The acclaimed New York Times and Wall Street Journal bestseller from Robert Cialdini—“the foremost expert on effective persuasion” (Harvard Business Review)—explains how it’s not necessarily the message itself that changes minds, but the key moment before you deliver that message. What separates effective communicators from truly successful persuaders? With the same rigorous scientific research and accessibility that made his Influence an iconic bestseller, Robert Cialdini explains how to prepare people to be receptive to a message before they experience it. Optimal persuasion is achieved only through optimal pre-suasion. In other words, to change “minds” a pre-suader must also change “states of mind.” Named a “Best Business Books of 2016” by the Financial Times, and “compelling” by The Wall Street Journal, Cialdini’s Pre-Suasion draws on his extensive experience as the most cited social psychologist of our time and explains the techniques a person should implement to become a master persuader. Altering a listener’s attitudes, beliefs, or experiences isn’t necessary, says Cialdini—all that’s required is for a communicator to redirect the audience’s focus of attention before a relevant action. From studies on advertising imagery to treating opiate addiction, from the annual letters of Berkshire Hathaway to the annals of history, Cialdini outlines the specific techniques you can use on online marketing campaigns and even effective wartime propaganda. He illustrates how the artful diversion of attention leads to successful pre-suasion and gets your targeted audience primed and ready to say, “Yes.” His book is “an essential tool for anyone serious about science based business strategies…and is destined to be an instant classic. It belongs on the shelf of anyone in business, from the CEO to the newest salesperson” (Forbes).

How a Nobel Prize–winning theory of the mind altered our perception of reality. Forty years ago, Israeli psychologists Daniel Kahneman and Amos Tversky wrote a series of breathtakingly original studies undoing our assumptions about the decision-making process. Their papers showed the ways in which the human mind erred, systematically, when forced to make judgments in uncertain situations. Their work created the field of behavioral economics, revolutionized Big Data studies, advanced evidence-based medicine, led to a new approach to government regulation, and made much of Michael Lewis’s own work possible. Kahneman and Tversky are more responsible than anybody for the powerful trend to mistrust human intuition and defer to algorithms. The Undoing Project is about a compelling collaboration between two men who have the dimensions of great literary figures. They became heroes in the university and on the battlefield―both had important careers in the Israeli military―and their research was deeply linked to their extraordinary life experiences. Amos Tversky was a brilliant, self-confident warrior and extrovert, the center of rapt attention in any room; Kahneman, a fugitive from the Nazis in his childhood, was an introvert whose questing self-doubt was the seedbed of his ideas. They became one of the greatest partnerships in the history of science, working together so closely that they couldn’t remember whose brain originated which ideas, or who should claim credit. They flipped a coin to decide the lead authorship on the first paper they wrote, and simply alternated thereafter. This story about the workings of the human mind is explored through the personalities of two fascinating individuals so fundamentally different from each other that they seem unlikely friends or colleagues. In the process they may well have changed, for good, mankind’s view of its own mind.

*Major New York Times Bestseller *More than 2.6 million copies sold *One of The New York Times Book Review's ten best books of the year *Selected by The Wall Street Journal as one of the best nonfiction books of the year *Presidential Medal of Freedom Recipient *Daniel Kahneman's work with Amos Tversky is the subject of Michael Lewis's best-selling The Undoing Project: A Friendship That Changed Our Minds In his mega bestseller, Thinking, Fast and Slow, Daniel Kahneman, world-famous psychologist and winner of the Nobel Prize in Economics, takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think. System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. The impact of overconfidence on corporate strategies, the difficulties of predicting what will make us happy in the future, the profound effect of cognitive biases on everything from playing the stock market to planning our next vacation―each of these can be understood only by knowing how the two systems shape our judgments and decisions. Engaging the reader in a lively conversation about how we think, Kahneman reveals where we can and cannot trust our intuitions and how we can tap into the benefits of slow thinking. He offers practical and enlightening insights into how choices are made in both our business and our personal lives―and how we can use different techniques to guard against the mental glitches that often get us into trouble. Topping bestseller lists for almost ten years, Thinking, Fast and Slow is a contemporary classic, an essential book that has changed the lives of millions of readers.

