146. Donald Prothero — Weird Earth: Debunking Strange Ideas About Our Planet

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.

The Science of Revenge: Why Getting Even Feels So Good

The Science of Revenge: Why Getting Even Feels So Good

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.

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

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

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.

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

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

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 Fate of Nations: Why Ignoring Human Nature Dooms Politics

The Fate of Nations: Why Ignoring Human Nature Dooms Politics

Science writer Nicholas Wade explains how human nature continues to shape—and sometimes destabilize—modern civilization, and argues that ignoring the effects of human nature on politics is one of society’s greatest mistakes. Drawing on anthropology, evolutionary biology, and history, Wade shows how deep-rooted traits not only shape the outcomes of certain political beliefs and systems, but also affect how people form families, religion, and social order. Nicholas Wade has worked at Nature and Science, and, for many years, at The New York Times, where he was an editorial writer and science editor. He is the author of four books about recent human evolution. His latest is The Origin of Politics: How Evolution and Ideology Shape the Fate of Nations.
