#68 Meet the Neuroscientist Who has Scanned Over 5000 Psychopathic Brains!

Dr Kent Kiehl is a neuroscientist and clinical psychologist whose groundbreaking work has transformed how we understand psychopathy, morality, and the criminal mind.He’s the man who put an MRI scanner inside a truck and drove it into prisons across America — scanning over 5,000 inmates to uncover what makes a psychopath’s brain different. His discoveries reveal what happens when empathy, fear, and conscience fail to activate, and how these neural differences shape crime, punishment, and free will itself.Expect to learn how psychopathy develops in the brain, why psychopaths can understand right from wrong but don’t feel it, what brain areas govern impulse control and empathy, how neuroscience is being used to predict reoffending, and what treatments are showing promise — from cognitive behavioural therapy and mindfulness to emerging ideas like psychedelic-assisted therapy and neuromodulation.We also explore the ethics of brain-based sentencing, whether “evil” is a medical condition, how early interventions could prevent psychopathy before it forms, and what Kent’s research means for the future of law, morality, and the human condition.Timestamps: 00:00 Intro — Meet the Psychopath Whisperer04:35 What It’s Like to Sit Across from a Killer09:20 How Psychopathy Is Measured (The PCL-R Explained)14:15 Inside the Criminal Mind: Empathy, Fear & Free Will19:40 Building a Mobile MRI Lab to Study 5,000 Inmates25:30 What Brain Scans Reveal About Conscience and Control31:25 Predicting Crime: The Neuroscience of Recidivism37:50 Brain Circuits of Morality and the “Oh Damn” Signal44:10 Can Psychopaths Change?
