“Those who can make you believe absurdities, can make you commit atrocities.” — Voltaire In this monologue commentary on the events of January 6, 2021, Dr. Shermer applies causal inference theory to Trump’s speech that morning, the violent assault on the Capitol that followed, the banning of Trump off social media platforms like Twitter and Facebook, the fears on the Right of social media censoriousness on the Left, the breaking up of big tech social media companies, and related topics, including what it means to “believe” a conspiracy theory.

“Nothing about the biology of exercise makes sense except in the light of evolution, and nothing about exercise as a behavior makes sense except in the light of anthropology.” In this myth-busting book, Daniel Lieberman, professor of human evolutionary biology at Harvard University and a pioneering researcher on the evolution of human physical activity, tells the story of how we never evolved to exercise — to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, Lieberman recounts how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion. As our increasingly sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases such as diabetes, Lieberman argues that to become more active we need to do more than medicalize and commodify exercise. Shermer and Lieberman also discuss: evolutionary and anthropological perspectives on physical activity, why we

In this special episode of the Science Salon podcast, the last of 2020, Dr. Michael Shermer offers some reflections on 2020, starting with race and the Black Lives Movement, putting it into perspective from other books he read this year, along with podcast guests who appeared in 2020, such as Shelby Steele. Dr. Shermer recently read Isabel Wilkerson’s book Caste and Ibram X. Kendi’s book How to Be an Anti-Racist, and offers some thoughts on them, along with other issues competing for our attention of ills troubling society, including class conflicts, income inequality, lack of education, anti-Semitism, far-left illiberalism, and religious indoctrination. Everyone thinks that their particular focus is the only one that matters, but broad reading can put each into perspective. Dr. Shermer then reads his essay of the podcast title, originally published in The American Scholar and expanded on here and in an upcoming issue of Skeptic magazine.

In this special episode of the Science Salon podcast Dr. Michael Shermer reflects on the recent resurrection of Jordan Peterson, the resurgent criticism of him and why so many people attack him, why similar such unwarranted attacks have been made against public intellectuals like Richard Dawkins and Sam Harris today, and of Stephen Jay Gould and Carl Sagan in the past. Dr. Shermer then reads his essay of this title that was originally published in Skepticmagazine 23.3 (2018), and on skeptic.com, and is reprinted in his essay collection Giving the Devil His Due.

In a conversation based on the book Threats: Intimidation and its Discontents, Shermer and Barash discuss: 2020 as the most momentous year of the past half century, judging historical figures based on modern morals (e.g., race and slavery), whether humans are naturally gullible or skeptical, the evolutionary logic of deterrence, how animals deal with threats, how humans deal with threats, game theory of deterring threats, nuclear deterrence (Mutual Assured Destruction) as a threat strategy, the motives behind nuking Hiroshima and Nagasaki, the U.S. arms race against the U.S.S.R., the arms race within the U.S. between the Army, Navy, and Airforce, close calls with nuclear weapons and why this is not a sustainable strategy, how to deal with threats like Iran, China, Russia, and North Korea, Trump and what he did right with regard to North Korea. David P. Barash is an evolutionary biologist and Professor Emeritus of Psychology at the University of Washington. He has written more than 280 peer-reviewed articles

Shermer and Prothero discuss: flat earth theories and how we know the earth is round, hollow earth theories and how we know it’s not hollow, the return of Ptolemy and an earth-centered solar system model (and how we know it’s wrong), how science deals with anomalies, fringe claims, and challenges to the orthodoxy, whether humans were in the San Diego area 130,000 years ago, how consensus is achieved in science (and the messy road to get there), from Newton to Einstein and what ultimately determines if a theory is true or not, flood myths and what causes such stories to arise in some cultures but not others, catastrophism vs. uniformitarianism in geology, the age of the earth and how geologists determined it, the myth of Atlantis and what Plato really intended with his account, biblical accounts of the world and how we should read the book as literature, not science, how science won the evolution-creation wars, science denial and how to deal with it, and the real-world consequences of denying science. Dr. Do

In this wide ranging conversation focused on Greg Lukianoff’s co-authored (with Jonathan Haidt) book The Coddling of the American Mind, and his new documentary film Mighty Ira: A Civil Liberties Story, about the free speech champion Ira Glassner, who headed the ACLU for decades, he and Shermer discuss: the state of free speech today, how coddled today’s students are, the data on rates of depression and anxiety in students today, possible causes of the coddling of the American mind: social media, screen time, culture of safetyism, culture of victimhood, helicopter parenting, the decline of unsupervised, child-directed play, cancel culture and its effect on self-censorship and silencing speech, current rates of deplatforming and canceling in academia, the polarization of politics, when self-censorship is healthy, default to truth theory vs. default to skepticism theory, How gullible are we, really? how to combat the negative influencers on social media, a brief history of free speech in the 20th and 21th centu

