“Parts Psychology” by Jay Noricks, PhD: “The idea that we all have multiple personalities, but not necessarily a disorder…may at first be shocking…”

Preface (1, pp. xi-xiii)

“The idea that we all have multiple personalities—but not [necessarily] a disorder of personalities—may at first be shocking. But the evidence for this normal multiplicity among relatively ordinary people is so powerful that even the most skeptical of readers may change their minds before finishing the book…

“Of course, some problems take many years to resolve, such as dissociative identity disorder (DID), previously labeled multiple personality disorder (MPD)…My purpose in excluding dissociative disorders is simply to avoid confusion. Otherwise it might be less clear that it is normal for people to have hidden parts of themselves…Over the last 10 years I have worked with more than 30 cases of DID and my caseload has included, at any given time, three to six clients with this diagnosis…” (1).

Comment: Multiple Personality is much more common than most people—including psychologists and psychiatrists—appreciate. Among psychiatrists who have most knowledge about multiple personality (a.k.a. dissociative identity), it is known as a disorder of “hiddenness,” except during a crisis or when the personalities are addressed by name. The regular or “host” personality often has a memory gap for the period of time that an alternate had taken over.
