I agree that it's rational to seek better hair if better hair leads to your goals. I'm trying to point out an inconsistency: that if you claim to be after success in business, and you spend a lot of time reading Less Wrong but very little time worrying over your hair, then either you're not being as rational as you think or you're not as focused on success in business as you think.

I further wonder if some people who read this will make a token attempt to consider getting nice haircuts, not because they're really after real-world success but because they want to be able to continue telling themselves credibly that they're really after real-world success.
