I'm not sure how much you mean by the doing without a kick analogy. If you mean, for example, that a rationalist should overcome something like social anxiety that impedes his research career by developing techniques from scratch rather than engaging in something like cognitive behavioral therapy, then I disagree. Ditto for the other sorts of psychological problems I mentioned.
The reason is not that I think you couldn't address anything from first principles, building up techniques as you go, but that this would be hugely inefficient, like developing calculus from first principles rather than studying a textbook.
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
