Road rage demonstration and triggers

What if the most dangerous addiction in the world isn't drugs, alcohol, or gambling—but revenge? In this eye-opening conversation, I sit down with Dr. James Kimmel Jr., Yale School of Medicine researcher, attorney, and author of The Science of Revenge, to unpack what actually happens in our brains when we feel wronged, humiliated, or disrespected.

Dr. Kimmel breaks down the neuroscience behind revenge, why it lights up the brain the same way cocaine does, and how seeking retaliation gives us a temporary dopamine hit that ultimately leaves us worse off. We talk about anger, forgiveness, sibling rivalry, marriage conflict, parenting mistakes, and why forgiveness isn't weakness—it's one of the most powerful tools we have to reclaim peace, leadership, and self-control as men and fathers.

Five Key Takeaways

1. Revenge activates the same brain circuits as drugs and gambling, making it addictive and compulsive for some people.
2. Emotional wounds register as real physical pain in the brain, triggering a desire to self-medicate through retaliation.
3. Revenge provides temporary relief but increases anger, anxiety, and depression after the dopamine fades.
4. Parents can unintentionally cross the line from discipline into revenge, especially when ego and shame are triggered.
5. Forgiveness is not weakness—it's neuroscience. It's one of the most powerful ways to reclaim control, peace, and leadership.
