Brief overview

This book reveals why we often fall into predictable thinking traps and how we can avoid those pitfalls. You’ll discover the hidden mental shortcuts we use every day, and see how these shortcuts can distort our understanding of situations and lead us astray in our personal and professional lives.

Introduction

Have you ever made a decision that felt entirely logical at the time, only to look back and wonder how you could have believed it was the best choice? This is a natural part of human judgment, and a core theme of this book. We all like to think of ourselves as rational adults, but in truth, our brains rely on quick mental shortcuts that can lead us astray.

The chapters ahead illustrate how these thinking shortcuts—also called biases—direct everything from the products we buy to the relationships we maintain. Real-life anecdotes show us exactly how easily we can be fooled by what feels like an obvious truth. Understanding why this happens is the first step toward making better decisions.

Each page breaks down a different bias or misconception, providing practical examples and guiding you to spot these errors in your own life. You don’t need to become an emotionless robot; rather, the goal is to see how your feelings and assumptions can unconsciously shape your actions and how to steer them more consciously.

We Are More Irrational Than We Think

It’s easy to assume we operate by logic, but countless experiments show otherwise. From small things—like leaving a tip at a free coat check—to larger investments involving significant sums of money, our decisions are often driven by social pressures and perceptions rather than pure reasoning.

An illustration is the so-called 'Bay of Pigs' fiasco. Even some of the brightest advisors went along with an obviously flawed plan, simply because their desire to fit in exceeded their desire to question authority. This story serves as a dramatic reminder that intelligence alone doesn’t shield anyone from errors in thinking.

Being slightly irrational is not a weakness; it’s the way we’re wired. But if we stay unaware of these mental blind spots, we’ll keep stumbling for the same reasons. Recognizing our hidden bias is already a big leap toward clearer thinking. Greater self-awareness lets us step back, reflect, and choose more wisely.

Acknowledging irrationality is the gateway to making meaningful changes in how you decide and act.
