Don't tell me anecdotal evidence about individuals. It is a fact of Nature that the outliers on the intelligence bell curve are overwhelmingly male. Our outliers on the high end are being systematically suppressed. This has consequences, and will have more consequences as time goes on.
It is not a fact of nature that the outliers are overwhelmingly male. Without ego I may say that as a holder of a mathematics PhD I am an outlier on the bell curve -- and so are all the other recent PhDs in math, 29% of whom are female.
And I don't buy the claim that male outliers are being suppressed: the number of Americans getting PhDs in math has fluctuated in the 400 - 600 range per year for decades, 70-75% male throughout.
