>>Both in the British and American samples, physical attractiveness is significantly positively associated with general intelligence, both with and without controls for social class, body size, and health.

Both in the UK and in the US, the association between physical attractiveness and general intelligence is stronger among men than among women. In the UK, physically attractive men have higher IQ by 13.6 points, whereas physically attractive women have higher IQ by 11.4 IQ points.<<

This study is well-done and found no significant correlation, but that is also good news for men looking for beauty AND brains in a bride. You don't have to limit yourself to one of the two traits.

There seems to either be a positive correlation or no correlation.

Very well done, those researchers. The only criticism I can manage is one the researchers raised themselves - their measures of attractiveness are ratings by teachers who know the participants well. Potential halo effect, they called it, but its more than that.

We've all met attractive members of the sex we're attracted to who suddenly become... less attractive on opening their mouths.

But if we accept that their measure of attractiveness is inherently the longer-term and stable form of the concept, then it's an excellent study with strong and robust results.

Interesting...

The other study I posted also assumes halo-effect.
