The impact of emotions on polarization. Anger polarizes attitudes towards vaccine mandates and increases affective polarization

When does anger lead to greater polarization? As societal polarization and political polarization increase so does academic interest in its antecedents. One important cause of polarization appears to be anger. However, existing research linking anger and political polarization has focused primarily on the context of partisanship and did not distinguish between different types of anger nor different forms of polarization. To address this gap in the literature, we analyze how generalized versus issue-specific anger amplify issue-based and affective polarization in the highly charged context of the COVID-19 pandemic. We test these relationships through a survey experiment embedded in a national German sample (n = 2857) and show that anger is linked to polarization. However, we also show that different forms of anger influence different aspects of polarization. Issue polarization is driven primarily by generalized anger, while corona-specific anger increases affective polarization. Together, these results underline the importance of understanding the emotional nuances of polarization. More generally, the results illustrate the problems policy makers face when navigating heavily contested and emotionally charged topics. While increased anger may be helpful for mobilizing support among already supportive citizens, it does little to convince skeptical citizens and carries the cost of increasing societal polarization
