 Finally, we stress that different contextual factors (such as the framing and characteristics of the strategic problem, the role one is assigned, the social category with which one identifies, as well as historical and chance events) often come to be associated with different notions of “appropriate behavior”. Accounting for endogenous expectations is therefore key to a full understanding of norm-driven behavior. More research—both theoretical and experimental—is needed to further illuminate the impact of expectations on strategic decisions.
