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

About this video

Huberman interviews Dr. Kathryn Paige Harden, a psychologist and geneticist at the University of Texas at Austin, about how genes shape risk taking, morals and life outcomes. Dr. Harden studies how genes interact with life events during adolescence, when risk for mental illness emerges, to influence addiction, criminality, trauma susceptibility and long-term health. The conversation tackles sin, sociopathy, empathy and forgiveness directly, including her book Original Sin. Dr. Harden discusses why genetic explanations make moral judgment difficult: unlike a tumor or rabies, we cannot imagine the person someone would have been with a different genotype, so the self seems inseparable from the genes being judged. Huberman and Dr. Harden also discuss male-female differences, hormones and power structures.
