The Michael Shermer Show

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 improve your lifespan. Shermer and Zaraska also discuss: diet, nutrition, and supplements: what works, what doesn’t, and what about meat? exercise: how much, what type, and when? the causal mechanisms behind how relationships and marriage effect health, how friendships and community affect longevity, how religion makes people healthier and longer lived, why we need others and why handshakes and hugs will return after COVID-19, the harmful effects of loneliness and isolation, the deleterious effects of stress, and how leading a purposeful and meaningful life leads to longevity. Marta Zaraska is a Canadian-Polish science journalist. She has written about nutrition and psychology for the Washington Post, Scientific American, The Atlantic, The Los Angeles Times, New Scientist, and several other publications. She is the author of Meathooked: The History and Science of Our 2.5-Million-Year Obsession with Meat (Basic Books, 2016), which has been translated into Japanese, Korean, simplified Chinese, Spanish and Polish, and chosen by the journal Nature as one of “the best science picks” in March 2016. Meathookedhas also been praised in The Wall Street Journal, Discover Magazine, Time, The Washington Post, Kirkus Reviews, Natural History Magazine, etc. She has also contributed a chapter to the recently published The Reducetarian Solution (TarcherPerigee, 2017) alongside Mark Bittman, Michael Shermer, and Peter Singer.

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 dangerous, the analogy between biological and ideological parasites, the origin of political correctness and how it was corrupted, identity politics and how it perpetrates bigotry, racism, and misogyny, the psychology of victimhood status (why would anyone want to be a victim?), virtue signaling and why it isn’t virtuous, why social justice is injustice, social justice warriors as sneaky fuckers, the corruption of postmodernism, which began as a form of rational skepticism, Islamophobia, diversity, inclusion and equity, safe spaces, microaggressions, trigger warnings, What is liberalism, anyway? the paradox of tolerance, the dual search for freedom and truth, free speech as the foundation of all other rights, Ostrich Parasitic Syndrome, Collective Munchausen Syndrome by Proxy, nomological networks of cumulative evidence in the quest for truth, and how big a problem are we really facing? Gad Saad, Ph.D. (Montreal, Canada), host of the popular YouTube show The Saad Truth and blogger for Psychology Today, is a professor of marketing at the John Molson School of Business at Concordia University. He holds the Concordia University Research Chair in Evolutionary Behavioral Sciences and Darwinian Consumption and is the author of The Evolutionary Bases of Consumption, plus numerous scientific papers.

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 asymptotic curve toward Truth, from Newton to Einstein to Quantum Physics, Platonic ideals/idealism, Is the universe mathematical? Where/what are “laws of nature”? What is gravity? What is causality and how is it determined? quantum entanglement and what it says about our understanding of causality, Bell’s inequality, backward causality, Hume’s “constant conjunction” definition of causality and it’s limitations, Hume’s “counterfactual” theory of causality, Bogus mechanisms of causality: impetus, ether, energy fields, ESP, The friendship of Wolfgang Pauli and Carl Jung, Jungian archetypes and how scientists think about them, God, religion, and spirituality. Paul Halpern is a professor of physics at the University of the Sciences in Philadelphia and the author of sixteen popular science books, including The Quantum Labyrinth and Einstein’s Dice and Schrödinger’s Cat. He is the recipient of a Guggenheim fellowship and is a fellow of the American Physical Society. He lives near Philadelphia, Pennsylvania.

