Schizophrenia is also conflated with dissociative identity disorder, more commonly known as multiple personality disorder, due to the vernacular use of “split personality” to refer to a disorder unrelated to fractured personalities. And though psychosis is a phenomenon shared by disorders other than schizophrenia, the words “psycho” and “psychotic” are used to refer to everything from obnoxious ex-girlfriends to bloodthirsty serial killers.
