‘Everybody’s doing it’: on the persistence of bad social norms
通过实验研究信息如何影响不良社会规范的持续存在，发现多元无知是关键因素，且社会互动强度对规范持续很重要，有助于理解并设计干预措施。
Abstract We investigate how information about the preferences of others affects the persistence of ‘bad’ social norms. One view is that bad norms thrive even when people are informed of the preferences of others, since the bad norm is an equilibrium of a coordination game. The other view is based on pluralistic ignorance, in which uncertainty about others’ preferences is crucial. In an experiment, we find clear support for the pluralistic ignorance perspective . In addition, the strength of social interactions is important for a bad norm to persist. These findings help in understanding the causes of such bad norms, and in designing interventions to change them.
