How much are you a product of your genes, and how much are you a product of your experiences? Or are you a free agent, acting in spite of your biology and environment?Kathryn Paige Harden is a world-renowned psychology professor who specialises in how genes affect our behaviour. She was nearly cancelled during the era of Peak Woke for her book 'The Genetic Lottery: Why DNA Matters for Social Equality'. Her research, while egalitarian in intent, was demonised as paving the way for eugenics.Now, Professor Harden reveals even more fascinating links between genes and addiction, appetite, sex and violence in her amazing new book ‘Original Sin: On the Genetics of Vice, the Problem of Blame, and the Future of Forgiveness.’She joins Josh to discuss nature, nurture, free will, dysfunction, genetic predispositions, and what taking acid taught her about being human.