NEW YORK TIMES BESTSELLER • The instant classic about why some ideas thrive, why others die, and how to make your ideas stick. “Anyone interested in influencing others—to buy, to vote, to learn, to diet, to give to charity or to start a revolution—can learn from this book.”—The Washington Post Mark Twain once observed, “A lie can get halfway around the world before the truth can even get its boots on.” His observation rings true: Urban legends, conspiracy theories, and bogus news stories circulate effortlessly. Meanwhile, people with important ideas—entrepreneurs, teachers, politicians, and journalists—struggle to make them “stick.” In Made to Stick, Chip and Dan Heath reveal the anatomy of ideas that stick and explain ways to make ideas stickier, such as applying the human scale principle, using the Velcro Theory of Memory, and creating curiosity gaps. Along the way, we discover that sticky messages of all kinds—from the infamous “kidney theft ring” hoax to a coach’s lessons on sportsmanship to a vision for a new product at Sony—draw their power from the same six traits. Made to Stick will transform the way you communicate. It’s a fast-paced tour of success stories (and failures): the Nobel Prize-winning scientist who drank a glass of bacteria to prove a point about stomach ulcers; the charities who make use of the Mother Teresa Effect; the elementary-school teacher whose simulation actually prevented racial prejudice. Provocative, eye-opening, and often surprisingly funny, Made to Stick shows us the vital principles of winning ideas—and tells us how we can apply these rules to making our own messages stick. From Publishers Weekly Starred Review. Unabashedly inspired by Malcolm Gladwell's bestselling The Tipping Point, the brothers Heath—Chip a professor at Stanford's business school, Dan a teacher and textbook publisher—offer an entertaining, practical guide to effective communication. Drawing extensively on psychosocial studies on memory, emotion and motivation, their study is couched in terms of "stickiness"—that is, the art of making ideas unforgettable. They start by relating the gruesome urban legend about a man who succumbs to a barroom flirtation only to wake up in a tub of ice, victim of an organ-harvesting ring. What makes such stories memorable and ensures their spread around the globe? The authors credit six key principles: simplicity, unexpectedness, concreteness, credibility, emotions and stories. (The initial letters spell out "success"—well, almost.) They illustrate these principles with a host of stories, some familiar (Kennedy's stirring call to "land a man on the moon and return him safely to the earth" within a decade) and others very funny (Nora Ephron's anecdote of how her high school journalism teacher used a simple, embarrassing trick to teach her how not to "bury the lead"). Throughout the book, sidebars show how bland messages can be made intriguing. Fun to read and solidly researched, this book deserves a wide readership. (Jan. 16) Copyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved. From School Library Journal Adult/High School—While at first glance this volume might resemble the latest in a series of trendy business advice books, ultimately it is about storytelling, and it is a how-to for crafting a compelling narrative. Employing a lighthearted tone, the Heaths apply those selfsame techniques to create an enjoyable read. They analyze such narratives as urban legends and advertisements to discover what makes them memorable. The authors provide a simple mnemonic to remember their stickiness formula, and the basic principles may be applied in any situation where persuasiveness is an asset. The book is a fast read peppered with exercises to test the techniques proposed. Some examples act as pop quizzes and engage readers in moments of self-reflection. The book draws on examples from teachers, scientists, and soldiers who have been successful at crafting memorable ideas, from the well-known blue eye/brown eye exercise conducted by an Iowa elementary school teacher as an experiential lesson in prejudice following the assassination of Martin Luther King, Jr., to conversations among Xerox repairmen. Readers who enjoyed Malcolm Gladwell's Blink (2005) and The Tipping Point (2000, both Little, Brown) will appreciate this clever take on contemporary culture.—Heidi Dolamore, San Mateo County Library, CA Copyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved. From Bookmarks Magazine Chip and Dan Heath—a Stanford professor and an education entrepreneur, respectively—attempt to determine why one idea succeeds while another fails. What could have been a dry marketing textbook is, instead, a generally engaging narrative generously endowed with anecdotes and instructive sidebars. The Wall Street Journal expressed annoyance at the profusion of personal stories, while the Washington Post cited some problems with the overall framework. Overall, however, Made to Stick is a worthy addition to the spate of recent books that explain why we do the things we do and how this self-knowledge can be used more effectively. "Anyone interested in influencing others—to buy, to vote, to learn, to diet, to give to charity or to start a revolution—can learn from this book" (Washington Post). Copyright © 2004 Phillips & Nelson Media, Inc. From Booklist Based on a class at Stanford taught by one of the authors, this book profiles how some ideas "stick" in our minds while the majority fall by the wayside. Urban legends, conspiracy theories, and compelling advertising make up much of the intrinsically interesting examples that the Heaths profile that qualify for "stickiness." This book explores what makes social epidemics "epidemic" and, as the Heaths cite from Malcolm Gladwell's Tipping Point (2000), defines the secret recipe that makes an idea viral. The principles of stickiness are examined--an unexpected outcome, lots of concrete details that we remember, emotion, simplicity, and credibility--all packaged in an easily told story format. Taking these five stickiness attributes, the book offers numerous examples of how these properties make up the stories we are all familiar with--the urban legend about kidney theft and the razor blades supposedly lurking in Halloween candy. Exercises, checklists, and other tools are sprinkled throughout the book to help the reader understand and test how stickiness can be applied to their ideas, whether they are teachers, parents, or CEOs.

