Institutions, mechanisms that govern behavior and social order, are important subjects of cultural evolution. Institutions can help stabilize cooperation, defined as behavior that benefits others, often at a personal cost.

We find that, in the presence of exclusion, central players contribute significantly less than others, and that this is tolerated by those others. Because of this tolerance, teams with centrality manage to maintain high levels of cooperation.
