The Michael Shermer Show

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...

Francis Crick is best known as one of the figures behind the discovery of the double-helix structure of DNA, but the familiar story leaves out as much as it explains. Historian of science Matthew Cobb looks closely at how Crick's life actually unfolded, revealing a career shaped less by inevitability than by luck, conflict, false starts, and a series of highly contingent moments.

The double helix itself may have been waiting to be found, but what followed was anything but predetermined. Crick's influence came from asking uncomfortable questions about what the structure of DNA implied for genetics...

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...

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 wh...

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...

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...

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...

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.<...

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 t...

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, t...

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.<...

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 qu...

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 t...

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...

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...

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 cu...

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...

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...

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...

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...

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.

Pulitzer-winner Caroline Fraser maps the lives and crimes of Ted Bundy and his infamous peers—the Green River Killer, the I-5 Killer, the Night Stalker, the Hillside Strangler, and even Charles Manson—and explores an intriguing hypothesis: might environmental factors have played a role in the rise of serial killers in the 1970s and '80s?

Caroline Fraser is the author of Prairie Fires: The American Dreams of Laura Ingalls Wilder, which won the Pulitzer Prize. She is also the author of God's Perfect Child: Living and Dying in the Christian Science Church, and her writing has appe...

First installment of our new series Shermer Says. 

Topics covered:

For many decision scientists, their starting point—drawn from economics—is a quantitative formula called Rational Choice Theory, allowing people to calculate and choose the best options.

The problem is that this framework assumes an overly simplistic picture of the world, in which different types of values can be quantified and compared, leading to the "most rational" choice. Behavioral economics acknowledges that irrationality is common but still accepts the underlying belief from economics of what a rational decision should look like.
 
Drawing from economics, psychology, and philosophy—and both inspired by and challenging Daniel Kahneman's Thinkin...

Why do we crave revenge? And why can't we stop? In this episode, James Kimmel explains the neuroscience behind one of our most destructive urges. Drawing from his new book, The Science of Revenge: Understanding the World's Deadliest Addiction, Kimmel reveals how revenge activates the same brain circuits as drugs like cocaine—and why even imagining payback can feel euphoric.

If you've ever fantasized about revenge (and who hasn't?), whether in politics or personal relationships, this episode offers a chilling yet hopeful look at the science of moral outrage and redemption.

James Kimmel, Jr., JD, is...

What really defines a cult—and why do smart, well-intentioned people get caught up in them? In this episode, Michael Shermer sits down with cult intervention specialist Ashlen Hilliard to explore the psychology of high-control groups and the people drawn into them. Her work has been featured in prominent media outlets like Hulu, NewsNation, HuffPost, and BET+.

In 2022, Ashlen founded People Leave Cults, offering intervention and recovery resources for survivors and concerned loved ones. As one of the few Cult Intervention Specialists in the country, Ashlen consults with a team of experts to develop personalized intervention strategies fo...

Michael Shermer sits down with economist and Franklin descendant Dr. Mark Skousen to explore the wit, wisdom, and modern relevance of Benjamin Franklin, the man who bridged science, politics, and philosophy like no other. Shermer and Skousen discuss Franklin's contributions to science, moral philosophy, economics, and religious thought, while asking: What would Franklin make of today's America—its economy, politics, and culture?

Mark Skousen holds the Doti-Spogli Chair of Free Enterprise at Chapman University. Known as "America's Economist," he is the editor of Forecasts & Strategies, an award winning investment newsletter, and producer of FreedomFest, "the world's largest ga...

The COVID-19 pandemic was a devastating global event, killing more than seven million people, straining the fabric of societies, and shaking the foundations of the world economy. And yet, as horrifying as the experience was, COVID-19 was not "The Big One" — the dreaded pandemic that haunts the nightmares of epidemiologists and public health officials everywhere. That far deadlier outbreak is still ahead of us, and it will reshape life across the planet unless we're ready for it.

In this episode, Dr. Michael Osterholm, one of the world's leading infectious disease experts, explains what we got wrong, what we...

Common knowledge is necessary for coordination, for making arbitrary but complementary choices like driving on the right, using paper currency, and coalescing behind a political leader or movement. It's also necessary for social coordination. Humans have a sixth sense for common knowledge, and we create it with signals like laughter, tears, blushing, eye contact, and blunt speech.

But people also go to great lengths to avoid common knowledge—to ensure that even if everyone knows something, they can't know that everyone else knows they know it. And so we get rituals like benign hypocrisy, veiled bribes and th...

