  Jared Diamond: How Much Can One Person Change History? 15.09.2026 1h 29m

  Would World War II have happened without Hitler? Would someone else have built Apple without Steve Jobs? Jared Diamond joins Michael Shermer to ask how much history depends on particular people. From Darwin's discoveries to the rise of Christianity, Diamond considers when someone is truly irreplaceable, when someone else would have done much the same thing, and how we can tell the difference. Jared Diamond is the Pulitzer Prize-winning author of the seminal million-copy-bestseller Guns, Germs, and Steel, which was named one of Time magazine's best non-fiction books of all time, Collapse, a No. 1 international bestseller, and The World Until Yesterday, among other books. A professor of geography at UCLA and noted polymath, Diamond's work has been influential in the fields of anthropology, biology, ornithology, ecology and history, among others. His new book is Profits, Prophets, Coaches, and Kings: (When) Do Leaders Matter?

  Why America Failed to Stop 9/11 | Gerald Posner & Michael Shermer 11.09.2026 42m

  How did 19 hijackers evade the world's most advanced intelligence apparatus despite years of warnings? Twenty-five years after 9/11, journalist Gerald Posner joins Michael Shermer to explain the security failures that left America vulnerable. Those failures, compounded by government secrecy, have helped sustain suspicions that officials orchestrated the attacks or deliberately allowed them to happen. What does the evidence show, and have we learned the right lessons?

  Why Be Honest When Cheating Pays? 09.09.2026 1h 45m

  Most of us think of ourselves as honest. But would we still tell the truth if lying got us what we wanted—and nobody would ever find out? Philosopher Christian Miller joins Michael Shermer to discuss his new book The Honesty Crisis and the uncomfortable gap between having a reputation for honesty and actually being honest. Christian B. Miller is the A.C. Reid Professor of Philosophy at Wake Forest University. He is the author of over 130 articles as well as several books. Thanks to a $4.4 million grant from the John Templeton Foundation, he directed The Honesty Project, one of the largest research initiatives ever undertaken on honesty. His new book is The Honesty Crisis: Preserving Our Most Treasured Virtue in an Increasingly Dishonest World.

  Is the Future Unknowable? Uncertainty, Free Will, and the Limits of Science 01.09.2026 1h 23m

  What if uncertainty isn't a temporary problem science will eventually solve, but a fundamental feature of reality? Neuroscientist Stuart Firestein joins Michael Shermer to make the case that the universe may be far less deterministic—and the future far less predictable—than we like to imagine. Firestein and Shermer discuss chaos and complexity, Darwin and randomness, free will, scientific progress, the replication crisis, COVID and the problem of communicating uncertainty, why humans are so bad at probability, and why even enormous amounts of data can fail to predict individual people or events. Stuart Firestein is a professor of neuroscience at Columbia University and a member of the Santa Fe Institute. He has published over one hundred scientific papers in journals such as Nature, Science, Cell, and Neuron. He is a Guggenheim fellow, a member of the advisory committee for the Alfred P. Sloan Foundation, and an elected fellow of the American Association for the Advancement of Science. His new book is It Could Be Otherwise: Science in the Age of Uncertainty.

  Why We Want to Believe in Aliens and Why We Still Haven't Found Them 25.08.2026 1h 13m

  UFOs were once the stuff of tabloids and conspiracy theories. Today they're the subject of congressional hearings, Pentagon investigations, mainstream news coverage, and a new wave of claims about government cover-ups and alien technology. Adam Kirsch, senior editor at The Atlantic and author of We Want to Believe: How Aliens Went Mainstream and Why It Matters, joins Michael Shermer to ask what changed—and why the idea of extraterrestrial visitors has such a powerful hold on us. They discuss Roswell, UFO "disclosure," eyewitness testimony, government secrecy, alien abductions, Carl Sagan and Contact, the religious impulse behind UFO belief, and the difference between testimony and scientific evidence. The conversation also turns to the serious scientific search for extraterrestrial intelligence: the Fermi paradox, why decades of SETI have found nothing, how rare intelligent life might be, and whether our ideas about aliens ultimately tell us more about ourselves than about anything actually out there. Adam Kirsch is the author of several books of poetry and criticism and a senior editor at The Atlantic. A 2016 Guggenheim Fellow, Kirsch has written for publications including The New Yorker, Slate, The Times Literary Supplement, The New York Times Book Review, Poetry, and Tablet. His new book is We Want to Believe: How Aliens Went Mainstream and Why It Matters.

