Converging paths: bounded rationality, practice theory and the study of change in historical international relations

Abstract Bounded rationality and practice theory have both become popular theories of action for major strands of work in constructivist and rationalist International Relations (IR). Based on this observation, I make two arguments. The first is that although they underpin what are generally seen as opposed theoretical camps in IR, bounded rationality and practice theory share two fundamental assumptions. They both accept that how agents process information and make decisions depends on where they are situated in social space, and where they stand in historical time. In turn, these shared assumptions imply that they agree on the existence of a common type of change: change in terms of how groups of people process information and make decisions over time. My second argument is that by studying this type of change, it is possible to shed new light on major transformations of international relations, and that one way of engaging in this type of research is to study international practitioners' education over substantial time periods. With these arguments, this article makes a methodological contribution to the study of change in historical international relations and charts a practical course for pluralist dialogue in IR.
