Cults provides an in-depth exploration of the psychological, social, and cultural dynamics behind cult movements. Drawing on his expertise as a psychiatrist and years of research, Galanter examines why individuals are drawn to cults and how these groups foster intense loyalty, even at great personal cost. He investigates their appeal, the role of charismatic leadership, and the psychological mechanisms of group influence, while also analyzing their parallels with mainstream religions and therapeutic communities. The book sheds light on phenomena like mass conversions and destructive obedience, offering insights into how belief systems shape human behavior and the social challenges they pose.
