Free speech was supposed to be the great settled achievement of liberal democracy. Then came social media, cancel culture, campus speech battles, hate-speech laws, authoritarian tech control, and a new era of governments pressuring platforms from every direction. Michael Shermer speaks with free speech scholar Jacob Mchangama about why speech protections are weakening around the world—not only in dictatorships, but inside democracies. Their conversation moves from the First Amendment and January 6 to hate speech laws in Europe, Section 230, Elon Musk and X, online anonymity, social media bans for minors, and the enormous promise and danger of AI. Mchangama argues that censorship is less a left-wing or right-wing impulse than a human one: once people gain power, the urge to silence enemies becomes almost irresistible. The real test of free speech is not whether we defend ideas we like, but whether we resist using state power against speech we despise. Jacob Mchangama is the founder and executive director of The Future of Free Speech and a research professor at Vanderbilt University. His new book is The Future of Free Speech: Reversing the Global Decline of Democracy's Most Essential Freedom.

The long-promised UFO files have finally been released. In this solo commentary, Michael Shermer examines the newly declassified documents, photographs, videos, eyewitness accounts, redactions, and government claims surrounding UFOs and UAPs.

Stewart Brand has spent a lifetime thinking about tools, systems, civilization, and the long future. Best known as the creator of the Whole Earth Catalog and co-founder of the Long Now Foundation, Brand joins Michael Shermer to discuss his new book, Maintenance of Everything, a sweeping look at what it takes to keep bodies, machines, buildings, institutions, planets, and civilizations from falling apart. The conversation ranges from the hidden work of maintenance to electric vehicles, bicycles, nuclear power, AI, and even human populations. Brand makes the case that life itself is maintenance: everything alive must keep itself going, and everything humans build must be repaired, improved, updated, and cared for. Stewart Brand is the cofounder and president of The Long Now Foundation and cofounder of Global Business Network, the Hackers Conference, and the WELL. He created and edited the National Book Award-winning Whole Earth Catalog from 1968 to 1998. He was the subject of the documentary We Are As Gods (2020). He graduated from Stanford with a degree in biology and served as an infantry officer in the US Army. His new book is Maintenance of Everything.

Can memories survive death? It sounds like the kind of question skeptics usually dismiss before the conversation even starts. But Ian Stevenson was not a carnival psychic or a late-night ghost hunter. He was a respected psychiatrist at the University of Virginia who spent decades investigating children who claimed to remember previous lives, along with cases involving birthmarks, apparitions, telepathy, and other alleged evidence for life after death. In this episode, psychologist and science writer Jesse Bering talks about Stevenson's strange and fascinating career, the psychology of afterlife belief, why the mind so easily imagines consciousness continuing after death, and what to do with cases that are hard to explain but far from proven. Jesse Bering is a science writer, research psychologist, and head of the Science Communication program at the University of Otago in New Zealand. He is the author of several books, including: Why Is the Penis Shaped Like That? And Other Reflections on Being Human and Suicidal: Why We Kill Ourselves. His new book is The Incredible Afterlives of Dr. Stevenson: One Scientist's Epic Quest for Evidence of Reincarnation, Apparitions, Poltergeists, and Other Matters of the Soul.

Astrophysicist Hakeem Oluseyi has lived a life that sounds almost impossible: a childhood marked by poverty, violence, and constant upheaval; a teenage obsession with Einstein; a stint in the Navy; addiction and recovery; work as a janitor; and eventually a PhD in physics from Stanford. In this conversation, Michael Shermer and Oluseyi talk about his new book, Why Do We Exist?, and the biggest questions science can ask: what came before the Big Bang, whether the multiverse is real, why the universe seems fine-tuned for life, what dark matter and dark energy really mean, and why alien civilizations may be far rarer than we hope. Hakeem Oluseyi is a multidisciplinary astrophysicist, multi-patented inventor, award-winning author and journalist, and internationally recognized educator. His new book is Why Do We Exist?: The Nine Realms of Universe That Make You Possible.

