Bill von Hippel, a psychology professor and author, dives into the evolution of human behavior and social dynamics. He explains how the theory of mind gives humans a unique advantage over animals and discusses why hunter-gatherer societies were more egalitarian. The conversation explores our innate ability to perceive deception and how this skill shaped our survival. Von Hippel humorously addresses why we often dislike our photos and the psychological implications of self-perception in social interactions. It's a fascinating journey through the evolutionary roots of who we are!
