In 2007 Tim Harford established himself as the Undercover Economist, with a book of the same name. Now he’s back with a new book, Adapt: Why Success Always Starts with Failure, suggesting that in a multi-polar and interconnected world, we cannot tackle challenges with ready-made solutions and expert opinions. Instead, we must adapt. Harford argues for the importance of adaptive trial and error in tackling issues such as climate change, poverty and financial crises, as well as in fostering innovation and creativity in our business and personal lives.
