“Other personalities are created to handle new traumas, their existence usually occurring one at a time. Each has a singular purpose and is totally focused on that task. The important aspect of the mind's extreme dissociation is that each ego state is totally without knowledge of the other. Because of this, the researchers for the CIA and the Department of Defense believed they could take a personality, train him or her to be a killer and no other ego stares would be aware of the violence that was taking place. The personality running the body would be genuinely unaware of the deaths another personality was causing. Even torture could not expose the with, because the personality experiencing the torture would have no awareness of the information being sought.
Earlier, such knowledge was gained from therapists working with adults who had multiple personalities. The earliest pioneers in the field, such as Dr. Ralph Alison, a psychiatrist then living in Santa Cruz, California, were helping victims of severe early childhood trauma. Because there were no protocols for treatment, the pioneers made careful notes, publishing their discoveries so other therapists would understand how to help these rare cases. By 1965, the information was fairly extensive, including the knowledge that only unusually intelligent children become multiple personalities and that sexual trauma endured by a restrained child under the age of seven is the most common way to induce hysteric dissociation.”
