I recently had an idea that seemed interesting enough to post here: "Shut Up and Multiply!", the video game

The basic idea of this game is that before each level you are told some probabilities, and then when the level starts you need to use these probabilities in real time to achieve the best expected outcome in a given situation.

The first example I thought of is a level where people are drowning, and you need to choose who to save first, or possibly which method to use to try to save them, in order to maximize the total number of people saved.

Different levels could have different scenarios and objectives.

You are given time to examine the probabilities before the level starts, but once it starts you need to make your decisions in real-time.

Another twist: You see the actual outcome of your actions, randomly generated by the probability formulas. However, you aren't scored based on the actual outcome, but instead you are scored on the expected outcome of your actions, using the expected utility formula. I originally intended this to prevent people from getting a high score just by luck, or to prevent low scores caused by bad luck. Though I later realized that this doesn't actually fix the problem - you can still play repeatedly until, by luck, you happen to guess high-scoring actions. Still, I think it would be a good idea to show both scores.

Other random ideas:

The first few levels should be a tutorial. Showing how to do the calculations in order to maximize your expected score. Or there could be a separate turotial mode. Or maybe the game itself is a bad idea, but the tutorial might still be useful.

During each level you need to make your decisions as quickly as possible - the longer you wait the worse you score. Though maybe only some levels should be like this.

Later levels require more options to choose from, and more complex scenarios.

As much content as possible should be generated randomly, to prevent the game from being the same if you play it again.

Maybe the player could also be scored based on some calculations they do before the level starts? Or just integrate this with the tutorial?

And most importantly: Specifically design the game so that the player must learn to overcome some of the standard biases, in order to maximize their score. We should try to work in as many of these biases as possible. And also plenty of generally useful advice for working with probabilities.

So, now that I posted this idea, I'll let you decide what, if anything, we should do with this idea.

First, is this a stupid idea, that couldn't possibly work as described?

Or is it a good idea, but a low priority, compared to the other projects we're working on?

Should this be a group project? Does anyone volunteer to lead the project? Does anyone want to take on the project entirely on their own? Or should I lead the project, or work on it on my own?

What language would be best to implement this in? Flash? Java? PHP? Python? Something else?

I still haven't earned much karma on this site (only 1 point actually, when I originally posted this). Mainly because I don't expect to have anything original to say. And so I'm posting this here as a comment in the Open Thread, rather than making an actual post of it. If this comment gets enough upvotes for me to be able to make this into its own post, I plan to do so, unless someone objects. Or if anyone would like to take over the idea, please feel free to do so. I don't care about credit, and generally prefer to avoid it. Possibly by the flawed reasoning "credit = responsibility = blame", which I suppose might deserve a post of its own.

I'd suggest making it so you get scored by the number of people you save, but the game is long enough that luck doesn't make a difference. I wonder if it would be a good idea to give it multiple scores. For example, lives saved, life-years saved, quality-adjusted life-years saved, etc.. This way, you won't have as many problems with people disagreeing with the scoring system. Alternately, you could just have it so you could change the scoring mode in the options part. It would also act somewhat as a difficulty setting. It would get harder when you have to weigh a destitute child, who will live longer, vs. a middle-class adult, who will be happier.

Reading that, it occurred to me that in all the computer games I've played, it is possible to totally succeed. Kill every monster, pick up every piece of treasure, solve every puzzle, gain the perfect score. (I have not actually played all that many, but I also read some of the games press and it seems to be the usual case.) Even the old arcade games fit the pattern: you can't win them, only endure as long as possible, but until then your goal is to impeccably handle every challenge that comes at you. Are there any games in which this is deliberately made impossible? For example, PeerInfinity's suggestion of trying to save drowning people, in a scenario that makes it impossible to save all of them (and which is varied every time you play the game, so you can't simply search out the optimal walk-through). Military operations in a city, fighting door-to-door, with innocent civilians everywhere whose lives matter in game terms.

While I find I have benefitted a great deal from reading posts on OB/LW, I also feel that, given the intellectual abilities of the people involved, the site does not function as an optimally effective way to acquire the art of rationality. I agree that the wiki is a good step in the right direction, but if one of the main goals of LW is to train people to think rationally, I think LW could do more to provide resources for allowing people to bootstrap themselves up from wherever they are to master levels of rationality.

So I ask: What are the optimal software, methods, educational tools, problem sets, etc. the community could provide to help people notice and root out the biases operating in their thinking. The answer may be sources already extant, but I have a proposal.

Despite being a regular reader of OB/LW, I still feel like a novice at the art of rationality. I realize that contributing one's ideas is an effective way to correct one's thinking, but I often feel as though I have all these intellectual sticking points which could be rooted out quite efficiently--if only the proper tools were available. As far as my own learning methods go, assuming a realistic application of curren... (read more)

Worth a top level post.

I think this is a great idea. I'm aware of one simple technology which uses spaced repetition (items you remember or "get correct" taking longer to reappear, for optimal learning), is pre-existing and would be easy to use, which is that of flash card programs. There are a number of free ones out there, two of the best that I found are: Mnemosyne and Anki. I have been using Anki for about half a year now for learning vocabulary (largely for the GRE) and am very happy with it, wish I had discovered such programs earlier. While they're pre-existing and easy to use (and to share and add "cards"), two imperfections stand out. First, I'm not aware of any functionality that lets you actually select an answer. You could look at the question and possible answers and then pick one mentally, but the "answer side" couldn't be customized to the selection you made. Secondly, you of course wouldn't be able to calibrate the questions to your level as the program won't know what you answered. You're able to select to repeat an item very soon, or after short, medium or long intervals (relative to how many times you've answered correctly, by your own scoring), but it's not quite the same. I might be wrong and some existing flash card program might allow for the selection of answers. Or perhaps more promising Anki is open-source, so perhaps with only a bit of work we could build a quiz-version.
0gwern
I don't understand. How do pseudo-multiple choice cards do any worse than a 'genuine' multiple-choice? And what do you mean by calibration? The calibration is done by ease of remembering, same as any card. Nothing stops you from saying (for Mnemosyne), 'if I get within 5% of the correct value, I'll set this at 5; 10%, 4, 20% 3, etc.'
0FrankAdamek
It might well work to one's satisfaction. What I meant by calibration is that it wouldn't be able to give you a different new question based on what you answered; whether you get this question right or wrong, the series of questions awaiting you afterwards is exactly the same (unlike the GRE for example). And if the answer were numeric you could use an algorithm for when to repeat the card, yes. I had off hand imagined questions with discrete answers that had little distance relation.
1gwern
OK... from the sound of it, it isn't really a good application for SRS systems. (They're focused on data, not skills - and thinking through biased problems would seem to be a skill, and something where you don't want to memorize the answer!) However, probably one could still do something. Mnemosyne 2.0 is slated to have extensible card types; I've proposed a card type which will be an arbitrary piece of Python code (since it's running in an interpreter anyway) outputting a question and an answer. My example was generating random questions to learn multiplication (in pseudocode, the card would look like 'x = getRandom(); y = getRandom(); question = print x "" y; answer = print x\y;'), but I think you could also write code that generated biased questions. For example, one could test basic probability by generating 3 random choices: 'Susan is a lawyer' 'Susan is a lawyer but not a sledge-racer' 'Susan is a lawyer from Indiana', and seeing whether the user falls prey to the conjunction fallacy. (As a single card, it would get pushed out to the future by the SRS algorithm pretty quickly; but to get around this you could just create 5 or 10 such cards.)

