That is actually what he is trying extra hard to explain that he is _not_ asserting (if you go read the thing).
It's basically what he is spending the first few pages trying to be absolutely clear about. The overlapping normal distribution curves is a very immediate way to visualise it, but an excerpt will have to do:
"Note, I’m not saying that all men differ from all women in the following ways or that these differences are “just.” I’m simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don’t see equal representation of women in tech and leadership. Many of these differences are small and there’s significant overlap between men and women, so you can’t say anything about an individual given these population level distributions."