  Is There a Second Arrow of Time? A New Law of Evolution, Information, and Complexity 18.08.2026 1h 18m

  Why does the universe produce ever more elaborate forms, from atoms and minerals to cells, organisms, brains, technology, and civilization? The familiar laws of physics can explain much of what happens in nature, but Robert Hazen and Michael Wong argue that something important has been missing: a law describing how evolving systems generate and select new forms over time. Michael Shermer speaks with Hazen and Wong about their proposed law of increasing functional information, the central idea behind their new book Time's Second Arrow. They discuss entropy and the second law of thermodynamics, the origin of life, the Cambrian explosion, emergence and complexity, Stephen Jay Gould and evolutionary contingency, whether evolution has a direction, and why the same basic process of variation and selection may apply far beyond biology.  Shermer also presses them on what evidence could falsify their theory, whether AI could evolve far faster than biological organisms, and the biggest question of all: Does any of this imply that the universe has a purpose? Robert M. Hazen, a geoscientist at the Carnegie Institution for Science, is the author of Symphony in C, among other titles. Michael L. Wong is a planetary scientist and astrobiologist at the Carnegie Institution for Science.

  Why Good People Disagree About Right and Wrong 11.08.2026 1h 57m

  Why do reasonable people disagree so strongly about right and wrong? And why are we so quick to assume that people on the other side of a moral or political issue are irrational, selfish, ignorant, or simply bad? Michael Shermer speaks with Cornell psychologist Audun Dahl, author of Between Fixed and Fickle: Why Our Moral Views Keep Changing, about how human morality develops and why many familiar explanations fall short. They discuss whether babies are born with a moral sense, what children and other primates can really tell us about the origins of morality, how parents shape their children's values, classic experiments in moral psychology, and whether science can tell us what is right and wrong. The conversation also turns to abortion, competing rights, immigration, religion, and the growing tendency to misunderstand and demonize people who reach different moral conclusions. Audun Dahl is a professor of psychology at Cornell University, where he directs the Developmental Moral Psychology Lab. His research examines how people develop ideas about right and wrong across the lifespan, from infancy through adulthood, and how moral judgments are shaped by everyday social interactions. He is the author of Between Fixed and Fickle: Why Our Moral Views Keep Changing.

  Are We Building a God? AI, Superintelligence, and the Coming Singularity 05.08.2026 1h 22m

  Robert Wright joins Michael Shermer to discuss his new book, The God Test: Artificial Intelligence and Our Coming Cosmic Reckoning, and why he thinks the AI revolution may be moving much faster than most people realize. Wright argues that deep learning is not just a new way of programming computers. In an important sense, it resembles evolution: neural networks discover solutions for themselves, sometimes recreating cognitive functions that natural selection built into human brains. That helps explain why AI capabilities have advanced so quickly, and why increasingly autonomous systems and recursive self-improvement could accelerate the process even further. Shermer presses Wright on what all of this actually means. Does an AI understand what it says? Could it be conscious? Why would a superintelligence ever seek power? Is human extinction a realistic possibility, or science-fiction doomerism? They discuss AI deception and theory of mind, John Searle's Chinese Room, bioweapons and cyberattacks, the risk of a U.S.-China AI arms race, regulation, surveillance, and the growing concentration of power in governments and tech companies. The conversation ends with Wright's larger philosophical question: if humanity really is building something with godlike power, what kind of god are we going to build, and are we mature enough to survive it? Robert Wright is the New York Times bestselling author of The Evolution of God (a finalist for the Pulitzer Prize), Nonzero, The Moral Animal, and Three Scientists and their Gods (a finalist for the National Book Critics Circle Award). He has taught at the University of Pennsylvania and at Princeton University, where he also created the popular online course "Buddhism and Modern Psychology." He is currently Visiting Professor of Science and Religion at Union Theological Seminary in New York.

  Can You Trust Wikipedia? Co-Founder Larry Sanger on Wikipedia's Bias and Why He Was Banned 30.07.2026 2h 3m

  Michael Shermer speaks with Wikipedia co-founder Larry Sanger shortly after Sanger was permanently banned from editing the site he helped create. Sanger tells the story of Wikipedia's founding, how its ideal of open collaboration hardened into a system dominated by a relatively small group of powerful editors, and why he believes its rules on sourcing and "consensus" now produce political and religious bias. In the second half of the conversation, Shermer and Sanger shift gears completely and discuss whether religious faith can be rational, the philosophical case for God, the resurrection, the Trinity, repentance and salvation, and whether a future superintelligent AI could become indistinguishable from God.

