**Who This Book Is For:**

Anyone who has ever felt stuck in a decision, overwhelmed by complexity, or curious about how successful people structure their thinking. Whether you are leading a team, navigating a career change, or simply trying to understand why you keep making the same mistakes, this book gives you a toolkit for clearer thought.

Every day, you make thousands of decisions. Most are small. What to eat. What to wear. Which email to answer first. But some are large. Should I quit my job? Is this relationship working? How do I lead my team through a crisis? What should I do with my life? The strange thing is that most of us approach both small and large decisions the same way: we rely on intuition, habit, or the advice of whoever happens to be nearby. We rarely pause to consider how we are thinking. We rarely ask whether there is a better way to structure the problem in front of us. This is where models come in. A model is not a rule. It is not a formula that tells you what to do. A model is a tool for thinking. It simplifies a complex situation by focusing your attention on the variables that matter most. It gives you a framework for organizing information, identifying patterns, and generating insights that might otherwise remain invisible. Mikael Krogerus and Roman Tschäppeler created The Decision Book to collect fifty of the most useful models from psychology, economics, management, and philosophy. The book is deliberately small. Each model gets just a few pages. But the cumulative effect is powerful: by the end, you have a mental toolkit that you can apply to almost any situation. The key insight of the book is simple but profound. Models do not define what or how you should think. They are the result of an active thought process. A model is not a substitute for thinking. It is a starting point for thinking more clearly. This matters because the world is becoming more complex, not less. The amount of information available to us doubles every few years. The number of decisions we face each day has multiplied. The consequences of those decisions ripple outward in ways we cannot always predict. Without tools for managing this complexity, we become overwhelmed. We default to reactive thinking. We confuse urgency with importance. We repeat the same mistakes. The models in this book offer an alternative. They give you…
