I think there's an arguable point: Men are more likely to be stupid (defective chromosome and all that), and going into academia today is a really stupid choice. It's stupid in the "high risk, but maybe high but questionable payoff" sense in the same way that wingsuiting is, and there's also a gender gap in wingsuiting too.
