This week on Lawfare’s Arbiters of Truth series on disinformation, Evelyn Douek and Quinta Jurecic spoke with Bridget Barrett and Daniel Kreiss of the UNC Hussman School of Journalism and Media and UNC’s Center for Information, Technology, and Public Life. In all the controversy around social media platforms at the moment, perhaps nothing is taking up as much oxygen as their policies around political ads. But it’s difficult to discuss this topic without a detailed understanding of what the platforms are actually doing. That’s where Bridget and Daniel come in. They’ve worked to provide a comprehensive account of the different policies in this space, how those policies interact, and how they’re changing—or not—the way we interact with politics.
