Trial, error and the God complex Tim Harford on

The third TEDTalk posted from TEDGlobal 2011, happening now in Edinburgh:

Economics writer Tim Harford studies complex systems — and finds a surprising link among the successful ones: they were built through trial and error. In this sparkling talk from TEDGlobal 2011, he asks us to embrace our randomness and start making better mistakes. (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland. Duration: 18:07)
