Like father, like son? A note on the intergenerational transmission of IQ scores

Using a large population-based dataset, we estimate a substantial intergenerational transmission of IQ scores; a 10% increase in father's score at age 18 is associated with a 3.2% increase in son's score. This relationship also holds true for various subpopulations. (C) 2009 Elsevier B. V. All rights reserved.
