In this engaging conversation on the nature of science, Dr. McIntyre and Dr. Shermer get deep into the weeds of where to draw the line between science and pseudoscience. It may seem obvious when you see it (like Justice Potter’s definition of pornography — “I know it when I see it”), from a philosophical perspective it isn’t at all easy to articulate a formula for science that perfectly weeds out all incorrect or fraudulent scientific claims while still retaining true scientific claims. It really comes down to what Dr. McIntyre describes as a “scientific attitude” in an emphasis on evidence and scientists’ willingness to change theories on the basis of new evidence. For example, claims that climate change isn’t settled science, that evolution is “only a theory,” and that scientists are conspiring to keep the truth about vaccines from the public are staples of some politicians’ rhetorical repertoire. In this podcast, and in more detail in his book, McIntyre provides listeners and readers with answers to these

When will the world end? How likely is it that intelligent extraterrestrial life exists? Are we living in a simulation like the Matrix? Is our universe but one in a multiverse? How does Warren Buffett continue to beat the stock market? How much longer will your romance last? In this wide ranging conversation with science writer William Poundstone, answers to these questions, and more, will be provided … or at least considered in the framework of Bayesian analysis. In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes’ formula has become a linchpin of the digital economy. But here’s where things get really interesting: Bayes’ theorem can also be used to lay odds on the existence of extraterrestrial intelligence; on whether we live in a Matrix-

On this July 16th, the 50th anniversary of Apollo 11, Michael Shermer speaks with veteran space reporter Charles Fishman who has been writing about NASA and the space program for more than 30 years. In One Giant Leap he delivers an all-new take on the race to the Moon that puts Apollo into a new perspective in American history. Yes, the Apollo astronauts are the well-known and well-deserved public heroes of the race to the Moon. But the astronauts didn’t make the trip possible. It took 410,000 people to make the moon landings achievable. Every hour of spaceflight for Apollo required a million hours of work by scientists, engineers and factory workers on the ground — the equivalent of 10 lifetimes of work back on Earth. Fishman tells the story of the men and women who did the work to get the astronauts, and the country, to the Moon and back. Fishman and Shermer discuss: When President John F. Kennedy rallied the nation to go to the Moon in 1961, the task was impossible. None of the technology or techniques ex

From a physician and post-traumatic stress disorder specialist comes a nuanced cartography of PTSD, a widely misunderstood yet crushing condition that afflicts millions of Americans. The Unspeakable Mind is the definitive guide for a trauma-burdened age. With profound empathy and meticulous research, Shaili Jain, M.D. — a practicing psychiatrist and PTSD specialist at one of America’s top VA hospitals, trauma scientist at the National Center for PTSD, and a Stanford Professor — shines a long-overdue light on the PTSD epidemic affecting today’s fractured world. Post-Traumatic Stress Disorder goes far beyond the horrors of war and is an inescapable part of all our lives. At any given moment, more than six million Americans are suffering with PTSD. Dr. Jain’s groundbreaking work demonstrates the ways this disorder cuts to the heart of life, interfering with one’s capacity to love, create, and work — incapacity brought on by a complex interplay between biology, genetics, and environment. Beyond the struggles of i

In this important new book, The Founding Myth: Why Christian Nationalism is Un-American, constitutional attorney and scholar at the Freedom from Religion Foundation (FFRF), Andrew L. Seidel, begins by explaining what apparently religious language is doing in the Declaration of Independence. Does this prove that America was founded on Judeo-Christian principles? Are the Ten Commandments the basis for American law? What, exactly, was the role of religion in America’s founding? Christian nationalists assert that our nation was founded on Judeo-Christian principles, and advocate an agenda based on this popular historical claim. But is this belief true? The Founding Myth answers the question once and for all. Seidel builds his case point by point, comparing the Ten Commandments to the Constitution and contrasting biblical doctrine with America’s founding philosophy, showing that the Bible contradicts the Declaration of Independence’s central tenets. Thoroughly researched, this persuasively argued and fascinating b

