Episode Details

Chris Williamson sits down with evolutionary psychologist Steve Stewart-Williams to unpack why sex differences are scientifically real, often modest, and still so politically charged. This summary condenses the full Modern Wisdom episode into the key ideas: how biology, evolution, hormones, childhood development, and culture shape human behavior; why men and women differ on average in aggression, sociosexuality, parenting, health, and interests; and why those averages say nothing about any individual. Stewart-Williams explains the evidence for innate differences, the limits of statistical overreach, and why telling the truth about sex differences matters for psychology, medicine, policy, and everyday life. Learn how the “gender equality paradox,” reproductive strategy, and cross-sex attraction help explain the data without reducing people to stereotypes. Listen now to get the key ideas in minutes.