Jim Lampley's story is a 50-year travelog of an unlikely career that catalogs the evolution of sports television—from his emergence as the first sideline reporter, through hosting and covering 14 Olympics, to working with all major sports networks.

In this episode, Lampley reflects on his experiences in boxing, the evolution of the sport, and the genius of athletes like Muhammad Ali and George Foreman. The conversation also explores the unpredictability of life and how chance events shape our paths, the importance of mentorship, and the impact of performance-enhancing drugs.

Lampley offers insights into the current st...

In this solo commentary, Michael Shermer reflects on the assassination of Charlie Kirk and places it in the larger context of political violence, the psychology of radicalization, the dangers of false beliefs, and the role of free speech in intellectual discourse.

Science writer Nicholas Wade explains how human nature continues to shape—and sometimes destabilize—modern civilization, and argues that ignoring the effects of human nature on politics is one of society's greatest mistakes.

Drawing on anthropology, evolutionary biology, and history, Wade shows how deep-rooted traits not only shape the outcomes of certain political beliefs and systems, but also affect how people form families, religion, and social order.

Nicholas Wade has worked at Nature and Science, and, for many years, at The New York Times, where he was an editorial writer and science editor. He is the...

Parenting today often feels like an uphill battle, with technology invading every corner of our kids' lives. From the rise of social media addiction to the growing mental health crisis among children and teens, parents are grappling with how they can create a healthy, balanced relationship with technology for their kids.

Drawing on her decades as a psychologist studying the impact of technology and mental health, Jean Twenge offers evidence-based advice for raising independent and well-rounded children.

Jean Twenge, a professor of psychology at San Diego State University and the author of more than 190 scientific...

In this episode of The Michael Shermer Show, Michael Shermer interviews Alan Stern, a prominent planetary scientist and astronaut. Stern discusses his recent suborbital flight, the differences between government and private space initiatives, and the scientific implications of UFO sightings. He also shares insights about the evolution and future of space exploration, including details about the rarely talked about upcoming termination of dozens of already paid-for NASA missions.

Alan Stern is a planetary scientist, astronaut, and author. NASA has selected him to be the first researcher NASA funded to fly to space as a crewmember aboard a...

In a radical new story about the birth of our species, evolutionary biologist Madeleine Beekman argues that it was not hunting, fighting, or tool-making that forced early humans to speak, but the inescapable need to care for our children.

Beekman reveals the "happy accidents" hidden in our molecular biology—DNA, chromosomes, and proteins—that led to one of the most fateful events in the history of life on Earth: our giving birth to babies earlier in their development than our hominid cousins the Neanderthals and Denisovans. Faced with highly dependent infants requiring years of nurturing and protection, earl...

Economist Dean Spears explains the forces driving global population change, from past fears of overpopulation to today's concerns about declining birth rates.

He contrasts the perspectives of biologists and economists on population growth and highlights the role of human ideas and innovation in sustaining progress. Spears also discusses misconceptions about zero-sum economics, the links between population, health, and economic well-being, and the rise of anti-natalism.

The conversation covers population size and environmental concerns, government policies on family planning, and why cultural attitudes toward reproduction may be as important as policy in addressing the challenges of...

Because brainwashing affects both the world and our observation of the world, we often don't recognize it while it's happening―unless we know where to look. As Rebecca Lemov writes in her new book The Instability of Truth, "Brainwashing erases itself." What we call brainwashing is more common than we think; it is not so much what happens to other people as what can happen to anyone.

In her work, Lemov exposes the myriad ways our minds can be controlled against our will, from the brainwashing techniques used against American POWs in North Korea to the "soft" br...

In an era of globalized education, where ideals of freedom and inquiry should thrive, an alarming trend has emerged: foreign authoritarian regimes influencing American academia.

In her new book Authoritarians in the Academy, Sarah McLaughlin reveals how higher education institutions—long considered bastions of free thought—are compromising their values for financial gain and international partnerships.

Her investigation uncovers the subtle yet sweeping influence of authoritarian governments, exposing university leaders who prioritize expansion and profit over the principles of free expression. She also describes incidents in which professors and administrators weighed the costs of offending repr...

In this conversation, Michael Shermer and Dr. Eric Topol discuss the realties of aging, with particular focus on the role of AI in enhancing patient care and disease prevention, the importance of lifestyle factors, and the limitations of genetic testing in predicting health outcomes.

