You know, that's really interesting. The "revolutionary" mental model would offer a way of explaining all sorts of dissociative phenomena, like dissociative fugue, and dissociative identity. Basically, the brain would be triggering the "revolutionary" to escape from a traumatic reality, not to escape from a false belief. In the case of dissociative fugue, it seems the revolutionary removes your old memory and identity and lets the "apologist" defend your new identity.

It would be interesting to know if dissociative anesthetics can trigger the same kind mind changes as the revolutionary. From what I can tell, it sounds like they can.
