#47: Robin Dunbar - The Chemistry of Connection

Episode SummaryThe equally erudite and jovial Robin Dunbar joins Jef Szi and the How Humans Work Podcast for the first of a two part conversation about limits and leaps of social patterns in primates and humans. An Oxford University professor of evolutionary psychology and someone with a facile grasp of multiple sciences and histories, Professor Dunbar offers us a fascinating account of the social roots of human nature. In part 1—The Chemistry of Connection—we dive deeply into the endorphin system and the how it functions to stabilize social bonds in groups. We come to see freshly how critical a role endorphins play in our day to day reality. Drawing on his rich understanding of touch, primates, and the wildly comprehensive health benefits endorphins, Dunbar illustrates the connections between chemistry, evolution, and the roots of social blueprint—translating it into the very familiar ‘raw feels’ of relationships that inform how we see, think, and feel about the world. In particular, Robin clarifies how and why social grooming assists us in dealing with unique social stresses that accompany a group survival strategy that primate species have. Further, Robin mirthfully shows us the unique elements of the human social tool kit, which activates social glue of endorphins without the time intensive work of touch. Indeed, the social tool kit of humans relies on the beautiful elements of laughter, dancing, singing, feasting, storytelling, and rituals to foster social cohesion. The Chemistry of Connection helps us in on our search for to understand what Social Cohesion is and how we can more successfully find it. Thank you Robin, it was a brilliant blessing to learn so much about human nature and our human story with you!***** About: Robin Dunbar: Professor Dunbar is Emeritus Professor of Evolutionary Psychology at Oxford University. His work in the Experimental Psychology department at the Magdalen College is concerned with ‘trying to understand the behavioral, cognitive and neuroendocrinological mechanisms that underpin social bonding in primates (in general) and humans (in particular).’ Robin is the author of several books, including The Social Brain, Human Evolution, and Friends: Understanding the Power of Our Most Important Relationships. Professor Dunbar is known for advancing the Social Brain Hypothesis with Dunbar’s Number. *****Episode #47TakeawaysSociality is a key evolutionary adaptation for survival.Group living helps solve problems of reproduction and defense.Primates invest heavily in maintaining social relationships.Social grooming triggers the endorphin system, promoting bonding.Humans have developed social tools like singing and dancing to bond.The endorphin system acts as a natural antidepressant.Addiction to opiates can diminish social engagement.Oxytocin plays a role in mother-infant bonding and romantic relationships.Endorphins provide pain relief and promote feelings of well-being.The evolution of sociality is complex and multifaceted.
