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.

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.

Vividly written and exhaustively researched, Jonathan Eig’s King: A Life is the first major biography in decades of the civil rights icon Martin Luther King Jr. — and the first to include recently declassified FBI files. In this revelatory new portrait of the preacher and activist who shook the world, the bestselling biographer gives us an intimate view of the courageous and often emotionally troubled human being who demanded peaceful protest for his movement but was rarely at peace with himself. He casts fresh light on the King family’s origins as well as MLK’s complex relationships with his wife, father, and fellow activists. King reveals a minister wrestling with his own human frailties and dark moods, a citizen hunted by his own government, and a man determined to fight for justice even if it proved to be a fight to the death. As he follows MLK from the classroom to the pulpit to the streets of Birmingham, Selma, and Memphis, Eig dramatically re-creates the journey of a man who recast American race relations and became our only modern-day founding father — as well as the nation’s most mourned martyr. Shermer and Eig discuss: how to write biography • the history of the King family going back to slavery, Jim Crow, etc. • the influence of King Sr. on Martin’s intellectual and emotional development and the Ebenezer Baptist Church • King’s early experience with racism in the south • King’s religious beliefs and the influence of his faith on his civil rights activism • the influence of Gandhi and Reinhold Niebuhr on King’s strategic activism and deep belief in nonviolence • King’s politics • Malcolm X • Native Americans • gay rights • accusations of plagiarism, and more… Jonathan Eig is a former senior writer for the Wall Street Journal. He is the New York Times bestselling author of several books, including Ali: A Life; Luckiest Man: The Life and Death of Lou Gehrig; and Opening Day: The Story of Jackie Robinson’s First Season. Ken Burns calls him “a master storyteller,” and Eig’s books have been listed among the best of the year by the Washington Post, Chicago Tribune, Sports Illustrated, and Slate. He lives in Chicago with his wife and children.

Right now, someone, somewhere is being cancelled. Off-the-cuff tweets or “harmless” office banter have the potential to wreck lives. The Left condemns the Right, and the bigotry of the old elites. The Right complains about brain-dead political correctness, and the erosion of liberal values. In reality, both sides are colluding in a reactionary, exclusionary politics that is as self-defeating as it is divisive. Can the Left escape this extremism and stay true to the progressive ideals it once professed? In this provocative conversation based on his new book, Umut Özkirimli reveals the similarities between right-wing populism and radical identity politics, and sets out an alternative vision. Shermer and Özkirimli discuss: identity politics, cancel culture • woke, TERF, anti-fragility, anti-racism • diversity, equity, and inclusion • Ibram X. Kendi, Robin DiAngelo • Loretta Ross, rape, retributive vs. restorative justice • Woman’s March • leftism, progressivism, democratic socialism, liberalism, classical liberalism, libertarianism, conservatism, populism, nationalism, white nationalism, authoritarianism, tyranny • moral panics • MAGA, Trump • victimhood • safetyism • trigger warnings, safe spaces, microaggressions • What Went Wrong? Umut Özkirimli is a senior research fellow at IBEI (Institut Barcelona d’Estudis Internacionals), a professor at Blanquerna, Ramon Llull University, and a senior research associate at CIDOB (Barcelona Centre for International Affairs).