This writer of this essay (seen on Reddit) is a true practical rationalist and role model for all of us.

It's not just because she made a good decision and didn't get emotionally worked up. She was able to look behind the human level and all its status and blame games, see her husband as a victim of impersonal mental forces (don't know if she knows evo psych, but she certainly has an intuitive grasp of some of the consequences) , and use her understanding to get what she wants. And she does it not in a manipulative or evil kind of way, but out of love and a desire to hold her family together.

If I were that husband, I'd have tried to save my pride even if it meant abandoning the family, because once your pride is taken from you, it's only a matter of time before all the other good things in your life get taken as well.
0arundelo
The author believes that her husband lost pride not for a good reason, but because "[m]aybe that’s what happens when our egos take a hit in midlife and we realize we’re not as young and golden anymore." Do you disagree with her here? If not, how would getting a divorce have been a better solution than realizing that his wife was not the problem?
1cousin_it
IMO the author is correct in her assessment. (Also for the record, I consider her actions admirable.) I'm not saying that getting a divorce is necessarily preferable to staying in such a situation; only that I'd have done it if I saw absolutely no other way to regain pride. There are likely ways to regain pride that don't involve divorce, like the author's first suggestion of "go trekking in Nepal", and of course I'd consider those carefully first.

Your team walks in and finds an area of the pool with a bunch of people drowning (for a team of 4 rescuers, usually it's about 12 victims.) The scoresheets are set up so that you get more points for rescuing the victims who are more likely to survive–i.e. non-swimmers and injured swimmers have a much higher point multiplier than unconscious, submerged victims. PA involves a lot of strategy–it's not always the teams of fast swimmers that win, although that helps. There is an optimal strategy, which has to be worked out in advance because it's a two-minute event.

I've been thinking about educational games as well. The main problem, it seems to me, is that trying to make learning fun for someone who isn't already interested and motivated is a waste of time because you're just trying to hide the teaching under a sugarcoating of computer game, and that never works. On the other hand trying to make learning fun for someone who is already interested and motivated is pointless, because they already want to learn and the game just adds needless hassle like completing levels in order to reach the next piece of knowledge, or whatever game mechanic you're using. It's a pity, because I think of the way games like Portal build up complex puzzles from simpler ones and use the level itself to ask the player leading questions, like a kind of visual/spatial socratic method, and I think there must be a way to use that to teach, espiecally mathematics where visual/spatial metaphors could easily translate into mathematical metaphors... but I just can't come up with a concrete version of the idea that wouldn't be boring or stupid. Lately I've been thinking that the fastest way to get to grips with a new subject is probably just to memorise big chunks of information without trying to understand it, using techniques like a memory palace and spaced learning programs like Mnemosyne and Anki, then think about what you've learned later, and insight might strike you. This would be espiecally effective if you combined it with a social precommitment to teach your knowledge to someone else, or to take part in a competitive quiz.
2[anonymous]
If this is true and you aren't too much of an outlier, it would go a decent way to explain the failure of a good chunk of educational theory in the past few centuries.
3Anubhav
The basic idea works for me, but I think Tom's simplifying it. It's not about "add to Anki with 0% understanding" vs "gain 100% understanding when first learning"; instead, it's more like "add to Anki with 80% understanding" vs "gain 90% understanding, having had to spend several hours for the extra 10%." Far too many people tend to get hung up over that one thing in a chapter that they can't understand. More often than not, it's something they could understand perfectly if they just said "meh" and read a few pages ahead, but no; they just stay stuck on that one spot, thinking "wtf is this??!!" Also, far too many people read books word-by-word when they could get essentially the same amount of information by skimming over the pages. Anki helps here, as it forces you to extract the relevant pieces of information from the text, (or at least stuff that looks important) instead of letting you comfortably wade through a wall of text and believe you've understood it. (It seems, on first glance, that these two paragraphs contradict each other, but they actually don't. The third one is talking about stuff that looks easy but actually isn't, the second one's talking about stuff that looks difficult, but wouldn't if you'd just read ahead.) Also, you generally don't have to wait until later for insight into whatever you've failed to understand... More often than not, insight strikes even as you're adding the cards.

I'm not sure the suggestion of a game in which one cannot 'get the top score' makes sense. It seems contradictory - 'is there an optimal path through the game which is not the optimal path through the game?' Can you have games where the 'path' to a top score, the optimal play, varies from game to game? Sure. Not every game carries it to quite the extent of Nethack, but most do it to some extent. Non-random games like go or chess are generally the exception, and they can be trivially randomized. But each specific game can be seen as ultimately deterministic: given the output of the random number generator this time, the ideal path is such-and-such. You, the player, may not know it, but that's your fault. Can you have games which deceive the player about what the best possible score is? Sure. The original Donkey Kong promises that you can play indefinitely; but go too high and the game will always crash. The upper bound is not where one thought it was. Or there are political games in which one tries to prevent 9/11 (IIRC); of course, the game must sooner or later defeat you, like those old arcade games. What would it mean for a game to have scores players couldn't reach? If in Mario, there is code to paint a picture of a 1-UP on a corner of the screen surrounded by unbreakable blocks, then in what sense is the player missing out on 1k points (or whatever). If a cut scene depicts a hostage dying, then how 'could' I have saved it? What if I can choose between a cut scene depicting hostage A dying, and hostage B? What if it's in-game, and there's a timer or rescuing A triggers the death of B? Or what if there is a trove of 1 million points coded in, but the only access is to type in a true contradiction? Would the world record holder for Mario really be missing 1 million points off his score just because he can't come up with one? (Yes, there is a number equal to his score+1 million; but there's an infinite number of integers. What makes score+1 million special? All

It can make sense if the game does not have a one-dimensional score. World Of Warcraft, The Sims, Second Life, D&D... Life itself, for that matter.
1gwern
If you choose one sub-game, then there's optimal play for that; if you switch between them, then there's still optimal play, it's just you need to weight it if there is no canonical ultimate score (just like with utilities). If there aren't any scores or sense of progress at all, I question whether it's a game at all, or whether it merely bears a Wittgensteinian family resemblance. If you and I push around piled pieces on a Go board just for the pleasure of watching the piles build and collapse and form swirling patterns, we're doing something entertaining (maybe) but who would call it a game? To call life itself a game is to either commit a tired weak metaphor, or to drain the word game of all meaning.

