Our lives are composed of millions of choices, ranging from trivial to life-changing and momentous. Luckily, our brains have evolved a number of mental shortcuts, biases, and tricks that allow us to quickly negotiate this endless array of decisions. We don’t want to rationally deliberate every choice we make, and thanks to these cognitive rules of thumb, we don’t need to.
Yet these hard-wired shortcuts, mental wonders though they may be, can also be perilous. They can distort our thinking in ways that are often invisible to us, leading us to make poor decisions, to be easy targets for manipulators…and they can even cost us our lives.
The truth is, despite all the buzz about the power of gut-instinct decision-making in recent years, sometimes it’s better to stop and say, “On second thought . . .”
The trick, of course, lies in knowing when to trust that instant response, and when to question it. In On Second Thought, acclaimed science writer Wray Herbert provides the first guide to achieving that balance. Drawing on real-world examples and cutting-edge research, he takes us on a fascinating, wide-ranging journey through our innate cognitive traps and tools, exposing the hidden dangers lurking in familiarity and consistency; the obstacles that keep us from accurately evaluating risk and value; the delusions that make it hard for us to accurately predict the future; the perils of the human yearning for order and simplicity; the ways our fears can color our very perceptions . . . and much more.
Along the way, Herbert reveals the often-bizarre cross-connections these shortcuts have secretly ingrained in our brains, answering such questions as why jury decisions may be shaped by our ancient need for cleanliness; what the state of your desk has to do with your political preferences; why loneliness can literally make us shiver; how drawing two dots on a piece of paper can desensitize us to violence… and how the very typeface on this page is affecting your decision about whether or not to buy this book.
Ultimately, On Second Thought is both a captivating exploration of the workings of the mind and an invaluable resource for anyone who wants to learn how to make smarter, better judgments every day.
Praise for On Second Thought:
"Eminently "Gladwellian"...Herbert clearly shows the effects of various daily mental maneuvers and peppers the text with explanations of how the human mind has evolved." —Washington Post
"Brings a twist [to the psychology shelf]...could keep us from making mistakes whose consequences range from dying in an avalanche to failing to follow directions because we don't like the font they're written in." —Sharon Begley, Newsweek
"Think twice before you trust your gut...Herbert uses real-world examples and cutting-edge research to show how heuristics--hardwired mental shortcuts we think of as intuition--can both help and hinder the decisions we make every day." —US News & World Report
“Counters the argument set forth in titles like Malcom Gladwell's Blink… successfully shows readers how ancient shortcuts can impact our modern living and how to use this knowledge to make better decisions.” —Library Journal
“Wray Herbert displays his gifts as a science writer par excellence…On Second Thought goes a long way toward leveling the mental playing field by outing the hidden power of our unconscious mental models.” —Daniel Goleman, author of Emotional Intelligence
"There is one way to be rational, and many ways of being irrational. With stories, anecdotes, and studies, Wray Herbert takes us through a guided tour of our many irrational tendencies, holding our hand, and helping us to see the mistakes we all make every day."—Dan Ariely, author of Predictably Irrational
“A wonderful book that should be read by the public and experts alike…the most complete statement currently available on the foibles manifest in everyday decision-making and surely one of the most interesting books that I have had the pleasure of reading." —Ellen Langer, author of Mindfulness
“Wray Herbert is one of our finest writers of psychological science…here he blends the most fascinating findings from cognitive psychology with his own experiences into a seamless story of the mental biases and quirks that help us navigate through life—and occasionally get us stuck in brambles. On second thought . . . I’d say the same thing.”
—Carol Tavris, coauthor of Mistakes Were Made
“A fascinating and important book that reveals the invisible errors we make time and again… don’t tackle any big adventures or major undertakings until you’ve read On Second Thought. It could save your nest egg, your relationship, and even your life. No kidding!”—Sarah Susanka, author of The Not So Big Life
“From ‘looming maladaptive style’ to the ‘cooties heuristic,’ Wray Herbert takes us on a journey through the styles of thought we usually take for granted. In clear and lively prose, he describes psych experiments and real-life quandaries that reveal how our cognitive habits get in our way – or, occasionally, save our skins. It all adds up to a fascinating book that is altogether a treat. —Robin Marantz Henig, author of Pandora's Baby: How the First Test Tube Babies Sparked the Reproductive Revolution