In this dialogue, visionary astronautical engineer Robert Zubrin lays out the plans for how humans can become a space faring, multi-planetary civilization, starting with the competing entrepreneurs like Elon Musk and Jeff Bezos who are creating a revolution in spaceflight that promises to transform the near future. Fueled by the combined expertise of the old aerospace industry and the talents of Silicon Valley entrepreneurs, spaceflight is becoming cheaper. The new generation of space explorers has already achieved a major breakthrough by creating reusable rockets. Zubrin foresees more rapid innovation, including global travel from any point on Earth to another in an hour or less; orbital hotels; moon bases with incredible space observatories; human settlements on Mars, the asteroids, and the moons of the outer planets; and then, breaking all limits, pushing onward to the stars. Zubrin shows how projects that sound like science fiction can actually become reality. But beyond the how, he makes an even more com

In this live podcast event hosted by the Santa Barbara Science Salon in conjunction with the Skeptics Society and the Unitarian Society, co-hosted by Dr. Whitney Detar, Dr. Shermer reflects on the question “What is Truth?” in the context of his lifelong search to understand why people believe weird things. What is a weird thing and how do we know what is true? This is what is known as the demarcation problem, and Dr. Shermer provides numerous examples of the difficulty of drawing a clear demarcating line between science and pseudoscience. Sometimes it’s obvious, sometimes it’s not. Michael Shermer in Santa Barbara 2019 (photo by Robert Bernstein) Science, Dr. Shermer begins, is “A set of methods designed to describe and interpret observed or inferred phenomenon, past or present, aimed at building a testable body of knowledge open to rejection or confirmation.” That is, it is “A method to explain the world that is testable and open to change.” Through the scientific method we aim for objectivity: the basing

In this wide-ranging conversation Science Salon host Dr. Michael Shermer speaks with cosmologist and inventor of the BICEP (Background Imaging of Cosmic Extragalactic Polarization) experiment Dr. Brian Keating about the following topics: how he almost won the Nobel Prize for his research that confirmed the inflationary model of the Big Bang the problems with the Nobel Prize as it is currently structured, such as its limitation to only three people (when modern experiments are typically directed by a great many more); that it can’t be awarded posthumously (thereby neglecting people like Amos Tversky, who did as much work as his Nobel Prize-winning collaborator Daniel Kahneman); its neglect of many women scientists as deserving of the prize as their male counterparts, and especially how it distorts incentives to collaborate in science his upbringing and what inspired him to probe the deepest questions about the nature of the cosmos and reality what it’s like conducting research in the harsh conditions at the S

An eminent psychologist offers a major new theory of human cognition: movement, not language, is the foundation of thought. When we try to think about how we think, we can’t help but think of words. Indeed, some have called language the stuff of thought. But pictures are remembered far better than words, and describing faces, scenes, and events defies words. Anytime you take a shortcut or play chess or basketball or rearrange your furniture in your mind, you’ve done something remarkable: abstract thinking without words. In Mind in Motion, psychologist Barbara Tversky shows that spatial cognition isn’t just a peripheral aspect of thought, but its very foundation, enabling us to draw meaning from our bodies and their actions in the world. Our actions in real space get turned into mental actions on thought, often spouting spontaneously from our bodies as gestures. Spatial thinking underlies creating and using maps, assembling furniture, devising football strategies, designing airports, understanding the flow of

Dr. Michael Ruse is the Lucyle T. Werkmeister Professor of Philosophy, and Director of the Program in the History and Philosophy of Science, at Florida State University. He has written or edited more than 50 books. His new book is “A Meaning to Life,” which we discuss on the show, as well as: Dr. Ruse’s early life growing up as a Quaker in England and how this influenced his thinking about religion why he is a bulldog against creationism but has a soft spot in his heart for religion why we should not read religious texts literally, but allegorically, and when we do there are great truths to be found, just as there is in great literature his beef with the New Atheists like Richard Dawkins and Daniel Dennett how Darwinism is a religion Darwinian existentialism how a naturalist can still find morals, values, and meaning in life through the laws of nature, particularly human and social nature what’s wrong with academia today, and what advice he would give to someone asking how to lead a meaningful life.

