The Innovation Paradox: The Success of Failure, the Failure of Success (Free Press, $11) is the paperback edition of last year’s more boldly titled hardback, Whoever Makes the Most Mistakes Wins: The Paradox of Innovation. The new title seems to reflect a slight retrenchment on the main theme, since it downplays the need to make more mistakes than your rivals. One can only presume the publisher wants this book to succeed, despite its embrace of failure; hence, the new title. In any event, Farson and Keyes offer to teach you how to be more failure-tolerant and risk-friendly, “and therefore more innovative.”