  How to Think Clearly About a World in Crisis: Iran, China, Russia, and the West's Economic Pessimism 18.07.2026 1h 4m

  Michael Shermer speaks with political scientist Marlene Laruelle about Russia's turbulent transformation during the 1990s and the rise of Vladimir Putin, why the Kremlin so badly misjudged Ukraine, China's rise and its ambitions regarding Taiwan, why killing Iran's Supreme Leader and much of its senior leadership did not bring down the regime, the limits of foreign aid and sanctions, mass surveillance, economic nationalism, and whether Western democracy can survive an age of economic pessimism and technological control. Marlene Laruelle is a professor in the Department of Political Science at Luiss University in Rome. From 2011 to 2025, she served as research professor of international affairs and political science at George Washington University. She directs the Illiberalism Studies Program, a transatlantic initiative based in Washington, D.C., and Paris at Inalco. A specialist in Russia and the post-Soviet region, her work examines ideology, geopolitics, and culture, with a current focus on the rise of illiberal and postliberal ideologies in Europe and the United States.

  The Truth About Sex Differences (Steve Stewart-Williams) 11.07.2026 55m

  How do men and women differ? Where do the differences come from? And how do they shape modern life? Drawing on a century of research and a billion years of evolution, Steve Stewart-Williams explains why many sex differences appear despite socialization, not because of it; why in our mating and parenting patterns, humans are more like the average bird than the average mammal; and why sex differences are sometimes a sign of societal health rather than injustice. Steve Stewart-Williams is a professor of psychology at the University of Nottingham Malaysia. His first book, Darwin, God, and the Meaning of Life, was published in 2010. His second, The Ape That Understood the Universe, was published in 2018. His new book is A Billion Years of Sex Differences.

  America at 250: What Did the Founders Get Right? 06.07.2026 17m

  Michael Shermer makes the case that the U.S. Founding Fathers were not only steeped in Enlightenment values on which the Declaration of Independence was based, but they were also scientists searching to discover moral truths and values on which to base a rational society, which they succeeded in doing in this document along with the Constitution.

  When History Goes on Trial: Demjanjuk, Eichmann, and Justice After Atrocity 27.06.2026 1h 32m

  John Demjanjuk lived for decades as a retired autoworker in suburban Cleveland. Then investigators accused him of being "Ivan the Terrible," one of the most notorious guards at Treblinka. What followed was one of the strangest and most troubling Nazi war-crimes cases of the postwar era: extradition, eyewitness testimony, a death sentence, a reversal, and a final prosecution many years later. In this episode, Michael Shermer talks with Lawrence Douglas, professor at Amherst College and author of The Criminal State: War Atrocity and the Dream of International Justice, about Demjanjuk, Eichmann, Nuremberg, Holocaust denial, and the problem of proving atrocities decades after they happened. How reliable is eyewitness memory after 40 or 50 years? What did Nuremberg actually establish? Was Eichmann really just a bureaucrat? And can a courtroom ever deliver justice for crimes almost too large to comprehend? Lawrence Douglas is the James J. Grosfeld Professor of Law, Jurisprudence, and Social Thought at Amherst College and a Guggenheim fellow. His many books include The Right Wrong Man and The Memory of Judgment. His writing has appeared in leading publications such as Harper's, The Wall Street Journal, and The Economist. His new book is The Criminal State: War Atrocity and the Dream of International Justice.

  Massimo Pigliucci on Doubt, Moral Courage, and Living Without Illusions 20.06.2026 1h 33m

  What does it mean to live well when certainty is unavailable? Michael Shermer speaks with Massimo Pigliucci about moral character, ancient philosophy, and the difficult art of making decisions without easy answers. The conversation moves from Cicero and Stoicism to the legacy of the New Atheism, asking why rejecting religion is not the same as having a philosophy of life. They discuss virtue ethics, moral dilemmas, effective altruism, faith, free will, democracy, human flourishing, and the uneasy relationship between facts and values. From the trolley problem and Peter Singer's drowning child thought experiment to the ethics of charity, the limits of utilitarian thinking, and the dangers of tribalism, this episode asks how we should act when rules fail, consequences are uncertain, and good intentions are not enough. Massimo Pigliucci is a bestselling author, philosopher, evolutionary biologist, and the K.D. Irani Professor of Philosophy at the City College of New York. His work spans evolutionary biology, philosophy of science, pseudoscience, and practical philosophy. His latest book is How to Be a Happy Skeptic: The Power of Doubt in a Meaningful Life.

