" The story of Sybil is true, not fictional or fraudulent. One early commentator actually suggested that Sybil and Dr. Cornelia Wilbur, her treating psychiatrist, were a case of folie à deux, or shared psychosis (Victor, 1975). Having met Dr. Wilbur, listened to her presentations on multiple personality (now known as dissociative identity disorder), and read the many critiques and reviews of Sybil, I have concluded that Sybil was not iatrogenically created by Dr. Wilbur.
