“This is a brilliant and fascinating book—Harford’s range of research is both impressive and inspiring, and his conclusions are provocative. The message about the need to accept failure has important implications, not just for policy making but also for people’s professional and personal lives. It should be required reading for anyone serving in government, working at a company, trying to build a career or simply trying to navigate an increasingly complex world.”
      —Gillian Tett, author of Fool’s Gold: The Inside Story of J.P. Morgan and How Wall St. Greed Corrupted Its Bold Dream and Created a Financial Catastrophe

“Harford’s wide-ranging look at social adaptation is fresh, creative, and timely.”
      —Sheena Iyengar, author of The Art of Choosing

“Adapt is a highly readable, even entertaining, argument against top-down design. It debunks the Soviet-Harvard command-and-control style of planning and approach to economic policies and regulations and vindicates trial and error (particularly the error part) as a means to economic and general progress. Very impressive!”
