What do you do when someone believes you shouldn't exist? Daryl Davis didn't protest. He didn't shout. He sat down, asked questions, and kept showing up. Over decades, that approach has led more than 200 Ku Klux Klan members and white supremacists to walk away from their robes for good. In this conversation, Davis explains why people radicalize, and what happens psychologically when prejudice collides with a real human being. He shares stories from inside Klan meetings, lessons learned from neo-Nazis, and why today's climate of polarization may actually be an opportunity rather than a dead end. Daryl Davis earned his Bachelor of Music degree from Howard University and an Honorary Doctorate in Humane Letters from Post University. He is the author of Klan-Destine Relationships and the subject of the multi-award-winning documentary Accidental Courtesy, which chronicles his work in race reconciliation. A lifelong musician, he has performed with Chuck Berry and President Bill Clinton, and as an actor appeared in H

Open inquiry depends on the ability to ask uncomfortable questions and follow evidence wherever it leads. Eric Kaufmann argues that this norm is now under strain. Drawing on history, survey data, and political theory, Kaufmann outlines how certain identity categories came to be treated as morally sacred—and how that shift has reshaped debates about equality, free speech, and academic inquiry. The conversation examines the long roots of today's culture conflicts, the move from equal opportunity to equal outcomes, and why disagreement is increasingly interpreted as moral transgression rather than intellectual difference. At stake is what happens to liberal societies when some questions can no longer be asked, nd whether open inquiry can still be defended without abandoning concern for fairness and dignity Eric Kaufmann is a professor of politics and Director of the Centre for Heterodox Social Science at the University of Buckingham. He has written for The New York Times, Wall Street Journal, Times of London, Ne

Brain-computer interfaces are moving out of the lab and into real medical use. In this episode of The Michael Shermer Show, Michael Shermer talks with Dr. Matt Angle, founder and CEO of Paradromics, a neurotechnology company developing one of the most advanced high-data-rate brain implants in the world, similar to Neuralink. These devices record activity from individual neurons, making it possible to restore speech in people with paralysis, reconnect the brain to external devices, and potentially treat chronic pain and neurological disorders with far greater precision than existing approaches. Angle explains why progress in neuroscience has been limited not by biology, but by data—how much information we can actually read from the brain, and how fast. He describes how patients who can no longer speak may soon communicate fluently using only brain signals, why invasive implants can sometimes be safer than long-term drug treatments, and what it takes to bring a brain implant through FDA approval and into the cl

At the turn of the 20th century, millions of Americans, including elite scientists, major newspapers, and cultural icons, were convinced that Mars was home to an advanced civilization. In this episode, Michael Shermer speaks with award-winning science journalist David Baron about one of the most astonishing episodes in scientific-cultural history. Blurry telescopes, mistranslated words, and persuasive personalities transformed speculation into accepted fact, while more cautious scientists struggled to be heard. The discussion covers Percival Lowell's Martian canals, Nikola Tesla's claim to have detected signals from another planet, and the role of mass media and early science fiction in fueling public belief. The episode also connects this forgotten moment to present-day debates about UFOs, alien megastructures, and the search for extraterrestrial intelligence, raising broader questions about how scientific ideas spread and why some claims capture the public imagination. David Baron is an award-winning journa

What if the great discoveries of science came in the "wrong" order? The Laws of Thermodynamics were discovered well after the creation of algebra, classical physics, and chemistry, but are perhaps much more important to our basic understanding of the universe. Chris Edwards argues that AI will be able to understand science outside of the traditional chronological developments of the sciences, unlocking entirely new potentials and perspectives on the universe. If human scholars are to understand how AI interprets the universe, we will first need to understand the scientific narrative in a "new order." Chris Edwards teaches history, English, and mathematics at a public school in the Midwest. He is a frequent contributor to Skeptic magazine and the author of Thought Experiments: History and Applications for Education, Beyond Obsolete: How to Upgrade Classroom Practice and School Structure, Femocracy: How Educators Can Teach Democratic Ideals and Feminism, and most recently of The New Order: How AI Rewrites the N

