Abstract
This research examines the development of echo chambers within conventional media outlets through a study of U.S. cable news viewership. Based on data from the 2020 Cooperative Election Study (CES), the research studies how partisan identity influences viewership of partisan networks and how media choices affect public opinions regarding controversial policy issues. The study uses a Conditional Mixed Process (CMP) model to analyze the relationship between partisan identity and media group affiliation while logistic regressions evaluate the relationship between media group membership and policy attitudes. The result demonstrates that people with intense partisan loyalties tend to choose media outlets that match their political beliefs which proves the existence of cable news echo chambers. Additionally, people who watch news within echo chambers demonstrate more intense and consistent ideological positions regarding policy matters than people who watch neutral or mixed media content. People who watch news from both conservative and liberal perspectives maintain centrist positions. These findings support the hypothesis that cable news echo chambers both reflect and reinforce ideological polarization in the American electorate.
