From Paul Graham: I think that this is much more of the case than actively discouraging boys from being smart. The thing that really puzzles me is the mentality of girls. I knew a lot of girls in high school who busted their asses to get good grades. They did so in order to get into a good college... and then majored in philosophy, communications, or English. Maybe it's just my own utilitarian bias, but I can't imagine busting my ass to get into Cornell or Brown and not majoring in something that could become a career in and of itself. The really cynical part of me thinks that they get into good colleges to meet and marry the guys who are going to said good colleges. This is sexist, but I'm wondering how much of it is actually true.
