Key research themes
1. How do punishment mechanisms influence the evolution and maintenance of human cooperation?
This research theme focuses on the functional roles, evolution, and comparative effectiveness of punishment (including altruistic, peer, and collective punishment) as mechanisms to sustain and promote cooperation in social dilemmas. It investigates how different punishment strategies impact cooperation dynamics, the emergence of cooperation in populations, and the limitations posed by factors like second-order free riding and antisocial punishment.
2. What are the cognitive and neural mechanisms underlying third-party punishment and cooperation enforcement?
This theme explores the psychological motivations and neurocomputational substrates of third-party punishment—where uninvolved observers punish norm violators to uphold social norms—and how factors like social distance and intentionality modulate these processes. It integrates behavioral economics, neuroimaging, and experimental game theory to uncover how individuals perceive fairness, reciprocity, and social ties in sanctioning decisions and the distinction between punishment and compensation.
3. How do incentives, norms, transparency, and institutional structures impact cooperation and punishment preferences in social dilemmas?
This research theme addresses the broader social, institutional, and psychological factors that shape cooperation and punishment choices, including how costs, norms, transparency, and social context affect the demand for punishment institutions or alternatives, the evolution of cooperation, and the moral perceptions related to exploitation and altruism. It incorporates both empirical lab experiments and conceptual analyses.
