Do ugly people commit more crime? Yes, statistically speaking anyhow.
Before you chalk this one up as the discredited pseudoscience of physiognomy rearing its ugly head, consider the argument behind a paper by Georgia State University economist (and dashingly handsome guy) Erdal Tekin:
Ugly people are more likely to break the law. This is the statistically based conclusion in a paper published in The Review of Economics and Statistics entitled Ugly Criminals [...]
This takes us to the modern Ugly Criminals study, which is subtler than it might seem. It is based on an anonymous questionnaire combined with equally anonymous ratings of the subject’s attractiveness. It shows a small but significant correlation between attractiveness, or the lack of it, and criminality. The most unattractive segment are 1.5 per cent more likely to have committed robbery, 2.2 per cent more likely to have committed assault, and 3 per cent more likely to have sold drugs. Or to have been caught doing so, at any rate.
The authors note previous work showing how more attractive people are more successful in their careers and earn more. This puts less attractive people at a disadvantage in the world of work and nudges them towards criminal alternatives. In addition, less attract ive people suffer socially, make fewer friends and build less of what the authors call “human capital”. They are therefore not as sympathetic to others and have less of an investment in society. This effect is far more pronounced in females, suggesting that they are judged on their appearance to a much greater degree.

But it's still a stupid study.
