Call for a moratorium on the use of the Rorschach Inkblot Test in clinical and forensic settings.

Résumé

A call is issued for a moratorium on the use of the Rorschach Inkblot Test in clinical and forensic (but not research) settings. The moratorium should last until we have determined which Rorschach scores are valid and which ones are invalid. Unfortunately, for most Rorschach scores, results from meta-analyses have been uninformative. Also, incremental validity has not been studied for most Rorschach scores. Furthermore, positive findings for Rorschach scores have rarely been independently replicated. Finally, selective reporting of results has been a problem: Some investigators report significant results but not nonsignificant results. The magnitude of this problem has not been determined. Unless a moratorium is adopted, clinicians will continue to interpret invalid scores along with valid scores.
