Causes and Consequences of Selective Exposure Among Political Blog Readers: The Role of Hostile Media Perception in Motivated Media Use and Expressive Participation

Concerns about selective exposure to partisan information have become a mainstay for scholars of political communication in the changing media environment. This study draws on a survey of a unique population—readers of political blogs—to explore the relationship between perceptions of mainstream media bias (as hostile media perception) and selective exposure to media sources that provide like-minded information as well as social support. We find that hostile media perception is an important motivator for partisan selective exposure among this audience, and also that such perceptions can lead indirectly to expressive political participation by encouraging visits to politically homogeneous online spaces.
