美国心理学家菲利普·津巴多于1969年进行了一项实验,把两辆一模一样的汽车中的一辆停在加州某处中产阶级社区,另一辆停在比较杂乱的地区。他把停在杂乱地区车辆的车牌摘掉、顶棚打开,结果当天车辆就被偷走。而放在中产地区的那辆一个星期后也是安然无恙,但当用锤子把那辆车的玻璃敲了个大洞后,仅仅几个小时后就不见了。以这项试验为基础,政治学家威尔逊和犯罪学家凯琳提出了一个“破窗理论”:如果有人打坏了一个建筑物的窗户玻璃,而这扇窗户又得不到及 American psychologist Philip Zimbardo conducted an experiment in 1969, stopping one of two identical cars in a middle-class neighborhood somewhere in California and the other in more cluttered areas.

A week after the middle-class car was safe, but a few hours later it was gone when the glass of the car was knocked down by a hammer.