Excerpt. © Reprinted by permission. All rights reserved. I I N T R O D U C T I O N WHAT STICKS? A friend of a friend of ours is a frequent business traveler. Let’s call him Dave. Dave was recently in Atlantic City for an important meeting with clients. Afterward, he had some time to kill before his flight, so he went to a local bar for a drink. He’d just finished one drink when an attractive woman approached and asked if she could buy him another. He was surprised but flattered. Sure, he said. The woman walked to the bar and brought back two more drinks—one for her and one for him. He thanked her and took a sip. And that was the last thing he remembered. Rather, that was the last thing he remembered until he woke up, disoriented, lying in a hotel bathtub, his body submerged in ice. He looked around frantically, trying to figure out where he was and how he got there. Then he spotted the note: don’t move. call 911. A cell phone rested on a small table beside the bathtub. He picked it up and called 911, his fingers numb and clumsy from the ice. The operator seemed oddly familiar with his situation. She said, “Sir, I want you to reach behind you, slowly and carefully. Is there a tube protruding from your lower back?” Anxious, he felt around behind him. Sure enough, there was a tube. The operator said, “Sir, don’t panic, but one of your kidneys has been harvested. There’s a ring of organ thieves operating in this city, and they got to you. Paramedics are on their way. Don’t move until they arrive.” You’ve just read one of the most successful urban legends of the past fifteen years. The first clue is the classic urban-legend opening: “A friend of a friend . . .” Have you ever noticed that our friends’ friends have much more interesting lives than our friends themselves? You’ve probably heard the Kidney Heist tale before. There are hundreds of versions in circulation, and all of them share a core of three elements: (1) the drugged drink, (2) the ice-filled bathtub, and (3) the kidney-theft punch line. One version features a married man who receives the drugged drink from a prostitute he has invited to his room in Las Vegas. It’s a morality play with kidneys. Imagine that you closed the book right now, took an hourlong break, then called a friend and told the story, without rereading it. Chances are you could tell it almost perfectly. You might forget that the traveler was in Atlantic City for “an important meeting with clients”—who cares about that? But you’d remember all the important stuff. The Kidney Heist is a story that sticks. We understand it, we remember it, and we can retell it later. And if we believe it’ s true, it might change our behavior permanently—at least in terms of accepting drinks from attractive strangers. Contrast the Kidney Heist story with this passage, drawn from a paper distributed by a nonprofit organization. “Comprehensive community building naturally lends itself to a return-on-investment rationale that can be modeled, drawing on existing practice,” it begins, going on to argue that “[a] factor constraining the flow of resources to CCIs is that funders must often resort to targeting or categorical requirements in grant making to ensure accountability.” Imagine that you closed the book right now and took an hourlong break. In fact, don’t even take a break; just call up a friend and retell that passage without rereading it. Good luck. Is this a fair comparison—an urban legend to a cherry-picked bad passage? Of course not. But here’s where things get interesting: Think of our two examples as two poles on a spectrum of memorability. Which sounds closer to the communications you encounter at work? If you’re like most people, your workplace gravitates toward the nonprofit pole as though it were the North Star. Maybe this is perfectly natural; some ideas are inherently interesting and some are inherently uninteresting. A gang of organ thieves—inherently interesting! Nonprofit financial strategy—inherently uninteresting! It’s the nature versus nurture debate applied to ideas: Are ideas born interesting or made interesting? Well, this is a nurture book. So how do we nurture our ideas so they’ll succeed in the world? Many of us struggle with how to communicate ideas effectively, how to get our ideas to make a difference. A biology teacher spends an hour explaining mitosis, and a week later only three kids remember what it is. A manager