Here's another fantastic conversation with Justin Barrett, cognitive scientist extraordinaire, who spends his time at the intersection of science and religion. We dove deep into why developmental psychology is such a powerful lens for understanding human nature - turns out you can't figure out if a zebra is white with black stripes or black with white stripes just by looking at adult zebras, you've got to watch how they develop. Justin walked us through the fascinating story of human evolution and our hyper-sociality, from our massive brains (five to seven times bigger than expected for mammals our size!) to our unique ability to think about each other's thoughts about our thoughts. We explored how kids naturally develop agency detection, theory of mind, and teleological reasoning - basically why three-year-olds spontaneously ask "what's that mountain for?" and start wondering about invisible agents. Then we got into the weeds about how our Stone Age minds are navigating modern technologies like social media and AI, with Justin making a compelling case using his "kudzu analogy" about technologies that spread too fast for us to understand their consequences. From the crisis of masculinity to boomers getting radicalized during COVID lockdowns, we covered how our evolved psychology is both a gift and a vulnerability in our rapidly changing world.
