The Trouble with Economic Data: Flawed Metrics, Flawed Decisions
The Michael Shermer Show
The ways that statisticians and governments measure the economy were developed in the 1940s, when the urgent economic problems were entirely different from those of today. Diane Coyle argues that the framework underpinning today’s economic statistics is so outdated that it functions as a distorting lens, or even a set of blinkers. When policymakers rely on such an antiquated conceptual tool, how can they measure, understand, and respond with any precision to what is happening in today’s digital economy? Coyle argues that to understand the current economy, we need different data collected...

What’s Holding You Back? Scott Barry Kaufman on Resilience in the Age of Fragility
The Michael Shermer Show
It’s tempting to see ourselves as damaged or powerless—defined by past traumas, overwhelming emotions, and daily struggles. But is that really the most helpful way to understand ourselves? Does seeing ourselves as victims lead to growth? Psychologist and author Scott Barry Kaufman joins us to examine how popular narratives around sensitivity, self-esteem, and emotional regulation may be holding us back. He unpacks the psychological costs of coddling (vs. empowerment), the rise of risk aversion, and how modern parenting, education, and therapy shape our sense of self. With insight, empathy,...

Why do ordinary people carry out extraordinary harm when simply told to do so? From the Holocaust to the genocides in Rwanda, Bosnia, and Cambodia, history shows how obedience to authority can lead to unimaginable acts. But what’s happening in the brain when we follow orders—even ones that conflict with our morals? In this episode, we speak with neuroscientist Emilie Caspar, whose groundbreaking research explores how authority influences cognition and behavior. Drawing from real-life accounts of genocide perpetrators and cutting-edge neuroscience, Caspar reveals how obedience can...

What Einstein Meant by God: Science, Spirituality, and the Search for Meaning
The Michael Shermer Show
Albert Einstein remains renowned around the world for revolutionizing our understanding of the cosmos, but very few realize that the celebrated scientist had a deep spiritual side. Einstein believed that one wondrous force was woven through all things everywhere—and this sense of the pervasive sacred influenced every aspect of his existence, from his marvelous science to his passionate pacifism. Kieran Fox studied medicine at Stanford University and holds a doctorate in cognitive neuroscience from the University of British Columbia. He is a physician-scientist at the The University of...

What Happened to the Intellectual Dark Web?
The Michael Shermer Show
Outside of the academics and activists whose ideology came to dominate the West in the second decade of the twenty-first century, arguably no group influenced public discourse as much as the Intellectual Dark Web. Challenging the intellectual and cultural orthodoxies that engulfed universities, the media, and big tech, this group—a loose collective of politically diverse intellectuals, commentators, and scholars critical of political correctness, identity politics, and cancel culture—relied on alternative platforms like podcasts, digital magazines, and YouTube to promote free speech,...

Sex and Beauty: The Extraordinary Implications of Darwin’s Strangest Idea (Matt Ridley)
The Michael Shermer Show
In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. Matt Ridley revisits Darwin’s revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution. Ridley also explores the scientific research into the evolution of bright colors, exotic ornaments, and elaborate displays in birds around the world. Charles Darwin thought the purpose of such displays was...
info_outlineThe guests today are co-authors of a new paper in Science Advances titled: “A reassessment of the ‘hard-steps’ model for the evolution of intelligent life.”
Jennifer Macalady is a Professor of Geosciences at the Pennsylvania State University. Her research is focused on microbial ecology and evolution, and interactions between microorganisms and Earth materials like minerals and water through geologic time.
Daniel B. Mills is a postdoctoral researcher in the Orsi Geomicrobiology Lab at The University of Munich in Germany. His research focuses on the co-evolutionary history of Earth's surface environment and eukaryotic life—a topic he approaches by studying modern marine organisms and environments. He also applies this research to the ongoing search for exoplanetary biosignatures and technosignatures.
Shermer, Mills, and Macalady discuss the Hard Steps model of the evolution of intelligent life, the Drake Equation, the Fermi Paradox, the Great Filter, and the Great Silence. They also cover the Rare Earth hypothesis, major transitions in evolution, the uniqueness of humans, and the search for biosignatures and technosignatures.
