The latest research on how fake news spreads on social media. Tl;dr, it’s pretty grim, although I think maybe the take-home is for all of us to start focusing more on “good reblog hygiene”, i.e. thinking before we reflexively reblog things that tug at our emotions, particularly emotions like vindication or outrage.
Also, personal quibble: journalists need to stop calling psyops units that intentionally spread disinformation propaganda “bots”. A bot is, like, all those _ebooks Markov chain accounts, or that electric eel’s account. A bot is not a dude who’s paid by a government agency (and/or shell company) to pose as a foreign citizen for the intent of infiltrating and undermining a political movement. That distinction matters.
