Our happy hour fact to amaze your drinking buddies with.

Attractive people have significantly higher I.Q.s than their frumpier counterparts.

Satoshi Kanazawa, an evolutionary psychologist at the London School of Economics, had 52,000 people from the United States and the United Kingdom both rated on their looks and given an I.Q. test. Attractive men scored 13.6 points above average on the I.Q. test, and attractive women beat the mean by 11.4 points. The study controlled for class, body size and health.

Kanazawa's explanation for why attractiveness and I.Q. are correlated is that smart men tend achieve high status, allowing them to marry attractive women, and thereby passing both good looks and intelligence to their children.
