Johnson -- writer, Web guru, and bestselling author -- delivers a sweeping look at innovation spanning nearly the whole of human history. What sparks our great ideas? Johnson breaks down the cultural, biological, and environmental fuel into seven broad "patterns," each packed with diverse anecdotes that Johnson synthesizes into a recipe for success. A section on "slow hunches" captivates, taking readers from the FBI's work on 9/11 to Google's development of Google News. A section on error takes us through a litany of accidental innovations, including the one that eventually led to the invention of the computer. "Being right keeps you in place," Johnson reminds us. "Being wrong forces us to explore." It's eye-opening stuff -- although it does require an investment from the reader. But as fans of the author's previous work know, an investment in Johnson pays off, and those who stick with the author as he meanders through an occasional intellectual digression will come away enlightened and entertained, and with something perhaps even more useful--how to recognize the conditions that could spark their own creativity and innovation.
