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.