I think Flow is one of the most important ideas to have come out of psychology. My hypothesis for why it's not more widely known is that the creator's name is so difficult to spell and pronounce. My belief is that the learning part of your brain sends a signal to the decision-making part, when the former is experiencing a type of stimulus that is highly learnable. That signal is treated by the decision making part in the same way as a more typically pleasant signal (food, sex, etc) would be. Flow is thus an evolutionary adaptation that makes us seek experiences that help us learn more rapidly (the underlying assumption being that not all stimuli are equally learnable). I think Flow is pretty good as a theory of fun, or as a theory of fun-from-learning. Flow is the best way to learn. The problem is that not all ideas can be learned in a way that meets the Flow criteria (rapid feedback, ability to experiment, clear goals, challenge keyed to ability level). So the interesting questions in my view are how to rephrase learning problems in such a way that one can enter Flow states when approaching those problems.

A few years ago I had developed a theory of game playing and low pressure social group interaction which starts at a similar place as Koster's. I was able to take that starting point about play and patterns and produce empirically testable hypotheses with formal mathematical models of what is happening during play. And then I stopped working on it because I couldn't seem to get across the concept that learning and fun might be related well enough. Now that I've had a chance to read his book, I might have to reconsider.

The Unpleasant Truth Party Game

I wanted to make this idea a new post, but apparently I need karma for that. So I'll just put it here:

The aim is to come up with sentences that are informative, true and maximally offensive. Each of the participants comes up with a sentence. The other participants rate the sentence for two values, how offensive it is on a scale from 0 (perfectly inoffensive) to 1 (the most unspeakable thing imaginable), and how informative it is from 0 (complete gibberish or an utterly obvious untruth) to 1 (immensely precise and true beyond ...

Mathematics Its the foundation for everything else I want to learn. I don't know why I didn't major in it- other than concerns for a paycheck.
1anonym
The nice thing about mathematics is that you can easily do it outside of school and independently, and when you do it as a mature adult, you do it because you love it and for no other reason. You are free to use better texts than you could as a student, so if you want to brush up on calculus, you can use Spivak or Courant rather than being forced to use low-quality texts that are optimized for the convenience of the professor rather than the insight of the student. There are also so many learning resources available now that weren't available when I was a student -- things like wikipedia, planet math, and physicsforums.com, not to mention software like Octave and Sage.
1gwern
I'd like to add that one of the nice things about mathematics as a choice is that you can avoid credentialing issues. I'm sure we've all read Hanson on how most of the value of a college degree is in that the college is certifying your abilities, and stamping you. If you chose world-class ability in economics/financial trading, say, and you are a poor student, then what are you going to do with it? You can't make a killing on the market to prove your abilities; you can't go work as an intern for a firm to prove your knowledge, etc. Similarly with genetics. If I suddenly gained world-class genetic knowledge, I cannot walk up to Cold Spring Harbor and ask them to let me use some multi-million dollar equipment for a year because I have this awesome bit of research I'd like to do. I simply don't have any proof that I'm not a random bozo who has memorized a bunch of textbooks and papers. I'd have to get lucky and convince a professor or somebody to take me on as an assistant and slowly build up my credentials until I can do the bit of research that will irrefutably establish me as a leading luminary. Or how about physics? If I specialize in experimental or practical physics, I have the same chicken-and-egg problem; if I specialize in theoretical, then I run the risk of simply being ignored, or written off as a crank (and the better my contribution, the more likely I am to be seen as a crank!). But with mathematics, I can just crank out a bunch of theorems and send in a paper. If people are still unconvinced, being a mathematical genius, I can just formalize it and send in a Coq/Isabelle/Twelf file consisting solely of the proof.
0anonym
While mathematics certainly appears to me to be more of a meritocracy than the sciences, it's still the case that the notion of proof has changed over time -- and continues to change (witness Coq and friends) --, as have standards of rigor and what counts as mathematics. There are social and other non-mathematical reasons that influence how and why some ideas are accepted while others are rejected only to be accepted later, and vice versa. It's an interesting question whether this will always be the case or if it will converge on something approaching unanimously accepted truth and aesthetic criteria. Personally, I think mathematics is intrinsically an artistic endeavor and that the aesthetic aspect of it will never disappear. And where there is aesthetics, there is also politics and other sausage-making activities...
0Richard_Kennaway
The gold standard of what is a proof and what is not was achieved with the first-order predicate calculus a century ago and has not changed since. Leibniz' dream has been realised in this area. However, no-one troubles to explicitly use the perfect language of mathematical proof and nothing else, except when the act of doing so is the point. It is enough to be able to speak it, and thereafter to use its idioms to the extent necessary to clearly communicate one's ideas. On the other hand, what proofs or theorems mathematicians find important or interesting will always be changing.
0gwern
I don't really think the question is whether mathematics is more meritocratic - it's an economic question of credentialing. You need credentialing when you cannot cheaply verify performance. If I had a personal LHC and wrote a paper based on its results, I don't think anyone would care too much about whether I have 2 PhDs or just a GED - the particle physicists would accept it. But of course, nobody has a personal LHC. With mathematics, with formal machine-checkable proofs, the cost of verification is about as low as possible. How long does it take to load a Coq proof and check it? A second or two? Then all someone needs to do is take a look at my few premises; either the premises are dodgy (which should be obvious), or they're common & acceptable (in which case they know I'm a math genius), or I'm exploiting a Coq flaw (in which case I'm also a math genius). Once they rule out #1, I'm golden and can begin turning the genie's gift to good account.
0anonym
By meritocracy, I meant what you explain by credentialing: the idea that the work alone is absolutely sufficient to establish itself as genius or crackpottery or obvious or uninteresting or whatever, that who you are, who you know, where you went to school and who your advisors were, which conferences you've presented at, the time and culture in which you find yourself, whether you're working in a trendy sub-discipline, etc., that all that is irrelevant. How much of mathematics is machine-checkable now? My (possibly mistaken) understanding was that even the optimists didn't expect most of existing mathematics for decades at least. And how will we formalize the new branches of mathematics that have yet to be invented? They won't spring forth fully formed as Coq proofs. Instead, they'll be established person-to-person at the whiteboard, explained in coffee shops and over chinese food in between workshop sessions. And much, much later, somebody will formalize the radically revised descendant of the original proof, when the cutting edge has moved on. I'll know you're right and I'm wrong if I ever begin to hear regular announcements of important new theorems being given in machine-checkable format by unaffiliated non-professionals and their being lauded quickly by the professionals. And that is the easier task, since it is the creation of new branches and the abstraction and merging of seemingly unrelated or only distantly related branches that is the heart of mathematics, and that seems even less likely to be able to be submitted to a theorem prover in the foreseeable future.