makes a speech unveiling a new strategy as the staffers nod their heads enthusiastically, and the next day the frontline employees are observed cheerfully implementing the old one. Good ideas often have a hard time succeeding in the world. Yet the ridiculous Kidney Heist tale keeps circulating, with no resources whatsoever to support it. Why? Is it simply because hijacked kidneys sell better than other topics? Or is it possible to make a true, worthwhile idea circulate as effectively as this false idea? The Truth About Movie Popcorn Art Silverman stared at a bag of movie popcorn. It looked out of place sitting on his desk. His office had long since filled up with fake-butter fumes. Silverman knew, because of his organization’ s research, that the popcorn on his desk was unhealthy. Shockingly unhealthy, in fact. His job was to figure out a way to communicate this message to the unsuspecting moviegoers of America. Silverman worked for the Center for Science in the Public Interest (CSPI), a nonprofit group that educates the public about nutrition. The CSPI sent bags of movie popcorn from a dozen theaters in three major cities to a lab for nutritional analysis. The results surprised everyone. The United States Department of Agriculture (USDA) recommends that a normal diet contain no more than 20 grams of saturated fat each day. According to the lab results, the typical bag of popcorn had 37 grams. The culprit was coconut oil, which theaters used to pop their popcorn. Coconut oil had some big advantages over other oils. It gave the popcorn a nice, silky texture, and released a more pleasant and natural aroma than the alternative oils. Unfortunately, as the lab results showed, coconut oil was also brimming with saturated fat. The single serving of popcorn on Silverman’s desk—a snack someone might scarf down between meals—had nearly two days’ worth of saturated fat. And those 37 grams of saturated fat were packed into a medium-sized serving of popcorn. No doubt a decentsized bucket could have cleared triple digits. The challenge, Silverman realized, was that few people know what “37 grams of saturated fat” means. Most of us don’t memorize the USDA’s daily nutrition recommendations. Is 37 grams good or bad? And even if we have an intuition that it’s bad, we’d wonder if it was “bad bad” (like cigarettes) or “normal bad” (like a cookie or a milk shake). Even the phrase “37 grams of saturated fat” by itself was enough to cause most people’s eyes to glaze over. “Saturated fat has zero appeal,” Silverman says. “It’s dry, it’s academic, who cares?” Silverman could have created some kind of visual comparison— perhaps an advertisement comparing the amount of saturated fat in the popcorn with the USDA’ s recommended daily allowance. Think of a bar graph, with one of the bars stretching twice as high as the other. But that was too scientific somehow. Too rational. The amount of fat in this popcorn was, in some sense, not rational. It was ludicrous. The CSPI needed a way to shape the message in a way that fully communicated this ludicrousness. Silverman came up with a solution. CSPI called a press conference on September 27, 1992. Here’s the message it presented: “A medium-sized ‘butter’ popcorn at a typical neighborhood movie theater contains more artery-clogging fat than a bacon-and-eggs breakfast, a Big Mac and fries for lunch, and a steak dinner with all the trimmings—combined!” The folks at CSPI didn’t neglect the visuals—they laid out the full buffet of greasy food for the television cameras. An entire day’ s worth of unhealthy eating, displayed on a table. All that saturated fat— stuffed into a single bag of popcorn. The story was an immediate sensation, featured on CBS, NBC, ABC, and CNN. It made the front pages of USA Today, the Los Angeles Times, and The Washington Post’s Style section. Leno and Letterman cracked jokes about fat-soaked popcorn, and headline writers trotted out some doozies: “Popcorn Gets an ‘R’ Rating,” “Lights, Action, Cholesterol!” “Theater Popcorn is Double Feature of Fat.” The idea stuck. Moviegoers, repulsed by these findings, avoided popcorn in droves. Sales plunged. The service staff at movie houses grew accustomed to fielding questions about whether the popcorn was popped in the “bad” oil. Soon after, most of the nation’ s biggest theater chains—including United Artists, AMC, and Loews— announced that they would stop using coconut oil.

Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives? The primary obstacle is a conflict that’s built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems—the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie. The rational mind wants to change something at work; the emotional mind loves the comfort of the existing routine. This tension can doom a change effort—but if it is overcome, change can come quickly. In Switch, the Heaths show how everyday people—employees and managers, parents and nurses—have united both minds and, as a result, achieved dramatic results: ● The lowly medical interns who managed to defeat an entrenched, decades-old medical practice that was endangering patients. ● The home-organizing guru who developed a simple technique for overcoming the dread of housekeeping. ● The manager who transformed a lackadaisical customer-support team into service zealots by removing a standard tool of customer service In a compelling, story-driven narrative, the Heaths bring together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change. Switch shows that successful changes follow a pattern, a pattern you can use to make the changes that matter to you, whether your interest is in changing the world or changing your waistline. Amazon.com Review Chip Heath and Dan Heath on Switch: How to Change Things When Change Is Hard "Change is hard." "People hate change." Those were two of the most common quotes we heard when we began to study change. But it occurred to us that if people hate change, they have a funny way of showing it. Every iPhone sold serves as counter-evidence. So does every text message sent, every corporate merger finalized, every aluminum can recycled. And we haven’t even mentioned the biggest changes: Getting married. Having kids. (If people hate change, then having a kid is an awfully dumb decision.) It puzzled us--why do some huge changes, like marriage, come joyously, while some trivial changes, like submitting an expense report on time, meet fierce resistance? We found the answer in the research of some brilliant psychologists who’d discovered that people have two separate “systems” in their brains—a rational system and an emotional system. The rational system is a thoughtful, logical planner. The emotional system is, well, emotional—and impulsive and instinctual. When these two systems are in alignment, change can come quickly and easily (as when a dreamy-eyed couple gets married). When they’re not, change can be grueling (as anyone who has struggled with a diet can attest). In those situations where change is hard, is it possible to align the two systems? Is it possible to overcome our internal "schizophrenia" about change? We believe it is. In our research, we studied people trying to make difficult changes: People fighting to lose weight and keep it off. Managers trying to overhaul an entrenched bureaucracy. Activists combatting seemingly intractable problems such as child malnutrition. They succeeded--and, to our surprise, we found striking similarities in the strategies they used. They seemed to share a similar game plan. We wanted, in Switch, to make that game plan available to everyone, in hopes that we could show people how to make the hard changes in life a little bit easier. --Chip and Dan Heath (Photo © Amy Surdacki) From Publishers Weekly The Heath brothers (coauthors of Made to Stick) address motivating employees, family members, and ourselves in their analysis of why we too often fear change. Change is not inherently frightening, but our ability to alter our habits can be complicated by the disjunction between our rational and irrational minds: the self that wants to be swimsuit-season ready and the self that acquiesces to another slice of cake anyway. The trick is to find the balance between our powerful drives and our reason. The authors' lessons are backed up by anecdotes that deal with such things as new methods used to reform abusive parents, the revitalization of a dying South Dakota town, and the rebranding of megastore Target. Through these lively examples, the Heaths speak energetically and encouragingly on how to modify our behaviors and businesses. This clever discussion is an entertaining and educational must-read for executives and for ordinary citizens looking to get out of a rut. (Mar.)

