Colin Wayne Leach is a social psychologist who also wears a bunch of other social science hats. He approaches the social world by appreciating its nature as a system of interconnected parts. He's made strides in a lot of research areas, including emotion, prejudice, and morality.

In our conversation, we focus on his work on protest as a vehicle for social change. He shares how he thinks about protest and the system it's embedded in, and walks us through what protest is and how we can understand it better.

If you're interested to learn more, you can read a great recent summary of Colin's perspective in Group Processes & Intergroup Relations (Leach et al., 2024)
