For most ordinary people [...] deeply understand maths is a lot of work. And a bunch of girls don't need to bother. On the other hand, a bunch of boys have nothing better to do and can only hope that studying hard will pay off in the attention of girls down the road. I agree with a little kernel of truth here that says girls are perversely encouraged to just ride on their charisma, but it's a huge fallacy to believe this is somehow the most natural state since people in America are by definition free. They might be politically free, but social pressures and conventions are enormous. Do not make the same mistake evolutionary psychologists make all the time in assuming whatever you see culturally is hard-coded into the human mind. This is probably hard to notice until you start looking at a lot of other countries, where some are even more restrictive but others are way more liberal than the US. Girls being encouraged to do nothing but look pretty and dig for wealthy husbands is not the hallmark of a free society and it is not somehow justifiable by making a hand-wavy statement about the supposed nature of the sexes.
