Would You Want to Know If You Were Wrong?

2026/09/28

What do you make of an experience you can't explain? A strange light in the sky, a book flying off a desk, a coincidence that feels too improbable to be chance? Social psychologist Barry Markovsky joins Michael Shermer to discuss his new book Everyday Extraordinary and the experiences that have kept him studying paranormal beliefs for decades—including his own childhood UFO sighting and a supposedly haunted vape shop. Markovsky explains how friends, communities, and our sense of who we are shape

Does Consciousness Break the Laws of Physics?

The Michael Shermer Show ·

2026/09/22

If we could explain everything happening in your brain, would there still be something left to explain about you? Physicist Avshalom Elitzur thinks so—and argues that accounting for consciousness may require changing the laws of physics. In this lively conversation, Michael Shermer challenges Elitzur on why subjective experience should be anything more than a product of the brain, whether an AI could be conscious, and what a hypothetical human without consciousness would have to say about any of

Jared Diamond: How Much Can One Person Change History?

The Michael Shermer Show ·

2026/09/15

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

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?

The Michael Shermer Show ·

2026/09/09

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

2026/09/01

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

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

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

Why Good People Disagree About Right and Wrong

2026/08/11

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

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

2026/07/30

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

The Truth About Sex Differences (Steve Stewart-Williams)

The Michael Shermer Show ·

2026/07/11

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

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.

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

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

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?

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.

How Algorithms Use Your Data to Control You

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
