Another great TED Talk. I'm reading Dan Ariely's Predicatably Irrational at the moment. It's great. It's a wonderful challenge to many conventional wisdoms. Here he tackles why our consistenly irrational behaviour reveals why traditional economic theory is often so wide of the mark. Really interesting to hear how permission to cheat is granted - and what that means for the stock market. FasterFuture is regularly updated by David Cushman
