英格兰东北部有一家小咖啡厅,生意不错,只要有空闲,人们都愿意到那里喝上一杯。而且,那里没有收费员,只有一个无人看管的投币箱,箱子上放着价目表,价目表上的图案会不定期变换。慢慢地,人们有了一个有趣的发现——箱子的图案与收到的钱数密切相关:在价目表上画双眼睛后,更多的人向收款箱子投了钱,钱的数目比画花草等其他图案的时候要多得多。后来,这个发现还启发了当地的警察。警察把画着一双双眼睛的海报张贴到全市各处,结果,这项措施与设置明亮的蓝灯获得了同样的效果:极大降低了当地犯罪率。
There is a small coffee shop in northeastern England, a good business, as long as free, people are willing to go there for a drink. Moreover, there is no toll-taker, there is only one unattended coin box, the price list on the box, the price list on the pattern will be changed from time to time. Slowly, one of the most interesting discoveries was that the box pattern was closely related to the amount of money received: after drawing two eyes on the price list, more people cast money into the cash box, And other patterns when much more. Later, this discovery also inspired the local police. The police posted posters with double eyes across the city, and as a result, the measure achieved the same effect as setting a bright blue light: a dramatic reduction in the local crime rate.
