Why do we crave revenge? And why can’t we stop? In this episode, James Kimmel explains the neuroscience behind one of our most destructive urges. Drawing from his new book, The Science of Revenge: Understanding the World’s Deadliest Addiction, Kimmel reveals how revenge activates the same brain circuits as drugs like cocaine—and why even imagining payback can feel euphoric.

If you’ve ever fantasized about revenge (and who hasn’t?), whether in politics or personal relationships, this episode offers a chilling yet hopeful look at the science of moral outrage and redemption.

James Kimmel, Jr., JD, is a lecturer in psychiatry at the Yale School of Medicine, a lawyer, and the founder and co-director of the Yale Collaborative for Motive Control Studies. A breakthrough scholar and expert on revenge, he first identified compulsive revenge seeking as an addiction and developed the behavioral addiction model of revenge as a public health approach for preventing and treating violence. His new book is The Science of Revenge: Understanding the World’s Deadliest Addiction—and How to Overcome It.