In recent years atheism has become ever more visible, acceptable, and influential. Atheist apologists have become increasingly vociferous and confident in their claims: that a morality requiring benevolence towards all and universal human rights need not be grounded in religion; that modern science disproves the existence of God; and that there is nothing innately religious about human beings. In Atheist Overreach, Christian Smith takes a look at the evidence and arguments, and explains why we ought to be skeptical of these atheists' claims about morality, science, and human nature. He does not argue that atheism is necessarily wrong, but rather that its advocates are advancing crucial claims that are neither rationally defensible nor realistic. Their committed worldview feeds unhelpful arguments and contributes to the increasing polarization of today's political landscape. Everyone involved in the theism-atheism debates, in shared moral reflection, and in the public consumption of the findings of science sho

Philosophers have argued about the nature and the very existence of free will for centuries. Today, many scientists and scientifically minded commentators are skeptical that it exists, especially when it is understood to require the ability to choose between alternative possibilities. If the laws of physics govern everything that happens, they argue, then how can our choices be free? Believers in free will must be misled by habit, sentiment, or religious doctrine. Why Free Will is Real defies scientific orthodoxy and presents a bold new defense of free will in the same naturalistic terms that are usually deployed against it. Unlike those who defend free will by giving up the idea that it requires alternative possibilities to choose from, Christian List retains this idea as central, resisting the tendency to defend free will by watering it down. He concedes that free will and its prerequisites—intentional agency, alternative possibilities, and causal control over our actions—cannot be found among the fundament

For this special edition of the Science Salon Podcast Dr. Shermer took a camera crew to Jared Diamond’s home in Los Angeles for an especially intimate portrait of the man and his theories. You won’t want to miss this conversation, one of the best we’ve yet recorded, with one of the most interesting minds of our time, perhaps of all time. In his earlier bestsellers Guns, Germs and Steel and Collapse, Jared Diamond transformed our understanding of what makes civilizations rise and fall. Now, in the final book in this monumental trilogy, he reveals how successful nations recover from crisis through selective change — a coping mechanism more commonly associated with personal trauma. In a dazzling comparative study, Diamond shows us how seven countries have survived defining upheavals in the recent past — from US Commodore Perry’s arrival in Japan to the Soviet invasion of Finland to Pinochet’s regime in Chile — through a process of painful self-appraisal and adaptation, and he identifies patterns in the way that

In this fascinating conversation with the evolutionary anthropologist Michael Tomasello, the Max Planck Institute scientist presents his new theory of how humans became such a distinctive species. Other theories focus on evolution. Here, Tomasello proposes a complementary theory of human uniqueness, focused on development. His data-driven model explains how those things that make us most human are constructed during the first years of a child’s life. Tomasello assembles nearly three decades of experimental work with chimpanzees, bonobos, and human children to propose a new framework for psychological growth between birth and seven years of age. He identifies eight pathways that starkly differentiate humans from their closest primate relatives: social cognition, communication, cultural learning, cooperative thinking, collaboration, prosociality, social norms, and moral identity. In each of these, great apes possess rudimentary abilities. But then, Tomasello argues, the maturation of humans’ evolved capacities

Through the lens of evolutionary science, Dr. Garcia offers a novel perspective on why we hold our political ideas, and why they are so often in conflict. Drawing on examples from across the animal kingdom, Garcia reveals how even the most complex political processes can be influenced by our basic drives to survive and reproduce—including the policies we back, whether we are liberal or conservative, and whether we are inspired or repelled by the words of a president. Garcia explains how our political orientations derive from an ancestral history of violent male competition, surprisingly influencing how we respond to issues as wide-ranging as affirmative action, women’s rights, social welfare, abortion, foreign policy, and even global warming. Critically, Garcia shows us how our instinctive political tribalism can keep us from achieving stable, functioning societies, and offers solutions for rising above our ancestral past. Dr. Garcia and Dr. Shermer also discuss: Trump and other political leaders through the

