A Facebook newsfeed that was completely dictated by algorithms without human interference wouldn't be any better. Algorithms reflect the imperfect biases of the humans that build them. Algorithms rely on data sets, which are structured by the decisions of data gatherers guided by particular goals. For example, as most of the people who work in computing are male, it's not surprising that scholars found a gender bias in the Google's Image search: In searches for C.E.O., 11 percent of the people depicted were women, compared with 27 percent of U.S. C.E.O.s who are actually women.
