A Scientific Critique of Rorschach Research

Abstract. Exner’s (1995a) Issues and Methods in Rorschach Research provided a standard of care for conducting Rorschach research; however, the extent to which studies have followed these guidelines has not been examined. Similarly, meta-analytic approaches have been used to comment on the validity of Exner’s Comprehensive System (CS) variables without an evaluation as to the extent that individual studies have conformed to the proposed methodological criteria ( Exner, 1995a ; Gacono, Loving, & Bodholdt, 2001 ). In this article, 210 studies cited in recent meta-analyses by Mihura, Meyer, Dumitrascu, and Bombel (2013) were examined. The studies were analyzed in terms of being research on the Rorschach versus research with the Rorschach and whether they met the threshold of validity/generalizability related to specific Rorschach criteria. Only 104 of the 210 (49.5%) studies were research on the Rorschach and none met all five Rorschach criteria assessed. Trends and the need for more stringent methods when conducting Rorschach research were presented.
