The Art of Thinking Clearly is a practical guide that delves into the common cognitive biases and mental errors that shape our thinking and decision-making processes. Rolf Dobelli, drawing on insights from psychology, behavioral economics, and philosophy, presents 99 short chapters, each focusing on a specific bias or logical fallacy. The book emphasizes how these biases, often unconscious, can lead to poor decisions in everyday life, affecting everything from personal relationships to business choices. Dobelli illustrates these biases with real-world examples, making the concepts relatable and easy to understand. For instance, he explains how we tend to overvalue our own opinions (the "illusion of control") or how we often make decisions based on emotions rather than rational thought (the "affect heuristic").
