This document summarizes a study that examined how opinionated news affects citizens' political attitudes. The study tested two hypotheses: 1) that presumed influence of opinionated news shapes perceived opinion climate and attitudes, and 2) that perceptions of bias mediate the relationship between political preferences and attitudes. Results supported both hypotheses, finding opinionated news indirectly shaped attitudes by influencing perceived opinion climate and triggering perceptions of bias. The study suggests opinionated news can indirectly influence attitudes through both cognitive and affective mechanisms.
