Recently, a video called “Plandemic” went viral on social media. PolitiFact flagged eight fake or misleading claims it made about COVID-19. YouTube and Facebook removed the video; Twitter issued “unsafe” warnings and blocked relevant hashtags. All of the platforms couched their content moderation decisions in terms of the generic “violations of community standards” language, and expressed concerns that the video could cause “imminent harm” as Facebook put it.

Such swift, draconian decisions assume not just that the content is ricocheting around the internet—indeed, data on trending and sharing easily corroborate that—but that people remember and believe the it. Do they?
