I’m not clear why the authors find this so hard to understand. There are a great many more low-intelligence and high-intelligence men than women. Intelligence in both men and women graphs as a bell cuve, but the male bell curve is wider and shorter, while the female curve is narrower and higher.
That means there are many fewer women on the extreme high intelligence math and science side. I’ve seen studies indicating the male-female ratio in this very small group is in the 10 to 100:1 area.
When we are talking about this tiny group, the average capabilities of the general male and female groups is comprehensively irrelevant.
IOW, average men and women are approximately equal in their ability to do math and science, but it would not be a good idea to bet a lot of money that the next Einstein or Hawking will be a lady.

Don’t worry, the feminazis will find a way to redefine Einstien’s brand of genius so that a woman can qualify.
