What about the impact of diet? Does not a better childhood diet (as well as a
decrease in childhood diseases) impact resultant IQs? Then again, you also have
the fact that the increase in women with higher education brings the
intelligence of the female into play when mating qualifications are examined.
Prior to highly educated women, there was no standard for comparison for men to
tell the intelligence of one woman from another without more extensive courting
experience. As a result, possibly more intelligent people marry each other now
than in the past...