Topol also explains the dangers of ultra-processed foods, their link to inflammation, and the role of GLP-1 drugs in promoting healthier eating habits. The conversation also covers diet, particularly the differences between chicken and red meat, and the significance of sleep for overall health. Plus, consumption of microplastics, cholesterol management and statins, the...

Isabelle Boemeke explains how nuclear energy is our best option for ensuring the future of the planet—it can power cities, desalinate water, create carbon-free fertilizer, and heat homes, all with the smallest environmental footprint of any energy source. She also discusses common objections to nuclear energy, including safety concerns and waste management, the potential of microreactors, and the importance of nuclear energy in space exploration.

Isabelle Boemeke is a nuclear electricity educator. Her new book is Rad Future: The Untold Story of Nuclear Electricity and How it Will Save the World.

In his new book Coming Clean, Eric Heinze rejects the idea that we should be less woke. In fact, we need more wokeness, but of a new kind. Yes, we must teach about classism, racism, colonialism, patriarchy, and other gross injustices, but we must also educate the public about the left's own support for regimes that damaged and destroyed millions of lives for over a century—Stalin in the Soviet Union, Mao Zedong in China, Pol Pot in Cambodia, or the Kim dynasty in North Korea.

Criticisms of Western wrongdoing are certainly important, yet Heinze explains that mo...

Traditional religion in the United States has suffered huge losses in recent decades. The number of Americans identifying as "not religious" has increased remarkably. Religious affiliation, service attendance, and belief in God have declined. More and more people claim to be "spiritual but not religious." Religious organizations have been reeling from revelations of sexual and financial scandals and cover-ups. Public trust in "organized religion" has declined significantly. Crucially, these religious losses are concentrated among younger generations. This means that, barring unlikely religious revivals among youth, the losses will continue and accelerate in time, as less-religious younger Americans replace older...

In this episode, Michael Shermer speaks with historian Sophia Rosenfeld about how modern notions of personal choice—from Amazon shopping to Tinder swipes—emerged from centuries of cultural, religious, political, and economic transformation. Was there ever a time when choice wasn't synonymous with freedom? Why were early ideas of "common sense" and "free will" so limited? And what happens when choice itself becomes overwhelming?

From Enlightenment ideals to the sexual revolution and the abortion debate, Rosenfeld traces how our expanding range of options—and the meaning we attach to them—has shaped everything from our romantic lives to our p...

What can a lifetime of scientific discovery teach us about the universe—and ourselves? In this wide-ranging conversation, Michael Shermer sits down with Lord Martin Rees, renowned cosmologist, astrophysicist, and former Astronomer Royal, to reflect on the forces that shape scientific success, from personal luck to cultural context. Rees shares insights on the mysteries of cosmology, the search for extraterrestrial life, and the paradoxes that still puzzle humanity.

Rees also shares intimate reflections on his friend and Cambridge colleague Stephen Hawking, thoughts on Fermi's Paradox, and why some truths may forever lie beyond human comprehension.

When you are faced with a decision, do you consider the best outcome, or do you consider your deepest values about which actions are appropriate? Steven Sloman contrasts these two primary strategies for making decisions: consequentialism or prioritizing one's sacred values. He argues that, while both modes of decision making are necessary tools for a good decision maker, people err by deploying sacred values more often than they should, especially when it comes to sociopolitical issues. As a result, we oversimplify, grow disgusted and angry, and act in ways that contribute to social polarization.

Drawing on historical...

Do any of us really care about truth when it comes to politics? Should we? In a world of big lies, denialism, and conspiracy theories, democracies are experiencing two interlocked crises: a loss of confidence in democracy itself and the growing sense among many that politics is only about power—not truth.

In his new book, Michael Patrick Lynch argues that truth not only can—but must—matter in politics. He shows why truth is an essential democratic value—a value we need to sustain our democratic way of life—and how it can be strengthened.

When award-winning science writer Amy Alkon was blindsided by her first hot flash, it kicked off a cascade of symptoms—drenching night sweats, insomnia, and a rage she couldn't explain. But what shocked her more was how little real science her doctor had to offer.

In this episode, Alkon shares what she uncovered in her deep dive into the research on menopause and perimenopause—the critical yet often neglected years leading up to menopause when millions of women are misdiagnosed, dismissed, or simply told to "wait it out." Drawing from her new book Going Menopostal, she explains why...

What began as a call for justice has, in many cases, become an engine of conformity. In this searching conversation, Andrew Doyle (author, satirist, and cultural critic) joins Michael Shermer to unpack the trajectory of the woke movement: from its roots in anti-bigotry and awareness to its current entanglement with censorship, identitarian dogma, and ideological rigidity.

