By drawing on theories and methods from psychology, economics and related disciplines, we aim to better understand how people make judgments and decisions in social interactions. 


We aim to contribute to the solution of societal problems and challenges. This includes basic research on, for instance, social interactions (particurly human cooperation and prosociality), but also applied research in specific contexts. We apply a broad range of methods, including (online, lab and field) experiments, survey studies and computational modeling. Some of our main research areas are the following: 

  • Intergroup conflict and violence
  • Health decision making, such as vaccine uptake and antibiotic use
  • Environmental and climate protection
  • Human-computer interaction and human-human interaction in digital environments
  • Reactions to and interactions with institutions and policies, such as in the context of tax regulations or health policies
