More data on IQ and fertility

: Darwinian Individualist digs up some data from the long-running General Social Survey, which gives a 10 word vocabulary quiz to each participant. This serves as a crude IQ test. He looked at 21,625 people of all races over the age of 35. The mean and modal score right was 6 words out of 10.

People who got only 1 word right out of 10 averaged 2.99 children, with their first child born when they were 21.24 years old. Brainiacs who got all 10 words right averaged 1.95 children, with their first child born at 26.77.
