Just a Big Misunderstanding? Bias and Bayesian Affective Polarization

Abstract: I present a model of affective polarization—growth in hostility over time between two parties—via quasi‐Bayesian inference. In the model, two agents repeatedly choose actions. Each choice is based on a balance of concerns for private interests and the social good. More weight is put on private interests when an agent's character is intrinsically more self‐serving and when the other agent is believed to be more self‐serving.

“…As research in this area has flourished across multiple social science disciplines, many distinct phenomena across differing levels of analysis have been labelled 'polarization'. For example, polarization, specifically affective polarization, is often operationalized as the extremity of an individual's prejudice towards a political outgroup [3,9,10]. Other times, polarization is defined as individuals' ideological or issueposition extremity [11,12], or as the strength of their partisan ingroup identification [13].…”

For example, polarization, specifically affective polarization, is often operationalized as the extremity of an individual's prejudice toward a political outgroup (e.g., Iyengar et al, 2019;Simas et al, 2020;Stone, 2020). Other times, polarization is defined as individuals' ideological or issue-position extremity (e.g., Rollwage et al, 2018;Stanley et al, 2019), or as the strength of their partisan ingroup identification (e.g., Mason, 2018).…”