  Cathy Young: Why Free Societies Need Free Speech 16.06.2026 1h 30m

  Cathy Young returns to the show for a wide-ranging conversation about free speech, institutional trust, and the strange incentives shaping public debate today. What happens when universities, media outlets, political movements, and online personalities trade careful thinking for moral certainty, tribal loyalty, or attention? Michael and Cathy discuss the pressure to excuse bad ideas when they come from "your side," the rise of activist thinking in education and journalism, and the growing appeal of contrarian figures who seem to thrive on distrust. They also get into the war in Ukraine, Israel and Gaza, Iran, isolationism, and why defending open inquiry matters most when it becomes inconvenient.

  The Zodiac Killer Wasn't Real 13.06.2026 1h 39m

  The Zodiac Killer has been treated for decades as America's ultimate unsolved true crime mystery: one mysterious killer, taunting letters, cryptic ciphers, a strange costume, and a trail of victims across Northern California. Eddie McNamara thinks that story is wrong. The victims were real, the crimes were real, but the single mastermind may have been a media-made myth. Eddie McNamara is the author of Zodiactually: The Real Story of a Fake Serial Killer, Toss Your Own Salad: The Meatless Cookbook, Brooklyn Hardcore, and Two Fare Zone. He's a former cop, 9/11 first responder, trained chef, and a columnist for Penthouse magazine.

  How Algorithms Use Your Data to Control You 09.06.2026 1h 34m

  Michael Shermer speaks with Oxford philosopher Carissa Véliz about the long human desire to know the future—from ancient oracles and astrology to AI, surveillance capitalism, predictive policing, and "data-driven" decision-making. Véliz argues that prediction is rarely neutral: the same machinery that collects personal data also tries to forecast behavior, and once institutions start treating predictions as facts, forecasts can become tools of control. The conversation gets into why privacy matters for democracy, how algorithms can turn human lives into self-fulfilling prophecies, and why extraordinary people often fall outside predictive models. Shermer and Véliz also discuss the limits of science, the replication crisis, crime statistics, effective altruism, utilitarian ethics, and free will. Carissa Véliz is an associate professor at the Institute for Ethics in AI at the University of Oxford. Her first book, Privacy Is Power (Melville House) was an Economist book of the year and has been published in seven languages. Her academic work has been published in The Harvard Business Review, Nature, AI & Society, and The American Journal of Bioethics, among others. Her new book is Prophecy: Prediction, Power, and the Fight for the Future, from Ancient Oracles to AI.

  Batya Ungar-Sargon: Why the Left Sees Jews Differently Now 06.06.2026 54m

  Batya Ungar-Sargon joins Michael Shermer for a wide-ranging conversation about the historical relationship between Jews and the American left, and why that relationship has become increasingly strained in recent years. The discussion begins with the reaction to October 7 and the political language that quickly emerged around Israel, Palestine, power, oppression, and resistance. From there, Ungar-Sargon traces a longer history: Jewish life in early America, Jewish involvement in the labor movement, the Triangle Shirtwaist Factory fire, the civil rights movement, and the role many Jews played in shaping progressive politics in the 20th century. Batya Ungar-Sargon is a columnist for The Free Press and the host of Batya! on NewsNation, where she is a weekend anchor. She holds a PhD in English from the University of California, Berkeley. Her new book is The Jews and the Left.

  From Equality to Equity: How Social Justice Becomes Ideology 03.06.2026 58m

  Jon Mills, a philosopher, psychoanalyst, and clinical psychologist, joins Michael Shermer to discuss how social justice ideology has moved from a concern with fairness and equal treatment into a rigid moral framework built around oppressors and victims, privilege and disadvantage, good and evil. Their conversation focuses on the tension between compassion and truth: how to take injustice seriously without reducing people to identity categories, what happens when clinicians bring activism into the therapy room, why biological reality has become politically charged, and whether "wokeness" is beginning to lose its hold on public life. Jon Mills is a Canadian philosopher, psychoanalyst, and clinical psychologist. He is Honorary Professor, Department of Psychosocial & Psychoanalytic Studies, University of Essex, UK, on faculty in the Postgraduate Programs in Psychoanalysis & Psychotherapy, Gordon F. Derner School of Psychology, Adelphi University, USA, and on faculty and a Supervising Analyst at the New School for Existential Psychoanalysis, USA. Recipient of numerous awards for his scholarship including 5 Gradiva Awards, he is the author and/or editor of over 35 books in psychoanalysis, philosophy, psychology, and cultural studies including most recently End of the World: Civilization and Its Fate.
