Most research on media and politics focuses on explicitly political content, such as news. Yet this makes up only 3% of what people encounter online. The large majority is everyday content: entertainment, lifestyle sites, and social media influencers. HIDDENPOL asks whether this widely consumed content also shapes citizens' political values, beliefs, and orientations, and what that means for today's democratic challenges.
The project develops new theory on how and when everyday media matter politically. It tests this theory through large-scale content analysis, audience research, and survey and field experiments in the Netherlands, Spain, and the United States.
The results will inform both media-effects research and current policy responses to challenges such as misinformation, polarization, and declining trust.
