hard and try and help a little, or would going down this path be fruitless?

My opinion is that the vast majority of smart people in rich countries can do the most good for the world by "earning to give" and seeking to earn a high salary and giving some of it to carefully chosen charities. If you have the math skills to become a physicist you might be an exception, especially if you can be of direct use to MIRI. My impression is that outside of academia some physicists earn high incomes, so you might want to consider that path.

Suppose a research team works on the methods comparability issue. (Specifically, 'is it possible to compare the percent of fungal colonization [the length of roots occupied by fungus divided by the total length of the root system], obtained by using Technique A [staining with fuchsin] with the figure for Technique B […Trypan blue]? For further specifics, see Gange et al, 'A comparision of visualisation techniques for recording arbuscular mycorrhizal colonisation', although I promise it is not required for this SQ.)

The problem with both Techniques A and B is that different researchers' estimates may vary plus minus 10% (for the same slide). The team, aware of that, assigned just one, experienced member to the recording part, and I think doubled the sample (the number of viewed fields of vision per slide). They showed that the figures for A and B can be about 20% different.

If I have to guesstimate how my own results for a different set of roots of the same species of plant can be compared with somebody else's, and I use A and he uses B, do I have to allow for a possible 40% gap of total variation? Because that would make it a bloody useless comparison...

Suppose I do a similar methodology study myself, and I can ask a (even less experienced partner) to score all those fields of vision that I view myself, would our composite estimates for A and B be more, well, robust than if I did it alone? It seems so, but then again, maybe it is better if she scored different fields of vision on the same slide. I am confused.

There is a variable X, x belongs to [0, 100]. There are n ways of measuring it, among them A and B are widely used. For any given measurer, the difference between x(A) and x(B) can be up to 20 points. Between two any measurers, x(A)1 and x(A)2 can differ on average 10 points, likewise with B.

Measurer 1 wants to know if it is meaningful to compare her results, x(A)1, with Measurer 2's results, x(B)2. Does the interval in which the true x lies include 40 points?

If Measurer 1 herself establishes the difference between x(C)1 and x(D)1, where C and D are two other ways to measure x, how much more useful for any given Measurer 3 will be her results, if she also invites Measurer 2's opinion - that is, x(C)2 and x(D)2?

Factor analysis/measurement error/multilevel models/Value of Information: X is a latent variable, which yields more latent variables (one for each kind of method), which are themselves measured with error by the raw datapoints. So you have multiple kinds of measurements, each with their own error, giving you a multilevel model. You can write a multilevel model expressing this in a Bayesian language like JAGS or you could use a SEM library like lavaan, where it'd be something like 'x ~ A, x ~ B, A ~ a-datapoints, B ~ b-datapoints'...

(To give an analogy: imagine you are measuring Gf. Gf is a latent variable which is predicted from things like WM or executive function; WM and executive function are themselves latent variables, which are measured by tests like forwards digit span. The graph would look like a little pyramid. So you measure someone's intelligence by doing forwards digit span several times, giving you a reasonably precise estimate of the latent variable WM, which then gives you a imprecise estimate of the highest latent variable Gf.)

Measurer 1 wants to know if it is meaningful to compare her results, x(A)1, with Measurer 2's results, x(B)2. Does the interval in which the true x lies include 40 points?

Comparing measurer 1 and measurer 2's results is not really the same thing as simply asking for the posterior distribution of the latent x, but yes, with the posterior, it's easy to calculate the probability of anything you like such as '>=40' or '<=90'.

If Measurer 1 herself establishes the difference between x(C)1 and x(D)1, where C and D are two other ways to measure x, how much more useful for any given Measurer 3 will be her results, if she also invites Measurer 2's opinion - that is, x(C)2 and x(D)2?

I only know a Bayesian approach here: it sounds like Expected Value of Sample Information. You need a loss function on error (mean squared, perhaps?) and then you can repeatedly sample from the posterior based on all of Measurer 3's data as a hypothetical, and then look at how much loss is reduced based an additional sample (or more) from Measurer 2.

(You could always go ask the Statistics Stack Overflow.)

Thank you! (In part, for such faith in my abilities:) Have to go hunt myself a programmer for dinner...)

It seems that if M-r 1 gives M-r 2 the same subsample of the middle latent variables (photoes of fields of vision, scoring them gives you the datapoints), and the x1 is compared with x2, they can see the least difference between them, which is (largely?) sample-independent. If, however, M-r 1 and M-r 2 each draw their subsamples independently, the difference between x1 and x2 should be larger due to chance, right?.. So if we look at the difference in differences between x1and x2, and it is greater for some middle latent variables (ways of staining) than for others, can we use it as a measure of 'the overall variability of the measuring method'? Say, if we have ten measurers and four measuring methods...

(I'm asking you this because it is relatively simple to do in practice, not because I think this would be the most efficient way.)

