Archaeologist Ken Feder sheds light on how archaeology separates evidence from wishful thinking and entertaining storytelling.

He also shares what we know about Atlantis, the Lost Tribes of Israel, and what to make of Graham Hancock's visions of an ancient apocalypse. Kenneth L. Feder is professor emeritus of anthropology at Central Connecticut State University. His new book is Native America: The Story of the First People.

Michael Shermer sits down with Charles Murray (author of The Bell Curve, Coming Apart, and now Taking Religion Seriously) for a riveting 100-minute conversation about Murray's late-life turn from Harvard-bred agnosticism ("Smart people don't believe that stuff anymore") to Bayesian theism ("I put the afterlife at just over 50%"). This wide-ranging discussion explores the evidence for the existence of God and the afterlife, the problem of evil, and the historical growth of Christianity. They also delve into topics such as the nature of consciousness, terminal lucidity, and even evolutionary vs. religious perspectives on love. A thought-provoking exploration for skeptics, seekers, and anyone wondering whether the universe has a purpose. Charles Murray is a policy analyst educated at Harvard and MIT and currently serves as the Hayek Emeritus Scholar at the American Enterprise Institute. He is the author of several influential books, including the controversial The Bell Curve, Coming Apart, and Facing Reality. His most recent book is Taking Religion Seriously.

In this episode, Harvard primatologist Christine Webb challenges one of our deepest beliefs: that humans stand apart from the rest of nature. She traces the roots of human exceptionalism from Aristotle and Descartes to modern science, and explains why we still cling to hierarchies of intelligence. While most critiques of human exceptionalism focus on our moral obligation toward other species, Webb argues that they overlook what humanity stands to gain by letting go of its illusions of uniqueness and superiority. Christine Webb is a primatologist at Harvard's Department of Human Evolutionary Biology, with expertise in social behavior, cognition, and emotion. Her new book is The Arrogant Ape: The Myth of Human Exceptionalism and Why it Matters.

For many decision scientists, their starting point—drawn from economics—is a quantitative formula called Rational Choice Theory, allowing people to calculate and choose the best options. The problem is that this framework assumes an overly simplistic picture of the world, in which different types of values can be quantified and compared, leading to the "most rational" choice. Behavioral economics acknowledges that irrationality is common but still accepts the underlying belief from economics of what a rational decision should look like. Drawing from economics, psychology, and philosophy—and both inspired by and challenging Daniel Kahneman's Thinking, Fast and Slow—Barry Schwartz shows how the focus on rationality, narrowly understood, fails to fully describe how we think about our decisions, much less help us make better ones. Barry Schwartz is professor emeritus of psychology at Swarthmore College and visiting professor at Haas School of Business, University of California, Berkeley. His research and writing focus on the intersection of psychology and economics, particularly with regard to decision-making, intrinsic and extrinsic motivation, and the nature of human values. His books include The Paradox of Choice, Why We Work, and (as coauthor) Practical Wisdom. His new book, co-authored with the philosopher Richard Schuldenfrei, is Choose Wisely: Rationality, Ethics, and the Art of Decision-Making.

Why do we crave revenge? And why can't we stop? In this episode, James Kimmel explains the neuroscience behind one of our most destructive urges. Drawing from his new book, The Science of Revenge: Understanding the World's Deadliest Addiction, Kimmel reveals how revenge activates the same brain circuits as drugs like cocaine—and why even imagining payback can feel euphoric. If you've ever fantasized about revenge (and who hasn't?), whether in politics or personal relationships, this episode offers a chilling yet hopeful look at the science of moral outrage and redemption. James Kimmel, Jr., JD, is a lecturer in psychiatry at the Yale School of Medicine, a lawyer, and the founder and co-director of the Yale Collaborative for Motive Control Studies. A breakthrough scholar and expert on revenge, he first identified compulsive revenge seeking as an addiction and developed the behavioral addiction model of revenge as a public health approach for preventing and treating violence. His new book is The Science of Revenge: Understanding the World's Deadliest Addiction—and How to Overcome It.
