Affective polarization in Latin America: A research note

Abstract Affective polarization (AP), a concept that summarizes intense partisans’ animosity towards opposing parties and positive feelings towards their own, has recently received increasing attention. Despite a growing interest in Latin American polarization, there are very few empirical studies on the range and depth of dislike and distrust towards political adversaries in the region, and how this impacts the quality of democracies. This research note uses survey data collected after ten election cycles in six countries to estimate the scope and depth of AP in the region. We measure the extent of polarization in Latin America compared to other Western nations, assess its evolution, and makes some inroads to explain who drives AP. On aggregate, Latin America does not show large AP scores, yet there are clear signs of an upward trend. More than a widespread social phenomenon, the evidence suggests that AP is driven by large intense minorities.
