The Rorschach: not a "tell all" assessment

| No Comments

The Rorschach Ink Blot evaluation is one of the better known psychological evaluations out there. It has been shown in movies and other media, but is it really a "tell all" for whats going on inside? First, some history. The test originated in the early 1920s, developed by Hermann Rorschach for the same purpose it serves today, helping to diagnose psychological disorders. The test itself is fairly straight forward, a series of 10 blots are shown to the patient and the patient describes what they see. The test administrator evaluates the response based on characteristics of what the person describes, not the perceived image itself. The Rorschach is not a "tell all" evaluation though.


The Rorschach is often administered with the MMPI or other psychological tests. The purpose of using multiple evaluations serves to provide more consistent results. As we discussed earlier in the semester, if the results of a test aren't replicable, it's not reliable. The Rorschach has undergone a few changes since its creation. The test now uses Exner's scoring system, first developed in the 60's, but even with a fairly consistent scoring pattern, the validity of the test continues to be called into question. Illusory correlations may be responsible for some of this controversy, people may see things that don't relate to their personality at all. It is for this reason that the Rorschach isn't given by itself, for the sake of quality results.
