“…Attempts to validate the alleged relationship between Rorschach signs and such traits as constriction and impulsiveness have been no more successful (Carp, 1950;Holtzman, 1950). Very few such studies have been made.…”

Intra-individual consistency in response to tests of varying degrees of ambiguity.

“…Recent research, however, would seem to justify the caution of Bellak that "the projective hypothesis... has to be handled with considerable care" [1, p.5]. The literature is replete with findings which suggest that behavioral measures based on projective techniques may be inconsistent and unpredictable [3,5,7,11,16,22,25,26,27].…”

Development and Applications of Projective Tests of Personality

“…Hamlin, Albee, and Leland (41) found that only 6 of 26 signs distinguished between groups of 20 normal college students, maladjusted persons, and neuropsychiatric Veterans Administration patients. Carp (23) tested the entire third grade, 47 boys and 46 girls, in a public school with the Rorschach. She studied the relationship between scores on that test and performances on Draw-Your-Own Family, Draw-How-You-Feel tests, and scores on the McFarland Trait Rating Blank.…”
