#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.
