The deltas between genders are quite a bit smaller than those between nationalities, though!
I mean, sure, I guess you could trigger the proverbial SJWs by pointing out the fact that a US woman is about a third of a standard deviation worse than her male classmates. But it's hard to draw firm conclusions about gender when Chinese and Indian men are at an even larger handicap relative to her.
I mean, I gotta flip this around here: why do you feel like we should be focusing on a small subsignal when the data supports a clearer, more defensible, and more hypothesis-rich conclusion about something else?
