When News Matters: Media Effects on Public Support for European Union Enlargement in 21 Countries

First, this study tests for media effects on support for EU enlargement in a natural setting, while including actual media content in the analysis. Second, the moderation by anti‐immigrant attitudes of media effects is tested, as it is argued that perceptions of ‘others’ influences how new information on enlargement is received. The study draws on a two‐wave panel survey and a media content analysis in 21 countries. The results suggest there is a media effect, although not from individual exposure but from the information environment. In addition, individuals with stronger anti‐immigrant attitudes are more strongly affected by a negative information environment.
