Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man.

Truth is much too complicated to allow anything but approximations.
— John Von Neumann
I think that most people, including rationalists, have significant psychological problems that interfere with their happiness in life and impair their rationality and their pursuit of rationality. What we think of as normal is very dysfunctional, and it is dysfunctional in many more ways than just being irrational and subject to cognitive biases.
I think furthermore that before devoting yourself to rationality at the near exclusion of other types of self-improvement, you should devote some serious effort to overcoming the more mundane psychological problems such as being overly attached to material trinkets and measuring your self-worth in material terms, being unaware of your emotions and unable to express your emotions clearly and honestly, having persistent family and relationship problems, having chronic psychosomatic ailments, etc. Without attending to these sorts of issues first (or at the same time), trying to become a rationalist jedi is like trying to get a bodybuilder physique before you’ve fixed your diet and lost the 200 extra pounds you have.
Education is a technology that tries to make up for what the human mind is innately bad at. Children don’t have to go to school to learn how to walk, talk, recognize objects, or remember the personalities of their friends, even though these tasks are much harder than reading, adding, or remembering dates in history. They do have to go to school to learn written language, arithmetic, and science, because those bodies of knowledge and skill were invented too recently for any species-wide knack for them to have evolved.

The most valuable acquisitions in a scientific or technical education are the general-purpose mental tools which remain serviceable for a lifetime. I rate natural language and mathematics as the most important of these tools, and computer science as a third.
George E. Forsythe
It would be an error to suppose that the great discoverer seizes at once upon the truth, or has any unerring method of divining it. In all probability the errors of the great mind exceed in number those of the less vigorous one. Fertility of imagination and abundance of guesses at truth are among the first requisites of discovery; but the erroneous guesses must be many times as numerous as those that prove well founded. The weakest analogies, the most whimsical notions, the most apparently absurd theories, may pass through the teeming brain, and no record remain of more than the hundredth part….

Go down deep enough into anything and you will find mathematics.

If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence.
-- Bertrand Russell
Everything is vague to a degree you do not realize till you have tried to make it precise.
Bertrand Russell
Thinking is skilled work. It is not true that we are naturally endowed with the ability to think clearly and logically—without learning how, or without practicing.… People with untrained minds should no more expect to think clearly and logically than people who have never learned and never practiced can expect to find themselves good carpenters, golfers, bridge-players, or pianists.

I think there is a huge amount of wisdom in the core ideas of Buddhism. self is a convenient fiction and a source of much confusion and suffering; subtle forms of attachment are frequent sources of suffering; meditation can improve attention/concentration and meta-cognitive awareness, and some Buddhist techniques are effective in this regard; our experience in life is much more determined by our mind than we believe; compassion can and should be cultivated.
It’s possible but doesn’t seem very likely, since given the choice between $1M outright or $500 outright, those same people would almost certainly take the $1M.
I think a more likely explanation is that they conceptualize the problem as having to choose between “probably getting $0” and “certainly getting $500″.

In general, we are least aware of what our minds do best.

The opposite intellectual sin to wanting to derive everything from fundamental physics is holism which makes too much of the fact that everything is ultimately connected to everything else. Sure, but scientific progress is made by finding where the connections are weak enough to allow separate theories.
Not that I don’t think your donation is admirable, but I’m curious how you are able to donate your entire bank account without running the risk of not being able to respond to a black-swan event appropriately and your future well-being and ability to donate to SIAI being compromised?
Do you think it’s rational in general for people to donate all their savings to the SIAI?
Is the point about respect for instructors supposed to generalize to instructors of disciplines other than rationality?
If so, what do you make of Nadia Boulanger? Her accomplishments as a musician (or otherwise) are unimpressive relative to those of her students and peers, and yet she is regarded as one of the greatest music teachers ever, and is accorded correspondingly deep respect by music historians, composers, etc. Are they all wrong to respect her so much, or does it not apply to music or this case?
It seems to me that a better formula for determining respect would somehow reflect the respect given to her students which they say is significantly due to her influence as a teacher. For example, if Aaron Copland singles her out as an amazing teacher who profoundly affected his musical life & education, then she deserves some of the respect given to him. And likewise for her many other students who went on to do great things.
There seems to be an implicit underlying belief in this post that teaching is not (or should not be) an end in and of itself, or at least not a worthy one. I think Boulanger and teachers of her caliber show that that’s just not the case.
Survey completed. I cooperated without thinking about it much. I believed that TDT-like reasoning would probably lead a significant number of others to cooperate too, and I felt I should support the group.
