"In this groundbreaking book, Tim Harford shows us a new and inspiring approach to solving the most pressing problems in our lives. Harford argues that today's challenges simply cannot be tackled with ready-made solutions and expert opinions; the world has become far too unpredictable and profoundly complex. Instead, we must adapt-improvise rather than plan, work from the bottom up rather than the top down, and take baby steps rather than great leaps forward. "
