While these groups lack centralized institutions, they can and often do maintain large-scale cooperation. Here, we explore several mechanisms promoting cooperation in small-scale societies, including (a) the development of social norms that encourage prosocial behavior, (b) reciprocal exchange relationships, (c) reputation that facilitates high-cost cooperation, (d) relational wealth, and (e) risk buffering institutions. We illustrate these with ethnographic and psychological evidence from contemporary small-scale societies. We argue that these mechanisms for cooperation helped past and present small-scale communities adapt to diverse ecological and social niches. %K Foragers, Cooperation, Norms, Small-scale societies, Hunter-gatherers, Prosociality, Reputation, Reciprocity %J Current Opinion in Psychology %V 44 %& 44 %P 44 - 48 %I Elsevier %C Amsterdam %@ 2352-250X
