"I think a highly rational person would have high moral uncertainty at this point and not necessarily be described as "altruistic."

“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 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.”

“In other words, when I say "what's the evidence for that?", it's not that I don't trust your rationality , but I just can't deduce what evidence you must have observed from your probability declaration alone even if you were fully rational.”

“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 , 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.”

“I think status is in fact a significant motivation even for me, and even the more "pure" motivations like intellectual curiosity can in some sense be traced back to status. It seems unlikely that would have been developed without the existence of forums like extropians, everything-list, and LW, for reasons of both motivation and feedback/collaboration.”

“I don't like playing politics, I don't like having bosses and being told what to do, I don't like competition, I have no desire to manage other people, so I've instinctively avoided or quickly left any places that were even remotely maze-like.”

“I typically find myself wanting to verify every single fact or idea that I hadn't heard of before, and say either "hold on, I need to think about that for a few minutes" or "let me check that on Google/Wikipedia". In actual conversation I'd suppress this because I suspect the other person will quickly find it extremely annoying. I just think to myself "I'll try to remember what he's saying and check it out later", but of course I don't have such a good memory.”