A viral story is spreading across media: a mysterious string of scientists connected to UFOs, nuclear weapons, aerospace, and defense work have disappeared or died under suspicious circumstances. Politicians are calling it a possible national security threat. Michael Shermer takes a skeptical look.

What kind of person helps build a regime like the Third Reich? A monster? A madman? Or something far more unsettling? Michael Shermer sits down with author Jack El-Hai to talk about the true story behind Nuremberg. At the center is Dr. Douglas Kelley, the American psychiatrist assigned to evaluate the top Nazi defendants after World War II, including Hermann Göring. What he found was not comforting: many of these men were intelligent, ambitious, psychologically functional, and disturbingly normal. This conversation gets into the strange duel between Kelley and Göring, the psychological testing at Nuremberg, the limits of psychiatry, the difference between leaders and followers, and the question that still won't go away: how do power-hungry people rise and do evil, and why do so many others go along with them? Jack El-Hai is an author and journalist whose work has appeared in The Atlantic, Smithsonian, GQ, Wired, Scientific American, and Discover. His books, including The Lobotomist, The Lost Brothers, and Face in the Mirror, have been translated into twenty languages. He lectures widely on writing and medical history. His book The Nazi and the Psychiatrist was recently adapted into the feature film Nuremberg, starring Russell Crowe and Rami Malek.

What actually makes a life feel meaningful? In this conversation, Daniel Coyle joins Michael Shermer to talk about why fulfillment rarely comes from optimization, status, or trying to "win" at everything. Instead, it grows out of connection, shared effort, curiosity, and the kinds of projects that pull people out of themselves and into real community. Coyle makes the case that flourishing is not a mood and not a hack. It's a process. It happens in groups, in relationships, and in the messy work of building something with other people. Daniel Coyle is the New York Times bestselling author of The Culture Code, which was named Best Business Book of the Year by Bloomberg, BookPal, and Business Insider. Coyle has served as an advisor to many high-performing organizations, including the Navy SEALs, Microsoft, Google, and the Cleveland Guardians. His other books include The Talent Code, The Secret Race, The Little Book of Talent, and Hardball: A Season in the Projects, which was made into a movie starring Keanu Reeves. His new book is Flourish: The Art of Building Meaning, Joy, and Fulfillment.

What actually causes cognitive decline, and how much of it can we do something about? In this episode, Michael talks with neurologist and neuroscientist Dr. Majid Fotuhi about dementia, Alzheimer's, memory loss, and the everyday habits that shape brain health over time. They discuss why Alzheimer's is only part of the story, why some people remain mentally sharp into old age, and what the evidence says about exercise, sleep, diet, stress, and cognitive activity. They also cover ADHD, attention, brain training, and the difference between ordinary forgetfulness and something more serious. At the center of it all is a simple but important idea: many people think cognitive decline is just an unavoidable part of aging, when in fact there is often more room to protect brain function than most of us realize. Majid Fotuhi, MD, PhD, is an adjunct professor of Neuroscience at Johns Hopkins's Mind/Brain Institute, an adjunct professor of Psychological and Brain Sciences at George Washington University, and is the medical director of NeuroGrow Brain Fitness Center. His groundbreaking, proprietary research has been published in The Lancet, Nature, Neurology, Neuron, Proceedings of National Academy of Science, the Journal of Prevention of Alzheimer's Disease, Journal of Rehabilitation, and Journal of Alzheimer's Disease Reports, among others. His new book is The Invincible Brain: The Clinically Proven Plan to Age-Proof Your Brain and Stay Sharp for Life.

Why does religion still dominate American politics when so many other wealthy democracies secularized long ago? In this episode, Michael Shermer talks with historian Matthew Avery Sutton about the long relationship between Christianity and American power. From the Puritans to Lincoln, from the Scopes trial to the Religious Right, from slavery to same-sex marriage, this conversation tracks how religious belief has shaped the country, and how politics keeps reshaping religion in return. Matthew Avery Sutton is the Claudius O. and Mary Johnson Distinguished Professor and chair of the Department of History at Washington State University. His new book is Chosen Land: How Christianity Made America and Americans Remade Christianity.