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 pressure from the Roman Catholic Church. It was these changes that gave rise to the WEIRD psychology that would coevolve with impersonal markets, occupational specialization, and free competition — laying the foundation for the modern world. Shermer and Henrich discuss: psychology textbooks that “now purport to be about ‘Psychology’ or ‘Social Psychology’ need to be retitled something like ‘The Cultural Psychology of Late 20th Century Americans’,” Darwin’s Dictum: “How odd it is that anyone should not see that all observations must be for or against some view if it is to be of any service.” What views Henrich is writing for and against, evolutionary psychology and the search for human universals in the context of his thesis that WEIRD cultures are so different, Max Weber’s book The Protestant Ethic and the Spirit of Capitalism, and how his thesis holds up under modern studies, a 2×2 grid analysis of his thesis (what about the exceptions?): Cell 1: Catholic/Protestant Influence + WEIRD characteristics Cell 2: Catholic/Protestant Influence + non-WEIRD characteristics Cell 3: Non-Catholic/Protestant Influence + WEIRD characteristics Cell 4: Non-Catholic/Protestant Influence + non-WEIRD characteristics the problem of overdetermining the past (so many theories explaining history: Jared Diamond’s geographic models, Ian Morris’ War: What is it Good For?, Matt Ridley’s The Evolution of Everything: How New Ideas Emerge (ideas having sex), Robin Dunbar’s Grooming, Gossip, and the Evolution of Language, economic historian Gregory Clark’s A Farewell to Alms, Benjamin Friedman’s Religion and the Rise of Capitalism, Rodney Stark’s The Victory of Reason: How Christianity Led to Freedom, Capitalism, and Western Success, normative vs. descriptive accounts of human behavior polygamy vs. monogamy, 1st cousin marriages? conformity, shame and guilt, illusions, loss aversion, cognitive dissonance, confirmation bias, superstitions, religion doesn’t have to be true to be useful, national differences in cultural psychology (for example: Italy a loose culture, Germany a tight culture), origin of writing and literacy rates, origin of religion and its purpose(s), the “Big Gods” theory of religion’s origin, the purpose of religious rituals and food taboos, families and kin, kin selection, group selection, meaning and happiness in non-WEIRD cultures, “Then you get Westerners who are like ‘I’m an individual ape on a pale blue dot in the middle of a giant black space” and “What does it all mean?’”, physical differences: “WEIRD people have flat feet, impoverished microbiomes, high rates of myopia and unnaturally low levels of exposure to parasites like helminths, which may increase their risk of heart disease and allergies.”, and When we colonize Mars and become a spacefaring species, what should we take with us from what we’ve learned about human history and psychology? Joseph Henrich is an anthropologist and the author of The Secret of Our Success: How Culture Is Driving Human Evolution, Domesticating Our Species, and Making Us Smarter, among other books. He is the chair of the Department of Human Evolutionary Biology at Harvard University, where his research focuses on evolutionary approaches to psychology, decision-making, and culture.

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 we can adapt our moral thinking to survive these challenges as well. Shermer and McCullough also discuss: Darwin’s Dictum: All observation must be for or against some view if it is to be of any service. the problem to solve: why are people kind to strangers (i.e., origins of empathy, altruism, and kindness)? why we don’t need “divine command” theory to explain real morality, which can be derived through evolutionary theory plus philosophical ethical systems, evolutionary “by-product” theory: when we help strangers in the modern world we are following ancient rules of thumb that worked well enough in a world in which meeting someone for the first time was a reasonably good indicator that you’d meet them again, Frans deWaal and the “thin veneer” theory of human morality and civilization he thinks Dawkins holds, and why our morals are a thick veneer on our evolved nature, Peter Singer’s expanding circle, Norbert Elias’ The Civilizing Process and his etiquette books advisories, why stranger-adaptation and blessed-mistake theories are too simplistic, a brief overview of the past 10,000 years of moral progress, our evolved human instincts: (1) our social instincts for helping others in hopes of receiving help in return, (2) our instinct for helping others in pursuit of glory, (3) our ability to track incentives, and (4) our capacity for reason, the 7 Ages of human history: Age of Orphans, Age of Compassion, Age of Prevention, First Poverty Enlightenment, Humanitarian Big Bang, Second Poverty Enlightenment, Age of Impact, and the end of poverty, UBI, and other social tools for creating a more just society of strangers. Michael McCullough is a professor of psychology at the University of California, San Diego. The winner of numerous distinctions for his research and writing, he is a fellow of the American Psychological Association and the Society for Personality and Social Psychology. He lives in La Jolla, California.

