Sybil Exposed makes the case that the 1973 book Sybil misrepresents the facts of Shirley Mason’s life, diagnosis, and treatment. It also points to concerns that extend beyond a single case, to the diagnostic concept of multiple personalities. Still, perhaps the books suggests the need for a more systematic look at not just the case of Sybil, but also the diagnosis of dissociative identity disorder (DID).
