The "all-or-none error" in the DSM diagnostic system implies that a person either has or does not have a personality disorder, with no in-between or partial diagnoses. This dichotomous approach to diagnosis is a limitation of the DSM system, as it does not account for the varying degrees of severity and complexity that may be present in personality disorders.
