The Michael Shermer Show Michael Shermer

For thousands of years, humans have wondered whether we’re alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life?
As founding director of Cornell University’s Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth’s history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview - planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality.
With the James Webb Space Telescope and Dr. Kaltenegger’s pioneering work, she shows that we live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide, Dr. Kaltenegger shows how we discover not merely new continents, like the explorers of old, but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we’re not alone?
Lisa Kaltenegger is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell and Associate Professor in Astronomy. She is a pioneer and world-leading expert in modeling potential habitable worlds and their detectable spectral fingerprint. Kaltenegger serves on the National Science Foundation’s Astronomy and Astrophysics Advisory Committee (AAAC), and on NASA senior review of operating missions. She is a Science Team Member of NASA’s TESS Mission as well as the NIRISS instrument on James Webb Space Telescope. Kaltenegger was named one of America’s Young Innovators by Smithsonian magazine, an Innovator to Watch by Time magazine. She appears in the IMAX 3D movie “The Search for Life in Space” and speaks frequently, including at Aspen Ideas Festival, TED Youth, World Science Festival and the Kavli Foundation lecture at the Adler Planetarium.
Shermer and Kaltenegger discuss: Carl Sagan and his influence • Sagan’s Dragon • ECREE Principle • how stars, planets and solar systems form • how exoplanets are discovered • Hubble Space Telescope, Kepler Space Telescope, James Webb Space Telescope • The Origin of Life • Fermi’s Paradox: where is everybody (the Great Silence, the Great Filter) • biosignatures • technosignatures • Dyson spheres • Will aliens be biological or AI? • interstellar travel • Kardashev scale of civilizations • how to talk to aliens when we can’t even talk to dolphins • Deities for Atheists, Skygods for Skeptics: aliens as gods and the search as religion • why alien worlds matter.

We all want to be happier, but our brains often get in the way. When we’re too stuck in our heads we obsess over our inadequacies, compare ourselves with others and fail to see the good in our lives. In The Science of Happiness, world-leading psychologist and happiness expert Bruce Hood demonstrates that the key to happiness is not self-care but connection. He presents seven simple but life-changing lessons to break negative thought patterns and re-connect with the things that really matter.
Alter Your Ego Avoid Isolation Reject Negative Comparisons Become More Optimistic Control Your Attention Connect With Others Get Out of Your Own Head Grounded in decades of studies in neuroscience and developmental psychology, this book tells a radical new story about the roots of wellbeing and the obstacles that lie in our path. With clear, practical takeaways throughout, Professor Hood demonstrates how we can all harness the findings of this science to re-wire our thinking and transform our lives.
Dr. Bruce Hood is an award-winning Professor of Developmental Psychology at Bristol University and the author of several books including SuperSense, The Self Illusion, The Domesticated Brain, and Possessed. His course, The Science of Happiness, is the most popular course at Bristol University. He has appeared extensively on TV and radio, including co-hosting the BBC podcast The Happiness Half Hour in 2021. He is a Fellow of the American Psychological Society, the Royal Institution of Great Britain and the British Psychological Society.
Shermer and Hood discuss: psychedelic drugs • defining the “good life” or “happiness” • measuring emotions • happiness as social contagion • eudaimonia (the pursuit of meaning) versus hedonism (the pursuit of pleasure) • genetics and heritability • cultural components • WEIRD people • The Big Five (OCEAN) • marriage and health • exercise and stress reduction • what the ancient Greeks got right about living the good life • how failure may actually be a key to more happiness • how to live the life you want—not necessarily the life expected of you.

Robin Reames breaks down the major techniques of rhetoric, pulling back the curtain on how politicians, journalists, and “journalists” convince us to believe what we believe—and to talk, vote, and act accordingly.
Understanding these techniques helps us avoid being manipulated by authority figures who don’t have our best interests at heart. It also grants us rare insight into the values that shape our own beliefs.
Reames and Shermer discuss: rhetoric vs. facts (rhetorical truths vs. empirical truths) • the point of reason (to understand reality or to persuade?) • Canons of rhetoric: invention, arrangement, style, memory, delivery • bullshitters vs. liars • induction and deduction • rhetorical, ideological, and metaphorical thinking • how to debate contentious issues
Robin Reames is associate professor of English at the University of Illinois at Chicago, specializing in rhetorical theory and the history of ideas. Her new book is The Ancient Art of Thinking for Yourself: The Power of Rhetoric in Polarized Times.

We push ourselves toward the highest-paying, most prestigious jobs, seeking promotions and public recognition. As Adam Gopnik points out, the result is not so much a rat race as a rat maze, with no way out. Except one: to choose accomplishment over achievement.
Achievement is the completion of the task imposed from outside.
Accomplishment, by contrast, is the end point of an engulfing activity one engages in for its own sake.
Shermer and Gopnik discuss:
mastering the secrets of stage magic (Gopnik's son worked with David Blaine and Jamy Ian Swiss) accomplishment in music family and mentors the concept of the 10,000-hour rule vs. natural talent Adam's new book All That Happiness Is, which offers timeless wisdom against the grain. Adam Gopnik has been a staff writer at The New Yorker since 1986. He is the author of numerous best-selling books, including Paris to the Moon and The Real Work: On the Mystery of Mastery.

But what if things go right?
