It's not obvious to me that after rejecting Pascal's Mugging there is anything left to say about XiXiDu's fears or any reason to reject expected utility maximization(!!!).
Well, in so far as it isn't obvious why Pascal's Mugging should be rejected by a utility maximizer, his fears are legitimate. It may very well be that a utility maximizer will always be subject to some form of possible mugging. If that issue isn't resolved the fact that people are rejecting Pascal's Mugging doesn't help matters.

I fear that the mugger is often our own imagination. If you calculate the expected utility of various outcomes you imagine impossible alternative actions. The alternatives are impossible because you already precommited to choosing the outcome with the largest expected utility. There are three main problems with that:
So after reading SarahC's latest post I noticed that she's gotten a lot out of rationality.
More importantly, she got different things out of it than I have.
Off the top of my head, I've learned...
Where she got...
I've only recently making a habit out of trying new things, and that's been going really well for me. Is there other low hanging fruit that I'm missing?
What cool/important/useful things has rationality gotten you?
