Stumbling upon the other side: Incidental learning of counter

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
