bonch writes "Technology consultant Benjamin Edelman has developed a methodology for determining the existence of a hard-coded bias in Google's search engine which places Google's services at the top of the results page. Searching for a stock ticker places Google Finance at the top along with a price chart, but adding a comma to the end of the query removes the Google link completely. Other variations, such as 'a sore throat' instead of 'sore throat,' removes Google Health from its top position. Queries in other categories provide links to not only Google services but also their preferred partners. Though Google claims it does not bias its results, Edelman cites a 2007 admission from Google's Marissa Mayers that they placed Google Finance at the top of the results page, calling it 'only fair' because they made the search engine. Edelman notes that Google cites its use of unbiased algorithms to dismiss antitrust scrutiny, and he recalls the DOJ's intervention in airlines providing favorable results for their own flights in customer reservation systems they owned."