I'm not sure how one would measure that. The Metamath project claims over 8k proofs, starting with ZFC set theory. I would guess that has formalized quite a bit. I think that only follows if genius outsiders really do need to break into mathematics. Most math is at the point where outsiders can't do Fields-level work without becoming in the process insiders. Consider Perelman with Poincare's conjecture - he sounds like an outsider, but if you look at his biography he was an insider (even just through his mother!).

This is what I thought everyone was going to say. I don't see why you'd be concerned about the paycheck though, a strong mathematics background could land you a job as a banker or trader or something. But looking at your upvotes it seems like plenty of people agree with you. My next question would be what you'd like to have a basic introduction to. Plenty of LW posts tend to assume a grounding in subjects like maths, economics or philosophy - which is fine, this is a community for informed people - but it probably shrinks LW's audience somewhat, and certainly shrinks the pool of people who are able to understand all the posts. We probably miss this because nobody's going to jump into the middle of a thread and say, "I lack the education to understand this." espiecally not a casual reader.

My upvotes are probably due to the fact that I said mathematics, rather than any agreement concerning my potential lack of paycheck. I know that a mathematics background could supply me a paycheck at this point in my life, but I was urged against it by some other people when I was choosing my major. Basic introduction to? Is this in addition to the expertise I got from the genie, or if the genie was only offering me a basic introduction? Do I only get to choose one? Gee that's hard. I'm pretty much working on having a basic introduction to everything already. So, given my existing basic introductions... I think I'd like to get a basic introduction to quantum physics... but that's kind of cheating because I'd have to know a lot of physics and mathematics in the basic intro. I choose that one because I want to know it for purely vain reasons, and it would be nice to save the time of learning it for more "useful" studies. This blog definitely is going to appeal to a minority of people. I personally do not have the proper education to follow the bayesian/frequentist debate, though I want to hear about it. I think that the healthy practice of linking to information is fantastic, as well as the lesswrong wiki. That way if you know what the person is talking about, you don't have to follow the link, but if you need to learn, it's right there at your fingertips. Edit: Oh right, and I can't contribute to quantum physics discussions very well either.

Hello, I went through the archive of your magical girl comic. I'm gonna keep my eye on it. The way the premise is presented is nonsensical, but that's a-ok in the genre, and I suspect you just wanted to through the setup quickly. Girls' publicity is a nice twist to the trope, and I hope you'll explore it thoroughly. I really like the tiny dragons - my favorite strip involves them. Oh, and the fact that the girls are not lawful stupid (a too common disorder among magical girls) is a big, big plus. On the flipside, I think you should work on backgrounds and perspective more. Especially Datekaln - painting its sky solid green doesn't do it justice. At least make a reusable texture like you did with Earth's sky presumably.

Thanks for the feedback. Everybody loves the pagets and everybody loves that page - I should change the title to "Pagets Are Cute (and some silly humans sometimes do things)."

For personal interest, neuroscience (and the genie would wave his wand, and I would be V. Ramachandran). For benefit to society, probably genetics (or do colleges offer degrees in AI?) I'd also like to see if I could use the genie to answer one of the great questions of the ages. I guess it all depends on how the "expert" thing is implemented. For example, if the genie created a great expert in quantum mechanics, would the expert simply know and understand facts about quantum mechanics, or would they also be such an expert as to have the correct opinion on the Copenhagen vs. many worlds question? After all, Tom did say "an expert equivalent to the greatest mind today", and there are minds that are pretty sure they know the answer to that question, so the mind that has the correct opinion on it must be greater than an equivalent mind that doesn't. That means if I wake up and find myself believing Many Worlds, I have very strong evidence that Many Worlds is correct. If I thought that plan would work, I'd probably choose Philosophy. I might get kicked in the 'nads, but for the chance to have genie-approved answers all the great philosophical questions at once, it'd be worth it.

I'm more likely to become massively rich by being a fantastic singer than I am to become massively rich by being a fantastic philosopher, or even a fantastic economist. My education-related values change some if I don't have to invest time or effort in acquiring the expertise. That said, I don't think I'll pick singing. I think I'll pick creative writing.

It's always fun to see what empirical facts might change one's assessment. Philosophers, ever since Thales at least, haven't been known for wealth but - Are you sure becoming one of the greatest economists in the world wouldn't be likely to make you massively rich? I'm sure we both agree that the average economist makes more than your average singer (and median too); but have you considered that superstar economists can still make more than superstar singers? Michael Jackson is one of the wealthiest singers of all time (wealthiest?), yet he died with maybe 500 million USD in assets; there were hedge fund folks who made several times that in 2008 alone. And he doesn't hold a candle to Warren Buffett. Or consider Lawrence Summers. Despite a career largely spent in government or academia, his world-class status means that he can do things like pick up a >5million USD a year salary working less than a day a week. We may argue that these kind of financial bonuses are obscene and unfair, but economists and other financial types reap them nevertheless...

I'm sure that extraordinary expertise at economics would enable people with the right mindset to make large amounts of money, but the obvious avenues (e.g. spending all day trading stocks) would not interest me, and I'd be unlikely to value the money enough to put up with them in the quantity necessary to become massively rich. If I magically acquired extraordinary expertise at economics, I'd probably mess around with it until I had enough money to hand the reins to a less-skilled accountant to handle and invest for me and keep me in housing and groceries for the rest of my life. I'd be more comfortably upper-middle-class than rich. It's possible that my extraordinary expertise at economics would also inform me of fun ways to make money with it, but none spring immediately to my unskilled-at-economics mind.

