Not really. Like, almost all conspiracy theories rely on trusting unverified accounts from strangers. Someone who believes in Qanon, for example, is implicitly trusting an anonymous voice on 4chan, treating them as totally reputable without any kind of proof.

Conspiracy theories spread because it's appealing to think you know more than other people. A secret alternate history of the Kennedy assassination or something that suggests that your political opponents are being manipulated by shadowy forces will make the people who believe it feel like they're better than other people, and so they'll trust it without question.
