Do attractive people have higher or lower IQs?

Beauty AND brains? It seems there may be a connection. 

There have been a lot of studies on physical attractiveness and IQ ratio - and more often than not, the attractive people are a tad smarter, as a group. Experts say it’s all about genetic quality. According to the National Longitudinal Study of Adolescent Health, healthier, happier people tend to be more attractive and more intelligent, and chances are their parents were too. They also tend to attract each other. Because both intelligence and physical attractiveness are highly heritable, their children are much more likely to inherit both beauty and brains.
