Flat Earth Movement

The modern flat earth movement has gained over 2 million online followers despite centuries of evidence against its core claim, ranking it as the most viral pseudoscience on this list. A 2023 survey found that 73% of followers cite distrust of government institutions as their reason for belief, and the movement's conspiracy theories are 50% more shared on social media than fact-based content. Unlike crystal healing's direct physical claims, flat earth's grander deception exploits a broader psychological vulnerability, but neither meets basic scientific standards.
