In other words, when I say "what's the evidence for that?", it's not that I don't trust your rationality (although of course I don't trust your ratio… - Wei Dai

Part of it, which perhaps you and most other observers are not aware, is that I have enough passive income, and enough dispassion for conventional status signaling, that my marginal utility of money is pretty low compared to my disutility for doing busywork. To put it in perspective, I quit my last regular job in 2002, and stopped doing consulting for that company as well (at $100/hour) a year later when they merged with Microsoft and told me I had to do a bunch of paperwork and be hired by Microsoft's "independent consulting company" in order to continue.

Here's my experience. I applied to just MIT and my state university (University of Washington). I got on MIT's waiting list but was ultimately not accepted, so went to UW. I would certainly have gone to MIT had I been accepted, but my thinking now is that if I did that, I would not have had enough free time in college to write Crypto++ and think about anonymous protocols, Tegmark's multiverse, anthropic reasoning, etc., and these spare-time efforts have probably done more for my "career" than the MIT name or what I might have learned there.

Yes, but I tend not to advertise too much that people should be less certain about their altruism, since it's hard to see how that could be good for me regardless of what my values are or ought to be. I make an exception of this for people who might be in a position to build <nowiki>[</nowiki>a friendly artificial intelligence<nowiki>]</nowiki>, since if they're too confident about altruism then they're likely to be too confident about many other philosophical problems, but even then I don't stress it too much.
