When the Claws Come Out: What Animals Teach Us About Conflict Resolution
Thursday, Feb. 12, 6:00 pm – Whitney Academic Center #153. Free.
With Rachel Kristiansen, Psychology Faculty
- Discover how animals resolve conflict and maintain social harmony
- Explore the science behind cooperation, empathy, and reconcilliation
- Gain fresh insights into what human relationships can learn from the animal world.
Conflict is a universal feature of social life, but how it’s managed can mean the difference between survival and extinction. From elephants reconciling after fights to vampire bats sharing meals with former rivals, the animal kingdom offers remarkable strategies for restoring peace and maintaining group harmony. This lecture explores the psychology and biology of conflict resolution across species, highlighting parallels with human behavior and insights into the evolutionary roots of cooperation, empathy, and social repair. Drawing from ethology, neuroscience, and behavioral psychology, we’ll examine how animals negotiate disputes, employ reconciliation rituals, and balance aggression with affiliation. Ultimately, these behaviors reveal what it means to coexist in complex social systems, and what humans might learn from our nonhuman counterparts about the art of making peace.
