167. Gary Taubes — The Case for Keto: Rethinking Weight Control and the Science and Practice of Low-Carb/High-Fat Eating

This episode is a conversation based on two of Nancy Segal’s books The Twin Children of the Holocaust: Stolen Childhood and the Will to Survive and Gay Fathers, Twin Sons: the Citzenship Case that Captured the World. Shermer and Segal discuss: her historical interest in twins research and behavior genetics • the many different types of twins and family arrangements • twins separated accidentally • twins separated intentionally • twins reunited • a brief history of twins research • Josef Mengele • Minnesota Study of Twins Reared Apart • the gay fathers and twin sons story • immigration and naturalization law related to IVF, twins, gay couples, etc. • abortion • eugenics and the Nobel Prize sperm bank • the meaning of “heritability” • the relative role of nature and nurture in how lives turn out • the “nonshared environment.” Nancy Segal is a Psychology Professor, and Director and Founder of the Twin Studies Center at California State University, Fullerton. She has authored over 300 scholarly articles and eight books. Her 2012 book, Born Together-Reared Apart: The Landmark Minnesota Twin Study, won the American Psychological Association’s William James Book Award. Her recent work, Deliberately Divided: Inside the Controversial Study of Twins and Triplets Adopted Apart, was the focus of a July 2022 BBC-TV documentary. She's a member of the editorial board of Skeptic magazine.

