🚨Publication Alert!
My first first-author publication with @msaeltzer.bsky.social and @pluggedchris.bsky.social is out in @polbehavior.bsky.social, which began as my bachelor's thesis. We study how party polarization shapes affective polarization—with a particularly important role of the AfD. (1/7)🧵

Cover page of the article. "Affective States: Cultural and Affective Polarization in a Multilevel-Multiparty System" by Dylan Paltra, Marius Sältzer and Christian Stecker. "Affective Polarization—the growing mutual dislike among partisan groups—has been identified as a major concern in democracies. Although both economic and cultural ideological divides contribute to ideological polarization, their affective consequences can differ. This paper argues that cultural polarization becomes especially consequential when mobilized by far-right parties. Using data from 116 elections in Germany’s 16 states (1990-2023), we combine more than 550 state-level manifestos with more than 150,000 survey responses to examine how party polarization translates into voter affect. Our analyses show that both economic and cultural polarization increase affective divides, but cultural disagreements fuel hostility only in the presence of the Alternative for Germany (AfD). Acting as a cultural entrepreneur, the AfD amplifies the emotional impact of cultural divisions such as immigration, employing affective rhetoric and provoking strong rejection from other parties and voters. These findings highlight the catalytic role of far-right parties in transforming ideological competition into affective polarization."
