Michael Shermer

The Michael Shermer Show is a series of long-form conversations between Dr. Michael Shermer and leading scientists, philosophers, historians, scholars, writers and thinkers about the most important issues of our time.

The Michael Shermer Show

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.

The Myth of Human Exceptionalism: Why Humans Aren’t as Special as We Think

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 appeared in The New York Review of Books, The New Yorker, The Atlantic, Los Angeles Times, and London Review of Books, among other publications. Her new book is Murderland: Crime and Bloodlust in the Time of Serial Killers.

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 Thinking, Fast and Slow—Barry Schwartz shows how the focus on rationality, narrowly understood, fails to fully describe how we think about our decisions, much less help us make better ones.
 
Barry Schwartz is professor emeritus of psychology at Swarthmore College and visiting professor at Haas School of Business, University of California, Berkeley. His research and writing focus on the intersection of psychology and economics, particularly with regard to decision-making, intrinsic and extrinsic motivation, and the nature of human values. His books include The Paradox of Choice, Why We Work, and (as coauthor) Practical Wisdom. His new book, co-authored with the philosopher Richard Schuldenfrei, is Choose Wisely: Rationality, Ethics, and the Art of Decision-Making.

When Rationality Becomes Irrational

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 a lecturer in psychiatry at the Yale School of Medicine, a lawyer, and the founder and co-director of the Yale Collaborative for Motive Control Studies. A breakthrough scholar and expert on revenge, he first identified compulsive revenge seeking as an addiction and developed the behavioral addiction model of revenge as a public health approach for preventing and treating violence. His new book is The Science of Revenge: Understanding the World’s Deadliest Addiction—and How to Overcome It.

The Science of Revenge: Why Getting Even Feels So Good

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 for families that have a loved one involved in a range of coercive situations, including cults, gangs, domestic violence, trafficking, and violent extremism. She also served as the Director of Events for the International Cultic Studies Association (ICSA), organizing regional and international events, workshops, and conferences for those affected by the cult phenomena and psychological manipulation.

Why No One Thinks They’re in a Cult

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 gathering of free minds.” He is the author of over 25 books, incl. his latest, The Greatest American: Benjamin Franklin, The World’s Most Versatile Genius.

Was Benjamin Franklin America’s First Scientist?

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 got right, and what it all reveals about our preparedness for the next great pandemic.
 
Michael Osterholm is Regents Professor and McKnight Presidential Endowed Chair in Public Health at the University of Minnesota, where he founded and directs the Center for Infectious Disease Research and Policy (CIDRAP). An internationally renowned epidemiologist with fifty years of experience, he's led major outbreak investigations worldwide and authored over 350 papers. He served as a U.S. State Department science envoy from 2017-2019. His new book is The Big One: How We Must Prepare for Future Deadly Pandemics.

COVID-19: What We Learned (and Didn’t) About Masks, Lockdowns, and Vaccines

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 threats, sexual innuendo, and pretending not to see the elephant in the room.
 
Pinker shows how the hidden logic of common knowledge can make sense of many of life’s enigmas: financial bubbles and crashes, revolutions that come out of nowhere, the posturing and pretense of diplomacy, the eruption of social media shaming mobs and academic cancel culture, the awkwardness of a first date.
 
Steven Pinker is the Johnstone Professor of Psychology at Harvard University. He is an elected member of the National Academy of Sciences, a two-time Pulitzer Prize finalist, and one of Time’s “100 Most Influential People in the World Today.” He has won many prizes for his teaching, his research on language, cognition, and social relations, and his twelve books. His new book is When Everyone Knows That Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.

The Power of Common Knowledge: Steven Pinker on Language, Norms, and Punishment

In episode 204, Michael Shermer speaks with codirector of undergraduate studies in the Department of Human Evolutionary Biology at Harvard University, Carole Hooven, PhD about testosterone. While most people agree that sex differences in human behavior exist, they disagree about the reasons. But the science is clear: testosterone is a potent force in human society, driving the bodies and behavior of the sexes apart. But, as Hooven shows in T, it does so in concert with genes and culture to produce a vast variety of male and female behavior. And, crucially, the fact that many sex differences are grounded in biology provides no support for restrictive gender norms or patriarchal values. In understanding testosterone, we better understand ourselves and one another — and how we might build a fairer, safer society.
