A Projective test is a method of personality assessment in which an individual is presented with a standardized set of ambiguous, abstract stimuli and asked to interpret their meanings, wherein the individual's responses are assumed to reveal inner feelings, motives, and conflicts.
Although clinicians frequently use projectives, the subjective interpretation of responses to projective stimuli is problematic with regard to reliability and validity ( Beutler, 1995; Dawes, 1994). Recent refinements in scoring have focused on quantifying responses and comparing them to established norms ( Exner, 1993), with resulting improvement in reliability and validity.
It seems imperative that users score responses to projective tests objectively if adequate reliability and validity are to result. Without such objective scoring, the door is left open to biased interpretation. For example, if one believes the respondent is aggressive, one may tend to note responses that support such an impression and pay less attention to responses that do not fit as well.

History has shown that the scientific method is the most useful method for gaining reliable knowledge about the world. Will clinical practice improve with the adoption of empirically based rules?
Is there a place for subjective interpretation in psychological assessments and treatments or should clinical practice be guided by the scientific method?
