Ugly Criminals
研究发现外貌吸引力影响年轻人的犯罪倾向：非常好看的人犯罪率更低，不好看的人更高，这可能是因为劳动力市场对不好看者的惩罚直接激励了犯罪，且高中时期的外貌通过影响人力资本形成间接起作用，但该间接效应仅对女性显著。
Being very attractive reduces a young adult's propensity for criminal activity and being unattractive increases it. Being very attractive is also positively associated with wages and with adult vocabulary test scores, which implies that beauty may have an impact on human capital formation. The results suggest that a labor market penalty provides a direct incentive for unattractive individuals toward criminal activity. The level of beauty in high school is associated with criminal propensity seven to eight years later, which seems to be due to the impact of beauty in high school on human capital formation, although this avenue seems to be effective for females only. © 2010 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
