"If we understand how conspiracy theories spread online, we can help stop them. Millions of people have watched an online video that recycled discredited health conspiracies into what looked like a slick documentary about the coronavirus and vaccines.The success of the video, part of a documentary called “Plandemic,” has crystallized everything terrible about the internet. People pushing a baseless conspiracy used extreme online savvy to unleash a misinformation goulash, the internet companies couldn’t do enough to prevent its spread, and we ate it up.This happens again and again. But we can help stop it."
