IQ link to virginity

As if the normal perception that 'geeks and the stupid don't get any' wasn't enough, there is now scientific evidence which validates this stereotype. Recent studies in the US on sexual activity among adolescents and young adults show that being an 'average Joe' may have benefits outside of the classroom.

The studies show that female and male adolescents with an IQ score either below 70 or above 110 are more likely to be virgins.

Adolescents with IQ scores ranging from 70 to 110 had the lowest probability of virginity, according to two researchers from the University of North Carolina at Chapel Hill. The average IQ score is 90 to 110.

Mariah Mantsun Cheng, a research associate, and J Richard Udry, professor of maternal and child health and sociology, both from the University of North Carolina at Chapel Hill, conducted the study. They discovered that 39.8% of boys with an average IQ score have had sex while 29.2% of boys with an IQ above 110 have had sex.

They also found that 63.3% of adolescent men and 81.6% of women with IQ scores below average have never had sex and most have had fewer experiences of romantic attraction.

Another study in Gene Expression Magazine entitled 'Intercourse and Intelligence' confirms this data, citing research that shows a bell-shaped relationship between IQ scores and sex. According to the research, an adolescent with an IQ score of 100 was 1.5 to 5 times more likely to have had intercourse than an adolescent with an above average score of about 120 to 130.

The Centres for Disease Control and Prevention (CDC) along with nationwide university studies support this research. The CDC states that by age 19, 80% of men and 75% of women, in the US, lose their virginity.

According to a survey held by Counterpoint Magazine at Wellesley College and the Massachusetts Institute of Technology (MIT), 60% of undergraduates at Wellesley are virgins and 47% of undergraduates at MIT are currently virgins.

The study at Wellesley also broke the research down by majors. It found that no studio art majors were virgins while 72% of biology majors and 83% of biochemistry and math majors were virgins.

Cheng said the research also indicated that boys with lower IQ scores are more likely to be attracted to the same sex compared with average boys. "While the majority of adolescents with lower cognitive abilities have not had sex," Cheng said, "among those who are sexually active, especially for girls, are much less likely to use contraceptives, having a higher risk of pregnancy as well."