Its quite a leap to go from economist to hedge fund manager. Their skill sets are not at all the same. The best way to make bank if you are a brilliant economist is: 1) make a fundamental contribution to economics, especially related to finance. 2) win nobel prize or at least have your contribution adopted by industry. 3) get paid millions to "consult" or "advise" hedge fund managers who will use your name to attract investors and probably never ask you to do actual work.

So you pick the area with the highest expected monetary payoff? I'm not sure that skills in singing or creative writing serve that end, since the competition is so intense and the selection process for successful singers and writers seems somewhat arbitrary and random. I see what you mean about the amount of effort required changing which area you would pick, and that was part of what I was getting at. I wonder how many of us choose to study a particular subject because it's easier than the alternatives, then rationalise it later as what we really wanted. If effort wasn't a factor and you could have chosen to study anything, what would it have been? If we on Less Wrong find ways to make learning easier, what will you do?
1Alicorn
Creative writing might not serve that end, but it's hardly the longest of long shots, and moreover, writing creatively is something I enjoy, unlike doing math or working on hard science or whatever. So even if I don't wind up writing bestselling books and making a billion dollars, I can still have fun writing excellent books. It's a tradeoff between expected monetary payoff, and the enjoyability of the task to turn the skill into the payoff. I'm studying philosophy because most of the time, studying philosophy is fun. It's not consistently easy, and it's not going to make me a lot of money now or later, but it entertains me. If effort wasn't a factor I could study, oh, medicine, and be a brilliant physician, or law and be a brilliant lawyer, but I don't expect that (even effort aside) I would enjoy the study or practice of those fields.
0Tom_Talbot
So you wouldn't pick instant expertise in philosophy because that would take the fun out of it. Do you think that if studying philosophy was easier, it would be less fun? I'm not convinced because no matter how much of an expert you are, there's still more to learn. The genie is offering you the chance to be at the cutting edge of your field.
2Alicorn
No. I'm saying that fun is my motivation for studying philosophy, because when I decide how to invest years of my life, I want to choose fun investments. Your genie opens up the options of choosing to (productively) invest directly in the practice, rather than the study, of various fields. There are fields that I think I would enjoy being an expert in that I would not enjoy the process of studying to become an expert in, especially when you consider that intrinsic talent/motivation/etc. might block me from acquiring expertise in some fields that the genie could make me brilliant at. Some of those fields might also net me money. Bypassing a potentially-unfun studying step makes several of them more appealing than philosophy.
1Tom_Talbot
OK, I see where you're coming from. Learning to play the violin is frustrating, but it's probably fun once you can do it. So if we could find a way to make learning easier, hypothetically speaking, you would use that opportunity to be a better generalist rather than further specialising in your chosen area? That's interesting because specialists are usually better paid. I wonder if that's a common point of view. LWers are generalists, in general. Most of us know some psychology, some economics, some philosophy, some programming and so on. But I wonder what Less Wrong would be like if we all specialised, while remaining united by the pursuit of rationality. I think Robin Hanson said something similar in that post where he compared us to survivalists, trying to learn everything and failing to reap the benefits of specialisation and cooperation. Anyway sorry for rambling like this. I tend to use these open threads as an opportunity to think out loud, and nobody's told me to shut up yet so I just keep going.
1Alicorn
If learning, in general, became easier for me, I would learn more, in general. I don't think I'd use it to do more philosophy; I think I'd use it to do the same amount of philosophy in less time. If learning became a whole lot easier, I'd probably study foreign languages in my spare time. The ability to communicate in more languages would open up more learning potential than most other tasks.

A very common belief here is that most human behaviour is based on Paleolithic genes, and only trivial variations are cultural (memetic), coming from fresh genes, or from some other sources.

But how strong is the evidence of Paleogenes vs memes vs fresh genes (vs everything else)?

Fresh genes are easy to test - different populations would have different levels of such genes, so we could test for that.

An obvious problem with Paleogenes is that there aren't really that many genes to work with. Also, do we know of any genetic variations that alter these behavio... (read more)

I think we can fairly easily come up with examples of things that are regarded as attractive in some cultures and not others. For example, tanned skin. Back in the "olden days" in Europe, pale skin was considered the ideal. The much-desired "fair maiden" in old tales is literally one with light-colored skin that is kept out of the sun so it doesn't tan. Today, in the U.S. at least, skin with a slightly bronze tan is often considered the ideal. This may or may not have to do with social class. Prior to industrialization, lower class people would be tanned from working outside on farms, while higher class people (nobility, etc.) could stay inside and keep their skin nice and pale. Once poor people switched from working on farms to working in indoor factories, they, too, had pale skin, while the wealthier could afford to waste time sitting in the sun getting a tan. "Find signals of high status attractive" might be a genetically influenced trait (I'd be surprised if it weren't) but genes don't seem to determine exactly how people signal high status. Plenty of behavior has genetic influences, but people learn an awful lot from their environment, too. When a dog is trained to roll over on command, is that a genetic behavior? If it is, then so is everything and it becomes a meaningless category.
3orthonormal
Brain-coding phenomena like sexual preferences seem to be built from large collections of genes that are interconnencted with other systems, such that there aren't many possible mutations that would undo the feature without wreaking havoc elsewhere in the phenotype as well. In fact, the universality of such preferences across neurologically intact humans is evidence that they come from Paleogenes rather than memes or fresh genes, either of which can more easily be altered without deleterious effects elsewhere.
1taw
I'm not saying Paleogenes are not a possible explanation, but I haven't seen much in terms of such evidence like: * I don't think it's so common for people to go around the world, and actually verify that people in statistically significant number of virtually isolated tribes do have preferences for larger breasts etc. So universality is more postulated than actually empirically found. Even if you find extremely common behaviour, it can still be memetic, as a lot of memes are copied from parents to children. How many behaviours are empirically known to be universal? * Mutations to such genes would be non-lethal, and some would only mildly reduce inclusive fitness. We have plenty of genetic diseases in the population affecting more important genes. So how come we haven't discovered mutations in the wild that alter genes controlling this supposedly genetic behaviour. * We know very few genes obviously linked with behaviour, and saying it's coded by emergent interaction of multiple genes is just handwaving away the problem. There's a pretty low ceiling of how much can be straightforwardly coded this way, and I'd expect some serious evidence of some mechanism of complex genetically coded behaviour.
0Nanani
http://the10000yearexplosion.com/ The 10000 year Explosion shows very good evidence that this isn't quite true; many significant genetic adaptations are indeed far more recent and have been developping faster since the end of the Paleolithic. It's also an enjoyable read.