Criminal profiling promises certainty in the face of horror: this is what a killer looks like, this is how they think, this is how we stop them. But what if that promise is mostly an illusion? In this episode, Michael Shermer is joined by journalist and author Rachel Corbett to dismantle the myths behind criminal profiling, from the FBI's Behavioral Science Unit to our obsession with serial killers, mindhunters, and "psychological fingerprints." Corbett explains why randomness is harder to accept than evil, and how our hunger for neat explanations can actually make us less safe. Plus, the legacy of MKUltra and Ted Kaczynski, the seductive appeal of true crime, and the uncomfortable truth behind the "Jekyll and Hyde" problem: monsters rarely look like monsters. Rachel Corbett is a features writer at New York magazine, and her writing has also appeared in The New Yorker, The New York Times, and The Atlantic. She is the author of You Must Change Your Life, which won the Marfield Prize, the National Award for Art

For nearly two centuries, international relations have been premised on the idea of the "Great Powers." As the thinking went, these mighty states—the European empires of the nineteenth century, the United States and the USSR during the Cold War—were uniquely able to exert their influence on the world stage because of their overwhelming military capabilities. But this conception of power fails to capture the more complicated truth about how wars are fought and won.  Our focus on the importance of large, well-equipped armies and conclusive battles has obscured the foundational forces that underlie military victories and the actual mechanics of successful warfare. Phillips O'Brien suggests a new framework of "full-spectrum powers," taking into account all of the diverse factors that make a state strong—from economic and technological might, to political stability, to the complex logistics needed to maintain forces in the field.  Drawing on examples ranging from Napoleon's France to today's ascendant China, he of

In this episode of The Michael Shermer Show, Michael sits down with two giants of mind and machine science: Jay McClelland, one of the founders of modern neural networks, and Gaurav Suri, computational neuroscientist and director of the RAD Lab. Drawing from decades of research, they walk us through the revolution from behaviorism to cognitive psychology to modern neuroscience, and why simple interacting units can give rise to astonishingly complex behaviors.  From why we perceive letters differently in context to how memory works, why consciousness remains baffling, and what AI is (and isn't) actually doing, this episode dives deep into the mechanics of all levels of thought, mind, and even consciousness. Jay McClelland is a professor of psychology and of computer science and linguistics at Stanford University. He is one of the most influential and well-known cognitive scientists of the past century. He is the founder of the study of artificial neural networks, and his publications have been cited more than

Astrobiologist Caleb Scharf joins Michael Shermer for a wide-ranging conversation about the past, present, and future of our relationship with space. Drawing on his new book The Giant Leap, Scharf explains why human expansion beyond Earth may be less a choice than an evolutionary development, and he walks through the physics, history, and personalities that shaped our journey off the planet. Scharf also explains the biological toll of radiation and microgravity, and why terraforming Mars is probably unrealistic and why our future might rely more on building vast rotating habitats in space than on settling other planets. Caleb Scharf is an astrobiologist and recipient of the 2022 Carl Sagan Medal. He was Director of Astrobiology at Columbia University in New York and is now the Senior Scientist for Astrobiology at the NASA Ames Research Center in Silicon Valley. He is author of more than 120 scientific papers and over 500 popular science articles. His new book is The Giant Leap: Why Space is the Next Frontier

In this episode, Michel-Yves Bolloré lays out his case for why modern cosmology, fine-tuning, and the limits of materialism point toward a creator. Drawing on physics, thermodynamics, probability, and philosophy, he argues that the Big Bang, the apparent beginning of the universe, and the complexity of life collectively form a compelling body of evidence for God's existence. Bolloré explains why he believes the universe is not eternal, why "nothing" cannot produce "something," how moral red lines suggest a transcendent source, and how he reconciles scientific reasoning with his Christian faith, while Michael Shermer gently but rigorously presses him with questions to elicit his strongest arguments. Michel-Yves Bolloré is an engineer and entrepreneur whose career spans industrial innovation and philanthropic investment in education. He is a graduate of the École Nationale Supérieure d'Ingénieur de Toulouse and Paris-Dauphine University (Master of Science and Doctorate in Business Administration). He founded se

Have you ever thought about the science and history of … wind? In this episode, Simon Winchester explains why eastbound flights are usually faster than flying west, and how the discovery of the jet stream was almost missed because the original research was published in Esperanto. He also talks about the debate over the Great Terrestrial Stilling—the idea that global wind speeds may be decreasing—and why newer measurements suggest the trend may be reversing. Winchester describes how and where the highest wind speed ever recorded was measured, the increasing frequency of clear-air turbulence (the kind that causes sudden drops during flights), why only one flag placed on the Moon fell, the techniques used by Polynesian navigators to cross vast stretches of ocean without instruments, and the challenges faced by early wartime pilots who unintentionally flew into the jet stream. Simon Winchester is the acclaimed author of many books, including The Professor and the Madman, which was adapted into a film starring Mel

