For 150 years, we've been taught that we had to choose sides when understanding where top-level performance comes from. Is it nature? Or, is it nurture? In this episode, two of our favorite guests of all time Dan Coyle—author of The Talent Code—and Dave Epstein—author of The Sports Gene—join us on the show to discuss what the latest science really shows about where talent comes from. Is it nature vs nurture or is it more accurate to say nature plus nurture? One of the mankind's most enduring questions. We think we can pretty much wrap it up in an hour. Well, maybe not wrap it up but with Dan Coyle and Dave Epstein onboard we can get about as close as humanly possible. You can follow them on Twitter at @DavidEpstein and @DanielCoyle. Their blogs are http://thesportsgene.com/blog/ and http://www.thetalentcode.com. The Sports Gene, The Talent Code and The Little Book of Talent are available from all good booksellers.
