This study explored Facebook users’ hostile perceptions of shared news content and its relationship with their political participation. This study conducted an online experiment with a 3 (news slant: pro-attitudinal, neutral, counter-attitudinal) × 3 (news sharer: in-group, neutral, out-group) between-subjects design. This experiment was administered in the context of the abortion issue in South Korea. Consistent with the hostile media effect, the news slant (pro-attitudinal, counter-attitudinal) of shared news content was found to influence Facebook users’ hostile perceptions of shared news content. Out-group sharers also significantly affected their hostile perceptions of shared news content. However, in-group sharers did not. Furthermore, the effect of Facebook users’ hostile perceptions of shared news content on their willingness for political participation was moderated by their prior minority perception in the general society. Only for Facebook users with high levels of prior minority perception in the general society, their hostile perceptions of shared news content appeared to encourage their political engagement. The implications of these findings were discussed.

本研究探讨了 Facebook 用户对共享新闻内容的敌意看法及其与政治参与的关系。本研究进行了一项在线实验，采用 3（新闻倾向：亲态度、中立、反态度）×3（新闻分享者：组内、中立、组外）之间的被试设计。该实验是在韩国堕胎问题的背景下进行的。与敌对媒体效应一致，我们发现共享新闻内容的新闻倾向（亲态度、反态度）会影响 Facebook 用户对共享新闻内容的敌意看法。外群体共享者也显着影响了他们对共享新闻内容的敌意看法。但是，组内共享者没有。此外，Facebook 用户对共享新闻内容的敌意看法对其政治参与意愿的影响受到他们先前在一般社会中的少数群体看法的影响。仅对于在一般社会中具有高水平先前少数群体看法的 Facebook 用户，他们对共享新闻内容的敌意看法似乎鼓励了他们的政治参与。讨论了这些发现的影响。