Drawing on his new book, The End of Woke Doyle traces the intellectual history of contemporary activism, explores the authoritarian impulses emerging on both the left and the right, and makes the case for a return to classical liberalism as a...

Since the dawn of the Industrial Revolution, capitalism has unleashed unimaginable growth in opportunity and prosperity. And yet, at key points in American history, economic disruption has led to a greater role for government, ostensibly to protect against capitalism's excesses. Today, government regulates, mandates, subsidizes and controls a growing share of the American economy.

Today on the show, retired U.S. Senator Phil Gramm, one of America's premier public policy advocates, and noted economist Donald J. Boudreaux look at the seven events and issues in American history that define, for most Americans, the role of government and...

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all?

Cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms.

Incorporating insights from Afshordi's cutting-edge research and Halper's original interviews with scientists like Stephen Hawking, Roger Penrose, and Alan Guth, Afshordi and Halper compare these models for the origin of our origins, showing...

In 2010, in a small New Hampshire town, next door to a copy center and framing shop, a ghost lab opened. The Kitt Research Initiative's mission was to use the scientific method to document the existence of spirits. Founder Andy Kitt was known as a straight-shooter; he was unafraid—perhaps eager—to offend other paranormal investigators by exposing the fraudulence of their less advanced techniques. But when KRI started to lose money, Kitt began to seek funding from the paranormal community, attracting flocks of psychics, alien abductees, witches, mediums, ghost hunters, UFOlogists, cryptozoologists and warlocks from all over New England, and...

This is the inside story of the CIA's secret mind control project, MKULTRA, using never-before-seen testimony from the perpetrators themselves.

Sidney Gottlieb was the CIA's most cunning chemist. As head of the infamous MKULTRA project, he oversaw an assortment of dangerous―even deadly―experiments. Among them: dosing unwitting strangers with mind-bending drugs, torturing mental patients through sensory deprivation, and steering the movements of animals via electrodes implanted into their brains. His goal was to develop methods of mind control that could turn someone into a real-life "Manchurian candidate."

In conjunction with MKULTRA, Gottlieb also plotted the...

In this eye-opening episode, Michael Shermer chats with evolutionist Telmo Pievani about the surprising coexistence—and hybridization—of Neanderthals and Homo sapiens.

They discuss recent scientific discoveries, the evolving understanding of race and biology, and the crucial role of serendipity in advancing scientific knowledge.

This episode offers a nuanced perspective on how unexpected findings continue to reshape our understanding of human origins and the scientific process itself.

Telmo Pievani is Full Professor in the Department of Biology at the University of Padua, where he covers the first Italian chair of Philosophy of Biological Scie...

Amid rising concerns about AI, inequality, trade wars, and globalization, New Yorker staff writer and Pulitzer Prize finalist John Cassidy takes a bold approach: he tells the story of capitalism through its most influential critics.

From the Luddites and early communists to the Wages for Housework movement and modern degrowth advocates, Cassidy's global narrative features both iconic thinkers—Smith, Marx, Keynes—and lesser-known voices like Flora Tristan, J.C. Kumarappa, and Samir Amin.

John Cassidy has been a staff writer at The New Yorker since 1995. He writes a regular column, The Financial Page. He holds degr...

Is it really possible to change your entire personality in a year? An award-winning journalist experiments with her own personality to find out—and reveals the science behind lasting change.

Research shows that you can alter your personality traits by behaving in ways that align with the kind of person you'd like to be—a process that can make you happier, healthier, and more successful. Olga embarked on an "experiment" to see whether it's possible to go from dwelling in dread to radiating joy. For one year, she clicked "yes" on a bucket list of new experiences—from m...

The ways that statisticians and governments measure the economy were developed in the 1940s, when the urgent economic problems were entirely different from those of today. Diane Coyle argues that the framework underpinning today's economic statistics is so outdated that it functions as a distorting lens, or even a set of blinkers. When policymakers rely on such an antiquated conceptual tool, how can they measure, understand, and respond with any precision to what is happening in today's digital economy?

Coyle argues that to understand the current economy, we need different data collected in a different framework of...

David Zweig's new book An Abundance of Caution (MIT Press) is an account of the decision-making process behind the extended closures of public schools during the pandemic. In fascinating and meticulously reported detail, Zweig shows how some of the most trusted members of society—from Pulitzer Prize-winning journalists to eminent health officials—repeatedly made fundamental errors in their assessment and presentation of evidence.

