There are groups of people (you need a group, one alone would just look crazy) who believe in large, powerful, and yet perfectly secret (in the sense that no one can find evidence sufficient to convince the general public). Sometimes, these groups are confronted with news that makes their beliefs clearly wrong.
Examples:
Jehovah's Witness founder predicted the end of the world, several times. Spoiler alert, it didn't end. Yet there are millions of Jehovah's Witnesses.
The guy on "Behind the Curve" who got a ring laser gyroscope and watched it precess by 15 degrees per hour, even after he put it in a Faraday cage. Yet there remain FEs.
Q predicted that Trump was working with Mueller to bring down the democrat/hollywood pedophile/cannibal ring, and that a storm would happen, democrats arrested and Trump remaining president. To my knowledge, Q never made a successful prediction, nor was there any evidence that any prediction was ever true nor that Q was actually who he said he was.
What is this system of thinking where you become convinced of something, see real world evidence that it is not true, and yet insist ever more emphatically that it is still true?
Given this testament to faith, and the explanatory powers of changing the laws of physics and giant, multi-generational, yet perfectly secret conspiracies, is there any idea that can be disproven?
I have been warned about off topic posting. I will be watching for that on this thread, as my only question, the OP topic, is: "How can groups of people maintain faith with valid evidence against and none for?"
