This book introduces a comprehensive and integrative collection of psychological intergroup interventions. These evidence-based interventions are scientifically established and tested in several real-world contexts of intergroup animosities and tensions, from prejudice and inequality reduction to peace promotion. Intergroup hostility, violence, and discrimination have become more and more prevalent in recent decades. To address this challenge, recently, social scientists have shown an increasing shift from a descriptive to a more interventionist science, developing evidence-based interventions to improve intergroup relations. For the first time, this book includes research on intergroup interventions and their applications to the field, from a global collection of leading voices in the discipline. It also includes a conceptualization of intergroup interventions, a typology of different types of interventions, as well as a guideline for effective development of intergroup interventions. Each chapter focuses on one psychological intergroup intervention, further reviewing a sample of relevant platforms such as education, entertainment, and VR, upon which psychological intergroup interventions can be implemented.With each chapter featuring both intervention research and practical advice for practitioners, this is the ideal companion for researchers and professionals in social psychology, sociology, politics, peace studies and conflict resolution. It will also be of interest to practitioners looking for practical advice to create an impact in the real-world.
