CHAPTER 12. 



DISCIPLINAKY CASES. 



Tho data for the study of disciplinary cases came from two sources. At Camp Dix an 

 extensive examination was made, of 939 whites and 484 negroes convicted by summary and 

 special courts-martial from July to November, 1918. Like data were secured for 597 men 

 convicted at Camp Cody and 65 men in the depot brigade stockade at Camp McClellan. 

 Further data were obtained through the study at the United States Disciplinary Barracks 

 at Fort Leavenworth, Kans., of some 3,300 records made by the men confined there. 



Section 1 . — Level of intelligence of disciplinary cases. 



In the depot brigade at Camp Dix, during the months June and July, 1918, there were 

 479 white offenders. The figures in tables 345, 346, and 347, which show the distributions 

 of the psychological ratings of these men, indicate that 21 per cent of these offenders had an 

 intelligence rating of E. This means that these men were in the lowest decile of the Army 

 so far as intelligence is concerned. Such a rating means that the psychologist recommends 

 discharge for mental deficiency, assignment to labor or development battalion, or to some 

 duty requiring less than average mentality. Considering the group in relation to what is 

 approximately average intelligence, the C rating, we find that 66.4 per cent of the men are below 

 the average and only 10.4 per cent above it. Comparison with the white draft is significant, 

 for only 7 per cent of the white draft, as shown by the principal sampling for Hollerith analysis, 

 were rated E, and only 47.7 per cent were rated below the average. The percentages show 

 that these low-grade men are two or three times as likely to commit offenses as men of average 

 intelligence, and from four to six times as likely to get into trouble as are men of markedly 

 superior ability.
