Corporate board gender quotas and IQ trends

Here's Jaclyn Friedman quoted in a recent National Post article on whether or not gender quotas should be imposed on corporate boards (emphasis mine):

There’s also this assumption that when you have a quota system, all of these less talented and less qualified women are going to jump the line. But in reality, that’s an incredibly sexist assumption because it assumes that there is a much larger pool of qualified men than women, which is ridiculous.

One thing that she doesn't account for are differences in IQ which it seems can be messed around with through the educational system. Just last year it was announced that the average female IQ is now higher than the average male IQ whereas the reverse was previously the case. Another thing to note is that the standard deviation of male IQs was higher than amongst female IQs, though this too may be changing. Given those parameters it wouldn't seem too surprising that you'd currently find "a much larger pool of qualified men than women" at the high-IQ ranges though over time you might expect that to change as new generations come along.

There's of course also the issue of the amount of time devoted to working and the association of this with the development of expertise, with men still typically working longer and with fewer interruptions than women. One slightly interesting thing to note is that despite the university system now being majority female, the majors requiring the most study time are still majority male - the exception to this is actually the majors that I'd expect you'd be most likely to find on corporate boards. i.e. Business majors average the lowest amounts of study-time although business students seem to spend far more hours working for pay than other majors which I guess is another way to accumulate expertise.

And, of course, there are the studies both for and against such quotas. Personally I've got no objection to women on corporate boards, but I do object to quotas.
