->''"Sometimes improbable patient reports are erroneously assumed to be symptoms of mental illness. The ‘Martha Mitchell effect’ referred to the tendency of mental health practitioners not to believe the experience of the wife of the American attorney general, whose persistent reports of corruption in the [[UsefulNotes/RichardNixon Nixon]] White House were initially dismissed as evidence of delusional thinking, until later proved correct by the Watergate investigation. Such examples demonstrate that delusional pathology can often lie in the failure or inability to verify whether the events have actually taken place, no matter how improbable intuitively they might appear to the busy clinician. Clearly, there are instances ‘where people are pursued by the Mafia’ or are ‘kept under surveillance by the police’, and where they rightly suspect ‘that their spouse is unfaithful’. As Joseph H. Berke wrote, even paranoids have enemies! For understandable and obvious reasons, however, little effort is invested by clinicians into checking the validity of claims of persecution or harassment, and without such evidence the patient could be labelled delusional."''
