In this podcast, Jordan Peterson and Mark Changizi engage in a fascinating conversation about evolutionary biology and psychology, with a particular focus on perception, emotion, language, and social behavior. Changizi shares intriguing ideas, suggesting that our ability to see in color evolved not just for identifying fruits, but primarily to pick up on subtle emotional cues in facial blood flow. He also discusses how forward-facing eyes developed to enhance our vision in cluttered environments. The duo explores the deep connection between emotion and language, positing that emotional expressions are fundamental to communication and negotiation, even when words are absent. Additionally, they examine the importance of reputation in social interactions, both online and offline, and the difficulties of fostering a truthful and functional public discourse in the digital age.
