I recall reading something about fake news and propaganda some decades ago. Can’t recall the source book but it goes like this:
If one person tells you something absolutely outrageous you won’t believe it. If a second person tells you the same story you will stop and wonder. If a third person, preferably someone you respect, tells you the same you will have no doubts about the story at all.
I have no idea how true this is but if two more people tell you the same thing…
