"You need to read this book." âAdam Grant, #1 New York Times bestselling author âA great book changes the world you live in, revealing mysteries you didn't even know were there. This is a great book." âSendhil Mullainathan, MacArthur fellow and author of Scarcity Blending behavioral science and design, Leidy Klotz's Subtract offers a scientific appreciation of why we underuse subtractionâand how to access its untapped potential. We pile on âto-dosâ but donât consider âstop-doings.â We create incentives for good behavior, but donât get rid of obstacles to it. We collect new-and-improved ideas, but donât prune the outdated ones. Every day, across challenges big and small, we neglect a basic way to make things better: we donât subtract. Klotzâs pioneering research shows us what is true whether weâre building Lego models, cities, grilled-cheese sandwiches, or strategic plans: Our minds tend to add before taking away, and this is holding us back. But we have a choiceâour blind spot need not go on taking its toll. Subtract arms us with the science of less and empowers us to revolutionize our day-to-day lives and shift how we move through the world. More or less.
