This volume offers a state-of-the-art study of the diverse methodological approaches and issues in the study of emotions in international relations research. While interest in emotion and affect in IR has grown in recent years, there remains an absence of sustained engagement with questions of methodology and method. Although much of the field holds the ‘emotions turn’ as laudable, it is commonly seen as facing serious, even prohibitive, methodological challenges. Using a common framework for making discussions of methodology and emotion mutually intelligible, this work seeks to address this lacuna and will be of interest to students and scholars of international relations, research methods and IR theory.
