Everything we know about solving the world's problems is wrong. Out: Plans, experts and above all, leaders. In: Adapting — improvise rather than plan; fail, learn, and try again In this groundbreaking new book, Tim Harford shows how the world's most complex and important problems — including terrorism, climate change, poverty, innovation, and the financial crisis — can only be solved from the bottom up by rapid experimenting and adapting. From a spaceport in the Mojave Desert to the street battles of Iraq, from a blazing offshore drilling rig to everyday decisions in our business and personal lives, this is a handbook for surviving — and prospering — in our complex and ever-shifting world.
