美国心理学家詹巴斗曾进行过一项有趣的试验:把两辆一模一样的汽车分别停放在两个不同的街区。其中一辆完好无损,停放在帕罗阿尔托的中产阶级社区;而另一辆,摘掉车牌、打开顶棚,停放在相对杂乱的布朗克斯街区。结果怎样呢?停在中产阶级社区的那一辆,过了一个星期还完好无损;而打开顶棚的那一辆,不到一天就被偷走了。后来,詹巴斗把完好无损的那辆汽车敲碎一块玻 An interesting experiment has been conducted by American psychologist Zamboangal: parking two identical cars in two different neighborhoods. One of them was intact and parked in a middle-class community in Palo Alto, while the other, removing the license plate, unclosed and parked in the relatively cluttered Bronx neighborhood. What happened? The car parked in the middle-class community remained intact for a week and the one that opened the roof was stolen in less than a day. Later, Giancarlo knocked the glass of the car intact
