a larger number of correct predictions than could be made on the basis of a simplified approach to the problem? And further, do inexperienced judges show greater variability and more disagreement in their predictions than a group of more experienced judges? Within the limits of the study it was found that all 9 of the experienced judges and 4 of the 6 inexperienced judges were able to predict psychiatric diagnosis at the .01 level of confidence or better. Nevertheless, when comparing the performances of both groups as a whole, it was found there was a significant difference in favor of the experienced group in its ability to predict more accurately and also to make significantly fewer idiosyncratic selections. These results notwithstanding, it was also det.ermined that none of the judges succeeded in predicting more accurately than could be done simply by sorting the profiles according to the highest abnormal T scale score. The results also raise the question as to the legitimacy of using the MMPI for accurate individual diagnostic prediction in clinical consultations. This study serves to emphasize the pressing need for obtaining validity estimates for all of the clinical psychological tests included in the clinician's tool kit. BIBLIOGRAPHY 1. BORKO, H.
