Explore the 'group mind' phenomenon and uncover its influences on religious and political experiences. This book investigates the idea that human groups, under certain conditions, can develop distinct personalities and possess 'minds' characterized by quasi-rational decision-making processes, emotions, intentional states, and actions in the world. Utilizing expert research, Patrick McNamara applies the explosion of findings in collective cognition to topics in evolutionary psychology, social science, and religion to demonstrate the associations between group minds and supernatural agents. The chapters examine the relationship between religious group minds and individual psychology from multiple perspectives, including identity dynamics, inter-group relations, group theory of mind, and the neuroscience of in-group monitoring. The book also addresses how religious groups evolve, maintain cohesion, and shape individual brains, offering a novel framework for understanding how collective minds emerge and operate. It is an essential resource for those interested in the psychology of religion, philosophy, and religious studies.
