The Reliability of the Comprehensive System for the Rorschach: A Comment on Meyer (1997)

Elsewhere the authors have called attention to fundamental problems with the Comprehensive System for the Rorschach (CS). G. Meyer (1997) attempts to refute the authors' criticisms of CS interrater reliability, but misrepresents what they actually stated, and several of his arguments are based on psychometric errors and misunderstandings. The meta-analysis in Meyer's article is flawed and fails to demonstrate CS interrater reliability. Instead of defending the CS with unsound arguments and shaky numbers, Rorschach proponents need to accept valid criticisms and undertake high-quality, replicated studies of reliability and validity.
