Christopher Beha grew up Catholic in Manhattan, walked away during the New Atheist era, and spent years trying to build a secular worldview sturdy enough to live inside. It didn't hold. So he kept reading—Hume, Kant, Russell, the existentialists—and kept chasing the questions that don't let you sleep: what counts as evidence, what belief even is, and what you do when reason can't answer the things you still have to decide.

In this conversation with Michael Shermer, Beha makes a case that skepticism and belief aren't enemies—and that some debates go nowhere because people are arguing about the "branches" while standing on totally different foundations.

Christopher Beha is the former editor of Harper's Magazine and the author of four previous books, including The Index of Self-Destructive Acts, which was nominated for the 2020 National Book Award. His new book is Why I Am Not an Atheist: The Confessions of a Skeptical Believer.

Michael Shermer recounts the moment he discovered his name in the Jeffrey Epstein files and uses it as a jumping-off point to tell a few unforgettable stories about con men he's encountered over the years, and how their tactics work.

Why do people risk everything for love but treat sex like it's no big deal? Why is intimacy the most expensive thing in a brothel? And why do jealousy, infidelity, and heartbreak push otherwise rational people into behavior they later can't explain?

Evolutionary biologist and sex researcher Justin Garcia, executive director of the Kinsey Institute and author of The Intimate Animal, joins Michael Shermer for a candid conversation about the biology of sex, the evolutionary logic of pair bonding, and why love—not lust—is what often pushes people past the point of reason.

Justin R. Garcia is an evolutionary biologist and sex researcher. He is Executive Director & Senior Scientist at the Kinsey Institute. He is also the Scientific Advisor to Match Group and Match.com, where he provides expertise to the company's annual Singles in America study. His research has been featured in outlets like The New York Times, The Wall Street Journal, USA Today, TIME, Cosmopolitan, and Vanity Fair. His new book is The Intimate Animal.

In this episode, Michael Shermer walks through the core ideas behind his new book Truth: What It Is, How to Find It, and Why It Still Matters, breaking down how humans confuse meaning with reality, stories with facts, and confidence with correctness.

He also explains why changing your mind is a strength, not a flaw; why extraordinary claims really do require extraordinary evidence; and why "just asking questions" isn't as innocent as it sounds.

"Michael Shermer reminds us that the search for truth is not a luxury, but a necessity. This book is a powerful argument for why reality matters and a practical toolkit for how to find it." ―Sabine Hossenfelder

"Michael Shermer has a fine record as a long-time crusader for evidenced rationality. This fascinating and wide-ranging book should further enhance his impact on current controversies." ―Lord Martin Rees

"Michael Shermer is one of our most influential intellectuals. Truth lances the myth of truth's subjectivity, arguing (provocatively) that truth can generate moral absolutes. This stimulating, excellent book inspires you to spread the word that the Earth is not flat and that truth matters." ―Robert Sapolsky

"Michael Shermer has spent his career grappling with the slipperiest word in our language: truth. As someone who knows firsthand what happens when truth gets lost in noise and narrative, I'm grateful for Shermer's clear-eyed insistence that truth is not only real, but necessary." ―Amanda Knox

"Michael Shermer pulls no punches: in a world where opinion too often masquerades as fact, he dismantles delusion and arms us with the tools to meet reality head-on." ―Brian Greene

In this solo episode of The Michael Shermer Show, Michael Shermer responds to the shooting of Alex Pretti, a 37-year-old healthcare worker who was killed by federal immigration agents in Minneapolis during protests over enforcement of immigration law.

As political debate intensifies, Shermer asks a tough question that most discussions are avoiding: What role does personal responsibility play in emotionally charged, high-risk situations?

He separates the facts we can reasonably assert from what remains uncertain and explains why scrutinizing frame-by-frame video misses something essential about how humans behave under stress and fear.

Michael Shermer sits down with attorney and bestselling author Kent Heckenlively for a tense, thoughtful, and surprisingly cordial conversation about UFOs, government secrecy, and the idea of "catastrophic disclosure."

Heckenlively argues that something real is being hidden. Not necessarily aliens, but information powerful enough to disrupt energy markets, military spending, and political authority. But beyond stories and secondhand testimony, where is the kind of evidence that would settle the question once and for all?

The episode takes up congressional hearings, whistleblowers, classified briefings, Cold War secrecy, optical illusions, advanced military technology, and why, after nearly 80 years, the UFO story continues to produce more questions than answers.

Kent Heckenlively is an attorney, science teacher, and New York Times bestselling author. His books have covered such topics as scientific fraud, bias at Google, Facebook, and CNN, promising medical therapies, as well as behind-the-scenes looks into the COVID-19 Task Force. His books have sold more than half a million copies. His new book is CATASTROPHIC DISCLOSURE: The Deep State, Aliens, and the Truth.

