In a new episode of Lawfare's Arbiters of Truth series on disinformation in the run-up to the 2020 election, Quinta Jurecic, Evelyn Douek, and Alina Polyakova, spoke with Ben Nimmo, the director of investigations at Graphika. They talked about how disinformation works; how a researcher knows where to look to find disinformation; how to tell when a strange pattern of tweets or Facebook posts is actually a disinformation campaign; and whether it's possible to counter these campaigns effectively, or if this work is just a never-ending game of whack-a-mole.
