Intro

My guest today is Robin Dunbar. Robin is a biological anthropologist, evolutionary psychologist, and specialist in primate behavior. He is the man behind Dunbar’s number, a theory about the number of stable relationships we can maintain at once. Robin unravels the thread of research that led him to Dunbar’s number and describes how this plays into every single person’s layers of human connection. It was fascinating to hear how his findings on social circles have implications for optimally structuring businesses and organizations, as well as the idea of homophily, all of which Robin thoughtfully explains. It was a treat to get to explore these topics with Robin Dunbar himself so please enjoy this great conversation.
