Creativity has become a buzzword, universally desirable but uniformly misunderstood. What is it, really? Is there a definition large enough to capture all the various activities that fall under its umbrella? And what can social scientists tell us about where it comes from and (more importantly) how to get more of it? I’m producing an ongoing series for Freakonomics Radio that asks these questions, featuring interviews with creative practitioners like Elvis Costello, Ai Weiwei, Tracy K. Smith, Jennifer Egan, Wynton Marsalis, John Hodgman, and many more. Listen to the whole series here.
