A recent study suggests that unattractive individuals commit more crime than people who are average or good looking. Researchers from the University of Colorado and Georgia State University determined this based on a survey of 15,000 teenagers interviewed in 1994 and again in 1997 and 2002. From the Washington Post:

Cute guys were uniformly less likely than averages would indicate to have committed seven crimes including burglary and selling drugs, while the unhandsome were consistently more likely to have broken the law.

Very attractive high school girls were less likely to commit six of the seven crimes, while those rated unattractive were more likely to have done six of seven, controlling for personal and family characteristics known to be associated with criminal behavior…

Other studies have shown that unattractive men and women are less likely to be hired, and that they earn less money, than the better-looking. Such inferior circumstances may steer some to crime, (the researchers) suggest. They also report that more attractive students have better grades and more polished social skills, which means they graduate with a greater chance of staying out of trouble.
