But I finally snapped after reading: Mandatory Secret Identities
Okay, the title was for shock value. Rationality is pretty great. Just not quite as great as everyone here seems to think it is.
For this post, I will be using "extreme rationality" or "x-rationality" in the sense of "techniques and theories from Overcoming Bias, Less Wrong, or similar deliberate formal rationality study programs, above and beyond the standard level of rationality possessed by an intelligent science-literate person without formal rationalist training." It seems pretty uncontroversial that there are massive benefits from going from a completely irrational moron to the average intelligent person's level. I'm coining this new term so there's no temptation to confuse x-rationality with normal, lower-level rationality.
And for this post, I use "benefits" or "practical benefits" to mean anything not relating to philosophy, truth, winning debates, or a sense of personal satisfaction from understanding things better. Money, status, popularity, and scientific discovery all count.
So, what are these "benefits" of "x-rationality"?
A while back, Vladimir Nesov asked exactly that, and made a thread for people to list all of the positive effects x-rationality had on their lives. Only a handful responded, and most responses weren't very practical. Anna Salamon, one of the few people to give a really impressive list of benefits, wrote:
I'm surprised there are so few apparent gains listed. Are most people who benefited just being silent? We should expect a certain number of headache-cures, etc., just by placebo effects or coincidences of timing.
There have since been a few more people claiming practical benefits from x-rationality, but we should generally expect more people to claim benefits than to actually experience them. Anna mentions the placebo effect, and to that I would add cognitive dissonance - people spent all this time learning x-rationality, so it MUST have helped them! - and the same sort of confirmation bias that makes Christians swear that their prayers really work.
I find my personal experience in accord with the evidence from Vladimir's thread. I've gotten countless clarity-of-mind benefits from Overcoming Bias' x-rationality, but practical benefits? Aside from some peripheral disciplines1, I can't think of any.
Looking over history, I do not find any tendency for successful people to have made a formal study of x-rationality. This isn't entirely fair, because the discipline has expanded vastly over the past fifty years, but the basics - syllogisms, fallacies, and the like - have been around much longer. The few groups who made a concerted effort to study x-rationality didn't shoot off an unusual number of geniuses - the Korzybskians are a good example. In fact as far as I know the only follower of Korzybski to turn his ideas into a vast personal empire of fame and fortune was (ironically!) L. Ron Hubbard, who took the basic concept of techniques to purge confusions from the mind, replaced the substance with a bunch of attractive flim-flam, and founded Scientology. And like Hubbard's superstar followers, many of this century's most successful people have been notably irrational.
There seems to me to be approximately zero empirical evidence that x-rationality has a large effect on your practical success, and some anecdotal empirical evidence against it. The evidence in favor of the proposition right now seems to be its sheer obviousness. Rationality is the study of knowing the truth and making good decisions. How the heck could knowing more than everyone else and making better decisions than them not make you more successful?!?
This is a difficult question, but I think it has an answer. A complex, multifactorial answer, but an answer.
One factor we have to once again come back to is akrasia2. I find akrasia in myself and others to be the most important limiting factor to our success. Think of that phrase "limiting factor" formally, the way you'd think of the limiting reagent in chemistry. When there's a limiting reagent, it doesn't matter how much more of the other reagents you add, the reaction's not going to make any more product. Rational decisions are practically useless without the willpower to carry them out. If our limiting reagent is willpower and not rationality, throwing truckloads of rationality into our brains isn't going to increase success very much.
This is a very large part of the story, but not the whole story. If I was rational enough to pick only stocks that would go up, I'd become successful regardless of how little willpower I had, as long as it was enough to pick up the phone and call my broker.
So the second factor is that most people are rational enough for their own purposes. Oh, they go on wild flights of fancy when discussing politics or religion or philosophy, but when it comes to business they suddenly become cold and calculating. This relates to Robin Hanson on Near and Far modes of thinking. Near Mode thinking is actually pretty good at a lot of things, and Near Mode thinking is the thinking whose accuracy gives us practical benefits.
And - when I was young, I used to watch The Journey of Allen Strange on Nickleodeon. It was a children's show about this alien who came to Earth and lived with these kids. I remember one scene where Allen the Alien was watching the kids play pool. "That's amazing," Allen told them. "I could never calculate differential equations in my head that quickly." The kids had to convince him that "it's in the arm, not the head" - that even though the movement of the balls is governed by differential equations, humans don't actually calculate the equations each time they play. They just move their arm in a way that feels right. If Allen had been smarter, he could have explained that the kids were doing some very impressive mathematics on a subconscious level that produced their arm's perception of "feeling right". But the kids' point still stands; even though in theory explicit mathematics will produce better results than eyeballing it, in practice you can't become a good pool player just by studying calculus.
A lot of human rationality follows the same pattern. Isaac Newton is frequently named as a guy who knew no formal theories of science or rationality, who was hopelessly irrational in his philosophical beliefs and his personal life, but who is still widely and justifiably considered the greatest scientist who ever lived. Would Newton have gone even further if he'd known Bayes theory? Probably it would've been like telling the world pool champion to try using more calculus in his shots: not a pretty sight.
