I think there's a state of mind associated with stuff like this where you just feel bad and you don't even want to know why anymore, you just want the bad feeling to stop? So it's not really based on evidence. I think there are some brain states that might be built out of confirmation bias and bad reasoning, but sometimes the only way to flush them and make your brain work again is to just move out of the surroundings that caused the badness in the first place.
