Same anon about superstition tumblr. A very common thing I’ve seen there is people keep talking about “spirit work” and communicating with spirits. Some go very very far about it such as one who described their spirits as vampiric energy-sucking entities that can hurt other people if not monitored. Some also have gotten into the business of vetting and selling spirits. Some have formed very wild and detailed descriptions on them and how they work. How does something like this persist?
i’d say it is essentially the same mechanism as used by religion: it is often a comibination of instrumentalising fears/wishes and logical failure (”you can not prove that vampires do not exist – therefore they exist”). unfortunately this works pretty well for gullible minds. the greater the fear/wish of something to be true, the lesser people question it and ask for evidence and the more people are likely to fall for such a scam. just look at how religions have perfected this method with the concept of heaven and hell
