Causes and consequences of coalitional cognition

What is a group? How do we know to which groups we belong? How do we assign others to groups? A great deal of theorizing across the social sciences has conceptualized ‘groups’ as synonymous with ‘categories,’ however there are a number of limitations to this approach: particularly for making predictions about novel intergroup contexts or about how intergroup dynamics will change over time. Here I join a growing chorus of researchers striving to systematize the conditions under which a generalized coalitional psychology gets activated—the recognition of another’s capacity for and likelihood of coordination not only with oneself but with others. First I review some recent developments in the cognitive processes that give rise to the inference of coalitions and group-biased preferences (even in the absence of category labels). Then I review downstream consequences of inferences about capacity and likelihood of coordination for valuation, emotions, attribution, and inter-coalitional harm. Finally I review examples of how we can use these psychological levers to attenuate intergroup hostility.
