This week we're bringing you the breakdown of the heavyweight bout of the century—a battle over vaccine misinformation. In the left corner we have the White House. Known for its impressive arsenal and bully pulpit, this week it asked for the fight and came out swinging with claims that Facebook is a killer—and not in a good way. In the right corner we have Facebook, known for its ability to just keep taking punches while continuing to grace our screens and rake in the cash. The company has hit back with gusto, saying that Facebook has actually helped people learn the facts on vaccines. Period. Will either of them land a knockout blow? Is this just the first round of many match ups? On this episode of our Arbiters of Truth series on our online information ecosystem, we devote the conversation to the latest slugfest between Facebook and the White House. Evelyn Douek and Quinta Jurecic spoke with Renee DiResta, the research manager at the Stanford Internet Observatory, and Brendan Nyhan, professor of government at Dartmouth University, both of whom have been working on questions of online health misinformation.
