Greek, actually, the mythology around Cassandra, who was granted the power of seeing the future, yet was fated to never be believed. Or the Italian phrase, “traduttore, traditore”, which accurately describes the mindset we see here so often.That's actually an Aesop fable which has its moral explicitly stated to be, "Liars are rewarded with never being believed, even when they bring the truth.
"Tell them the truth, tell them a lie, it doesnt matter, they wont believe you anyway"
Cant argue or change a closed mind.
