The Math Sex Gap Revisited
With his characteristic wit, La Griffe du Lion destroys some recent academic studies. He argues that relative to women, men have (A) a higher mean math ability; (B) a greater variance in math ability, meaning that they’re more likely to be very good or very bad at it, rather than average; and (C) a higher likelihood of entering math fields when they’re qualified for them. Add these together, and even absent discrimination, there will be few women in math fields.
I’d recommend reading at least the first few sections; the calculations get pretty intense toward the end, and lost me.
