How Genes Shape Your Risk Taking & Morals | Dr. Kathryn Paige Harden | Huberman Lab

This episode explores the complex interplay of genes, environment, and individual choices, particularly during adolescence, in shaping human behavior and mental health. Psychologist and geneticist Dr. Kathryn Paige Harden discusses how genetic predispositions interact with life events to influence addiction, criminality, and trauma susceptibility. She highlights research indicating that genes affecting impulsivity and addiction are often expressed during early neurodevelopment, impacting the brain's balance of excitation and inhibition. The conversation touches on the ethical considerations of genetic testing, the societal implications of punishment versus forgiveness, and the evolutionary roots of moral outrage. Dr. Harden advocates for a forward-looking approach to justice, emphasizing rehabilitation and societal safety over retributive punishment.
