#22: Group Mind pt. 3: Oxytocin Atrocities

We use religious cults as an example of extreme group psychology to make generalizations about the group dynamics that determine sociopolitical possibility. We investigate the relationship between ingroup cohesion and outgroup animosity, the oxytocin-laden war rituals of chimpanzees, the unique human developmental biology associated with social cognition, and the general neurobiology of the repetitive group dynamics we encounter.
