My research expertise is on human cooperation, the reasons for its existence, and the psychological mechanisms that underlie cooperative action. In particular, I investigate the importance of reputation within human social relationships, including competition over a reputation for generosity (i.e., competitive altruism). As an evolutionary psychologist, my research draws from evolutionary biology, animal behaviour, mathematical game theory, experimental and behavioural economics, anthropology, social psychology, and cognitive psychology. By using this approach, my research tries to understand when and why people help others, what design features in the brain promote generosity, what selective pressures could have resulted in the brain being designed this way, and how we can harness this knowledge to promote cooperation in domains as broad as workplaces, environmentalism, and charities.
My research typically uses games from behavioural economics (such as the well-known Prisoner’s Dilemma and public goods games) where participants can make decisions with money to benefit themselves, others, or both. We then run these experiments in our lab or online (e.g., MTurk). I often complement these experiments with mathematical models (evolutionary game theory) to advance our theoretical understanding of cooperation.
In addition to my research on cooperation and prosocial behaviour, I also have a secondary line of research on risk-taking.
