Ideological Polarization and Social Psychology
Ideology is a recurrent feature of human societies. Ideologies provide people with frameworks to evaluate the relative legitimacy of different approaches to social order. Such ideologies often involve an opposition between right-leaning ideologies, which tend to justify and maintain the traditional order, and left-leaning ideologies, which advocate for systemic reforms to reduce hierarchies. Social psychological investigations of ideology explore the root motivations and moral foundations of people’s attraction to left versus right ideologies. In particular, such work focuses on understanding the motivational dynamics of ideologies that justify the status quo, promote authoritarian control, and rationalize social dominance hierarchies. Social psychological research also investigates information-processing biases that increase the polarization between left and right. These insights can be applied to bridge divides within ideologically polarized communities.