Why are so many humans religious? Why do we daydream, imagine, and hope? Philosophers, theologians, social scientists, and historians have offered explanations for centuries, but their accounts often ignore or even avoid human evolution. Evolutionary scientists answer with proposals for why ritual, religion, and faith make sense as adaptations to past challenges or as by-products of our hyper-complex cognitive capacities. But what if the focus on religion is too narrow? Renowned anthropologist Agustín Fuentes argues that the capacity to be religious is actually a small part of a larger and deeper human capacity to believe. Why believe in religion, economies, love? Fuentes employs evolutionary, neurobiological, and anthropological evidence to argue that belief — the ability to commit passionately and wholeheartedly to an idea — is central to the human way of being in the world. The premise of the book is that believing is our ability to draw on our range of cognitive and social resources, our histories and exp

Apollo’s Arrow offers a riveting account of the impact of the coronavirus pandemic as it swept through American society in 2020, and of how the recovery will unfold in the coming years. Drawing on momentous (yet dimly remembered) historical epidemics, contemporary analyses, and cutting-edge research from a range of scientific disciplines, bestselling author, physician, sociologist, and public health expert Nicholas A. Christakis explores what it means to live in a time of plague — an experience that is paradoxically uncommon to the vast majority of humans who are alive, yet deeply fundamental to our species. Featuring new, provocative arguments and vivid examples ranging across medicine, history, sociology, epidemiology, data science, and genetics, Apollo’s Arrow envisions what happens when the great force of a deadly germ meets the enduring reality of our evolved social nature. Shermer and Christakis discuss: the replication crisis in social science and medicine, determining causality in science and medicin

Understanding how brains produce consciousness is one of the great scientific challenges of our age. Some philosophers argue that consciousness is something “extra,” beyond the physical workings of the brain. Others think that if we persist in our standard scientific methods, our questions about consciousness will eventually be answered. And some even suggest that the mystery is so deep, it will never be solved. Decades have been spent trying to explain consciousness from within our current scientific paradigm, but little progress has been made. Now, Philip Goff offers an exciting alternative that could pave the way forward. Rooted in an analysis of the philosophical underpinnings of modern science and based on the early twentieth-century work of Arthur Eddington and Bertrand Russell, Goff makes the case for panpsychism, a theory which posits that consciousness is not confined to biological entities but is a fundamental feature of all physical matter — from subatomic particles to the human brain. In Galileo’s

The provocative thesis of Break It Up is simple: The United States has never lived up to its name—and never will. The disunionist impulse may have found its greatest expression in the Civil War, but as Break It Up shows, the seduction of secession wasn’t limited to the South or the 19thcentury. It was there at our founding and has never gone away. Investigative journalist Richard Kreitner takes readers on a revolutionary journey through American history, revealing the power and persistence of disunion movements in every era and region. Each New England town after Plymouth was a secession from another; the 13 colonies viewed their Union as a means to the end of securing independence, not an end in itself; George Washington feared separatism west of the Alleghenies; Aaron Burr schemed to set up a new empire; John Quincy Adams brought a Massachusetts town’s petition for dissolving the United States to the floor of Congress; and abolitionist William Lloyd Garrison denounced the Constitution as a pro-slavery pact

The common narrative of Neanderthals is that they were a group of dullard losers whose extinction 40,000 years ago was due to smarter competition and a little of interbreeding with our own forebears. Likening someone to a Neanderthal was and, most likely, still is a top-rate anthropological insult. But, in the past few decades, Neanderthal finds have greatly contradicted our perception of the species. In Kindred, Rebecca Wragg Sykes combs through the avalanche of scientific discoveries of the species and uses her experience at the cutting-edge of Paleolithic research to share our new understanding of Neanderthals, shoving aside cliches of rag-clad brutes in an icy wasteland. She reveals them to be curious, clever connoisseurs of their world, technologically inventive and ecologically adaptable. They ranged across vast tracts of tundra and steppe, but also stalked in dappled forests and waded in the Mediterranean Sea. Above all, they were successful survivors for more than 300,000 years, during times of massiv

This classic lecture on skepticism was given by James Randi on March 22, 1992 at the inaugural session of the Distinguished Science Lecture Series hosted by Michael Shermer and presented by The Skeptics Society in California (1992–2015). The transcript for this lecture appeared in Skeptic magazine 1.1 (1992). James Randi presents an amazing first-hand analysis of astonishing claims encountered in his European visit. New-found freedoms stimulate rampant pseudoscientific practices in eastern bloc nations. With wit and wonderfully illustrative examples, Randi teaches us several lessons on the scientific investigation of unusual claims. Famed magician and investigator of paranormal claims, Randi is best selling author of The Faith Healers and Flim Flam! Randi was awarded the prestigious MacArthur Grant for his investigation of faith healers.

