grade men in typical groups. 



Nvunerous varieties of evidence indicate 

 the extreme military importance of the 

 prompt recognition of low grade men. 

 The percentages of men ranking below the 

 average in psychological examinatioas are 

 notably large for the disciplinary group, 

 men having difiSculties in drill, men re- 

 ported as "unteachable" and men des- 

 ignated by their officers as "poorest" from 

 the standpoint of military usefulness. 



The comparison of negro with white re- 

 cruits reveals markedly lower mental rat- 

 ings for the former. A further significant 

 difference based on geographic classifica- 

 tion has been noted in that the northern 

 negroes are mentally much superior to the 

 southern. 



The relation between officers' judgments 



of the value of their men and intelligence 

 ratings is exhibited in somewhat different 

 ways by Figs. 5 to 7. Thus the median 

 scores for five groups of privates arranged 

 in order of military value from "very 

 poor" to "best" are presented in Fig. 5.

group is 374. The men were selected from 

 twelve different companies, approximately 

 thirty men in each company being ranked 

 by an officer in serial order from "best" 

 to "poorest." The rank order for each 

 company was then correlated by the psy- 

 chological examiner mth the rank order 

 supplied by psychological examination. In 

 seven of the twelve companies the correla- 

 tions ranged from .64 to .75. The average 

 correlation was .536. These correlations are 

 high, considering the large number of fac- 

 tors which may influence a man's value to 

 the service.
