It was found at Treasure Island that approximately 10% of the men passing through the Receiving Station could routinely be seen by the two psychiatrists present. A heavier load than this allowed the psychiatrists, who did a splendid job, to gain only a fleeting impression which was diagnostically unsatisfactory. When scores on the Experience Comparison Index became the basis for referral, a specific problem, which follows, obtruded itself. The partial distribution of scores made by the men diagnosed as maladjusted was, as desired, sharply negatively skewed. However, the tail of the distribution of scores obtained by the undiagnosed or "normal" men referred was not curtailed just above the cutting score as it had been hoped it would be. On the contrary, these "false positives" reached the ceiling on the questionnaire-30 symptomatic responses out of 30. The problem faced then seemed to be to force the aforementioned false positives down out of the upper ranges of the distribution.