One of the most influential physicists of our time, Stephen Hawking touched the lives of millions. Recalling his nearly two decades as Hawking’s collaborator and friend, Leonard Mlodinow brings this complex man into focus in a unique and deeply personal portrayal. We meet Hawking the genius, who employed his mind to uncover the mysteries of the universe — ultimately formulating a pathbreaking theory of black holes that reignited the discipline of cosmology and paved the way for physicists to investigate the origins of the universe in completely new ways. We meet Hawking the colleague, a man whose illness leaves him able to communicate at only six words per minute but who expends the effort to punctuate his conversations with humor. And we meet Hawking the friend, who could convey volumes with a frown, a smile, or simply a raised eyebrow. Modinow puts us in the room as Hawking indulges his passion for wine and curry; shares his feelings on love, death, and disability; and grapples with deep questions of philosophy and physics. This deeply affecting account of a friendship teaches us not just about the nature and practice of physics but also about life and the human capacity to overcome daunting obstacles. Shermer and Mlodinow discuss: what it was like working with Stephen Hawking, what Stephen Hawking was like as a person and personality, Hawking’s place in the pantheon of great physicists in the history of science, Hawking’s major contributions to physics, What is grand about the grand design of the universe? model dependent realism and the philosophy of science, Can we ever know reality? Why is there something rather than nothing? What caused the Big Bang to bang? What there was before time began? Why does the universe look fine-tuned and designed? Is the universe itself a giant black hole? Did the universe begin in a singularity? Hawking’s beliefs about God and why the concept isn’t necessary to explain the universe. Leonard Mlodinow received his PhD in theoretical physics from the University of California, Berkeley, was an Alexander von Humboldt Fellow at the Max Planck Institute, and was on the faculty of the California Institute of Technology. His previous books include the best sellers The Grand Design and A Briefer History of Time (coauthored with Stephen Hawking), Subliminal (winner of the PEN/E. O. Wilson Literary Science Writing Award), and War of the Worldviews (with Deepak Chopra), as well as Elastic, Euclid’s Window, Feynman’s Rainbow, and The Upright Thinkers.

Science is how we understand the world. Yet failures in peer review and mistakes in statistics have rendered a shocking number of scientific studies useless — or, worse, badly misleading. Such errors have distorted our knowledge in fields as wide-ranging as medicine, physics, nutrition, education, genetics, economics, and the search for extraterrestrial life. As Science Fictions makes clear, the current system of research funding and publication not only fails to safeguard us from blunders but actively encourages bad science — with sometimes deadly consequences. Yet Science Fictions is far from a counsel of despair. Rather, it’s a defense of the scientific method against the pressures and perverse incentives that lead scientists to bend the rules. By illustrating the many ways that scientists go wrong, Ritchie gives us the knowledge we need to spot dubious research and points the way to reforms that could make science trustworthy once again. Shermer and Ritchie also discuss: why we need to get science right because science deniers will pounce on such fraud, bias, negligence, and hype in science, Daryl Bem’s ESP research and what was wrong with it, “psychological priming” and the problem of replication, sleep research and the problems in Matthew Walker’s book Why We Sleep, Amy Cuddy and the problem with “Power Posture” research, Andrew Wakefield and the biggest fraud in the history of science linking vaccines & autism, diet and nutrition research and the complication of linking saturated fats, unsaturated fats, cholesterol, and heart disease, Phil Zimbardo‘s Stanford Prison Experiment, Samuel Morton’s skulls showing racial differences in head size, Steve Gould’s critique, the critique of Gould, and the critique of the critics of Gould, self-plagiarism, p values / p hacking the Schizophrenia/amaloid cascade hypothesis and why it has been hard to prove, the file-drawer problem, how to detect fraud, and Terror Management Theory and why it is almost certainly wrong. Stuart Ritchie is a lecturer in the Social, Genetic and Developmental Psychiatry Centre at King’s College London. His main research focus is human intelligence: how it relates to the brain, how much it’s affected by genetics, and how much it can be improved by factors such as education. He is a noted supporter of the Open Science movement, and has worked on tools to reform scientific practice and help scientists become more transparent when reporting their results.

Is our gender something we’re born with, or are we conditioned by society? In The End of Gender, neuroscientist and sexologist Dr. Debra Soh uses a research-based approach to address this hot-button topic, unmasking popular misconceptions about the nature vs. nurture debate and exploring what it means to be a woman or a man in today’s society. Shermer and Soh discuss: If you are transitioning to a different gender, but the word “gender” is largely meaningless biologically, then what are you transitioning to and what is the point of hormone therapy and surgery? the 1990s push to find biological basis of homosexuality so it’s not a “lifestyle choice” and how this trend has been recently reversed, the problem of putting ideology before science, cognitive creationism on the left (evolution from the neck down), why biology is not destiny, cancel culture, sex and gender, percentages of the population of LGBTQ, what you identify as vs. who you’re attracted to, individual behavior vs. collective labels, sexual orientation and gender identity, gender neutral parenting, gender dysphoria, men and women dating, trans bathrooms, prisons, and sports. Dr. Debra Soh is a neuroscientist who specializes in gender, sex, and sexual orientation. She received her doctorate from York University in Toronto and worked as an academic researcher for eleven years. Her writing has appeared in The Globe and Mail (Toronto), Harper’s Magazine, The Wall Street Journal, the Los Angeles Times, Scientific American, Playboy, Quillette, and many other publications. Her research has been published in academic journals including the Archives of Sexual Behavior and Frontiers in Human Neuroscience. As a journalist, Soh writes about the science and politics of human sexuality and gender, free speech, and censorship in academia. She lives in Toronto and divides her time between New York and Los Angeles. Follow her on Twitter at @DrDebraSoh and visit her website at DrDebraSoh.com.

