Crime is ugly. Does society's treatment of the less attractive make them more likely to commit crimes?:
"I'm too ugly to get a job." -- Daniel Gallagher, a Miami bank robber, after police captured him in 2003
...Not only are physically unattractive teenagers likely to be stay-at-homes on prom night, they're also more likely to grow up to be criminals, say two economists... "We find that unattractive individuals commit more crime in comparison to average-looking ones, and very attractive individuals commit less crime in comparison to those who are average-looking," claim Naci Mocan of the University of Colorado and Erdal Tekin of Georgia State University... 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... controlling for ... characteristics known to be associated with criminal behavior.
Mocan and Tekin aren't sure why criminals tend to be ugly. 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, Mocan and Tekin 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.
