He's referring to a group that is selected based on their intelligence. In that case, it doesn't really matter what the distribution of the larger population is, because you're only talking about a group that is selected for their favorable attributes.

For someone to say that people who are already in a career, that is, already selected for their ability, are less suited because of their sex is kind of absurd.
