This week on our Arbiters of Truth series on disinformation, Evelyn Douek and Quinta Jurecic spoke with Ben Collins and Brandy Zadrozny, reporters at NBC News. Writing at NBCNews.com, they report on disinformation and misinformation in health and politics. Their work covers a lot of ground, but for this episode, they discussed one increasingly prominent issue on that beat: QAnon, a conspiracy theory built around anonymous posts on an internet forum claiming that Donald Trump is waging war against a deep state and a vast network of child sex traffickers. The conspiracy theory has inspired acts of violence and is becoming increasingly mainstream, with several candidates for U.S. Congress being QAnon believers. They talked about how QAnon started, why we need to take it seriously and how the internet—and big technology platforms—have allowed the theory to spread.