The Science of Diversity uses a multidisciplinary approach to excavate the theories, principles, and paradigms that illuminate our understanding of the issues surrounding human diversity, social equality, and justice. The book brings these to the surface holistically, examining diversity at the individual, interpersonal, and international levels. Shedding light on why diversity programs fail, the book provides tools to understand how biases develop and influence our relationships and interactions with others. Shermer and Weissmark also discuss: What is diversity and how do we understand it? How is diversity related to people’s perceptions of fairness and justice? Does respect for diversity promote peace and positive change? psychology and neuroscience of classification/stereotyping, Freudianism to behaviorism to cognitive science to post-cognitive science, the self, consciousness, ai, and free will in the context of a science of diversity, revenge and justice, Israel and Palestine, nationalism: ethnic and civic, just-world theory of inequality, intergenerational justice and reparations, BLM and reparations, and the future after 2020. Mona Sue Weissmark is an American clinical psychologist and social psychologist, researcher, and author whose work on diversity and justice has received global recognition. She is best known for her groundbreaking social experiment of bringing children of Holocaust survivors face-to-face with children of Nazis, and later, grandchildren and great-grandchildren of African American slaves with descendants of slave owners. She is also a professor of psychology and author of numerous journal articles and the books: Doing Psychotherapy Effectively (University of Chicago Press); Justice Matters: Legacies of the Holocaust and World War II (Oxford University Press); The Science of Diversity (Oxford University Press).

Michael Shellenberger has been fighting for a greener planet for decades. He helped save the world’s last unprotected redwoods. He co-created the predecessor to today’s Green New Deal. And he led a successful effort by climate scientists and activists to keep nuclear plants operating, preventing a spike of emissions. But in 2019, as some claimed “billions of people are going to die,” contributing to rising anxiety, including among adolescents, Shellenberger decided that, as a lifelong environmental activist, leading energy expert, and father of a teenage daughter, he needed to speak out to separate science from fiction. His conclusion: “Climate change is real but it’s not the end of the world. It is not even our most serious environmental problem.” Despite decades of news media attention, many remain ignorant of basic facts. Carbon emissions peaked and have been declining in most developed nations for over a decade. Deaths from extreme weather, even in poor nations, declined 80 percent over the last four decades. And the risk of Earth warming to very high temperatures is increasingly unlikely thanks to slowing population growth and abundant natural gas. Curiously, the people who are the most alarmist about the problems also tend to oppose the obvious solutions. Shermer and Shellenberger also discuss: what’s really behind the rise of apocalyptic environmentalism, the powerful financial interests in environmentalism, the desire for status and power among environmentalists, along with the all-too human propensity to moralize and tell other people what to do, Shellenberger’s hypothesis that environmentalism is a faux religion primarily followed by secular people searching for transcendence, Environmental Humanism as a replacement worldview, the problems and shortcomings of climate computer models, how much warmer it’s going to get and what the consequences of that warming will be, and what we do about it? (hint: nuclear), myths about nuclear power and why people fear it, renewables, solar, wind, geothermal, and why they are not nearly as efficient as nuclear, the Amazon: Are the Earth’s lungs burning? plastic straws, recycling, electric cars, and other things, Are we in a Sixth Extinction? How have sweatshops saved the planet? How have technology and capitalism saved the whales? meat eating, Temple Grandin, and happy farms vs. factory farms, the myth of natural: what is natural is good, non-natural is bad, why environmentalism is the dominant secular religion of the educated, upper-middle-class elite in the most developed nations, with good guys and bad guys, heroes and villains, and Environmentalism as Calvinism — Richard Rhodes: “In the sense that the world is an evil place and it would be better if it were destroyed and turned back over to the natural kingdom.” Michael Shellenberger is a Time magazine “Hero of the Environment”; the winner of the 2008 Green Book Award from the Stevens Institute of Technology’s Center for Science Writings; and an invited expert reviewer of the next Assessment Report for the Intergovernmental Panel on Climate Change (IPCC). He has written on energy and the environment for the New York Times, the Washington Post, the Wall Street Journal, Nature Energy, and other publications for two decades. He is the founder and president of Environmental Progress, an independent, nonpartisan research organization based in Berkeley, California.
