At this point people can believe in whatever they want as long as it doesn't harm anyone else. Someone believing in a bunch of crystals and burning their money on them is a lot less harmful than other beliefs that I won't mention.
I think there are many societal harms that arise out of enabling and enriching the types of scammers that abuse hopeful yet naive people. But social science doesn't count.
Agreed. Crystals, manifestation, astrology etc. is such a stupid thing for people to feel mentally superior over others for. Being a jackass and bullying people for wanting to believe in something like luck is mentally weak. Science doesn't save a mind from its own ignorance.
