许多关于两极分化和选择性曝光的文献都假定互联网加剧了媒体和公民的分裂。然而，这忽视了社交媒体的广泛使用如何改变新闻消费。社交媒体为读者提供了来自不同来源的故事的选择，这些故事来自政治上不同的个人，在强调社会价值而不是党派关系的背景下推荐。基于现有的新闻选择性模型，强调信息效用，我们假设社交媒体的独特功能，社会代言，触发几个决策建议效用。在两个实验中，我们证明，更强的社会认可增加的概率，人们选择的内容，他们的存在减少党派选择性暴露的水平难以区分的机会。
Much of the literature on polarization and selective exposure presumes that the internet exacerbates the fragmentation of the media and the citizenry. Yet this ignores how the widespread use of social media changes news consumption. Social media provide readers a choice of stories from different sources that come recommended from politically heterogeneous individuals, in a context that emphasizes social value over partisan affiliation. Building on existing models of news selectivity to emphasize information utility, we hypothesize that social media's distinctive feature, social endorsements, trigger several decision heuristics that suggest utility. In two experiments, we demonstrate that stronger social endorsements increase the probability that people select content and that their presence reduces partisan selective exposure to levels indistinguishable from chance.
