Other journalists and researchers have expressed concerns similar to Epstein's. Safiya Noble cited Epstein's research about search engine bias in her 2018 book "Algorithms of Oppression", although she has expressed doubt that search engines ought to counter-balance the content of large, well-resourced and highly trained newsrooms with what she called "disinformation sites" and "propaganda outlets". Ramesh Srinivasan, a professor of information studies at UCLA focusing on "the relationships between technology and politics", agreed with Epstein that "the larger issue" of how search engines can shape users' views is "extremely important", but questioned how many undecided voters are using Google to help them decide whom to vote for.
