(stevehanov.ca) Submitted by itwbennett on Wednesday May 30, 2012 @04:53PM itwbennett writes: "In a blog post, Steve Hanov explains how 20 lines of code can outperform A/B testing. Using an example from one of his own sites, Hanov reports a green button outperformed orange and white buttons. Why don't people use this method? Because most don't understand or trust machine learning algorithms, mainstream tools don't support it, and maybe because bad design will sometimes win."
