Does news help us become knowledgeable or think we are knowledgeable? Examining a linkage of traditional and social media use with political knowledge

This study examines traditional and social media news use in relation to political knowledge from the perspective of the Dunning-Kruger effect. Data from a two-wave panel survey show that social media use for news is positively related to knowledge miscalibration, or a mismatch between subjective and factual political knowledge. That is, respondents who use social media for news often tend to overestimate their levels of knowledge. In contrast, traditional news use is negatively associated with knowledge miscalibration. These results seem attributable to the role of social media news use in fostering subjective political knowledge and traditional news use in facilitating factual learning. Implications are discussed for the role of news consumption in the political process.