Did Harvard astronomer Avi Loeb discover the remnants of an interstellar meteor in the form of spherules on the ocean floor? Could they be of alien origin? In today’s special edition of The Michael Shermer Show the guest, Harvard astrophysicist Dr. Avi Loeb announces that he has discovered material from a large interstellar object from the bottom of the Pacific Ocean near Papua New Guinea in an expedition he led over the summer. The object, which he labels IM1—Interstellar Meteor 1—collided with Earth nearly a decade ago and was tracked by U.S. government satellites, which gave Loeb and his team coordinates of where to look. Most of the meteor burned up in the atmosphere but tiny spherules remained on the ocean bottom, which Loeb retrieved and had analyzed in labs at Harvard, UC Berkeley, and the Broker Corporation. These spherules are tiny—smaller than a grain of sand—and there are literally trillions of them around the world of both terrestrial and extraterrestrial origin, so whether or not these particular spherules are Interstellar in origin remains to be seen, despite Loeb’s confidence that they are. Here is what he announced today in a press release: The Interstellar Expedition of June 2023–led by the expedition’s Chief Scientist, Harvard University Astrophysicist Avi Loeb and coordinated by Expedition Leader Rob McCallum of EYOS Expeditions retrieved hundreds of metallic spheres thought to be unmatched to any existing alloys in our solar system from the seafloor in the Pacific Ocean near Papua New Guinea. Early analysis shows that some spherules from the meteor path contain extremely high abundances of Beryllium, Lanthanum and Uranium, labeled as a never-seen-before “BeLaU” composition. These spherules also exhibit iron isotope ratios unlike those found on Earth, the Moon and Mars, altogether implying an interstellar origin. The loss of volatile elements is consistent with IM1’s airburst in the Earth’s atmosphere. “The “BeLaU” composition is tantalizingly different by factors of hundreds from solar system materials, with beryllium production through spallation of heavier nuclei by cosmic-rays flagging interstellar travel,” says Avi Loeb. The press release of August 29, 2023 was timed with the publication date of Dr. Loeb’s new book, Interstellar, whose subtitle hints at the scientist’s larger ambitions: The Search for Extraterrestrial Life and Our Future in the Stars. Dr. Loeb’s co-authored paper has not been peer reviewed. In fact, none of the world’s leading experts on spherules from space have even seen any of Dr. Loeb’s evidence. So in preparation for this episode, I contacted Peter Brown, an astronomer at Western University, Ontario, who specializes in the physics of meteors, and he directed me to the five leading experts in the world on spherules. These include: George Flynn, SUNY, Plattsburgh; Don Brownlee, University of Washington; John Bradley, University of Hawaii; Michael Zolensky, NASA; and Matthew Genge, Imperial College, London. I also consulted Steven Desch, from Arizona State University, as he has been quoted elsewhere as a critic of Avi Loeb’s research. All expressed their skepticism about Dr. Loeb’s findings, which I read on air to Avi to get his response. (See the show notes for this episode on skeptic.com.) Listen to the experts and Dr. Loeb’s response to their skepticism in this episode. (Note: Steven Desch’s initial statement, included in the show notes, was so negative that I chose not to read it on air, but include it in the show notes on skeptic.com for full disclosure of what he thinks about this research. I also included Dr. Desch’s additional comments on why many scientists are skeptical of the U.S. government data on the meteor’s trajectory and impact site.) I should note that I am a member of the Galileo Project team, which organized this expedition, and I consider Avi a friend and colleague who always welcomes my skepticism in our weekly team meetings. To that end let me emphasize that he is not claiming to have discovered alien technology, only the remnants of an interstellar object. Unfortunately, the media coverage surrounding the Galileo Project in general and this expedition in particular is only interested in whether or not we have made contact with ET. We have not, and Avi is not claiming that we have. No matter the scientific find is, the media reports it as aliens, aliens, and aliens. Alas. My own view is that aliens are very likely out there somewhere—given the astronomical numbers of hundreds of billions of galaxies, each of which has hundreds of billions of stars, each of which has planets it seems highly unlikely that we’re alone in the cosmos—but that they have very likely not come here in any shape or form—nonhuman biologics or extraterrestrial metalogics (my own neologism echoing government whistleblower David Grusch’s ridiculous description of alien pilots as “nonhuman biologics” in his Congressional testimony). The universe is vast and consists of mostly empty space. The odds are very long indeed that anyone could find us, much less leave traces for us to evaluate. But in keeping with Cromwell’s Rule in Bayesian reasoning (never assign a 0 or 1 probability to anything because, as Oliver Cromwell famously said, “I beseech you in the bowels of Christ you might be mistaken”), we should keep an open mind and keep looking. That is why I support the SETI program and am on the Galileo Project team. The odds are long but the payoff would be spectacular if we ever did discover extraterrestrial intelligence or the technological artifacts of an extraterrestrial civilization. Abraham (Avi) Loeb is the Frank B. Baird, Jr., Professor of Science at Harvard University, the longest-serving chair of Harvard’s Department of Astronomy, the founding director of Harvard’s Black Hole Initiative, and the current director of the Institute for Theory and Computation (ITC) within the Harvard-Smithsonian Center for Astrophysics. He also heads the Galileo Project, chairs the Advisory Committee for the Breakthrough Starshot Initiative, and is former chair of the Board on Physics and Astronomy of the National Academies. Author of eight books and more than a thousand scientific papers, Loeb is an elected fellow of the American Academy of Arts and Sciences, the American Physical Society, and the International Academy of Astronautics. In 2012, Time selected Loeb as one of the 25 most influential people in space. He lives near Boston, Massachusetts.

