However, here we see that there is finer pattern behind this when you break it down. What is actually happening is that fertility is highly dysgenic by IQ for liberal men (for whom indeed, the smartest category of such men here – roughly IQ 115+ – about 50% leave no descendants); is slightly dysgenic for moderate men; and is slightly eugenic for conservative men. … While fertility for conservative White women appears to be slightly eugenic, it is not because the smartest women are having most of the children. Rather, it’s the ones with only somewhat above average intelligence – the Sarah Palins and Michele Bachmanns of the country – who are having the most children, with 10% having 4 or more. Since among conservative men, it is the smartest ones who are having most of the children, this suggests that these men are married to women who are quite a bit less intelligent than their husbands (albeit, still above average in intelligence).
Continuing my ongoing investigation into fertility, I wanted to take another look at who’s having children. This post will look at fertility from a different angle: the spread in fertility by sex, IQ, political orientation, and education.
I was prompted to this by a recent article describing parenthood in Norway. It found that a fifth to a quarter of men from the Boom generation and the generation following had no children.
This finding is highly similar to what I found previously for the U.S.
