The new generationalism: Generational antagonism and partisan polarization

Abstract Despite the prevalence of generational labels like Boomers, Gen X, Millennials, and Gen Z in popular discourse, most studies of generationalism have been restricted to content analyses of generational rhetoric. This study investigates the prevalence of negative generationalism, or negative affective sentiment towards perceived generational out‐groups within the US public and considers how it may be linked with partisan political identities. Using a nationally representative survey of 1232 Americans, this research examines the association between generational self‐identity and partisan identity using feeling thermometer scores for four generational groups (Boomers, Gen Xers, Millennials, and Gen Z) and the two major political parties (Democrats and Republicans). I also report the findings of an experimental manipulation testing the extent to which generational priming exacerbates affective partisan polarization. The results reveal strong evidence of positive affect towards one's generational in‐group, but a less consistent pattern of negative generationalism. Neither the correlational nor the experimental outcomes support a strong and consistent link between generationalism and partisanship, though Republicans feel significantly warmer towards Baby Boomers and colder towards Gen Z than independents. Despite the largely null findings concerning partisanship, this study reveals that these generational labels do appear to bear some degree of social meaning as social identities for people, pointing to new directions for future sociological research on generationalism.
