Disagreement persists as to whether social networking sites (SNSs) are used more frequently to facilitate cross-cutting or like-minded discussions. We examine the relationship between the use of SNSs and involvement in discussions with politically similar and dissimilar others among a sample of US Democrats and Republicans. Affective polarization is negatively related to involvement in cross-cutting discussions, suggesting that individuals extend their dislike of the opposing political party to out-party members within their online social networks. Moreover, political discussion with one’s friends on SNSs plays a mediating role in involvement in both cross-cutting and like-minded discussions. Finally, party identification moderates the relationship between SNS use and involvement in cross-cutting discussions, indicating that Republicans participate more frequently than Democrats in cross-cutting exchanges on SNSs. In the light of these findings, we discuss the contribution of SNSs to the ideals of deliberative democracy.

Drawing on a panel survey and a laboratory experiment, this study investigates incidental exposure to counter-attitudinal political information on Facebook. The frequency of Facebook use is found positively associated with incidental exposure to counter-attitudinal political information, suggesting the important role of Facebook in exposing users to political disagreement. In addition, the findings of the experiment indicate that individuals coming across counter-attitudinal Facebook posts are able to recognize the information of these posts. This study suggests that incidental exposure is an important mechanism through which social media users encounter and learn about counter-attitudinal political information. Implications are discussed in terms of the influence of social media use on democracy.

While COVID-19 is becoming one of the most severe public health crises in the twenty-first century, media coverage about this pandemic is getting more important than ever to make people informed. Drawing on data scraped from Twitter, this study aims to analyze and compare the news updates of two main Spanish newspapers El País and El Mundo during the pandemic. Throughout an automatic process of topic modeling and network analysis methods, this study identifies eight news frames for each newspaper’s Twitter account. Furthermore, the whole pandemic development process is split into three periods—the pre-crisis period, the lockdown period and the recovery period. The networks of the computed frames are visualized by these three segments. This paper contributes to the understanding of how Spanish news media cover public health crises on social media platforms.

Abstract. This experiment (N = 193) explores the effects of cross-cutting exposure via social media on two types of political participation. The results reveal that exposure to cross-cutting social media news can motivate cheap participation better than costly participation. Moreover, the mobilizing effects of cross-cutting exposure are mediated by anger and anxiety, as suggested by affective intelligence theory and appraisal theories of emotion. The mediating effects of anxiety are also moderated by online incivility. Implications are discussed in terms of the role of social media use and cross-cutting exposure in participatory democracies.

Drawing on the 2012 American National Election Studies (ANES) panel data, this study explores the influence of the consumption of partisan information sources on affective polarization and investigates the mechanism underlying this relationship. The results show that exposure to pro-party television sources strengthens affective polarization among partisans. The polarizing effects of pro-party sources are mediated by the discrete negative emotions (i.e., anger and fear) toward presidential candidates. The study discusses the impact of selective exposure on deliberative and participatory democracies.
