Some people live in social media "news deserts," while others are embedded in online networks that are rich in news content. These news deserts represent a new form of digital inequality—distinct from problems of access, resources, or civic skills—that could foreclose one of the ways social media are believed to contribute to informing citizens and engaging them in democratic processes: providing opportunities for incidental news exposure. This study investigates incidental exposure on social media platforms, drawing on an online survey administered just before the 2018 US Midterm Elections ( N = 1493). The study finds that even after controlling for key individual-level factors, characteristics of social media discussion networks play a role in explaining variation in incidental exposure. The results are discussed in light of prevailing theory about incidental exposure, public engagement, and digital inequalities.

The aim of this study is to investigate the causal direction of the relationship between incidental news exposure via social media and political participation. Unlike prior studies, which have relied on cross-sectional data to examine this link, we used two panel data sets to better identify causal relationships. Specifically, we evaluate two unidirectional models (i.e. mobilization and reinforcement) and a reciprocal causal model using both cross-lagged and autoregressive path models. The findings reveal a more complex relationship than most previous studies have suggested. The relationship between incidental news exposure via social media and political participation appears to be reciprocal, with incidental news exposure and political participation indirectly influencing each other through social media use for political purposes. Furthermore, while the relationship between incidental news exposure and political participation is reciprocal, the participation-to-incidental news exposure path exerted a stronger effect than the reverse path in both studies.
