Dr. Greg Walton — Stanford psychologist, co-director of the Dweck Walton Lab, and author of Ordinary Magic: The Science of How We Can Achieve Big Changes with Small Acts — unpacks how wise interventions create extraordinary change. Sparked by Claude Steele's stereotype threat research as a high school student, Greg has spent his career proving small acts matter profoundly: simple postcards sent to psychiatric patients reduced suicides, belonging interventions help students spiral up instead of down, police transparency statements ("I'm trying to get to know people in my neighborhood") transform civilian encounters. Greg introduces "TiffBits" (Tiny Fact, Big Theory) — moments like his brother's untucked shirt ending a relationship or an In-N-Out burger line triggering belonging worries — small events carrying big meaning. The framework: wise interventions are done WITH people (offering, not persuading), ask sincere questions and listen ("What's it like for you?"), develop your "psychological ear" to understand others' experiences, create space that anticipates goodness and invites people to tell their stories, and remember discomfort might mean you care (Kiara Sanchez's research on cross-racial conversations). Small acts, extraordinary outcomes — ordinary magic accessible to everyone.
