A massive new study in Science journal says girls are equal to boys at math. I agree with that. In fact, I think girls are equal to boys at many things.
But here is the paradox: There are more male nobel laureates, male fields medalists, male artists, male composers, male sculptors, male engineers etc.
I am not making any judgement here. But this seems to show something contrary to what the study is thought to say. I guess the study is specific, i.e. intended just for making conclusions about schoolchildren.
Perhaps there is a diversion later on in their development. Or perhaps there is an involuntary bias to recognize male achievement in the society.
