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 Gibson and Sean Penn, as well as The Men Who United the United States, The Map That Changed the World, The Man Who Loved China, A Crack in the Edge of the World, and Krakatoa. His books have been New York Times bestsellers and have appeared on numerous best-of-the-year lists. In 2006 he was appointed an Officer of the Order of the British Empire (OBE) by Her Majesty the Queen.

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 Are Smarter Than You Know.

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 as BBC, Forbes, NPR, and The Times. His new book is The Collective Edge: Unlocking the Secret Power of Groups.

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. 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.

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.
