The claims popped up in Google's "Popular on Twitter" module, which made them prominently visible — although not the top results — in a search for the alleged killer's name. Of course, the was just the latest instance of a long-standing problem: it was the latest of multiple similar missteps. As usual, Google promised to improve its search results, while the offending tweets disappeared. But telling Google to retrain its algorithms, as appropriate as that demand is, doesn't solve the bigger issue: the search engine's monopoly on truth.
Surveys suggest that, at least in theory, very few people unconditionally believe news from social media. But faith in search engines — a field long dominated by Google — appears consistently high. A 2017 Edelman survey found that 64 percent of respondents trusted search engines for news and information, a slight increase from the 61 percent who did in 2012, and notably more than the 57 percent who trusted traditional media. (Another 2012 survey, from Pew Research Center, found that 66 percent of people believed search engines were "fair and unbiased," almost the same proportion that did in 2005.) Researcher danah boyd has suggested that media literacy training conflated doing independent research with using search engines. Instead of learning to evaluate sources, "[students] heard that Google was trustworthy and Wikipedia was not."
