**Who This Book Is For:**

This book is for anyone who has ever felt overwhelmed by too much stuff, too many commitments, too much information, or too much complexity. It is for designers, leaders, parents, educators, and anyone who wants to make things better but suspects that adding more is not always the answer. If you have ever wondered why we keep building, buying, and accumulating when less might serve us better, this book will change how you see the world.

Consider a simple question: When you want to improve something, what is your first instinct? For most people, the answer is to add. Add more features to a product. Add more items to a to-do list. Add more words to an explanation. Add more rooms to a house. Add more activities to a vacation. The impulse is so natural that we rarely pause to consider the alternative. But what if the best improvement is not adding something new, but removing something that already exists? Leidy Klotz stumbled onto this question through a playful moment with his young son. The two were building a Lego bridge together, and the structure was uneven. One pillar was taller than the other. Klotz, like most adults, reached for another block to add to the shorter pillar. Before he could, his son simply removed a block from the taller pillar. The bridge became level. The problem was solved. Nothing was added, and yet the outcome was better. That moment sparked a research program that would span years and involve collaborators across multiple disciplines. Klotz wanted to know: Was his son's subtractive solution unusual? Do humans systematically overlook subtraction as a way to improve situations? And if so, why? The answer, it turns out, is yes. Across dozens of experiments, Klotz and his colleagues found that people overwhelmingly default to addition. When asked to improve a piece of writing, they add words. When asked to improve a travel itinerary, they add destinations. When asked to improve a Lego structure, they add blocks. Even when subtraction would be faster, cheaper, and more effective, people still tend to add. This bias is not just a quirk of individual behavior. It shapes our institutions, our economies, our cities, and our planet. We measure progress by growth. We reward accumulation.…
