The validity of judgments based on "blind" Rorschach records.

Abstract
Each of 20 clinicians experienced in the use of the Rorschach was given the "task of identifying five Rorschach protocols according to clinical group. The groups were: (a) Involutional depression; (b) paranoid schizophrenia; (c) anxiety neurosis; (d) brain damage due to syphilis; and (e) adult mental deficiency. The judges were told which five clinical groups were represented and that they would receive one Rorschach record from each group". Among the results of this phase of the study of "blind" analysis of the Rorschach were the following: "Out of 100 possible judgement, clinicians were correct 58 times; five judges contributed 25 of the correct judgments; nine judges, 27; and the remaining six judges, 6; and Rorschachs of mental defectives can be identified in 90% of the cases.
