The C3 Lab studies culture, conflict, and cooperation in an increasingly globalized and interconnected world. We use a combination of methods, from traditional lab experiments to archival research and longitudinal modeling. We conduct research across countries, cultures, and religions. Below are some ongoing topics of research in the lab.

How do people define their groups?

People construct boundaries around their social groups, reflecting who they view as “true” members of the ingroup. Do these boundaries shift in response to different contexts, like ecological threat or inequality? We study the dynamic nature of the boundaries people construct around their groups, when and why these boundaries might expand and contract, and the consequences of changes to these group boundaries.

How do different groups influence each other?

How does cultural information spread between different groups? Cultures have rich profiles of norms, beliefs, and behaviors. As groups come into contact in a globalizing world, what kinds of information gets transmitted between groups, and what doesn’t? How do perceptions and attitudes toward other groups shape this transmission?

How does intergroup cultural transmission shape conflict and cooperation?

When cultural norms and practices are transmitted between different groups, what are the implications for intergroup and intragroup dynamics? We study when and why this transmission may help or harm attitudes both between and within groups.
