Why Do Delusions Persist?

You might like this article. So one thing I will say is that the predicted outcome of a delusion never has to even happen and usually it's something secret, and often something that can't be easily proven either way or even provided for exposure. For example if I think I'm receiving psychic communications from other scientists but we aren't allowed to talk about it because it would disrupt the world if they knew of our powers. How do you fix that? I mean in theory I would expect everyone to deny everything and only I can hear the voices. For me my delusions were like that they would simply become more elaborate if anything did register as odd about them.