You can estimate the bias of each measurer much more efficiently if you have them measure the same sample, yes, analogous to crossover: now the differences are due less to the wide diversity of the sampled population and more to the particular measurer.

(To put it a little more mathily, when each measurer measures different samples, then the measurements will be spread very widely because it's Var(measurer-bias) + Var(population); but if we have the measurers measure the same sample, then Var(population) drops out and now there's just Var(measurer-bias). If I measure a sample and get 2.9 and you measure it as well and get 3.1, then probably the sample is really ~3.0 and my bias is -0.1 and your bias is +0.1. If I measure one sample and get 2.9 and you measure a different sample and get 3.1, then my bias and your bias are... ???)

For example, the classic example for MLMs is you have n classrooms' test scores, and you want to figure out the teachers' effects. It's hard to tell because the classrooms' average scores will differ a lot on their own. This is analogous to your original description: each measurer gets their own batch of samples. But what if you had a crossed design of one classroom with test scores after it's taught by each teacher? Then much of the differences in the average score will be due to the particular effect of each teacher and that will be much easier to estimate.

So if we look at the difference in differences between x1and x2, and it is greater for some middle latent variables (ways of staining) than for others, can we use it as a measure of 'the overall variability of the measuring method'? Say, if we have ten measurers and four measuring methods...

I guess. From a factor analysis perspective, you just want to pick the one with the highest loading on X, I think.

I don't really understand the problem. Yes, maybe you can't control them and get everyone onto the same method page. But I've already explained how you deal with that, given you the relevant keywords to search for like 'measurement error', and also given you example R code implementing several approaches.

They all take the basic approach of treating it as data/measurements which load on a latent variable for each method, and each method loads on the latent variable which is what you actually want; then you can infer whatever you need to. The first level of latent variables helps you estimate the biases of each category, some of which may be smaller than others, and then you collectively use them to estimate the final latent variable. Now you have a principled way to unify all your data from disparate methods which measure in similar but not identical way the variable you care about. If someone else comes up with a new method, it can be incorporated like the rest.

1) I have too many goals, and so I don't know how to properly prioritize them, making it difficult to choose a next task. 2) Once I try to prioritize goals I end up going down a black hole of trying to figure out what my values really are, what I should actually be doing with my life, what I actually care about, if moral philosophy has implications on my goals, etc etc etc until I've either wasted all of my free time or ended up with an entirely new set of goals.

My stupid question is, does anyone else relate to this? How do you manage to not get caught in "analysis paralysis"? Do I have the entirely incorrect approach to life by trying to base my moment to moment actions on an overall value system?

Oh yes, I certainly do.

How do you manage to not get caught in "analysis paralysis"?

I do not, for the most part.
On the other side, it's a matter of understanding that ultimately, nothing has an absolute value, so you can as well do entertaining things. Or creative things. The universe won't care anyway.

Do I have the entirely incorrect approach to life by trying to base my moment to moment actions on an overall value system?

Of course, since the system needs to compress so much information that updating it is a momentous and futile task. More so if its purpose is to guide your actions.
Better to start with a very imperfect value system and update it slowly on the run.

I'm trying to iron a 100% cotton men's dress shirt. I iron one section until it looks wrinkle-free, then I iron another section, and then I look at the first section and it's wrinkled again! What am I doing wrong and how do I fix it?

You might be ironing the parts in the wrong order, or getting the freshly ironed part under something. But the first thing I would try in your position is to just iron every part of the shirt and hang it up for a while, and then see if the wrinkles go away again. Often wrinkles that come about right after ironing are much softer than the ones that you remove by ironing.

One right order is: Collar, yoke, one arm [cuff first], other arm [cuff first], front left, back, front right.

Are the wrinkles pretty much the same ones you started with, or are they new ones with sharper creases?

If new, sharp creases, you are probably accidentally ironing creases in the wrong place, or folding it over as you go. Concentrate carefully on the placement of the garment, remembering that fabric will remain prone to creasing while it remains hot.

If original wrinkles which have not gone away: You are probably not using enough heat and steam. 100% cotton needs pretty much as hot as the iron will go (>=3 dots), and as much steam as the iron will produce. Consult the manual (!) for how to ensure the iron is producing copious steam. Typically, you need to put enough water in (not too much), have it set to a high enough temperature, set the steam control valve to maximum, wait for it to heat up to hot enough.

My guess is not enough heat and steam.

Beware! An iron this hot will melt many other garments. But a colder iron will not be effective on 100% cotton. Linen needs a lot of heat too. Look on the care label for an iron icon. The number of dots indicates how hot your iron should be - 1 (coolest, garment at risk of melting if iron set higher), 2 or 3 (hot, garment at risk of not de-creasing if iron set lower). Hotter irons are more effective (speed and quality of output) than cooler ones. In my experience garment manufacturers set the care label conservatively and you can get away with a setting one higher most of the time. But always test carefully first.

