[P]eople are doomed to confirm their diagnosis regardless of how they react to the information they are given. If they accept the diagnosis, for instance, this constitutes their agreement, despite the fact that if they really do have the illness they are not supposed to be capable of having such awareness. Agreement also renders all of their other beliefs, ideas, and decisions suspect at best, as we still view schizophrenia as impairing their cognitive abilities and judgment. If, on the other hand, they deny the diagnosis, or refuse to accept it, this act can be used as evidence that the person lacks insight and therefore must have a mental illness. As a result, all of her beliefs, ideas, and decisions are similarly suspect, if not dismissed out of hand. Either way, the person is viewed as lacking the essential prerequisites for being a narrator of her own experience: awareness and insight.