Yes, yes, beisutsukai should be able to develop quantum gravity in a month and so on. But until someone on Less Wrong actually goes and does it, that story sounds a lot like when Alfred Korzybski claimed that World War Two could have been prevented if everyone had just used more General Semantics.
And then there's just plain noise. Your success in the world depends on things ranging from your hairstyle to your height to your social skills to your IQ score to cognitive constructs psychologists don't even have names for yet. X-Rationality can help you succeed. But so can excellent fashion sense. It's not clear in real-world terms that x-rationality has more of an effect than fashion. And don't dismiss that with "A good x-rationalist will know if fashion is important, and study fashion." A good normal rationalist could do that too; it's not a specific advantage of x-rationalism, just of having a general rational outlook. And having a general rational outlook, as I mentioned before, is limited in its effectiveness by poor application and akrasia.
I no longer believe mastering all these Overcoming Bias and Less Wrong techniques will turn me into Anasûrimbor Kellhus or John Galt. I no longer even believe mastering all these Overcoming Bias techniques will turn me into Eliezer Yudkowsky (who, as his writings from 2001 indicate, had developed his characteristic level of awesomeness before he became interested in x-rationality at all)3. I think it may help me succeed in life a little, but I think the correlation between x-rationality and success is probably closer to 0.1 than to 1. Maybe 0.2 in some businesses like finance, but people in finance tend to know this and use specially developed x-rationalist techniques on the job already without making it a lifestyle commitment. I think it was primarily a Happy Death Spiral around how wonderfully super-awesome x-rationality was that made me once think otherwise.
And this is why I am not so impressed by Eliezer's claim that an x-rationality instructor should be successful in their non-rationality life. Yes, there probably are some x-rationalists who will also be successful people. But again, correlation 0.1. Stop saying only practically successful people could be good x-rationality teachers! Stop saying we need to start having huge real-life victories or our art is useless! Stop calling x-rationality the Art of Winning! Stop saying I must be engaged in some sort of weird signalling effort for saying I'm here because I like mental clarity instead of because I want to be the next Bill Gates! It trivializes the very virtues that brought most of us to Overcoming Bias, and replaces them with what sounds a lot like a pitch for some weird self-help cult...

...but you will disagree with me. And we are both aspiring rationalists, and therefore we resolve disagreements by experiments. I propose one.
For the next time period - a week, a month, whatever - take special note of every decision you make. By "decision", I don't mean the decision to get up in the morning, I mean the sort that's made on a conscious level and requires at least a few seconds' serious thought. Make a tick mark, literal or mental, so you can count how many of these there are.
Then note whether you make that decision rationally. If yes, also record whether you made that decision x-rationally. I don't just mean you spent a brief second thinking about whether any biases might have affected your choice. I mean one where you think there's a serious (let's arbitrarily say 33%) chance that using x-rationality instead of normal rationality actually changed the result of your decision.
Finally, note whether, once you came to the rational conclusion, you actually followed it. This is not a trivial matter. For example, before writing this blog post I wondered briefly whether I should use the time studying instead, used normal (but not x-) rationality to determine that yes, I should, and then proceeded to write this anyway. And if you get that far, note whether your x-rational decisions tend to turn out particularly well.
This experiment seems easy to rig4; merely doing it should increase your level of conscious rational decisions quite a bit. And yet I have been trying it for the past few days, and the results have not been pretty. Not pretty at all. Not only do I make fewer conscious decisions than I thought, but the ones I do make I rarely apply even the slightest modicum of rationality to, and the ones I apply rationality to it's practically never x-rationality, and when I do apply everything I've got I don't seem to follow those decisions too consistently.
I'm not so great a rationalist anyway, and I may be especially bad at this. So I'm interested in hearing how different your results are. Just don't rig it. If you find yourself using x-rationality twenty times more often than you were when you weren't performing the experiment, you're rigging it, consciously or otherwise5.
Eliezer writes:
The novice goes astray and says, "The Art failed me."
The master goes astray and says, "I failed my Art."
Yet one way to fail your Art is to expect more of it than it can deliver. No matter how good a swimmer you are, you will not be able to cross the Pacific. This is not to say crossing the Pacific is impossible. It just means it will require a different sort of thinking than the one you've been using thus far. Perhaps there are developments of the Art of Rationality or its associated Arts that can turn us into a Kellhus or a Galt, but they will not be reached by trying to overcome biases really really hard.
Footnotes:
1: Specifically, reading Overcoming Bias convinced me to study evolutionary psychology in some depth, which has been useful in social situations. As far as I know. I'd probably be biased into thinking it had been even if it hadn't, because I like evo psych and it's very hard to measure.
2: Eliezer considers fighting akrasia to be part of the art of rationality; he compares it to "kicking" to our "punching". I'm not sure why he considers them to be the same Art rather than two related Arts.
