Summary

The growth of research on emotion in international relations (IR) has produced a significant body of literature. This body of literature has raised a number of interesting questions, debates, and theoretical positions regarding the agentic properties of international actors and how they are embedded in international structures. Emotions have long been viewed in IR as self-evident and irrational by-products of cognitive processes and have, until recently, remained largely implicit and undertheorized. The first wave of research lamented the discipline’s neglect and marginalization of emotions in mainstream IR theories and concepts. The second wave has turned to specific ways to integrate the consideration of emotion into existing research within specific issue areas, from diplomacy, security, war, and ethnic conflict to transnational actors, institutions, governance, and conflict management. The literature on this topic is so extensive that many even speak of an “emotional turn.” Its intellectual roots stem from various disciplines, such as psychology, neuroscience, sociology, history, and cultural studies, and this diversity is reflected in ongoing challenges of how to study emotions and their political effects in IR. These challenges relate to a number of ontological and epistemological questions, including how to conceptualize emotions, how to capture emotions methodologically, and how to move from the individual to the collective level of analysis. Whatever divergent claims are made by these scholars, there is by now a firm consensus in the discipline that emotions matter for international and global politics.
