Sample Book Insights: #1 I had been trying to convert my interest in less into something I could study. From the start, I had studied ways that buildings and cities might use less energy, and produce fewer climate-changing emissions. I had homed in on the designers, finding that they use mental shortcuts. #2 I was able to bring many of the other parents up to speed by explaining to them that subtraction is a way to change things. They were initially confused, but eventually understood. #3 The three-to-one ratio was found when people were asked to change random musical notes, and when people were asked to improve a piece of writing. It was roughly the same three-to-one ratio when people were asked to transform a five-ingredient soup. #4 The Lego experiment showed that people overwhelmingly add more than they subtract. We then created a situation that would inspire subtraction, asking participants to improve an itinerary for a day in Washington, D. C. Only one in four participants removed activities from the packed original.