3: This is actually an important point. I think there are probably quite a few smart, successful people who develop an interest in x-rationality, but I can't think of any people who started out merely above-average, developed an interest in x-rationality, and then became smart and successful because of that x-rationality.
4: This is a terribly controlled experiment, and the only way its data can be meaningfully interpreted at all is through what one of my professors called the "ocular trauma test" - when the data hits you between the eyes. If people claim they always follow their rational decisions, I think I will be more likely to interpret it as lack of enough cognitive self-consciousness to notice when they're doing something irrational than an honest lack of irrationality.
5: In which case it will have ceased to be an experiment and become a technique instead. I've noticed this happening a lot over the past few days, and I may continue doing it.
I’m partly echoing badger here, but it’s worth distinguishing between three possible claims:
(1) An “art of rationality” that we do not yet have, but that we could plausibly develop with experimentation, measurements, community, etc., can help people.
(2) The “art of rationality” that one can obtain by reading OB/LW and trying to really apply its contents to one’s life, can help people.
(3) The “art of rationality” that one is likely to accidentally obtain by reading articles about it, e.g. on OB/LW, and seeing what happens to rubs off, can help people.
There are also different notions of “help people” that are worth distinguishing. I’ll share my anticipations for each separately. Yvain or others, tell me where your anticipations match or differ.
Regarding claim (3):
My impression is that even the art of rationality one obtains by reading articles about it for entertainment, does have some positive effects on the accuracy of peoples’ beliefs. A couple people reported leaving their religions. Many of us have probably discarded random political or other opinions that we had due to social signaling or happenstance. Yvain and others report “clarity-of-mind benefits”. I’d give reasonable odds that there’s somewhat more benefit than this -- some unreliable improvement in peoples’ occasional, major, practical decisions, e.g. about which career track to pursue, and some unreliable improvement in peoples’ ability to see past their own rationalizations in interpersonal conflicts -- but (at least with hindsight bias?) probably no improvements in practical skills large enough to show up on Vladimir Nesov’s poll. Does anyone’s anticipations differ, here?
Regarding claim (2):
I’d a priori expect better effects from attempts to really practice rationality, and to integrate its thinking skills into one’s bones, than from enjoying chatting about rationality from time to time. A community that reads articles about skateboarding, and discusses skateboarding, will probably still fall over when they try to skateboard twenty feet unless they’ve also actually spent time on skateboards.
As to the empirical data: who here has in fact practiced (2) (e.g., has tried to integrate x-rationality into their actual practical decision-making, as in Yvain’s experiment/technique, or has used x-rationality to make major life decisions, or has spent time listing out their strengths and weaknesses as a rationalist with specific thinking habits that they really work to integrate in different weeks, or etc.)? This is a real question; I’d love data. Eliezer is an obvious example; Yvain cites the impressiveness of Eliezer’s 2001 writings as counter-evidence (and it is some counter-evidence), but: (1) Eliezer, in 2001, had already spent a lot of time learning rationality (though without the heuristics and biases literature); and (2) Eliezer was at that time busy with a course of action that, as he now understands things, would have tended to destroy the world rather than to save it. Due to insufficient rationality, apparently.
I’ve practiced a fair amount of (2), but much less than I could imagine some practicing; and, as I noted in the comment Yvain cited, it seems to have done me some good. Broadly similar results for the handful of others I know who try to get rationality into their bones. Less impressive than I’d like, but I tend to interpret this a a sign we should spend more time on skateboards, and I anticipate that we’ll see more real improvement as we do.
The most important actual helps involve that topic we’re not supposed to discuss here until May, but I’d say we were able to choose a much higher-impact way to help the world than people without x-rationality standardly choose, and that we’re able to actually think usefully about a subject where most conversations degenerate into storytelling, availability heuristics, attaching overmuch weight to specific conjunctions, etc. Which, if there’s any non-negligible chance we’re right, is immensely practical. But we’re also somewhat better at strategicness about actually exercising, about using social interaction patterns that work better than the ones we were accidentally using previously (though far from as well as the ones the best people use), about choosing college or career tracks that have better expected results, etc.
Folks with more data here (positive or negative), please share.
Regarding claim (1):
I guess I wouldn’t be surprised by anything from “massive practical help, at least from particular skilled/lucky dojos that get on good tracks” to “not much help at all”. But if we do get “not much help at all”, I’ll feel like there was a thing we could have done, and we didn’t manage to do it. There are loads of ridiculously stupid kinds of decision-making that most people do, and it would be strange if there were no way we could get visible practical benefit from improving on that. Details in later comments.
I agree with almost everything here, with the following caveats:
I. The practical benefits we get from (3) are (I think I'm agreeing with you here) likely to be so small as to be difficult to measure informally; i.e. anyone who claims to have noticed a specific improvement is as likely to be imagining it as really improving. Probably some effects that could be measured in a formal experiment with a very large sample size, but this is not what we have been doing.
II. (2) shows promise but is not something I see discussed very often on Overcoming Bias or Less ... (read more)