By fall 2020, many students in Europe were already back in classrooms—and so were their peers in private schools in America and in public schools across mostly "red" states and districts. Yet millions of other...

It's tempting to see ourselves as damaged or powerless—defined by past traumas, overwhelming emotions, and daily struggles. But is that really the most helpful way to understand ourselves? Does seeing ourselves as victims lead to growth?

Psychologist and author Scott Barry Kaufman joins us to examine how popular narratives around sensitivity, self-esteem, and emotional regulation may be holding us back. He unpacks the psychological costs of coddling (vs. empowerment), the rise of risk aversion, and how modern parenting, education, and therapy shape our sense of self.

With insight, empathy, and humor, Kaufman offers a ti...

Why do ordinary people carry out extraordinary harm when simply told to do so? From the Holocaust to the genocides in Rwanda, Bosnia, and Cambodia, history shows how obedience to authority can lead to unimaginable acts. But what's happening in the brain when we follow orders—even ones that conflict with our morals?

In this episode, we speak with neuroscientist Emilie Caspar, whose groundbreaking research explores how authority influences cognition and behavior. Drawing from real-life accounts of genocide perpetrators and cutting-edge neuroscience, Caspar reveals how obedience can short-circuit independent decision-making—often without us realizing it.

Albert Einstein remains renowned around the world for revolutionizing our understanding of the cosmos, but very few realize that the celebrated scientist had a deep spiritual side. Einstein believed that one wondrous force was woven through all things everywhere—and this sense of the pervasive sacred influenced every aspect of his existence, from his marvelous science to his passionate pacifism.

Outside of the academics and activists whose ideology came to dominate the West in the second decade of the twenty-first century, arguably no group influenced public discourse as much as the Intellectual Dark Web.

Challenging the intellectual and cultural orthodoxies that engulfed universities, the media, and big tech, this group—a loose collective of politically diverse intellectuals, commentators, and scholars critical of political correctness, identity politics, and cancel culture—relied on alternative platforms like podcasts, digital magazines, and YouTube to promote free speech, universal rights, and individual liberty.

While the term is most commonly identified with...

In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence.

Matt Ridley revisits Darwin's revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution.

Ridley also explores the scientific research into the evolution of bright colors, exotic ornaments, and elaborate displays in birds around the world. Charles Darwin thought the purpose of such displays was to "...

What happens to American democracy if Christianity is no longer able, or no longer willing, to perform the functions on which our constitutional order depends? Jonathan Rauch—a lifelong atheist—reckons candidly with both the shortcomings of secularism and the corrosion of Christianity.

Just as surgeons once believed pain was good for their patients, some argue today that death brings meaning to life. But given humans rarely live beyond a century (while certain whales can thrive for over two hundred years) it's hard not to see our biological limits as profoundly unfair. No wonder then that most people nearing death wish they still had more time.

Yet, with ever-advancing science, will the ends of our lives always loom so close?

In this episode, Kurt Gray offers a groundbreaking perspective on the moral mind, challenging the assumption that liberals and conservatives have radically different moral foundations.

Drawing on the latest science, he reveals that everyone's moral judgments stem from feelings of vulnerability to harm. We all care about protecting ourselves and others, but conflict arises when we perceive harm differently. Gray explores how moral outrage is triggered when we disagree about who the "real" victim is, whether in political debates, personal conflicts, or even everyday situations.

It's clear states, borders, and countries constantly evolve. But how do countries form? And what does it take to start a new one?

In the U.S. alone, more than $400 billion are donated to charity each year—equivalent to two percent of American GDP. This generosity is wonderful, but these gifts don't do nearly as much good as they could. In recent years, researchers have started studying the effectiveness of different charities, just as investors study the effectiveness of different companies. These researchers ask questions like: How much money does it cost for this charity to save someone's life? The answers are stunning. Charity experts estimate that the most effective charities are about 100 times more effective than typical charities. For example, you ca...

In this special solo episode, Michael Shermer reflects on the 2024 election.

In 2023, 107,543 Americans died from an overdose—over 75 thousand of those overdosed from fentanyl. This is almost double the number of people who died in car accidents or from gun homicides that year.

Fentanyl has been cut into heroin for years, but now is often mixed into meth and cocaine, fueling rising death counts for those drugs, a troubling development, considering that Americans are much more likely to try meth and cocaine than heroin.

In Canada, the numbers are similarly astronomical, and fentanyl deaths have marched upward in Australia and many European countries as well. Ten ye...
