Hoax and reality

Multiple Personality Disorder (MPD) has become a fad. It was once so uncommon that investigators had discovered barely 200 cases by 1980. No longer. After that year, the number of cases exploded as therapist after therapist began to report seeing dozens, scores, hundreds of MPD patients. However, Dr. August Piper asserts that the surge in MPD cases is largely generated by the doctors themselves, by their over-inclusive diagnostic criteria and self-fulfilling therapeutic techniques.
