David C. Geary is Curators' Distinguished Professor and Thomas Jefferson Fellow in the Department of Psychological Sciences at the University of Missouri. In this episode, he talks to Greg Ashman about his influential theory of evolutionary educational psychology that categorises knowledge as biologically primary or biologically secondary. Along the way, Dave and Greg discuss knowledge transmission in traditional societies, some common criticisms of the biologically primary/secondary distinction and both the artificality and importance of school.
