Venn diagrams were conceived around 1880 by John Venn. They are used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics, and computer science.
@BlueSkyKing The point wasn't about evidence (certainly regarding religion, the entire point is having a belief or innate feeling that something is true without, usually, substantial evidence) but about ways of interacting with or understanding the world that makes sense to people in various ways speaking to the metaphysical side of being human. And it's probably harmful to take all those non-material things away by calling them nonsense. (Not attacking you so much as the pic btw lol)
