Nerds rejoice: Braininess boosts likelihood of sex

Oct. 6, 2008— -- Lonely men ought to flaunt their copies of New Scientist. Women looking for both one-night stands and long-term relationships go for geniuses over dumb jocks, according to a new study of hundreds of university students.

"Women want the best of both worlds. Not only a physically attractive man, but somebody in the long term who can provide for them," says Mark Prokosch, an evolutionary psychologist at Elon University in North Carolina, who led the study.

To many women, a smart man will appeal because he is likely to be clever enough to keep his family afloat. But he may also pass on "good" genes to his children, say Prokosch and his colleagues at the University of California, Davis.

Rather than ask women to rate qualities they seek in men, as other studies had done, Prokosch's team asked 15 college men to perform a series of tasks on camera.

The volunteers read news reports, explained why they would be a good date, and what would be the ramifications of the discovery of life on Mars. They also threw and caught a Frisbee to parade their physical appeal. Each potential suitor also took a quantitative test of verbal intelligence.

Smart is sexyMore than 200 women watched a series of these videos before rating each man's intelligence, attractiveness, creativity and appeal for a short-term or long-term relationship.

While the difference between short- and long-term mates may amount to a boozy decision students face each weekend, it has some evolutionary significance, Prokosch says. In potential husbands, women look for signs that a man might be a good provider and father. In one-night stands, women are on the prowl for little more than good genes, not to mention a good time.

Women proved to be decent judges of intelligence, with their scores generally matching each man's intelligence test results.

As for picking a bed-mate, the men's actual smartness proved a reliable indicator of their appeal for both brief hook-ups and serious relationships – which came as something of a surprise. Other studies have suggested that, for women anticipating short-term relationships, a man's braininess isn't foremost in their minds.