I love that LW has people publicly advocating for all sorts of fringe positions -

(Someone once commented that in one thread we'll describe common persuasive techniques as "dark arts", and in the next thread we'll bemoan that cutting off heads and freezing them so we can perform necromancy isn't more popular.)

- and someone is using the community throwaway account to give advice on ironing.

(I recognise that it's probably more "don't want to make an account" than "don't want to be identified". But still.)

Why do politicians bother with such offputting political ads?

Posting this in the stupid questions thread because it's unclear to me why obvious question is not, for the most, raised or answered elsewhere.

Requests For Intelligence Information

Political campaigning is expensive. I assume it takes up a large portion of political party's campaign funds. But what if (some of it is) a waste of time, or even counterproductive? If that was the case, as I have reason to believe (follow my links). If that's the case, political entities have reason to spend less in order to push their cause. If they need to spend less, there is less incentive to solicit funds from sources that may have undue influence over them leading to poorer public perception, or corrupt behaviour.

It is not public knowledge how the major Australian political parties assess their marketing effectiveness. They don't use the marketing evalution tools taught in marketing classrooms for the business world and academic studies on effectiveness are decades old, foreign or non-existent. The evidence that does exist, suggests that [most political advertising is a waste of time, except doorknocking. This suprises me, since it would piss me off if an average unelected candidate came to my door. Surveys of trusted political party members from both the Liberal and Labour parties suggests that ordinary members, including those active in subcommittees and minor official positions don't have access to this information. I expect that it is held either by:

a) external political consultants

b) senior party officials

c) elected party members

d) elected party member staffers

e) branch level marketing officials

f) unknown other categories

g) some combination of the above

This post is a call for information to fill in this knowledge gap. If you have any relevant intelligence, feel free to comment. If you have any relevant intelligence that you would like to have shared while preserving your anonymity, you can message me with it and I will post it here on your behalf without your username and reject any requests for identifying information about you should that case arise. If you have relevant intelligence and would not like it posted, I would still be interested to know privately and encourage you to contact me with it.

In many political systems, a major intention of campaigning is to attract news coverage, not to influence voters directly.

In some cases, being off-putting is the goal. The more you can make potential voters disgusted with the political process, the more likely they are to stay home and not vote. If you are a party that has a base that votes a lot, and your opponents have a more fickle voter base that are more likely to stay home instead of voting, icky political ads serve your purpose.

Given that Western political systems are basically a Darwinian selection process, I would be greatly surprised if the political consultants didn't have a good idea about the effectiveness of their propaganda. They certainly gather and examine the data. Of course, there is not much incentive for them to publish their results.

Do you have any reason to believe that political consultants are particularly stupid?

Political consultants make money by convincing politicians that they are useful, not by actually being useful.

I have no idea which of the below are true, or to what extent: 1) They're not off-putting to everyone; you are not the target audience 2) Being off-putting is valuable, as decreasing voter turnout benefits their strategy 3) Being off-putting does not matter, as they remain effective regardless 4a) No one is checking if these are effective 4b) The people who DO check if these are effective have a vested interest in showing they are

If no one is gathering data on the effectiveness, then the next best strategy is to copy your competitor.

Apparently since the Enlightenment this idea has gotten about that all the previous generations didn't know how to live properly, even our parents' generation; but that we somehow mysteriously know how to do it right, or at least better. But then if we have offspring, many of them might develop the same attitude towards us.

This really doesn't make sense, because incompetent people generally don't leave descendants. Our ancestors must have gotten a lot of important things right on average for us to have come into existence in the first place. Yet we think we can just reverse the wisdom of the ages in all kinds of areas and not screw things up. It looks like a kind of evolution-denialism, in fact.

How can people who say they believe in evolution also hold the conflicting idea that they know better than the principles derived from the collective evolutionary experiences of human survival?

The criticism tends to be that people were too mean rather than that they were incompetent.

Has it? That rather sounds like a crotchety old guy's notion about Kids These Days, and as far as I know old people only got that crotchety after 1950 or so (tongue-in-cheek).

Evolution works in the timespan of hundreds of generations or more. A cultural or political trend can wreck a society in a few generations, before evolution has any time to compensate.

There's lots of systems which exist, but don't deliver my preferences and goals. I find it extremely likely that know what I want and how to get it much better than a semi-random offspring filtering process.

As far as I can tell, in postmodern western value systems the idea isn't that they know better than Gnon, it's the idea that "principles derived from the collective evolutionary experiences of human survival" shouldn't matter in comparison to postmodern cultural sensibilities, and therefore it's worth expending effort to counter them as opposed to making use of them.

Most people don't consider the goal of life to be maximizing the amount of offspring.
