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 ground-breaking 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.
