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.

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, evolution, and life itself. Along the way, myths hardened around personalities, credit, and rivalries, especially in the case of Rosalind Franklin, whose role has been both misunderstood and oversimplified.

The conversation also traces Crick’s later turn away from molecular biology toward the problem that fascinated him from the beginning: consciousness. From visual perception to the search for neural correlates of experience, his ambition was to push back against mystical explanations and insist that even the most elusive aspects of the mind belonged to the material world.

Matthew Cobb is a professor in the School of Biological Sciences at the University of Manchester. He is the author of numerous works of science and history. His new book is Crick: A Mind in Motion, a biography of the legendary scientist Francis Crick, co-discoverer of the structure of DNA.

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 end.

Daryl Davis earned his Bachelor of Music degree from Howard University and an Honorary Doctorate in Humane Letters from Post University. He is the author of Klan-Destine Relationships and the subject of the multi-award-winning documentary Accidental Courtesy, which chronicles his work in race reconciliation. A lifelong musician, he has performed with Chuck Berry and President Bill Clinton, and as an actor appeared in HBO’s The Wire.

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 what happens to liberal societies when some questions can no longer be asked, nd whether open inquiry can still be defended without abandoning concern for fairness and dignity

Eric Kaufmann is a professor of politics and Director of the Centre for Heterodox Social Science at the University of Buckingham. He has written for The New York Times, Wall Street Journal, Times of London, Newsweek, National Review, New Statesman, Financial Times, and other outlets. His new book is The Third Awokening.

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 has been limited not by biology, but by data—how much information we can actually read from the brain, and how fast. He describes how patients who can no longer speak may soon communicate fluently using only brain signals, why invasive implants can sometimes be safer than long-term drug treatments, and what it takes to bring a brain implant through FDA approval and into the clinic.

The conversation also touches on the larger questions raised by this technology, including autonomy, consciousness, and what happens when the boundary between brain and machine begins to blur.

Matt Angle is the Founder and CEO of Paradromics, a neurotechnology leader developing the world’s most advanced and clinically viable brain-computer interface (BCI) platform—bridging human thought and digital capability. Paradromics’ BCI platform records brain activity with unmatched precision, capturing data at the level of individual neurons. This advanced technology enables the decoding of vast amounts of brain data, opening the door to next-generation treatments for paralysis, chronic pain, addiction, mental health conditions, and more. With the power of AI, this platform has the potential to radically shift how healthcare providers approach some of the most challenging medical conditions.

Angle earned his PhD in Neuroscience from the University of Heidelberg, followed by postdoctoral research at Stanford University. Paradromics engineered its first clinical product, the Connexus® BCI, received two FDA Breakthrough Device Designations, and performed the first-in-human neural recording in May 2025. The company is now preparing to launch a clinical trial in early 2026, pending regulatory approval.

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 science fiction in fueling public belief.

The episode also connects this forgotten moment to present-day debates about UFOs, alien megastructures, and the search for extraterrestrial intelligence, raising broader questions about how scientific ideas spread and why some claims capture the public imagination.

David Baron is an award-winning journalist, broadcaster, and author. A former science correspondent for NPR, he has also written for The New York Times, The Washington Post, The Wall Street Journal, The Los Angeles Times, Scientific American, and other publications. David recently served as the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology, Exploration, and Scientific Innovation. His new book is The Martians: The True Story of an Alien Craze that Captured Turn-of-the-Century America.

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 Edwards teaches history, English, and mathematics at a public school in the Midwest. He is a frequent contributor to Skeptic magazine and the author of Thought Experiments: History and Applications for Education, Beyond Obsolete: How to Upgrade Classroom Practice and School Structure, Femocracy: How Educators Can Teach Democratic Ideals and Feminism, and most recently of The New Order: How AI Rewrites the Narrative of Science. His background is in world history.
