168. Daniel Dennett & Gregg Caruso — Just Deserts: Debating Free Will (moderated by Michael Shermer)

Dr. Nancy Segal, the world’s leading expert on twins, has a new book that sheds light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins. Using the latest scientific findings from psychology, psychiatry, biology, and education, Dr. Segal separates fact from fiction. Each idea about twins is described, followed by both a short answer about the truth, and then a longer, more detailed explanation. Coverage includes embryology of twins, twin types, intellectual growth, personality traits, sexual orientation of twins, marital relationships, epigenetic analyses, the frequency of different twin types and the varieties of polar body twin pairs. This book, and Salon with Dr. Segal, will inform and entertain behavioral and life science researchers, health professionals, twins, parents of twins, and anyone interested in the fascinating topic of twins and what they can teach us about human nature. Dr. Segal earned her Ph.D. in the Social Sciences and Behavioral Sciences from the University of Chicago. From 1982-1991 she was a post-doctoral fellow and research associate at the University of Minnesota, affiliated with the well-known Minnesota Study of Twins Reared Apart. She is currently Professor of Psychology at CSU Fullerton and Director of the Twin Studies Center, which she founded in 1991. Dr. Segal has authored over 200 scientific articles and book chapters, as well as several books on twins. Her previous book, Born Together-Reared Apart: The Landmark Minnesota Twin Study (2012, Harvard University Press) won the 2013 William James Book Award from the American Psychological Association. Her other books include Someone Else’s Twin: The True Story of Babies Switched at Birth (2011), Indivisible by Two: Lives of Extraordinary Twins (2007) and Entwined Lives: Twins and What They Tell Us About Human Behavior (2000). She is the 2016 recipient of the Wang Family Excellence Award from the California State University administrators and trustees for “exemplary contributions and achievement.” She was recognized as CSUF’s Outstanding Professor of the Year in 2005 and as the Distinguished Faculty Member in Humanities and Social Sciences in 2007 and 2014. She has been a frequent guest on national and international television and radio programs, including the Martha Stewart Show, Good Morning America, the Oprah Winfrey Show and The Forum (BBC). Dr. Segal has variously served as a consultant and expert witness for the media, the law and the arts.

Are mass violence and catastrophes the only forces that can seriously decrease economic inequality? To judge by thousands of years of history, the answer is yes. Tracing the global history of inequality from the Stone Age to today, the Stanford University historian Walter Scheidel shows that inequality never dies peacefully. Inequality declines when carnage and disaster strike and increases when peace and stability return. The Great Leveler is the first book to chart the crucial role of violent shocks in reducing inequality over the full sweep of human history around the world. Ever since humans began to farm, herd livestock, and pass on their assets to future generations, economic inequality has been a defining feature of civilization. Over thousands of years, only violent events have significantly lessened inequality. The “Four Horsemen” of leveling—mass-mobilization warfare, transformative revolutions, state collapse, and catastrophic plagues—have repeatedly destroyed the fortunes of the rich. Scheidel identifies and examines these processes, from the crises of the earliest civilizations to the cataclysmic world wars and communist revolutions of the twentieth century. Today, the violence that reduced inequality in the past seems to have diminished, and that is a good thing. But it casts serious doubt on the prospects for a more equal future. An essential contribution to the debate about inequality, The Great Leveler provides important new insights about why inequality is so persistent—and why it is unlikely to decline anytime soon.

Why do we catch colds? What causes seasons to change? And if you fire a bullet from a gun and drop one from your hand, which bullet hits the ground first? In a pinch we almost always get these questions wrong. Worse, we regularly misconstrue fundamental qualities of the world around us. In Scienceblind, cognitive and developmental psychologist Dr. Andrew Shtulman, a professor of psychology and cognitive science at Occidental College, where he directs the Thinking Lab, shows that the root of our misconceptions lies in the theories about the world we develop as children. They’re not only wrong, they close our minds to ideas inconsistent with them, making us unable to learn science later in life. So how do we get the world right? We must dismantle our intuitive theories and rebuild our knowledge from its foundations. The reward won’t just be a truer picture of the world, but clearer solutions to many controversies—around vaccines, climate change, or evolution—that plague our politics today.

Why is it so hard to say “I made a mistake”—and really believe it? Social psychologist Dr. Carol Tavris, one of the most influential thinkers and writers of our time, explores in dialogue with Michael Shermer cognitive dissonance and what happens when we make mistakes, cling to outdated attitudes, or mistreat other people—we must calm the cognitive dissonance that jars our feelings of self-worth. And so, unconsciously, we create fictions that absolve us of responsibility, restoring our belief that we are smart, moral, and right—a belief that often keeps us on a course that is dumb, immoral, and wrong. Backed by years of research, Mistakes Were Made (But Not by Me) offers a fascinating explanation of self-justification—how it works, the damage it can cause, and how we can overcome it. The updated edition of the book features new examples and concludes with an extended discussion of how we can live with dissonance, learn from it, and perhaps, eventually, forgive ourselves.

Among Americans, diabetes is more prevalent today than ever; obesity is at epidemic proportions; nearly 10% of children are thought to have nonalcoholic fatty liver disease. And sugar is at the root of these, and other, critical society-wide, health-related problems. With his signature command of both science and straight talk, Gary Taubes delves into Americans’ history with sugar: its uses as a preservative, as an additive in cigarettes, the contemporary overuse of high-fructose corn syrup. He explains what research has shown about our addiction to sweets. He clarifies the arguments against sugar, corrects misconceptions about the relationship between sugar and weight loss; and provides the perspective necessary to make informed decisions about sugar as individuals and as a society. This is a groundbreaking and eye opening expose that makes the convincing case that sugar is the tobacco of the new millennium, backed by powerful lobbies, entrenched in our lives, and utterly addicting, making us all very sick. As Katie Couric says, “This is required reading for not only ever parent, but every American.” Gary Taubes is the New York Times bestselling author of Good Calories, Bad Calories and Why We Get Fat. His writing has appeared in the New York Times magazine, The Atlantic, and Esquire.

Dr. Priyamvada Natarajan is a cosmologist and theoretical astrophysicist from Yale University, specializing in dark matter, dark energy, and black holes. She also holds the Sophie and Tycho Brahe Professorship of the Dark Cosmology Centre, Niels Bohr Institute, at the University of Copenhagen, Denmark. She is passionate about sharing science with the general public and in her new book she provides a tour of the “greatest hits” of cosmological discoveries—the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan is at the forefront of this research—an astrophysicist who literally creates maps of invisible matter in the universe. In the book, she not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes—these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.

Dr. Benjamin Bergen is a professor of cognitive science at the University of California, San Diego, and in his new book he explains why profanity is so appealing to us. Let’s face it, we all swear. Whether we’re happy or mad, uttering a four-letter word seems to be a natural occurrence for most of us. But why do we swear, even when we know we’re breaking cultural taboos? Why are some words off limits in certain countries or deemed offensive in past centuries but are considered perfectly tame in others? What does all this g*ddamn swearing tell us about our language and our brains? Bergen has the answers as he illuminates the controversial and complex nature of profanity and its relationship on our culture.
