The Ecological Rationality of Situations

The study of situations involves asking how people behave in particular environmental settings, often in terms of their individual personality differences. The ecological rationality research program explains people’s behavior in terms of the specific decision-making tools they select and use from their mind’s adaptive toolbox when faced with specific types of environment structure. These two approaches can be integrated to provide a more precise mapping from features of situation structure to decision heuristics used and behavioral outcomes. This chapter presents three examples illustrating research on ecological rationality and its foundations, along with initial directions for incorporating it into an integrated situation theory.
