The Walrus wants you to be scared of TikTok misinformation
https://thewalrus.ca/social-media-is-warping-history/ which seems to draw on a trade book from a Big Five publisher: Jason Steinhauer,
History, Disrupted: How Social Media and the World Wide Web Have Changed the Past (Palgrave Macmillan, 2022)
Basically though, corporate social media are not places for establishing evidence-based consensus. They never were, any more than bar-room chats, cable TV, or magazines for thinky talky people were. If you wanted them to be, you would build them differently, and they would be much smaller. Knowing verifiable true things is an uncommon taste. There was no time in the 20th century when most people in the North Atlantic world were good scientific materialists, most people have at least one belief or practice which is hard to square with natural science. But when you are one-on-one or one-on-few with people, you can listen with attention, ask some gentle questions, and offer some extra information and often they can take that and step away from the woo.
If you want a mass-media-sized audience, you have to create mass-media-shaped things like big speculative claims or moralistic gossip about famous people.
