I think that this is the thing that rubs me the wrong way about CBT. I think it is all fine to investigate where an idea comes from, but the fact that you can just change or learn new beliefs as a way of undoing trauma is completely puzzling to me. I think that I just see what CBT therapists call beliefs as painful emotions that have to be worked though that are attached to the trauma. I don't really see the belief as some flexible thing that therapy can target. Beliefs to me are things that are constantly being reinforced by the outside world, and are something that people will always internalize and struggle with. To me it is about recognizing where the belief is coming from and what purposes it serves. This to me offers away of diffusing the belief, but I don't think that it will ever go away, or that it can simply be replaced with a new idea. But I do think you can find ways to push back against it or argue with it, rather than simply accepting it. Maybe I'm splitting hairs here, but there does seem to be an important distinction to me.
