I do not believe in multiple personalities. It is said to be a subtype of dissociative personality disorder. I don't see much scientific support for these "dissociative states, " either. Many criminal defendants use this d/o, for example, to try to get off on charges, as a form of temporary insanity. The idea of multiple personalities took off with the TV move Sybil. It is junk science. Thanks for your interest. In fact, it was good to solicit an explanation for being critical of a woman, where the press says she's 100% sympathetic. The fact that it is somehow "2500" personalities should make any thinking person think twice about believing it. It is like the fish that got away. Say there never was a fish at all. I might as well make that fish huge, if I want to make an impression.