On the other hand, do we have disconfirming evidence? (Would we expect to have noticed?)

All such evidence would be expected to come from different times or from isolated communities, today vast majority of the world population lives in one connected memetic soup. Unfortunately I don't know enough about anthropology to give particularly convincing evidence. Wikipedia search suggests some cultures don't care much about breasts at all, what you can consider weak evidence against Paleogenetic explanation.
0gwern
Weak, yeah. After all, Westerners consider the face to be a great part of a person's sex appeal, and it's very important in sex (kissing, oral sex, etc.) - yet they don't cover it up. Do they not care? What's really needed is data showing that breast size or proportions are uncorrelated with reproductive success, or at least with ratings of attractiveness.

Sure: "All conventional theories of cultural evolution, of the origin of humans, and what makes us so different from other species. All other theories explaining the big brain, and language and tool use and all these things that make us unique, are based upon genes. Language must have been useful for the genes. Tool use must have enhanced our survival, mating and so on. It always comes back, as Richard Dawkins complained all that long time ago, it always comes back to genes. The point of memetics is to say, "Oh no it doesn't." There are two replicators now on this planet. From the moment that our ancestors, perhaps two and a half million years ago or so, began imitating, there was a new copying process. Copying with variation and selection. A new replicator was let loose" [...] - Sue Blackmore.

There's very convincing evidence that ability to use language is genetic, up to specific kinds of brain damage and specific kinds of genetic diseases that cause very particular types of language impairment. Language itself is memetically built on top of that. I've never seen such evidence for any other kind of behaviour.
-1timtyler
I am not sure what you mean - or how it is relevant. Plenty of behaviour has a genetic basis. Eating behaviour and sexual behaviour, for instance. If you look at all the reflexes and instincts out there, you will see that many types of behaviour have a genetic basis. Even if everything was learned (the "blank slate" hypothesis) - so what? How would that be relevant to the idea of cultural inheritance being significant?

Ask the person questions you know they will lie about and watch their body language very closely. Compare it with their body language when you know they are telling the truth or relaxed. Then when you see signs of the lying body language in future, probe further and see if you can uncover the lie. My favourite way of doing this isn't even with deception. I use a bit of PUA-style material as follows: "Hey, I've known you a while now, I reckon I can guess a few facts about you. Here's what I want you to do. I want you to come up with four facts about yourself, but one of them has to be a LIE. Tell me them in any order and I'll see if I can spot the lie. It will be fun, and you'll learn something about yourself!" etc. etc. People love this kind of thing (because it's about themselves), and they love thinking that you have special powers or an intimate psychic connection with them. Of course, most people on LW would see it as a challenge to mislead me into choosing the wrong lie, but that's not usually what happens in my experience. It doesn't matter if you don't spot the lie, because if you're paying attention to their body language throughout the whole conversation, you should pick up plenty of their ticks and be able to associate them with particular emotions. You can invert the idea with anchoring too, if you know what you're doing. If you anchor a particular gesture or touch to when they are open and honest with you then you can use it later when you want them to answer truthfully. It's never a case of people having a single fixed truth-telling body language and a single fixed lying body language, but that when they're lying they subconsciously change something in how they appear. It's "spot the odd one out" which makes the lie easy to spot. Then there's stuff like looking into the a top corner when trying to remember something. If you ask someone three difficult memory questions and they look into the top left corner for two of them but then look off to the

I originally wasn't going to reply because I'm not entirely sure if it's a good idea for other people to adopt my strategy, but my name has been uttered, so I'll give it a shot. I have no strategy directly aimed at detecting lies. I notice when someone's statement seems to contradict something I already believe, and I notice when someone's statement seems just plain wacky. I tend not to believe those statements, unless the preexisting belief they contradict is equally unsupported (which means I don't care much about the subject and might as well be agreeable with whoever I'm talking to), or I have an extended friendship with and favorable insight into the ethics and intellect of the speaker (so I think they'd be especially unlikely to lie to me or be mistaken), or I seek additional information and find the statement confirmed by legitimate-looking other sources (which I do when I care about the subject a great deal, regardless of my opinion of the likelihood of lying/mistake). But other than that, I'm a very trusting person. The lies and errors that slip through this admittedly unsophisticated web of detection are usually caught when I permit myself to become loudly curious, which happens whenever I care about a subject. (It matters very little to me if I have false beliefs on subjects that are of no importance to me). Your average liar cannot tolerate extensive, earnest questioning about the details of the situation about which they have lied, even if there are legitimate-looking sources which back them up. When this inquisition turns up a falsehood, I typically operate under the assumption that it was a mistake rather than a deliberate attempt at deception; this seems to make most people less likely to resent me, and is probably true much of the time anyway.

Weird. I couldn't imagine participating in that sort of thing, but then I can't really imagine specifics about what you're talking about. I imagine that if anyone at my day job tried to engage in something other than programming ("rumors and politics" presumably don't involve programming) they'd be asked to stop, and fired if it kept up. And every code commit is logged, so I don't see how anyone could be dishonest about that.

Good question. I hope you get a few more answers, and I particularly hope Alicorn comments on this, since she's also autistic but seems to have a different strategy for dealing with people than I do. Here's my first approximation, which may not be completely accurate: For intentional lies, simply keeping track of what they've said in the past, and the implications of what they've said, works well. Many people don't have the kind of memory to be able to be completely consistent with their lies even without taking the implications into account, and keeping the implications of any kind of significant lie consistent with both reality and itself over time is practically impossible. Not every instance of that is a lie, of course - people also tend to change their minds or find new information and not explicitly state that - but it's a good warning sign. Figuring out that there's a flaw in what someone truly believes is harder, and a more common issue. My strategy is to find the base assumptions that their view rests on, and evaluate those for truth. (This also sometimes works on intentional lies, though with those it's often true that there are no underlying assumptions - which is another clue that something's wrong.) Generally, at least one assumption will be questionable, which is okay - I just have to evaluate that assumption in each situation before I consider taking advice based on it. If one of the underlying assumptions is obviously false, or questionable, I consider the advice suspect. Both of those strategies feel similar to what you described, so you might be able to figure out how to do them. I can do what you described, but not often; it seems to conflict with being verbal.

A number of days ago I was arguing with AngryParsley about how to value future actions; I thought it was obvious one should maximize the total utility over all people the action affected, while he thought it equally self-evident that maximizing average utility was better still. When I went to look, I couldn't see any posts on LW or OB on this topic.

