This week on Arbiters of Truth, the Lawfare Podcast’s miniseries on our online information ecosystem, Evelyn Douek and Quinta Jurecic sat down with Brendan Nyhan to discuss the crucial platform that often seems to slip under the radar in discussions of mis- and disinformation: YouTube. Brendan is a professor of government at Dartmouth College, who has just co-authored a report with the Anti-Defamation League on “Exposure to Alternative and Extremist Content on YouTube.” There’s a common conception that YouTube acts as a radicalization engine, pushing viewers from mainstream content to increasingly radical material. But Brendan and his coauthors found a somewhat different story: YouTube may not funnel all viewers toward extreme content, but it does reliably recommend that content to users who are already viewing it. They discussed his findings and how we should understand the role that YouTube plays in the information ecosystem. See acast.com/privacy for privacy and opt-out information.
