People can be faced with a tsunami of facts and evidence on something, but if this conflicts with a cherished belief of theirs, they find a way to completely negate the facts. This isn’t a case of just filtering out evidence that clashes with their opinions. It’s a case of them being smacked upside the head with the evidence and consciously finding a way to invalidate it. No matter how much they have to contort, warp or totally flee from logic.
