N2 - The Comprehensive System for the Rorschach (RCS) is currently the subject of intense scientific criticism. The normative data for many RCS scores are seriously in error and tend to make normal individuals appear maladjusted. Reliability is inadequate for many RCS scores, and validity for the great majority of RCS scores has not been adequately demonstrated. In addition, a substantial number of Rorschach Workshops studies, cited by B. Ritzier, R. Erard, and G. Pettigrevv (2002) as supportive of the RCS, are unavailable for examination. Finally, B. Ritzler et al. misinterpret central issues of the relevant legal analysis, including crucial legal standards. The RCS clearly fails to meet the standards for admissibility set forth in the Dauben, Joiner, and Kumho decisions.
