Brains go with beauty
[S]everal reviews of the literature have concluded that there is indeed a small, positive relationship between beauty and brains. Most recently, the evolutionary psychologist Satoshi Kanazawa pulled huge datasets from two sources—the National Child Development Study in the United Kingdom (including 17,000 people born in 1958), and the National Longitudinal Study of Adolescent Health in the United States (including 21,000 people born around 1980)—both of which included ratings of physical attractiveness and scores on standard intelligence tests. When Kanazawa analyzed the numbers, he found the two were related: In the U.K., for example, attractive children have an additional 12.4 points of IQ, on average. The relationship held even when he controlled for family background, race, and body size.
