Learning Objective
Identify and describe the critiques associated with the Rorschach Inkblot test.
Abstract
I begin by recalling Scott Lilienfeld as a valued collaborator who joined Howard Garb, Teresa Nezworski and me in our critiques of the Rorschach Inkblot Test. I then discuss an insight that gradually emerged from our years of work together: A test with inaccurate norms, such as the Rorschach, can be worse than useless because it misidentifies a high proportion of normal individuals as disordered. The validity of test interpretations depends on accurate norms at least as much as it does on the size of validity coefficients.
