Bryan and Hunter enter the dojo of the mind with Joe Henrich, master of our first fundamental of the mind: cultural accumulation. As regular listeners will know, in his book The Secret of Our Success, Henrich lays out the case for why problem solving and critical thinking are not humanity's great superpower. Rather, our great superpower is social intelligence. It is our ability to pass on culture from generation to generation that makes us so successful and able to conquer everywhere from the tundra to the desert to being able to venture out into space. This idea is the fundamental that is going to allow all of us to make sense of the seemingly chaotic world and benefit from rather than being hurt by the clash of cultures.
