I don't know who this guy you're talking about is but you can look at the grade distributions men and women have in school and see a pretty obvious difference.

I don't know who this guy you're talking about is but you can look at the grade distributions men and women have in school and see a pretty obvious difference. You could argue there's an environmental reason men have a more shallow (wider variance) distribution while women tend to have a narrower one with a higher mean but I haven't heard a good argument for it. At the end of the day this of course says very little about individuals, I think that's the mistake people make looking at these sorts of statistics and ideas (and why everyone gets so hung up on the idea that there are mental differences between the sexes.) Even individual performance academically says almost nothing about their ability to perform professionally IMO.
