选择性接触假设认为，人们渴望获得志同道合的信息，而回避与他们的信仰相冲突的信息，这对政治生活有负面影响。然而，尽管经过了几十年的研究，这一假设在理论上仍然很有希望，但在经验上却很难检验。我们研究了Facebook上分享的新闻文章，并研究了社交媒体中是否存在选择性曝光。我们发现了一个具体的证据表明，用户主要分享志同道合的新闻文章，避免冲突的，和游击队更有可能这样做。要在社交媒体上构建对抗党派偏见的工具，首先需要能够识别党派用户。我们将表明，这些用户不能从普通用户中区分出来，因为这两个子组没有显示出任何人口统计学差异。
The hypothesis of selective exposure assumes that people crave like-minded information and eschew information that conflicts with their beliefs, and that has negative consequences on political life. Yet, despite decades of research, this hypothesis remains theoretically promising but empirically difficult to test. We look into news articles shared on Facebook and examine whether selective exposure exists or not in social media. We find a concrete evidence for a tendency that users predominantly share like-minded news articles and avoid conflicting ones, and partisans are more likely to do that. Building tools to counter partisanship on social media would require the ability to identify partisan users first. We will show that those users cannot be distinguished from the average user as the two subgroups do not show any demographic difference.
