On the prediction of aggressive behavior from the Rorschach.

Research on predicting aggressive or hostile behavior from the Rorschach was reviewed. This overview suggested that the propensity for acting aggressively or in a hostile manner seemed less related to the quantity or quality of aggressive content than to indicators of impoverished control, e.g., CF+C > FC, F + % < 70, what some Rorschachers refer to as 'ego control.' However, methodological issues in the research on content which could have compromised these results were also discussed as was the kind of research still needed.