One Saturday in 2000, some unsuspecting moviegoers showed up at a suburban theater in Chicago to catch a 1:05 P.M matinee of Mel Gibson's action flick Payback. They were handed a soft drink and a free bucket of popcorn and asked to stick around after the movie to answer a few questions about the concession stand. These movie fans had unwittingly entered a study of irrational eating behavior.1 There was something unusual about the popcorn they received. It was wretched. In fact, it had been carefully engineered to be wretched. It'd been popped five days earlier and was so stale that it squeaked when you ate it. One moviegoer later compared it to Styrofoam packing peanuts, and two others, forgetting that they'd received the popcorn for free, demanded their money back. Some of them got their free popcorn in a medium-sized bucket, and others got a large bucket--the sort of huge tub that looks like it might once have been an above-ground swimming pool. Everybody got their own individual bucket so there'd be no need to share. The researchers responsible for the study were interested in a simple question: Would the people with bigger buckets eat more? Both buckets were designed to be so big that no one could finish their portion. So the actual research question was a bit more specific: Would somebody with a larger inexhaustible supply of popcorn eat more than someone with a smaller inexhaustible supply? The sneaky researchers weighed the buckets before and after the movie, so they were able to measure precisely how much popcorn each person ate. The results were stunning: People with the large buckets ate 53 percent more popcorn than people with the medium size. That's the equivalent of 173 more calories and approximately 21 extra hand-dips into the bucket.2 The author of the study, Brian Wansink, runs the Food and Brand Lab at Cornell University and he described the results in his book Mindless Eating: "We've run other popcorn studies, and the results were always the same, however we tweaked the details. It didn't matter if our moviegoers were in Pennsylvania, Illinois, or Iowa, and it didn't matter what kind of movie was showing; all of our popcorn studies led to the same conclusion. People eat more when you give them a bigger container. Period." No other theory explains the behavior. These people weren't eating for pleasure. (The popcorn was so stale it squeaked!) They weren't driven by a desire to "finish their portion." (Both buckets were too big to finish.) It didn't matter whether they were hungry or full. The equation is unyielding: Bigger container = more eating. Best of all, people refused to believe the results. After the movie, the researchers told the moviegoers about the two bucket sizes and the findings of their past research. The researchers asked, do you think you ate more because of the larger size? The vast majority scoffed at the idea, saying things like, "Things like that don't trick me," or "I'm pretty good at knowing when I'm full." Whoops. 2. Imagine that someone showed you the data from this study but didn't mention the bucket sizes. On your data summary, you'd see how much popcorn each person ate. You could quickly scan the results and see the differences--some people ate a little bit of popcorn, some ate a lot, and some seem determined to test the physical limits of the human stomach. Armed with a data set like that, you would have found it easy to jump to conclusions. Some people in the world are Reasonable Snackers and others are Big Gluttons. A public health expert, studying that data alongside you, would likely get very worried about the Gluttons. We need to motivate these people to adopt healthier snacking behaviors! Let's find ways to show them the health hazards of eating so much! And maybe we should approach state legislators about a Big Bucket Ban! But wait a second. If you want people to eat less popcorn, the solution is pretty simple: Just give them smaller buckets. You don't have to worry about their knowledge or their attitudes. You can see how easy it would be to turn an easy change problem (shrinking people's buckets) into a hard change problem (influencing people's motivation or understanding, or changing the law). And that's the first surprise about change: What looks like a people problem is often a situation problem. 3. This is a book to help you change things when change is hard. We'll consider change at every level--individual, organizational, and societal. Maybe you want to help your brother beat his gambling addiction. Maybe you need your team at work to act more frugally because of market conditions. Maybe you wish more of your neighbors would bike to work. Usually these topics are treated separately--there is "change management" advice for executives and "self-help advice" for individuals and "change the world" advice for activists. That's a shame, because all change efforts have something in common: For anything to change, someone has to start acting differently. Your brother has got to stay out of the casino; your employees have got to start booking coach fares. Ultimately, all change efforts boil down to the same mission: Can you get people to start behaving in a new way? We know what you're thinking--people resist change. But it's not quite that easy. Babies are born every day to parents who, inexplicably, welcomed the change. Think about the sheer magnitude of that change! Such an idea would never fly in the work world: Would anyone agree to work for a boss who'd wake you up twice a night, screaming, for trivial administrative duties? And what if, every time you wore a new piece of clothing, the boss spit up on it? Yet people don't resist this massive change--they volunteer for it. Enormous changes are all