There can be little doubt that some societies are more steeped in violence than others, even controlling for obvious factors like income levels and education. The US homicide rate is roughly four times that of comparable societies in Western Europe, and Latin America’s homicide rates are even higher than in the US (and dramatically higher than Asian countries at roughly the same income level).
毫无疑问，即使控制了收入水平和教育等显而易见的因素，某些社仍比其他社会更具暴力倾向。美国杀人率大约是可比西欧社会的四倍，而拉美的杀人率比美国还高（比收入水平相当的亚洲高得多）。美国和拉美杀人率如此之高的原因是什么？