Total utility has obvious problem - it's only meaningful to talk about relative utilities so where do we put zero? (as it's completely arbitrary) * If zero is very low, then total utility maximization = make as many people as possible * If zero is very high, then total utility maximization = it's kill everyone * If zero is average utility, then total utility maximization = doesn't matter what you do None of the three make any sense whatsoever.
2CronoDAS
You've already decided where to put zero when you say this: That means that zero is the utility of not existing. Granted, it's a lot easier to compare two different possible lives than it is to compare a possible life to that life not coming into existence, but by saying "kill anyone whose utility is less than zero" you're defining zero utility as the utility of a dead person. Also, does not make sense to me. Utility is relative, yes, but it's relative to states of the universe, not to other people. If average utility is currently zero, and then, let's say, I recover from an illness than has been causing me distress, then my personal utility has increased, and average utility is no longer zero. Other people don't magically lose utility when I happen to gain some. Total utility doesn't renormalize in the way you seem to think it does.
0orthonormal
Repugnant conclusion certainly is worth discussing, but the other two: I think it would be a very bad idea to have a utility function such that the utility of an empty universe is higher than the utility of a populated non-dystopia; so any utility function for the universe that I might approve should have a pretty hefty negative value for empty universes. I don't think that's too awful of a requirement. This looks like a total non sequitur to me. What do you mean?
1Cyan
He means that if utility is measured in such a way that average utility is always zero, then total utility is always zero too, average utility being total utility divided number of agents.
1orthonormal
Well, that's not a very good utility function then, and taw's three possibilities are nowhere near exhausting the range of possibilities.
0taw
So where do you put zero? By this one completely arbitrary decision you can collapse total utility maximization to one of these cases. It gets far worse when you try to apply it to animals. As for zero being very high, I've actually heard many times this argument about existence of farm animals, which supposedly suffer so much that it would be better if they didn't exist. It can as easily be applied to wild animals, even though it's far less common to do so. With animal zero very low, total utility maximization turns us into paperclip maximizer of insects, or whatever is the simplest utility-positive life.
4CronoDAS
If non-existent beings have exactly zero utility - that any being with less than zero utility ought not to have come into existence - then the choice of where to put zero is clearly not arbitrary.

Yeah, that doesn't surprise me. But the context of our discussion was certainly different! I had suggested to AngryParsley that even if we had next to no understanding of how to modify our minds for the better, uploading would still be useful since we could make 10 copies of ourselves with semi-random changes, and let only the best one propagate; he objected that how did I plan to get rid of the excess 9? By murder was plainly awfully immoral, and my suggestion of forcing them to live out the standard 4 score and 10 only somewhat less so - by not allowing them to be immortal or whatever the selected copy would get, I would be lowering the average. (Going by totals, this of course isn't an issue.)
0torekp
The Mere Addition Paradox suffices to refute the AVG view. From Nick's link: For example, A+ could evolve from A by the choice of some parents to have children whose quality of life is good, though not as good as the average in A. We can even suppose that this makes the parents a little happier, while still lowering the overall average.

Thanks for the link. And you are right, by Jove, these philosophers really like to go on about it -- ie.the whole issue could be summarized as the question whether we should optimize for AVG(good) or for SUM(good) -- and some variations. A question that ultimately cannot be answered. The length of the bibliography makes it almost comical.
0Psy-Kosh
The main problem I have with AVG is that it implies that as population increases, inherent value of each individual decreases. Why should you be suddenly less important simply because someone else was just born? (I don't mean the instrumental components of your value but your inherent value)
-2timtyler
What you "should" do depends on what your goal is. Most biological organisms don't maximise either of your proposed functions - their utility function is down to how many great grandchildren they have - not how many people they help.
2gwern
I don't really see how what most organisms do is relevant; we're discussing what's moral/ethical for human beings. This is quite relevant to deciding whether to say, help out Africa (which with its very high birth rates is equivalent to plumping for total) or work on issues in the rest of the world (average).
-3timtyler
As I understand it, there is widespread disagreement on that issue. Most humans don't seem to have a clear idea of what their goals are, and of those that do, there is considerable disagreement about what those goals are. Scientists can model human goals. The result seems to be that humans act so as to try to maximise their genes - and sometimes the memes they have been infected with. Basically all goal-directed behaviour is the result of some optimisation process - and in biology, that process usually involves differential reproductive success of replicators. Human goal-seeking behaviour thus depends on the details of the memes the humans have been infected with - which mostly explains why humans vocalise a diverse range of goals. Humans often spread the patterns they copy while working from hypotheses about how the world works that are long out of date. Also organisms often break and malfunction as a result of developmental problems and/or environmental stresses - so these theories are not always as good as we would like.

One thing that I've been wondering about (but not enough to turn it into a proper thread) is how to talk about consequentialist morality. Deontologists can use thought experiments, because they're all about rules, and getting rid of unnecessary real world context makes it easier for them.

Consequentialists cannot use tricks like that - when asked if it's ok to torture someone in a "ticking bomb" scenario, answering that real world doesn't work like that due to possibility of mistakes, how likely is torture to work, slippery slope, potential abuse of torturing power once granted etc. is a perfectly valid reply.

So if we cannot really use thought experiments, how are we supposed to talk about it?

