In this episode of the Enriched Mindset Podcast, Dr. Lee and Gracie Ward sit down with Professor Pat Barclay, an evolutionary psychologist at the University of Guelph, to unpack the real forces shaping human behavior — from why we help others to why we sometimes… really don’t. Drawing from decades of research on cooperation, reputation, and competitive altruism, Pat breaks down the hidden motives behind everyday actions. A major highlight of the episode explores dating psychology — including the classic “nice guys vs. bad boys” debate. Pat shares research showing how altruism signals long‑term partner value, why competence matters as much as warmth, and how people balance attraction, trust, and long‑term cooperation when choosing partners.
