International Relations Theory - Evolutionary Perspectives

Evolutionary Perspectives

Evolutionary perspectives, such as from evolutionary psychology, have been argued to help explain many features of international relations. Humans in the ancestral environment did not live in states and likely rarely had interactions with groups outside of a very local area. However, a variety of evolved psychological mechanisms, in particular those for dealing with intergroup interactions, are argued to influence current international relations. These include evolved mechanisms for social exchange, cheating and detecting cheating, status conflicts, leadership, ingroup and outgroup distinction and biases, coalitions, and violence. Evolutionary concepts such as inclusive fitness may help explain seeming limitations of a concept such as egoism which is of fundamental importance to realist and rational choice international relations theories.