The United States today is hopelessly polarized; the political Right and Left have hardened into rigid and deeply antagonistic camps, preventing any sort of progress. Amid the bickering and inertia, the promise of the 1960s—when we came together as a nation to fight for equality and universal justice—remains unfulfilled. As Shelby Steele reveals in Shame, the roots of this impasse can be traced back to that decade of protest, when in the act of uncovering and dismantling our national hypocrisies—racism, sexism, militarism—liberals internalized the idea that there was something inauthentic, if not evil, in the America character. Since then, liberalism has been wholly concerned with redeeming modern America from the sins of the past, and has derived its political legitimacy from the premise of a morally bankrupt America. The result has been a half-century of well-intentioned but ineffective social programs, such as Affirmative Action. Steele reveals that not only have these programs failed, but they have in alm

In this special episode of the Science Salon Podcast, Michael Shermer catches up with Douglas Murray one year after the publication of his bestselling book The Madness of Crowds, which was featured in Science Salon # 87 in October 2019. Murray’s book is now out in paperback with an Afterword update on all that has happened the past year, one of the most momentous in living memory. Shermer and Murray discuss: why he wasn’t “cancelled” after The Madness of Crowds was published and became a bestseller, what people should do if they’re cancelled, shamed, mobbed, or accused of being racist, misogynist, transphobic, or bigoted and they know they’re not, how to fight back against wokeness, political correctness, and identity politics, updates on the featured topics in The Madness of Crowds: gay, women, race, trans, J.K. Rowling and “people who menstruate” (if only there was a single word for that phrase), statues and why some people want them taken down (Lord Nelson may be next…find out why), why leftists think ev

From the day her daughter was born, science journalist Marta Zaraska fretted about what she and her family were eating. She fasted, considered adopting the keto diet, and ran a half-marathon. She bought goji berries and chia seeds and ate organic food. But then her research brought her to read countless scientific papers and to interview dozens of experts in various fields of study, including molecular biochemistry, epidemiology and neuroscience. What Marta discovered shattered her long-held beliefs about aging and longevity. A strong support network of family and friends, she learned, lowers mortality risk by about 45 percent, while exercise only lowers it by about 23 percent. Volunteering your free time lowers it by 22 percent or so, while certain health fads like turmeric haven’t been shown to help at all. These revelations led Marta Zaraska to a simple conclusion: In addition to healthy nutrition and physical activity, deepening friendships, practicing empathy and contemplating your purpose in life can im

There’s a war against truth and if we don’t win it, intellectual freedom will be a casualty. The West’s commitment to freedom, reason, and true liberalism has never been more seriously threatened than it is today by the stifling forces of political correctness. Dr. Gad Saad exposes the bad ideas—what he calls “idea pathogens”—that are killing common sense and rational debate. Incubated in our universities and spread through the tyranny of political correctness, these ideas are endangering our most basic freedoms—including freedom of thought and speech. The danger is grave, but as Dr. Saad shows, politically correct dogma is riddled with logical fallacies. We have powerful weapons to fight back with—if we have the courage to use them. A provocative guide to defending reason and intellectual freedom and a battle cry for the preservation of our fundamental rights, The Parasitic Mind will be the most controversial and talked-about book of the year. Shermer and Saad discuss: which idea pathogens are the most dang

Does the universe have a speed limit? If not, some effects could happen at the same instant as the actions that caused them — and some effects, ludicrously, might even happen before their causes. By one hundred years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. Inspired by the new physics, psychologist Carl Jung and physicist Wolfgang Pauli explored a concept called synchronicity, a weird phenomenon they thought could link events without causes. Synchronicity tells that sprawling tale of insight and creativity, and asks where these ideas — some plain crazy, and others crazy powerful — are taking the human story next. Shermer and Halpern discuss: Model-Dependent Realism, the idea from Stephen Hawking and Leonard Mlodinow that our understanding of nature depends on the model we apply to it, and that we cannot define science as an asymptot

WEIRD: Western, Educated, Industrialized, Rich, and Democratic. Unlike much of the world today, and most people who have ever lived, WEIRD people are highly individualistic, self-obsessed, control-oriented, nonconformist, and analytical. They focus on themselves — their attributes, accomplishments, and aspirations — over their relationships and social roles. How did WEIRD populations become so psychologically distinct? What role did these psychological differences play in the industrial revolution and the global expansion of Europe during the last few centuries? To answer these questions Joseph Henrich draws on anthropology, psychology, economics, and evolutionary biology. He illuminates the origins and evolution of family structures, marriage, and religion, and the profound impact these cultural transformations had on human psychology. Mapping these shifts through ancient history and late antiquity, Henrich reveals that the most fundamental institutions of kinship and marriage changed dramatically under pres

In this sweeping psychological history of human goodness — from the foundations of evolution to the modern political and social challenges humanity is now facing — psychologist Michael McCullough answers a fundamental question: How did humans, a species of self-centered apes, come to care about others?Ever since Darwin, scientists have tried to answer this question using evolutionary theory. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior. As McCullough argues, these choices weren’t enabled by an evolved moral sense, but with moral invention — driven not by evolution’s dictates but by reason. Today’s challenges — climate change, mass migration, nationalism — are some of humanity’s greatest yet. In revealing how past crises shaped the foundations of human concern, McCullough offers clues for how
