From Extreme to Mainstream: The Erosion of Social Norms
通过两个实验，研究了特朗普崛起和胜选如何使人们更愿意公开表达仇外观点，并发现当某种观点更流行时，表达者受到的负面评价会减少。
Social norms, usually persistent, can change quickly when new public information arrives, such as a surprising election outcome. People may become more inclined to express views or take actions previously perceived as stigmatized and may judge others less negatively for doing so. We examine this possibility using two experiments. We first show via revealed preference experiments that Donald Trump’s rise in popularity and eventual victory increased individuals’ willingness to publicly express xenophobic views. We then show that individuals are sanctioned less negatively if they publicly expressed a xenophobic view in an environment where that view is more popular.
