People refuse to try to address that sort of wooly thinking when it is low stakes then when it becomes high stakes act shocked to see the people around them acting irrationally. One’s hypothetical friend who refused to take the vaccine because they thought it had a mind control chip in it and died as a result invariably was previously banging on about how their acupuncturist was going to help them win the lottery and people simply indulged them because “what’s the harm in them having funny beliefs about things?” The only time you actually could get through to people around you about these harmful ways of thinking is when it’s about things that don’t really matter much. If you wait until it’s life or death it’s too late to get though to them.
