Political Correctness, Social Image, and Information Transmission
通过实验验证了政治正确性压力导致人们在公开场合表达与私下不同的观点，并发现公开言论信息量更低，且听众的幼稚会加剧信息损失。
A prominent argument in the political correctness debate is that people feel pressure to publicly espouse sociopolitical views they do not privately hold, and that such misrepresentations might render public discourse less vibrant and informative. This paper formalizes the argument in terms of social image and evaluates it experimentally in the context of college campuses. The results show that (i) social image concerns drive a wedge between the sensitive sociopolitical attitudes that college students report in private and in public; (ii) public utterances are indeed less informative than private utterances; and (iii) information loss is exacerbated by (partial) audience naïveté.
