> Delusional thinking is a dysfunctional process almost by definition, since it produces invalid conclusions. His point is that delusional thinking is _normal_ and almost all people have deeply held delusions of one kind or another. There is nothing about _any particular delusion_ which implies some kind of disorder, which implies the person lacks agency or any ability to be talked out of them. I think that is different that saying that there is no disorder which can give rise to delusions, only that having some particular delusional belief does not imply that you have such a disorder, necessarily.
