The logic of habit in International Relations

IR theory is dominated by the logics of consequentialism and appropriateness. But Max Weber offered four logics of choice, not just two. Beyond the instrumental rationality of Zweckrationalität and the normative rationality of Wertrationalität are affect and habit. Drawing on Weber, James, Dewey, and Bourdieu, and habit’s microfoundations in neurocognitive psychology, I explore the logic of habit and its consequences for several fundamental puzzles in IR theory. The logic of habit necessarily precludes rationality, agency, and uncertainty, and so offers a different interpretation of cooperation, security dilemmas, enduring rivalries, and security communities in international politics. The logic of habit also fills a gap in mainstream constructivism’s theorization of intersubjective structures, returning the taken-for-granted lifeworld to the center of attention.
