A pair of economists at the Ragnar Frisch Center for Economic Research in Norway has found that men who score higher on IQ tests tend to put off having children longer than men who score lower—and yet they still mange to have more children than their lower-scoring associates. In their study, reported in the journal Biology Letters, Bernt Bratsberg and Ole Rogeberg analyzed population data for males in Norway living between the years 1950 to 1981.
I don’t know that I’m smarter than average, but I do think it was smart of my wife and I to wait until our 30s to have a child.
