We live in a world that seems more divisive and polarized than ever, and it’s common to describe this phenomenon as tribalism. But Michael Morris, professor at Columbia Business School, says that term is often misunderstood and that tribal instincts can in fact be very positive influences in society and at work. He uses the lens of cultural psychology to explain the deep-seated instincts behind the human need to join and identify as a group. And he breaks down how team managers and organizational leaders can leverage tribal instincts in positive ways strengthen workplace culture. Morris is the author of the new book Tribal: How the Cultural Instincts That Divide Us Can Help Bring Us Together.
