Social media use seems to hinder rather than enhance an individual’s learning about politics, because it fosters the perception that one no longer needs to actively seek news in order to stay informed (i.e., news-finds-me perception)

ABSTRACT: This study examines the causal effects of social media use on political knowledge as well as the underlying mechanisms through which such an effect occurs. The findings suggest that social media use hinders rather than enhances an individual’s learning about politics, because social media use fosters the perception that one no longer needs to actively seek news in order to stay informed (i.e., news-finds-me perception), and this in turn may have an adverse effect on an individual’s learning about politics. However, those who use traditional forms of media to a substantial degree to complement their news consumption via social media are less negatively affected than those who do not.
