Welcome back folks! The new season of Many Minds is quickly ramping up. On today's episode we're thrilled to be rejoined by Dr. Michael Muthukrishna. Michael is Associate Professor of Economic Psychology at the London School of Economics. He's an unusually wide-ranging and rigorous thinker; though still early in his career, Michael has already made key contributions to our understanding of culture, intelligence, evolution, innovation, cooperation and corruption, cross-cultural variation, and a bunch of other areas as well.
We wanted to have Michael back on—not just because he was an audience favorite—but because he's got a new book out. It's titled A theory of everyone: The new science of who we are, how we got here, and where we're going. In this conversation, Michael and I talk about the book and lay out that grand theory mentioned in the title. We discuss energy and how—since the very origins of life—it's proven to be a fundamental, unshakeable constraint. We talk about the nature of human intelligence and consider the dynamics of human cooperation and innovation. We also delve into a few of the implications that Michael's "theory of everyone" has for the future of our species. Along the way, we touch on carrying capacity, nuclear fusion, inclusive fitness, religion, the number line, multiculturalism, AI, the Flynn effect, and chaos in the brickyard.
If you enjoy this one, you may want to go back to listen to our earlier chat as well. But more importantly, you may want to get your hands on Michael's book. It's ambitious and inspiring and we were barely able to graze it here.
Alright friends, without further ado, on to my second conversation with Dr. Michael Muthukrishna. Enjoy!
