"This bracing yet accessible work is the right book at the right time. In a world clouded by nonsense, The Life-Changing Science of Detecting Bullshit is a welcome ray of sunshine.”
―Daniel H. Pink, New York Times bestselling author of When, Drive, and To Sell is Human

"We’ve all consumed and produced our share of bullshit, but John Petrocelli has spent his career studying it. This is the perfect moment for his thoughtful, readable book on the psychology of detecting fake news in the world around us―and false beliefs about ourselves too.”
―Adam Grant, New York Times bestselling author of Think Again and Originals, and host of the TED podcast WorkLife

"[A] spirited debut . . . Petrocelli shines . . . His advice for not getting taken advantage of is sound and straight-forward . . . readers will appreciate the wealth of examples and practical advice."
―Publishers Weekly

"In this era of media-controlled information, we are challenged to identify truth from distortions. We now all have the essential tool needed in Professor Petrocelli's masterpiece, The Life-Changing Science of Detecting Bullshit. Our vision is sharpened by this new bullshit-detection lens we extract from the abundant examples and guidelines that fill this uniquely eye-opening journey."
―Philip Zimbardo, Stanford University, author of the New York Times bestseller The Lucifer Effect: Understanding How Good People Turn Evil

"Never before in the history of our species have human beings been subjected to such an unceasing avalanche of utter bullshit on a daily basis. OK―technically that statement might itself be bullshit... and if you want to be able to tell whether or not it is, you should read John Petrocelli's funny, fascinating, and entirely not-bullshit new book."
―Heidi Grant, PhD, author of 9 Things Successful People Do Differently and Reinforcements: How to Get People to Help You

“Our society is plagued by climate denial, anti-vaccine campaigns, fake-news, alternative facts, post-truth claims, and conspiracy theories, so the science of detecting bullshit has never been more important. John Petrocelli’s new book perfectly identifies the problem and offers a solution. Bullshit is pervasive but science, reason, and rationality are even more powerful, and with the tools Petrocelli provides we can continue to bend the arc of history toward truth."
―Michael Shermer, New York Times bestselling author of Why People Believe Weird Things

“At last, in the form of John Petrocelli’s highly engaging new book, we have straight talk about the doubletalk, flowing sewage-like around us these days. Better still, he walks his talk with scientifically-grounded, actionable information on precisely how to recognize and reject the bilge.”
―Robert Cialdini, New York Times bestselling author of Influence and Pre-Suasion

"Professor Petrocelli pulls no punches. He doesn’t simply lay out the tools for identifying b.s., he applies them to known bullshitters like car salespeople and Donald Trump, and to people many of us trust. You’ll never view a Ted talk, wine ranking, or drug advertisement the same."
―Barry Glassner, author of the bestselling Culture of Fear: Why Americans Are Afraid of the Wrong Things

"Each revolution in communication technology, from the printing press to the internet, has been misused to flood the public with foolish and deceitful news. John Petrocelli’s entertaining book documents the nonsense beliefs that connect and divide us, about wine, food, diamonds, politics, Ponzi schemes, and personality tests. He explains valuable rules that protect us from being taken in and, above all, reminds us that the 21st century should be the juncture at which humanity finally enters the age of enlightenment."
―Gerd Gigerenzer, Max Planck Institute, author of Risk Savvy: How to Make Good Decisions

"No one seeks to be irrational; no one embraces beliefs they know to be false; and no one chooses to be a sucker. Yet, it is only through critical thinking that we can avoid such outcomes, and such ability does not come naturally. I know of no better or more enjoyable way to become a critical thinker than through this very impressive book. It both teaches and entertains in a most delightful way. I strongly recommend it."
―James Alcock, York University, author of Belief: What it Means to Believe and Why Our Convictions Are So Compelling

"Why do so many people believe things that are not true? It’s sometimes because of superstition, dogma, or bullshit. Dr. Petrocelli, a premier researcher who studies bullshit, has explored this problem in an engaging book that both educates and entertains. In The Life-Changing Science of Detecting Bullshit, he offers wisdom on the causes of bullshit, the potential benefits to the bullshitter, and the downside for everyone else. Readers will learn how to detect bullshitting and eliminate it’s negative effects. We’ll all be a lot better off (except the bullshitters, who might have to find another way to be)."
―Elizabeth Loftus, former President of the Association for Psychological Science, and author of Witness for the Defense

"This book is a fun read, but its purpose is dead serious. We all hate liars, but smirk at the bullshitter -- why? John Petrocelli shows us that bullshit can be just as dangerous as lies, and that common sense is not enough to defend yourself. From how to buy a diamond ring, to what Deepak Chopra and Donald Trump have in common, this book equips you with cutting-edge research from social psychology that will help you from being taken in by that person most likely to deceive you....yourself."
―Lee McIntyre, author of Post-Truth

"This is the ultimate consumer protection guide―how to protect ourselves from the bullshit, utter nonsense, lies, distortions, conspiracy thinking, and disinformation swirling all about us. John Petrocelli is an experimental psychologist who studies bullshit, and his book is clear and blunt: If we are to avoid falling victim to the B.S., we must learn how to recognize and decisively bury it using scientific reasoning and critical thinking to seek evidence and truth."
―Kendrick Frazier, editor, Skeptical Inquirer

"At last, a brilliantly argued case pointing out that, despite appearing humorous, bullshit is deadly serious. Anyone making any important decision should read this."
―Kevin Duncan, author of The Business Bullshit Book
