The Science of Friendship

We are in the midst of a global friendship recession. And despite the strong social and evolutionary role friendship has played in our long human story, we have seen, in just one generation, a rapid decline in both the quantity and quality of friendships. This podcast digs deep into the science of friendship, from the changing nature of cooperation and competition, to why uncertainty in our world is altering the way we communicate, while activating our deepest and darkest competitive instincts. We discuss the effects of loneliness and its odd relationship with cortisol, as well as how loneliness can even alter our genetic expression. We look at why young men lead in friendlessness, and the burden this places on women. Finally, we look at the relationship between loneliness and purpose and what we can learn from U.S. Navy SEAL training's Hell Week.