around us, and they often come voluntarily--not just babies, but marriages and new homes and new technologies and new job duties. Meanwhile, other behaviors are maddeningly intractable. Smokers keep smoking and kids grow fatter and your husband can't ever seem to get his dirty shirts into a hamper. So there are hard changes and easy changes. What distinguishes one from the other? In this book, we'll argue that successful changes share a common pattern--they require the leader of the change to do three things at once. We've already seen the first of those three things: To change someone's behavior, you've got to change their situation. The situation isn't the whole game, of course. An alcoholic might go dry in rehab, but what happens when they leave? Your sales reps might be hyper-productive when the sales manager shadows them, but what happens afterward? For someone's behavior to change, you've got to influence not just their environment but their hearts and minds. The trick is this: Often the heart and mind disagree. Fervently. 4. Consider the Clocky. It's an alarm clock invited by an MIT student and now manufactured by Nanda Home. It's no ordinary alarm clock--it has wheels. You set it at night and in the morning when the alarm goes off, it rolls off your nightstand and scurries around the room, forcing you to chase it down. Picture the scene: You're crawling around the bedroom in your underwear, stalking and cursing a runaway clock. Clocky ensures that you won't snooze-button your way to disaster. And apparently that's a common fear, since about 35,000 Clockys have sold, at $50 each, in its first 2 years on the market. The success of this invention reveals a lot about our psychology. What it means, fundamentally, is that we are schizophrenic. Part of us--our rational side--wants to get up at 5:45 a.m., allowing plenty of time for a quick jog before we leave for the office. The other part of us--the emotional side--wakes up in the darkness of the early morning, snoozing inside a warm cocoon of sheets and blankets, and wants nothing in the world so much as a few more minutes of sleep. If, like us, your emotional side tends to win these internal debates, then you might be a potential Clocky customer. The beauty of the device is that it allows your rational side to outsmart your emotional side. It's simply impossible to stay cuddled up under the covers when there's a rogue alarm clock rolling around your room. Let's be blunt here: Clocky is not a product for a sane species. If Spock wants to get up at 5:45 a.m., he'll just get up. No drama required. Our built-in schizophrenia is a deeply weird thing, but we don't think much about it, because we're so used to it. When we kick off a new diet, we toss the Cheetohs and Oreos out of the pantry, because our rational side knows that when our emotional side gets a craving, there's no hope of self-control. The only option is to remove the temptation altogether. (For the record, some MIT student will make a fortune designing Cheetohs that scurry away from people when they're on a diet.) The unavoidable conclusion is this: Your brain isn't of one mind. The conventional wisdom in psychology, in fact, is that our brains have two independent systems at work at all times. First, there's what we called the emotional side. It's the part of you that is instinctive, that feels pain and pleasure. Second, there's the rational side, also known as the reflective or conscious system. It's the part of you that deliberates and analyzes and looks into the future. Psychologists have learned a lot about these two systems in the past few decades, but of course mankind has always been aware of the tension. Plato said that in our heads we've got a rational charioteer who has to rein in an unruly horse who "barely yields to horsewhip and goad combined." Freud wrote of the selfish id and the conscientious superego (and the ego who mediates between them). More recently behavioral economists have dubbed the two systems the Planner and the Doer. But, to us, the duo's tension was captured best by an analogy used by the University of Virginia psychologist Jonathan Haidt in his wonderful book The Happiness Hypothesis. Haidt said that our emotional side is an Elephant, and our rational side is its Rider. The Rider, perched atop the Elephant, holds the reins and seems to be the leader. The Rider's control is precarious, though, because he's so tiny relative to the Elephant. Anytime the 6-ton Elephant disagrees with the direction, the Rider is going to lose. He's completely overmatched. Most of us are all too familiar with situations where the Elephant overpowers our Rider. You've experienced this if you've ever: slept in, overeaten, dialed up your ex at midnight, procrastinated a report, tried to quit smoking and failed, skipped the gym, gotten angry and said something you regretted, abandoned your Spanish or jitterbug or piano lessons, refused to speak up in a meeting because you were scared, etc. Good thing no one is keeping score. So the weakness of the Elephant, our emotional and instinctive side, is clear: It is lazy and skittish, often looking for the quick payoff (ice cream cone) over the long-term payoff (being thin). When change efforts fail, it's usually the Elephant's fault, since the kinds of change we want typically involve short-term sacrifices for long-term payoffs. (We cut back on expenses today to yield a better balance sheet next year. We avoid ice cream today for a better body next year.) Changes often fail because the Rider simply can't keep the Elephant on the road long enough to reach the destination. The Elephant's weakness--the hunger for short-term _payoffs--is the mirror image of the Rider's strength, which is the ability