Cooperation is a markedly human mix of innate and learned behaviour, and a key to tackling some of our greatest concerns. Paradoxically, studies of social dynamics often focus on hierarchies, state formation and political structures ruled by coercive power, with comparatively little regard to the mechanisms whereby humans voluntarily collaborate. Encouragingly, new research on collective action is reconciling classic anthropology with game theory and empirical studies of group resource management, thus heralding a fundamental transformation.