In this episode, Angus Fletcher explains why the human brain doesn't work like a computer and why our deepest strengths come not from logic or data processing but from imagination, emotion, and the ability to invent new futures. Drawing on neuroscience, Shakespeare, evolutionary biology, and his work with U.S. Army Special Operations, Fletcher shows how storytelling is the brain's oldest "technology," why intelligence is rooted in action rather than analysis, and what most people get wrong about creativity and common sense. Angus Fletcher is a professor of story science at Ohio State's Project Narrative, the world's leading academic think tank dedicated to understanding how stories work. He earned his PhD from Yale, conducted postdoctoral research at Stanford, and in 2023 received the U.S. Army's Commendation Medal for his groundbreaking work with Army Special Operations on primal intelligence. He has also written screenplays for major Hollywood studios and networks. His new book is Primal Intelligence: You A

War begins in the human mind long before it unfolds on the battlefield. In this episode, Michael Shermer sits down with Nicholas Wright, a neurologist, neuroscientist, security strategist, and advisor to the Pentagon, to explore one of the biggest questions of our time: why do humans fight, and how does the brain shape violence, leadership, and geopolitical decision-making? Nicholas Wright is a member of the Royal Colleges of Physicians and a neuroscientist who researches the brain, technology, and security at University College London, Georgetown University, and the Center for Strategic and International Studies in Washington, DC. He worked as a neurology doctor in London and Oxford, and has published numerous academic papers which have been covered by the BBC and The New York Times. His new book is Warhead: How the Brain Shapes War and War Shapes the Brain.

Why do smart people join dangerous cults, follow bad leaders, or stay silent when they know something's wrong? In this episode, Michael Shermer talks with organizational psychologist Colin Fisher about the science of group dynamics and conformity. From jazz bands to political mobs, Fisher explains how our evolutionary need to belong both unites and blinds us. He discusses the psychology of revenge, polarization, social media extremism, and why our brains are wired to dehumanize "the other." What makes a group innovative instead of dogmatic? And how close are we—really—to turning everyday politics into a cult? Colin M. Fisher is an Associate Professor of Organizations and Innovation at University College London's School of Management. His research focuses on helping groups and teams in situations requiring creativity, improvisation, and complex decision-making. He has written about group dynamics for both popular science and management audiences, and his work has been profiled in prominent media outlets such a

In this episode, Michael Shermer explores anomalous experiences through personal anecdotes and historical examples. He reflects on how to balance healthy skepticism with open-mindedness, and how to reckon with the very real emotional significance of such experiences—regardless of the scientific explanations behind them.

A former senior intelligence officer explains how espionage is evolving in the age of AI and amid rising global tensions with China, and why the mass harvesting of data affects not just nation-states, but all of us. The discussion also explores the history of spying, what life is really like for intelligence officers, and major intelligence failures and scandals, including 9/11 and Edward Snowden's unauthorized disclosures about the NSA. Anthony Vinci served as the first Chief Technology Officer at the National Geospatial-Intelligence Agency (NGA). Earlier in his career he served in Iraq, Africa, and Asia. He is an Adjunct Senior Fellow at the Center for a New American Security (CNAS) and received his PhD in International Relations from the London School of Economics. His new book is The Fourth Intelligence Revolution: The Future of Espionage and the Battle to Save America.

Archaeologist Ken Feder sheds light on how archaeology separates evidence from wishful thinking and entertaining storytelling. He explains what rock art, radiocarbon dating, and DNA can really tell us about the first peoples of the Americas, and talks about the different theories about ancient human migration and the impact of European contact on Native American populations. 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. Hi

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.

Are we entering a Fifth Great Awakening—a cultural swing back toward religion? An increasing number of books and articles are calling for a religious revival. “We need religion to keep our society functioning.” “People need meaning.” Michael Shermer responds to and revisits the historical waves of religious fervor that shaped American life. He also asks what today’s renewed interest in faith, spirituality, and meaning says about our culture. Featuring commentary on new books by Ayaan Hirsi Ali and Charles Murray, and a preview of Helen Pluckrose’s new article for Skeptic.
