Reassessing conceptualization,data and causality: A critique of Boomgaarden and Vliegenthart's study on the relationship between media and the rise of anti-immigrant parties

This article critically assesses the study of Boomgaarden and Vliegenthart (2007) on the relationship between media content and anti-immigrant party support. With regard to conceptualization, it is argued that their dependent variable is flawed, because it groups two parties together that do not belong to the same party family. Some data-related issues, such as measurement equivalence, are also discussed. Finally, it is argued that the causality might be easily reversed. Because anti-immigrant parties are able to exploit issues which are neglected by mainstream parties, it is possible that the media will give more attention to these issues. This study concludes that a causal relationship between news content and anti-immigrant party support is nonexistent in the Dutch case.