New attention from historians and journalists is raising pointed questions about the founding period: was the American revolution waged to preserve slavery, and was the Constitution a pact with slavery or a landmark in the antislavery movement? We have long needed a history of the founding that fully includes Black Americans in the Revolutionary protests, the war, and the debates over slavery and freedom that followed. We now have that history in Pulitzer Prize–winning historian Edward J. Larson’s insightful synthesis of the founding. Throughout Larson’s brilliant history, it is the voices of Black Americans that prove the most convincing of all on the urgency of liberty. Shermer and Larson discuss: Was America founded in 1619 or 1776? • What is/was an “American”? • Founding Fathers attitudes toward slavery • What was the justification of slavery? • constitutional convention and slavery compromises • U.S. Constitution and slavery • Thirteenth, Fourteenth, and Fifteenth Amendments • Atlantic slave trade • Fugitive Slave Act and Clause • Native Americans • monogenism vs. polygenism • slavery abolition • Quakers push for abolition • Three-fifths Compromise • The Dread Scott Decision and the Civil War • Abraham Lincoln and his rational argument for ending slavery • the future of race relations in America. Edward J. Larson is the author of many acclaimed works in American history, including the Pulitzer Prize–winning history of the Scopes Trial, Summer for the Gods. He also authored Franklin and Washington: The Founding Partnership, The Return of George Washington 1783-1789, A Magnificent Catastrophe: The Tumultuous Election of 1800—America’s First Presidential Campaign, An Empire of Ice: Scott, Shackleton, and the Heroic Age of Antarctic Science, To the Edges of the Earth: 1909, the Race for the Three Poles, and the Climax of the Age of Exploration, and the textbook Evolution: The Remarkable History of a Scientific Theory. He is University Professor of History and Hugh and Hazel Darling Chair in Law at Pepperdine University.

“Don’t let the perfect be the enemy of the good.” —anonymous “Perfection is man’s ultimate illusion. It simply doesn’t exist in the universe. If you are a perfectionist, you are guarantee to be a loser in whatever you do.” —David Burns Today, burnout and depression are at record levels, driven by a combination of intense workplace competition, oppressively ubiquitous social media encouraging comparisons with others, the quest for elite credentials, and helicopter parenting. Society continually broadcasts the need to want more, and to be perfect. Shermer and Curran discuss: • Curran’s own perfectionism and how that led him to research perfection • What is perfection? Is he measuring perfection or something else? • The Big Five Personality Scale (OCEAN) and where perfection falls in it • goals, meritocracy, high standards, and conscientiousness • self-oriented vs. other-oriented vs. socially prescribed perfectionism • Steve Jobs, Michael Jordan, Lance Armstrong • origins of perfectionism • consequences of perfectionism • social media • income inequality, UBI, GDP, economics • helicopter parenting and coddling • generational differences in perfectionism. Thomas Curran is a professor of psychology at the London School of Economics and author of a landmark study that the BBC hailed as “the first to compare perfectionism across generations.” His TED talk on perfectionism has received more than three million views. His research has been featured in media ranging from the Harvard Business Review to New Scientist to CNN and he has appeared on numerous television and radio programs. He is the author of The Perfection Trap: Embracing the Power of Good Enough.

From phishing scams to Ponzi schemes, fraudulent science to fake art, chess cheaters to crypto hucksters, and marketers to magicians, our world brims with deception. In Nobody’s Fool, psychologists Daniel Simons and Christopher Chabris show us how to avoid being taken in. They describe the key habits of thinking and reasoning that serve us well most of the time but make us vulnerable—like our tendency to accept what we see, stick to our commitments, and overvalue precision and consistency. Each chapter illustrates their new take on the science of deception, describing scams you’ve never heard of and shedding new light on some you have. Simons and Chabris provide memorable maxims and practical tools you can use to spot deception before it’s too late. Christopher Chabris is a professor at Geisinger, a Pennsylvania healthcare system, where he co-directs the Behavioral Insights Team. He previously taught at Union College and Harvard University, and is a Fellow of the Association for Psychological Science. Chris received his Ph.D. in psychology and A.B. in computer science from Harvard. His research focuses on decision-making, attention, intelligence, and behavior genetics. His work has been published in leading journals including Science, Nature, PNAS, and Perception, and he has published essays in the Wall Street Journal, New York Times, and Washington Post. Chris is also a chess master, games enthusiast, and co-author of the bestselling book The Invisible Gorilla: How Our Intuitions Deceive Us. Together Daniel and Christopher co-authored the new book Nobody’s Fool: Why We Get Taken In and What We Can Do about It. Shermer, Simons, and Chabris discuss: • How rational vs. irrational are humans? (Daniel Kahneman vs. Gerd Gingerenzer) • Truth Default Theory, or Truth Bias • deception vs. deception detection • social proof and the influence of others on our beliefs • cults • Bernie Madoff • Harvey Weinstein • Elizabeth Holmes and Theranos • Nigerian spam scam • cheating in chess • habits of thought that can be exploited • information hooks we find especially enticing instead of triggering skepticism • scientific fraud and the replication crisis • how to prevent from being a victim of fraud or a con.

