СКАЧАТЬ that people don’t always exercise good judgment while driving, so they build vehicles and roads with an eye to preserving drivers’ and passengers’ safety. Automobile designers and engineers try to compensate for our limited human ability by installing seat belts, antilock brakes, rearview mirrors, air bags, halogen lights, distance sensors, and more. Similarly, road designers put safety margins along the edge of the highway, some festooned with cuts that make a brrrrrr sound when you drive on them. But despite all these safety precautions, human beings persist in making all kinds of errors while driving (including drinking and texting), suffering accidents, injuries, and even death as a result.

      Now think about the implosion of Wall Street in 2008 and its attendant impact on the economy. Given our human foibles, why on earth would we think we don’t need to take any external measures to try to prevent or deal with systematic errors of judgment in the man-made financial markets? Why not create safety measures to help keep someone who is managing billions of dollars, and leveraging this investment, from making incredibly expensive mistakes?

      

      EXACERBATING THE BASIC problem of human error are technological developments that are, in principle, very useful but that can also make it more difficult for us to behave in a way that truly maximizes our interests. Consider the cell phone, for example. It’s a handy gadget that lets you not only call but also text and e-mail your friends. If you text while walking, you might look at your phone instead of the sidewalk and risk running into a pole or another person. This would be embarrassing but hardly fatal. Allowing your attention to drift while walking is not so bad; but add a car to the equation, and you have a recipe for disaster.

      Likewise, think about how technological developments in agriculture have contributed to the obesity epidemic. Thousands of years ago, as we burned calories hunting and foraging on the plains and in the jungles, we needed to store every possible ounce of energy. Every time we found food containing fat or sugar, we stopped and consumed as much of it as we could. Moreover, nature gave us a handy internal mechanism: a lag of about twenty minutes between the time when we’d actually consumed enough calories and the time when we felt we had enough to eat. That allowed us to build up a little fat, which came in handy if we later failed to bring down a deer.

      Now jump forward a few thousand years. In industrialized countries, we spend most of our waking time sitting in chairs and staring at screens rather than chasing after animals. Instead of planting, tending, and harvesting corn and soy ourselves, we have commercial agriculture do it for us. Food producers turn the corn into sugary, fattening stuff, which we then buy from fast-food restaurants and supermarkets. In this Dunkin’ Donuts world, our love of sugar and fat allows us to quickly consume thousands of calories. And after we have scarfed down a bacon, egg, and cheese breakfast bagel, the twenty-minute lag time between having eaten enough and realizing that we’re stuffed allows us to add even more calories in the form of a sweetened coffee drink and a half-dozen powdered-sugar donut holes.

      Essentially, the mechanisms we developed during our early evolutionary years might have made perfect sense in our distant past. But given the mismatch between the speed of technological development and human evolution, the same instincts and abilities that once helped us now often stand in our way. Bad decision-making behaviors that manifested themselves as mere nuisances in earlier centuries can now severely affect our lives in crucial ways.

      When the designers of modern technologies don’t understand our fallibility, they design new and improved systems for stock markets, insurance, education, agriculture, or health care that don’t take our limitations into account (I like the term “human-incompatible technologies,” and they are everywhere). As a consequence, we inevitably end up making mistakes and sometimes fail magnificently.

      

      THIS PERSPECTIVE OF human nature may seem a bit depressing on the surface, but it doesn’t have to be. Behavioral economists want to understand human frailty and to find more compassionate, realistic, and effective ways for people to avoid temptation, exert more self-control, and ultimately reach their long-term goals. As a society, it’s extremely beneficial to understand how and when we fail and to design/ invent/create new ways to overcome our mistakes. As we gain some understanding about what really drives our behaviors and what steers us astray—from business decisions about bonuses and motivation to the most personal aspects of life such as dating and happiness—we can gain control over our money, relationships, resources, safety, and health, both as individuals and as a society.

      This is the real goal of behavioral economics: to try to understand the way we really operate so that we can more readily observe our biases, be more aware of their influences on us, and hopefully make better decisions. Although I can’t imagine that we will ever become perfect decision makers, I do believe that an improved understanding of the multiple irrational forces that influence us could be a useful first step toward making better decisions. And we don’t have to stop there. Inventors, companies, and policy makers can take the additional steps to redesign our working and living environments in ways that are naturally more compatible with what we can and cannot do.

      In the end, this is what behavioral economics is about—figuring out the hidden forces that shape our decisions, across many different domains, and finding solutions to common problems that affect our personal, business, and public lives.

      

      AS YOU WILL see in the pages ahead, each chapter in this book is based on experiments I carried out over the years with some terrific colleagues (at the end of the book, I have included short biographies of my wonderful collaborators). In each of these chapters, I’ve tried to shed some light on a few of the biases that plague our decisions across many different domains, from the workplace to personal happiness.

      Why, you may ask, do my colleagues and I put so much time, money, and energy into experiments? For social scientists, experiments are like microscopes or strobe lights, magnifying and illuminating the complex, multiple forces that simultaneously exert their influences on us. They help us slow human behavior to a frame-by-frame narration of events, isolate individual forces, and examine them carefully and in more detail. They let us test directly and unambiguously what makes human beings tick and provide a deeper understanding of the features and nuances of our own biases.^*

      There is one other point I want to emphasize: if the lessons learned in any experiment were limited to the constrained environment of that particular study, their value would be limited. Instead, I invite you to think about experiments as an illustration of general principles, providing insight into how we think and how we make decisions in life’s various situations. My hope is that once you understand the way our human nature truly operates, you can decide how to apply that knowledge to your professional and personal life.

      In each chapter I have also tried to extrapolate some possible implications for life, business, and public policy—focusing on what we can do to overcome our irrational blind spots. Of course, the implications I have sketched are only partial. To get real value from this book and from social science in general, it is important that you, the reader, spend some time thinking about how the principles of human behavior apply to your life and consider what you might do differently, given your new understanding of human nature. That is where the real adventure lies.

      

      READERS FAMILIAR WITH Predictably Irrational might want to know how this book differs from its predecessor. In Predictably Irrational, we examined a number of biases that lead us—particularly as consumers—into making unwise decisions. The book you hold in your hands is different in three ways.

      First—and most obviously—this book differs in its title. Like its predecessor, it’s based on experiments that examine how we make decisions, but its take on irrationality is somewhat different. In most cases, the word “irrationality” has a negative СКАЧАТЬ
