Book Excerpt: "The Art of Thinking Clearly" by Rolf Dobelli 
 Introduction 
 The human mind is capable of incredible feats, yet it has surprising limitations. We often fall into thinking traps that lead us to make poor decisions, based on flawed assumptions or incomplete information. These traps are so common that they have names: confirmation bias, hindsight bias, the sunk cost fallacy, and many others. In this book, I will explore these thinking traps and offer strategies for avoiding them. 
 Chapter 1: The Anchoring Effect 
Our minds are wired to use anchors - starting points - when making decisions. Once an anchor is set, we tend to adjust our thinking around it, even if it is arbitrary or irrelevant. For example, when negotiating a salary, the first number mentioned tends to become the anchor, even if it is not a reasonable figure. 
 Chapter 2: The Sunk Cost Fallacy 
 We often make the mistake of continuing to invest in a failing project, simply because we have already invested so much time, money, or effort. This is known as the sunk cost fallacy. We need to recognize when a project is unlikely to succeed and cut our losses, rather than throwing good money after bad. 
 Chapter 3: Confirmation Bias 
 We tend to seek out information that confirms our existing beliefs, and discount or ignore information that contradicts them. This is known as confirmation bias. To avoid this thinking trap, we need to actively seek out dissenting opinions and consider them with an open mind. 
 Chapter 4: The Halo Effect 
We often form an overall impression of a person or thing based on a single positive attribute, such as attractiveness or success. This is known as the halo effect. To avoid this thinking trap, we need to break down our judgments into smaller components and evaluate each one separately. 
 Chapter 5: Overconfidence 
We are often overly confident in our own abilities and judgments, leading us to take risks or make decisions that are not backed up by evidence. To avoid overconfidence, we need to seek out diverse perspectives and be willing to admit when we don't know something. 
 Conclusion
 The thinking traps explored in this book are just a few examples of the ways in which our minds can lead us astray. By recognizing these traps and using strategies to avoid them, we can make better decisions and lead more successful lives.
