Topics and Scope

We invite submissions of research on topics broadly related to social dilemmas. Research providing insights into how people approach and resolve conflicts between self-interest and collective interests is of particular relevance. 

As social dilemmas span multiple academic disciplines, submissions from a wide range of scientific fields, including but not limited to psychology, economics, anthropology, biology, environmental sciences, neuroscience, sociology, political science, applied mathematics, and computer science are welcome. 

We welcome empirical research on social dilemmas, including topics such as cooperation, social norms, emotions, trust, and conflict. We also invite theoretical contributions on formal games related to social dilemmas, such as public goods games, coordination games, prisoner's dilemmas, trust games, dictator games, and other theoretical innovations. 

Lastly, we encourage empirical contributions that inform us about the practical applications of research on social dilemmas in societal issues, such as donations, prosocial attitudes, and climate change.