to think long-term, to plan, to think beyond the moment. (All those things that your pet can't do.) But what may surprise you is that the Elephant also has enormous strengths and that the Rider has crippling weaknesses. The Elephant isn't always the bad guy. Emotion is the Elephant's turf--love and compassion and sympathy and loyalty. That fierce instinct you have to protect your kids against harm--that's the Elephant. That spine-stiffening you feel when you need to stand up for yourself--that's the Elephant. Just as important, the Elephant is the one who gets things done. To make progress toward a goal, whether it's noble or crass, requires the energy and drive of the Elephant. This strength is the mirror image of the Rider's great weakness: spinning his wheels. The Rider tends to over-analyze and overthink things. If you've ever met someone who can agonize for 20 minutes about what to eat for dinner, or if you've had a manager who could brainstorm about new ideas for hours but never seemed to get around to doing anything, you've met the Rider. The challenge of a change agent is to appeal to both. If you reach the Riders of your team but not the Elephants, they'll have understanding without motivation. If you reach their Elephants but not their Riders, they'll have passion without direction. In both cases, their flaws can be paralyzing--a reluctant Elephant and a wheel-spinning Rider can both ensure that nothing changes. But when they are moving together, change can come easily. 5. It's not easy to achieve balance between the Rider and the Elephant, because change creates tension between them. When we change, we abandon behaviors that are comfortable and automatic in favor of new behaviors that are less familiar. Because they are less familiar, they require careful supervision by the Rider, who must lead the Elephant down an unfamiliar trail. Think of how we feel "on guard" when meeting new people, as compared with our effortless interactions with old friends. One set of behaviors is conscious and stage-managed ("Soooo nice to meet you!") and the other is natural, unconscious. When we change, we replace unconscious behaviors with conscious ones, and that can be exhausting. To see what we mean, we want to invite you to participate in a famous psychology experiment called the Stroop Test. The Stroop Test is simple enough: On the next page, you're going to see a list of words. (Please note--the color version of the test will only appear in the finished book. To see the test in color, go to http://www.madetostick.com/resources/stroop.pdf.) Your job is simply to say, aloud, the color of each word in the list. For instance, if you saw these three words_._._._ HAT____CAT____BLACK ._._._you'd say, "Black, Black, Black," since all three are printed in black ink. (Please do say the words aloud to get the full effect. If you're in public, people will just think you're talking on a really, really tiny cell phone.) Flip the page when you're ready. STOP    GO      DOG FISH    FROG    JUICE GREEN   RED     BLACK BLUE    GREEN   ORANGE RED     BLACK   GREEN GREEN   BLUE    BLACK RED     GREEN   BLUE GREEN   RED     ORANGE BLUE    RED     BLUE It felt pretty easy at first, didn't it? When the word and the color were the same, it was effortless. But then came the roadblock--the word "GREEN," which was printed in orange. Suddenly, your progress slowed. People who take the Stroop Test perform pretty consistently. Once they hit that first roadblock, their answer speed is essentially cut in half. That's because a behavior that was automatic suddenly becomes conscious. When you hit the orange-colored word "GREEN," your brain calls a supervisor on duty, whose job is to examine each word carefully and separate GREEN-the-Word from Orange-Its-Color and serve up the word "Orange" to your lips. Notice something remarkable: Your 3-year-old son or nephew, who can't read, could easily outperform you on this test, because he wouldn't have to call a supervisor. (Indeed, you'd do well if you took the Stroop Test in Chinese--you wouldn't recognize the symbols, so they couldn't throw you off.)

Chip and Dan Heath, the bestselling authors of Switch and Made to Stick, tackle one of the most critical topics in our work and personal lives: how to make better decisions. Research in psychology has revealed that our decisions are disrupted by an array of biases and irrationalities: We’re overconfident. We seek out information that supports us and downplay information that doesn’t. We get distracted by short-term emotions. When it comes to making choices, it seems, our brains are flawed instruments. Unfortunately, merely being aware of these shortcomings doesn’t fix the problem, any more than knowing that we are nearsighted helps us to see. The real question is: How can we do better? In Decisive, the Heaths, based on an exhaustive study of the decision-making literature, introduce a four-step process designed to counteract these biases. Written in an engaging and compulsively readable style, Decisive takes readers on an unforgettable journey, from a rock star’s ingenious decision-making trick to a CEO’s disastrous acquisition, to a single question that can often resolve thorny personal decisions. Along the way, we learn the answers to critical questions like these: How can we stop the cycle of agonizing over our decisions? How can we make group decisions without destructive politics? And how can we ensure that we don’t overlook precious opportunities to change our course? Decisive is the Heath brothers’ most powerful—and important—book yet, offering fresh strategies and practical tools enabling us to make better choices. Because the right decision, at the right moment, can make all the difference.