Reply
2Cyan
What prevents a consequentialist from accepting various hypothetical conditions arguendo and working out their consequences? I'd consider it a possibly bad idea to actually do so, what with the known cognitive biases that might skew future decision making; but accepting arguendo that a particular consequentialist has overcome these biases, I can't see a reason for her to refuse to consider least-convenient-world scenarios.
1taw
Moral rules are about actions, but in consequentalism are judged strictly according to their consequences. Real world is what connects actions to consequences, otherwise we couldn't talk about morality at all. If you assume some vast simplification of the real world, or assume least-convenient-world, or something like that, the connection between actions and consequences completely changes, and so optimal moral rules in such case have no reason to be applicable to the real world. Also if the real world changes significantly - let's say we develop a fully reliable lie detector and start using it all the time (something I consider extremely unlikely in the real world). In such case the same actions would have different consequences, so consequentialism would say our moral rules controlling our actions should change. For example if we had lie detectors like that it would be a good idea to get every person routinely tested annually if they committed a serious crime like murder or bribery - something that would be a very bad idea in our real world.
2Cyan
Ah, I see. You meant that consequentialists can't use simplified or extreme hypothetical scenarios to talk about consequentialist morality as applied to real decisions, not that they can't do it at all. That was implicit in your ticking-time-bomb example but not explicit in your opening, and I missed it. (I agree.)
0freyley
Shouldn't thought experiments for consequentialism then emphasize the difficult task of correctly determining the consequences from minimal data? It seems like your thought experiments would want to be stripped down versions of real events to try to guess, from a random set of features (to mimic the randomness of which aspects of the situation you would notice at the time), what the consequences of a particular decision were. So you'd hold the decision and guess the consequences from the initial featureset.
0marks
There's another issue too, which is that it is extraordinarily complicated to assess what the ultimate outcome of particular behavior is. I think this opens up a statistical question of what kinds of behaviors are "significant", in the sense that if you are choosing between A and B, is it possible to distinguish A and B or are they approximately the same. In some cases they won't be, but I think that in very many they would.
1billswift
That's why I believe a person is responsible for the foreseeable consequences of their actions. If the chain of effects is so convoluted that a particular result cannot be foreseen than it should not be used to access the reasonableness of a person's actions. Which is why I think general principles should guide large areas of our actions, such as refraining from coercion and fraud, even for a consequentialist.
0conchis
I am sympathetic to this, but would at least want to modify it to responsibility for reasonably foreseeable consequences. What is foreseeable is endogenous - it is a function of our actions and our choices to seek information. We generally don't want to absolve people of responsibility for actions which were not foreseeable only because they were reckless as to the consequences of their actions, and didn't bother to gather sufficient information to make a proper decision.
0djcb
I doubt there actually are any strict consequentialists (or strict deontologists for that matter). E.g., would anyone be in favour of not punishing failed murder attempts? To me, consequentialism/deontology always seem like post-hoc explanations of our not all too rational moral intuitions -- useful to describe the 'moral rules playing field', but not saying very much about who people really decide how to act.
0pengvado
What does punishment have to do with consequentialism -- Are you hypothesizing that not punishing failed murder attempts would reduce the number of successful murders, but that even people claiming to be consequentialists and claiming to value that consequence wouldn't consider that solution? I would certainly be in favor of any reduction in punishment if it can be shown that the reduced punishment is more of a deterrent than the original. Or are you saying that a murder attempt shouldn't count as murder if no one actually died, and comparing that to your intuition of judging the intentions rather than the consequences? But intentions do matter when evaluating what effect a given punishment policy has on the decisions of potential murderers.
0djcb
Well, strict consequentialists determine the goodness or badness of an action only by the consequences, not by the intentions of the actor. And that seems to fly in the face of our moral intuitions (as in the attempted murder example), which is why I hypothesized that there are not many strict consequentialist. As you suggest, a possible way out would be to say that we punish even attempted murder, because it might discourage others to attempt (and possibly succeed) doing the same. And that is what I would call a 'post-hoc explanation'.
0[anonymous]
The consequentialist can't Know the consequences of the actions, but he can list the likely possibilities and assign probabilities and error bars to the consequences. If there's no difference in probability between the more and less desirable consequence, or if the difference is well within the error bars, then there's no way to determine whether the action is right or wrong using consequentialist morality. For instance, if there's a 50/50 chance torture will give you the answer, there's no way to make the right choice. If it's 60/40 with +-30 error bars, you still can't make a right choice (though the maximum error bar overlap is a matter of personal moral configuration). But if it's 70/30 with +-5 error bars, a consequentialist can make a choice. This is, of course, complicated by the fact that we're loaded with cognitive biases that will lead most people to make probability mistakes in a "ticking bomb" situation, and guessing error bars is equally a difficult skill to master. That, and most real situations aren't simple dilemmas, but intractable quagmires of cascading consequences.
1marks
I think you're making an important point about the uncertainty of what impact our actions will have. However, I think the right way to about handling this issue is to put a bound on what impacts of our actions are likely to be significant. As an extreme example, I think I have seen much evidence that clapping my hands once right now will have essentially no impact on the people living in Tripoli. Very likely clapping my hands will only affect myself (as no one is presently around) and probably in no huge way. I have not done a formal statistical model to assess the significance, but I can probably state the significance is relatively low. If we can analyze what events are significant or not causally for others then we would certainly make the moral inference problem much simpler.
0[anonymous]
Good point, cutting off very low-impact consequences is a necessary addition to keep you from spending forever worrying. I think you could apply the significance cutoff when making the initial list of consequences, then assign probabilities and uncertainty to those consequences that made the cut. Your example also reminded me of butterflies and hurricanes. It's sensible to have a cutoff for extremely low probabilities too (there is some chance that clapping your hands will cause a hurricane, but it's not worth considering). The probability bound would solve the problem of cascading consequences too. For a choice, you can make some probability distribution that it will, say, benefit your child. You can then take each scenario you've thought of and ranked as significant and possible, and consider the impact on your grandchildren. But now you're multiplying probabilities, and in most cases will quickly end up with insignificantly small probabilities for each secondary consequence, not worth worrying about. (Something seems off with this idea I just added to yours - I feel like there should be some relation between the difference in probability and the difference in value, but I'm not sure if that's actually so, or what it should be.)

Even apart from apparent mind-killing properties of this proposal, I don't think it's reasonable. First, it's unnecessary: if you expect the probability of a positive intelligence explosion to go up even a little bit as a result of your donation, the crazy positive utility of the outcome compensates for the donation. If you don't think the donation affects the outcome, don't donate. Second, implementation of some compensation mechanism is an ad-hoc rule that isn't necessarily possible to attach to the AI's goals in a harmless way, so you can't promise that it will be done. Also, if something of the kind is really a good idea, FAI should be able to implement it regardless of what you promise now, without tweaking of its goals.

Some small number of new regulars will use the ratings to decide what to read, but most of them won't do that until after they read a bunch that were linked recently.

Well, just to give an example, if someone comes in and sees Engines of Cognition, regarded by many here as one of the best posts, they may be misled by its rating of 3, compared to EY's typical 30+ rating for newer posts which, while good, are not the classic must-read that Engines of Cognition is.

I don't know if it is appropriate to even post this thing, but I didn't find a single thread which talks about the kind of music people in this forum listen to. Has it ever happened that you have used rationality to decide the kind of music you should be listening to? Like all the other things, even listening to music needs "training" (the ears in this case). Music is art-form, so can it be quantified? One might get the same satisfaction listen to MJ or Pat Metheny. But if it happens that you have to choose only two records to listen to for the rest of your life, can rationality help there?

In a word, no. Rationality can't tell you what to like, it can only tell you how to get it once you know it. If you had clearly defined criteria for what good music is, you could use reason along with these criteria to select music efficiently. Reason can't tell you what the criteria are.
