A new article entitled "Strikingly similar: Comparing visual political communication of populist and non-populist parties across 28 countries" is now available in the European Journal of Communication. It was authored by Xénia Farkas, Daniel Jackson, Paweł Baranowski, Márton Bene, Uta Russmann, and Anastasia Veneti.
The authors' goal has been to determine the distinct characteristics of the populist visual communication style and its possible differences in relation to the non-populist parties. Applying quantitative content analysis to images posted on Facebook by political parties by the 28 member states during the 2019 European Parliament campaign, the authors conclude that populist communication does not explicitly manifest through images.