In this episode, Michael Shermer talks with filmmaker James Fox, whose work has helped push UFOs, now often called UAPs, out of the tabloid shadows and into congressional hearings, radar logs, and sworn testimony.

Fox has spent three decades interviewing fighter pilots, radar operators, intelligence officials, scientists, and firsthand witnesses. His conclusion is not that we know what these objects are, but that dismissing them no longer works. Around 90 to 95 percent of sightings collapse under scrutiny. The remaining cases do not.

The question is: What are we supposed to do with what's left?

James Fox is a film director widely regarded as one of the leading voices in UFO filmmaking. He is known for documentaries such as The Phenomenon, The Program, and Moment of Contact, several of which are frequently cited among the best UFO documentaries ever made.

What if the deepest human drive isn't happiness, survival, or even love, but the need to matter?

Philosopher and MacArthur Fellow Rebecca Newberger Goldstein joins Michael Shermer to discuss The Mattering Instinct, her argument that the desire to feel significant lies at the core of human behavior. That drive helps explain our greatest achievements, from creativity and moral courage to scientific and artistic excellence. It also helps explain some of our darkest outcomes, including extremism, violence, and ideological fanaticism.

Goldstein examines why people will give up comfort, status, and sometimes even their own lives to feel that they matter. She questions why meaning cannot be captured by happiness metrics or self-help formulas, and why the same psychological force can produce saints, scientists, athletes, cult leaders, and terrorists. The conversation moves through free will, entropy, morality without God, fame, narcissism, and the crucial difference between ways of mattering that create order and those that leave damage behind.

Rebecca Newberger Goldstein is an award-winning philosopher, writer, and public intellectual. She is the author of ten books of acclaimed fiction and non-fiction, including 36 Arguments for the Existence of God: A Work of Fiction and Betraying Spinoza: The Renegade Jew Who Gave Us Modernity. She holds a PhD in philosophy of science from Princeton University and has taught at Yale, Columbia, NYU, Dartmouth, and Harvard. A fellow of the American Academy of Arts and Sciences, her work has been supported by the MacArthur "Genius" grant and fellowships from the Guggenheim, Whiting Institute, Radcliffe Institute, and the National Science Foundation. Her new book is The Mattering Instinct: How Our Deepest Longing Drives Us and Divides Us.

In this unscripted solo episode, Michael Shermer reflects on a dizzying start to the year and what it reveals about truth, power, and public judgment. From events in Venezuela and the limits of exporting democracy to a viral Planet Fitness controversy, the Minneapolis ICE shooting, and renewed claims about aliens, Shermer keeps returning to the same question: What actually helps, and what only feels like a good idea in the moment?

What if the way we approach mental health is quietly making things worse?

Psychiatrist and psychotherapist Sami Timimi joins Michael Shermer to examine some of the core assumptions behind modern psychiatry. Why have diagnoses such as ADHD, autism, anxiety, and depression expanded so dramatically—and why hasn't increased access to treatment led to better outcomes at the population level?

Timimi describes how diagnostic categories have broadened over time and questions whether psychiatric labels function in the same way as medical diagnoses elsewhere in healthcare. Without clear biological markers, he argues, definitions can expand to include forms of distress that were once considered part of ordinary human experience.

The conversation also considers the role of meaning, identity, and culture in shaping how people understand psychological suffering. Timimi reflects on the limits of medication and therapy, the unintended consequences of the "mental illness as physical illness" model, and how social media may contribute to the spread and reinforcement of certain diagnostic categories.

Dr. Sami Timimi is a child and adolescent psychiatrist, psychotherapist, and Fellow of the Royal College of Psychiatrists. He has published more than 150 academic papers and authored or edited over a dozen books, including Naughty Boys, Liberatory Psychiatry, and The Myth of Autism. His new book is Searching for Normal: A New Approach to Understanding Mental Health, Distress, and Neurodiversity.

What is consciousness, really? Why does it not simply switch on at a single moment? Neuroscientist Niko Kukushkin explains how even single cells can show primitive forms of memory and agency, why the human mind is not a mysterious force floating above biology, and why reducing it to "just neurons" misses what actually matters.

He also discusses the evolutionary gamble of complexity, why bacteria still dominate the planet, and how abstraction and memory together give rise to thought.

At the center of the conversation is an unsettling question: Why does it feel so special to be you when science says that you are nothing but a chemical reaction—a collection of atoms and molecules, like rocks, paperclips, and everything else in the physical universe?

Nikolay Kukushkin is a clinical associate professor at New York University and a research fellow at NYU's Center for Neural Science, where he studies how temporal patterns shape memory formation. He holds degrees from St. Petersburg State University and Oxford University, and completed postdoctoral training at Harvard Medical School. He is the author of a recent paper in Nature Communications demonstrating canonical memory in non-neural cells. His book is One Hand Clapping.
