Yale professor challenges Microsoft “Bing it On” claims

Do you remember those “Bing it On” ads? Microsoft ran advertisements that claimed a pool of 1,000 users “preferred Bing 2 to 1,” and allowed users to try it themselves with BingItOn.com. Yale professor Ian Ayers decided to duplicate the study, with BingItOn.com and Amazon’s Mechanical Turk. Detailing his study on the Freakonomics blog, Ayers said that Google’s results actually outranked Bing’s 53 percent to 41 percent, on average, but became more equal (48 percent preferring Google to 47 percent Bing) when Bing-suggested terms were involved.
