Partisan news and political participation: exploring mediated relationships

This study examines mediators of the relationship between news consumption and political participation in the contemporary news environment. We test the differential effects exerted by pro- and counter-attitudinal news compared with balanced news on intended participation. Our primary objective is to model three paths that may link news exposure and participation: cognitive (i.e., perceived issue understanding), affective (i.e., emotions evoked by a news story), and attitudinal (i.e., attitude strength). We compare these paths across four issues, testing which is strongest. Relying on a large survey-based experiment on a representative sample of the American population (N = 2,300), we find that pro-attitudinal exposure increases intended participation relative to balanced news exposure, while the effects of counter-attitudinal news do not differ from those exerted by balanced news. Issue understanding, anger, positive emotions, and attitude strength all mediate the relationship between pro-attitudinal exposure and intended participation, with the route via attitude strength being strongest. These effects do not depend on whether exposure is self-selected or experimentally assigned.
