I understand what you are saying. Here is what I am saying. Say you wanted to prove to someone, who does not understand special realitivity, that light will red shift with velocity away from an observer. You can show them all tons of red shift data, which is proof enough for the experts. But since the person, we need to prove this to, does not understand the basics of special relativity so they can understand the proof, we can't prove anything to him even if it is true. The best we can do is manipulate his emotions, with a group hug, so he will memorize our claim. He still doesn't understand the proof. But he can recite the group hand-shake using faith in its experts. If he really wanted proof but was not willing or able to understand special reality, this gets harder to do. How can you prove special relativity to someone who doesn't even understand it. it all sounds like it is made up to him.
