Martha Mitchell effect
Quoting psychotherapist Joseph Berke, the authors report that, "even paranoids have enemies". Delusions are "abnormal beliefs" and may be bizarre (considered impossible to be true), or non-bizarre (possible, but considered by the clinician as highly improbable). Beliefs about being poisoned, followed, having an unfaithful partner or a conspiracy in the workplace are examples of non-bizarre beliefs that may be considered delusions. Any patient can be misdiagnosed by clinicians, especially patients with a history of paranoid delusions.
