As reported by the NY Daily News and TIME magazine, a new scientific study has been released which finds beautiful people are more likely to be smarter than their aesthetically challenged rivals. The study led by Satoshi Kanazawa of the London School of Economics found handsome men averaged 13.6 points higher and beautiful women average 11.4 points higher on IQ tests. Yes, true intelligence encompasses more than analytical skills (there's also emotional, social, linguistic, and creative intelligence), but nonetheless beautiful people are better equipped at intellectualisms than ugly ducklings.
The Daily News reported there were 50,000 participants. I pulled up the abstract of the paper, the contents are behind a paywall, but United Press International reports:

In other words, this was not some quickie Internet poll and general intelligence was evaluated. In searching for a possible explanation of the beautiful intelligence factor, I found a previous abstract by Satoshi Kanazawa from 2004:[the] longitudinal study tracked 17,419 British babies all born during one week in 1958. The study subjects were interviewed in 1965, in 1969, in 1974, in 1981, in 1991, in 1999 to 2000 and in 2004 to 2005. Several intelligence tests are taken. At ages 7 and 11, the teacher of each study subject is asked to describe the child's physical appearance.
The National Longitudinal Study of Adolescent Health involves 20,745 U.S. students who were personally interviewed at home in 1994 to 1995, 1996 and 2001 to 2002. They were also given intelligence tests. The interviewer rated the respondent's physical attractiveness on a five-point ordinal scale.
The British sample has one of the best measures of general intelligence in all survey data, but a comparatively weak measure of physical attractiveness. In contrast, the American sample has a stronger measure of physical attractiveness, but a comparatively weak measure of general intelligence, Kanazawa says.
Empirical studies demonstrate that individuals perceive physically attractive others to be more intelligent than physically unattractive others. While most researchers dismiss this perception as a “bias” or “stereotype,” we contend that individuals have this perception because beautiful people indeed are more intelligent. The conclusion that beautiful people are more intelligent follows from four assumptions. (1) Men who are more intelligent are more likely to attain higher status than men who are less intelligent. (2) Higher-status men are more likely to mate with more beautiful women than lower-status men. (3) Intelligence is heritable. (4) Beauty is heritable. If all four assumptions are empirically true, then the conclusion that beautiful people are more intelligent is logically true, making it a proven theorem. We present empirical evidence for each of the four assumptions. While we concentrate on the relationship between beauty and intelligence in this paper, our evolutionary psychological explanation can account for a correlation between physical attractiveness and any other heritable trait that helps men attain higher status (such as aggression and social skills).
