Study Finds Link Between High IQ and Waiting on Sex in TeensJuly 1st, 2010 by Mike
A 2000 Study by University of North Carolina – Chapel Hill concluded that more intelligent teenagers are more restrained about sex, and are much less sexually active on the whole than their less-intelligent classmates. In the experiment, 12,000 students between the 7th and 12th grades were polled (in confidence) about their sexual activity, and then given a basic intelligence test. The teenagers who scored higher on the intelligence test consistently reported a much lower level of sexual activity.
Here’s a selection from the study’s abstract summary (emphasis mine)…
RESULTS: Controlling for age, physical maturity, and mother’s education, a significant curvilinear relationship between intelligence and coital status was demonstrated; adolescents at the upper and lower ends of the intelligence distribution were less likely to have sex. Higher intelligence was also associated with postponement of the initiation of the full range of partnered sexual activities. An expanded model incorporating a variety of control and mediator variables was tested to identify mechanisms by which the relationship operates.
CONCLUSIONS: Higher intelligence operates as a protective factor against early sexual activity during adolescence, and lower intelligence, to a point, is a risk factor.
You have to pay for to read the full study, but the abstract is pretty informative. Check it out here: Smart teens don’t have sex (or kiss much either).
