Here are the findings from a study called “Smart Teens Don’t Have Sex (or Kiss Much Either)” :
Students with IQs above 100 and below 70 were significantly less likely to have had intercourse than those in between. Each additional point of IQ increased the odds of virginity by 2.7% for males and 1.7% for females. It’s not just home runs they’re talking about, either: a higher IQ decreased the likelihood of romantic contact in any sense, from holding hands to kissing, across the board.
The blog Gene Expression points to a 2001 campus sex survey to illustrate that this trend doesn’t end with high school, though it looks at institutions and majors rather than IQ scores. For instance:
By age 19, 87% of college students have had sex. At MIT, it’s only 51%. (Furthermore, only 65% of MIT graduate students have had sex.) At Wellesley College, 0% of studio art majors were virgins, but 83% of biochem and math majors were.
A simple google search produced plenty more material on this, in case you should be interested i am willing to provide it.
