This thought-provoking Handbook examines a range of novel intersections between ethics and social psychology, extending the boundaries of the field beyond concerns of moral and positive psychology. It reflects on a range of social psychological approaches to moral issues, as well as on the ethical implications of social psychology research. Chapters cover fundamental aspects of morality and wellbeing, analyzing how these vary across cultures and time. They discuss key processes and phenomena at both an intra- and interpersonal level, from the psychology of regret and blame to moral disengagement and intergroup contact. Addressing questions surrounding climate change, animal product consumption, and the role of religion in human relationships, the Handbook emphasizes the importance of social psychological approaches for understanding ethical concepts. This discerning Handbook is an essential resource for students and scholars of psychology, sociology and philosophy, as well as the social sciences more broadly. It is also of great benefit to researchers seeking to understand new developments in the interdisciplinary study surrounding ethics and social psychology.