Everyone wants to be happy. The question “How can I be happy?” drives countless decisions across the world, and billions of dollars are spent on marketing a wide variety of answers to it. Increasing evidence shows, however, that unhappiness is on the rise. Already known to an audience of hundreds of thousands as “the therapist for everyone,” Dr. Saad contends that happiness is not merely a changeable mood, but a process toward which all people can strive by following basic steps known to humans for millennia; happiness can be measured and assessed, and strategies devised to achieve it. Drawing on scientific studies, the wisdom of ancient philosophy and religion, and his extraordinary personal experience as a refugee from war-torn Lebanon, Gad offers a provocative, helpful, and entertaining treatise on how to strive for happiness, win it, and keep it. Gad Saad, PhD, one of the best-known public intellectuals fighting the tyranny of political correctness, is a professor of marketing at the John Molson School of Business at Concordia University, where he held the Research Chair in Evolutionary Behavioral Sciences and Darwinian Consumption from 2008 to 2018. A pioneer in the application of evolutionary psychology to consumer behavior, he is the author of The Evolutionary Bases of Consumption, The Consuming Instinct, and numerous scientific papers and the editor of the book Evolutionary Psychology in the Business Sciences. His previous bestselling popular trade book is The Parasitic Mind: How Infectious Ideas Are Killing Common Sense. His new book is The Saad Truth about Happiness: 8 Secrets for Leading the Good Life. Shermer and Saad discuss: operational definitions of the “good life,” “happiness,” and “well being” • emotions • eudaimonia (the pursuit of meaning) versus hedonism (the pursuit of pleasure) • genetics and heritability • cultural components • the Big Five (OCEAN) • marriage (mate selection) • health • exercise and stress reduction • religion • anti-fragility • a playful outlook and curiosity • variety (the “spice of life”) • what the ancient Greeks got right about living the good life • how failure may actually be a key to more happiness • persistence, grit, and risk taking • regret and the dark side of consumption and addictions.

In this conversation based on his new book, America’s Cultural Revolution, Christopher Rufo exposes the inner history of the intellectuals and militants who slowly and methodically captured America’s institutions. With profiles of Herbert Marcuse, Angela Davis, Paulo Freire, and Derrick Bell, Rufo shows how activists have profoundly influenced American culture with an insidious mix of Marxism and racialist ideology. Through deep historical research, Rufo shows how the ideas first formulated in the pamphlets of the Weather Underground, Black Panther Party, and Black Liberation Army have been sanitized and adopted as the official ideology of America’s prestige institutions, from the Ivy League universities to the boardrooms of Walmart, Disney, and Bank of America. Shermer and Rufo discuss: race as America’s original sin • civil rights movement then and now • liberalism vs. illiberalism • equality vs. equity • overt racism vs. systemic racism • intellectual origins of the cultural revolution: Herbert Marcuse, Angela Davis, Paulo Freire, Derrick Bell, Eldridge Cleaver, Huey Newton • Black Lives Matter origins in the Black Liberation Army and the Black Panthers • critical race theory (CRT) • diversity, equity and inclusion (DEI), and more… Christopher Rufo is a writer, filmmaker, and activist. He has directed four documentaries for PBS, including America Lost, which tells the story of three forgotten American cities. He is a senior fellow of the Manhattan Institute and a contributing editor of the public policy magazine City Journal. His reporting and activism have inspired a presidential order, a national grassroots movement, and legislation in 22 states. Christopher holds a Bachelor of Science in Foreign Service from Georgetown University and a Master’s of Liberal Arts from Harvard University.
