Aún los detractores del Rorschach coinciden en las bondades del Sistema Comprehensivo de Exner

Few evaluators using the Rorschach acknowledge its limitations.  If the Rorschach is used, its limitations should be clearly noted unless the Exner system is used.  And then, it is necessary to say what is being scored by the Exner system.  But often, idiosyncratic interpretation techniques are used to form conclusions and make recommendations which affect the lives of people.

There is no empirical support for the validity of the Rorschach, except when the Exner system is used.  Reviews in the Buros Mental Measurement Yearbook for every year in which this test has been reviewed state that there is no research demonstrating its validity. For example, in the Eighth Mental Measurements Yearbook Peterson concluded: "The general lack of predicted validity for the Rorschach raises serious questions about its continued use in clinical practice."
