This book reveals a remarkable paradox: what your brain wants is frequently not what your brain needs. In fact, much of what makes our brains "happy" leads to errors, biases, and distortions, which make getting out of our own way extremely difficult.
Author David DiSalvo presents evidence from evolutionary and social psychology, cognitive science, neurology, and even marketing and economics. And he interviews many of the top thinkers in psychology and neuroscience today. From this research-based platform, DiSalvo draws out insights that we can use to identify our brains' foibles and turn our awareness into edifying action. Ultimately, he argues, the research does not serve up ready-made answers, but provides us with actionable clues for overcoming the plight of our advanced brains and, consequently, living more fulfilled lives.

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.