In this AMA special Dr. Shermer conducts a postmortem on his debate with the evangelical Christian theologian Luuk van de Weghe, with Windmill Ministries, before an audience of about 400 people, the vast majority of which were evangelicals. Dr. Shermer argues in the affirmative to the debate proposition that the miracles of Jesus are unbelievable. In this postmortem Dr. Shermer elaborates on his notes for the debate, suggesting ways to think about miracles from a scientific or naturalistic perspective. The debate took place on March 30, 2019 in Sequim, Washington, and was moderated by Justin Brierley.

In this riveting conversation, Dr. Shermer speaks with Dr. Mark Moffett, biologist (Ph.D. Harvard, under E. O. Wilson), wildlife photographer for National Geographic, cave explorer, and world traveler about his new book, The Human Swarm: How Our Societies Arise, Thrive, and Fall, on the nature of societies from a biologist’s perspective. Scientists routinely explain that humans rule the planet because of our intelligence, tools, or language, but as Moffett argues, our biggest asset, surprisingly overlooked to date, is our ability to be comfortable around strangers. We can walk into a cafe or stadium full of unfamiliar people without thinking twice, but a chimpanzee, wolf or lion, encountering strangers could be attacked and perhaps killed. This ability—not IQ—has allowed humans to swarm over the world in vast nations. If we want to compare ourselves to the rest of the animal kingdom in order to define what makes our societies unique, Moffett argues that it’s time we look at ants. Making their way across the A

We Homo sapiens can be the nicest of species and also the nastiest. What occurred during human evolution to account for this paradox? What are the two kinds of aggression that primates are prone to, and why did each evolve separately? How does the intensity of violence among humans compare with the aggressive behavior of other primates? How did humans domesticate themselves? And how were the acquisition of language and the practice of capital punishment determining factors in the rise of culture and civilization? Authoritative, provocative, and engaging, The Goodness Paradox offers a startlingly original theory of how, in the last 250 million years, humankind became an increasingly peaceful species in daily interactions even as its capacity for coolly planned and devastating violence remains undiminished. In tracing the evolutionary histories of reactive and proactive aggression, biological anthropologist Richard Wrangham forcefully and persuasively argues for the necessity of social tolerance and the control

In this exceptionally important conversation Dr. Shermer discusses at length the background to and research of Dr. Nicholas Christakis, a physician and evolutionary sociologist famous for his study of social networks in humans and other animals. Drawing on advances in social science, evolutionary biology, genetics, neuroscience, and network science, Blueprint shows how and why evolution has placed us on a humane path—and how we are united by our common humanity. For too long, scientists have focused on the dark side of our biological heritage: our capacity for aggression, cruelty, prejudice, and self-interest. But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all our inventions—our tools, farms, machines, cities, nations—we carry with us innate proclivities to make a good society. In Blueprint, Nicholas A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but

In this pathbreaking book, New York Times bestselling author Cass Sunstein asks us to rethink freedom. He shows that freedom of choice isn’t nearly enough. To be free, we must also be able to navigate life. People often need something like a GPS device to help them get where they want to go — whether the issue involves health, money, jobs, children, or relationships. In both rich and poor countries, citizens often have no idea how to get to their desired destination. That is why they are unfree. People also face serious problems of self-control, as many of them make decisions today that can make their lives worse tomorrow. And in some cases, we would be just as happy with other choices, whether a different partner, career, or place to live — which raises the difficult question of which outcome best promotes our well-being. Accessible and lively, and drawing on perspectives from the humanities, religion, and the arts, as well as social science and the law, On Freedom explores a crucial dimension of the human c
