From the Pulitzer Prize-winning journalist and author of Why We Make Mistakes, an illuminating exploration of human beings’ astonishing ability to deceive themselves. To one degree or another, we all misjudge reality. Our perception-of ourselves and the world around us-is much more malleable than we realize. This self-deception influences every major aspect of our personal and social life, including relationships, sex, politics, careers, and health. In Kidding Ourselves, Joseph Hallinan offers a nuts-and-bolts look at how this penchant shapes our everyday lives, from the medicines we take to the decisions we make. It shows, for instance, just how much the power of many modern medicines, particularly anti-depressants and painkillers, is largely in our heads. Placebos in modern-day life extend beyond hospitals, to fake thermostats and “elevator close” buttons that don’t really workbut give the perception that they do. Kidding Ourselves brings together a variety of subjects, linking seemingly unrelated ideas in fascinating and unexpected ways. And ultimately, it shows that deceiving ourselves is not always negative or foolish. As increasing numbers of researchers are discovering, it can be incredibly useful, providing us with the resilience we need to persevere, in the boardroom, bedroom, and beyond. Provocative, accessible, and easily applicable to multiple facets of everyday life, Kidding Ourselves is an extraordinary new exploration of our mind’s flexibility.

We forget our passwords. We pay too much to go to the gym. We think we’d be happier if we lived in California (we wouldn’t), and we think we should stick with our first answer on tests (we shouldn’t). Why do we make mistakes? And could we do a little better?

We human beings have design flaws. Our eyes play tricks on us, our stories change in the retelling, and most of us are fairly sure we’re way above average. In Why We Make Mistakes, journalist Joseph T. Hallinan sets out to explore the captivating science of human error—how we think, see, remember, and forget, and how this sets us up for wholly irresistible mistakes.

In his quest to understand our imperfections, Hallinan delves into psychology, neuroscience, and economics, with forays into aviation, consumer behavior, geography, football, stock picking, and more. He discovers that some of the same qualities that make us efficient also make us error prone. We learn to move rapidly through the world, quickly recognizing patterns—but overlooking details. Which is why thirteen-year-old boys discover errors that NASA scientists miss—and why you can’t find the beer in your refrigerator.

Why We Make Mistakes is enlivened by real-life stories—of weathermen whose predictions are uncannily accurate and a witness who sent an innocent man to jail—and offers valuable advice, such as how to remember where you’ve hidden something important. You’ll learn why multitasking is a bad idea, why men make errors women don’t, and why most people think San Diego is west of Reno (it’s not).

Why We Make Mistakes will open your eyes to the reasons behind your mistakes—and have you vowing to do better the next time.
