Is Morality the Cause of Ideological Disagreement?

This week we ask what drives ideological disagreement in politics? How far do people on left and right disagree with each other because they have fundamentally different moral intuitions or for other reasons? Polarisation is a defining feature of contemporary politics, raising concerns among many observers. People on the left and right—liberals and conservatives—often seem to inhabit entirely different worlds, holding fundamentally distinct perspectives on reality and morality. But what underpins these divisions? Are they rooted in deep-seated moral intuitions that we are born with or develop in childhood? Or do they stem from our present circumstances and the media landscape that shapes our understanding of the world? In this episode, we explore ground-breaking research by two scholars from the UCL Department of Political Science—Dr Jack Blumenau and Prof Ben Lauderdale. Their work offers fresh insights into the nature of political disagreement, challenging conventional wisdom about its origins. Jack join us to discuss these findings.
