A new study has found racial bias in ad results from the online search engine Google. Harvard Professor Latanya Sweeney found names typically associated with African Americans were 25 percent more likely to produce ad results offering background checks and suggesting the person had a criminal record. Sweeney conducted the study after a search for her own name turned up an ad reading, “Latanya Sweeney, Arrested?” with a link offering background checks. Sweeney concluded: “There is discrimination in the delivery of these ads.”
