A case of simulated fragmentation

The New York Times has an excerpt of a book that claims to expose one of the most famous psychiatric cases in popular culture as a fraud.
Based on an analysis of previously locked archives the book suggests that the patient at the centre of the ‘Sybil’ case of ‘multiple personality disorder’ was, in fact, faking and admitted so to her psychiatrist.
The diagnosis, now named dissociative identity disorder, is controversial because the idea that someone can genuinely have several ‘personalities’ inside a single body has not been well verified and diagnoses seemed to boom after the concept became well-known.
This particular case became well known because it was written up as a best-selling 1973 book and was later turned into successful film of the same name.
The book and the film are though to have been key in the shaping the concept of the diagnosis and making it popular during the late 70s and 80s.
However, detective work by author Debbie Nathan has seemed to uncover medical notes that suggest the psychiatrist at the centre of the case, Cornelia Wilbur, may have known that his patient had admitted to faking for some time.
One may afternoon in 1958, Mason walked into Wilbur’s office carrying a typed letter that ran to four pages. It began with Mason admitting that she was “none of the things I have pretended to be.
“I am not going to tell you there isn’t anything wrong,” the letter continued. “But it is not what I have led you to believe. . . . I do not have any multiple personalities. . . . I do not even have a ‘double.’ . . . I am all of them. I have been essentially lying.”
Before coming to New York, she wrote, she never pretended to have multiple personalities. As for her tales about “fugue” trips to Philadelphia, they were lies, too. Mason knew she had a problem. She “very, very, very much” wanted Wilbur’s help. To identify her real trouble and deal with it honestly, Mason wrote, she and Wilbur needed to stop demonizing her mother. It was true that she had been anxious and overly protective. But the “extreme things” — the rapes with the flashlights and bottles — were as fictional as the soap operas that she and her mother listened to on the radio. Her descriptions of gothic tortures “just sort of rolled out from somewhere, and once I had started and found you were interested, I continued. . . . Under pentothal,” Mason added, “I am much more original.”
