[Vol. XV, 



Independent ratings of the same men by two or more officers were not requested. It is not 

 possible to state whether the rating of one man originated with one officer only, or as the com- 

 bined judgment of two or three in conference, nor can it be said whether all the men in a 

 given company were rated by the same officer. There is good reason to believe that all the 

 ratings were painstakingly made, and are thus of considerable value, for the rating officers had 

 had four months of acquaintance with their men, and the regimental adjutant urged upon the 

 officers the desirability of careful judgments in the interests of scientific investigation. 



Examinations alpha, beta, and a were used and the distribution of men by companies, 

 groups, and procedures is given in Table 80. No segregation was made. Every man, illiterate 

 or otherwise, took both examinations of the pair given his group. 



Table 80. — Distribution of men by companies, groups, and examinations — Camp Meade. 



In Camps Beauregard and MacArthur the cooperation of several organizations was ob- 

 tained. Three independent ratings of each man were requested according to the following scale: 



INSTRUCTIONS FOR RATING MEN ON GENERAL INTELLIGENCE. 



1. An estimate of the general intelligence of each man in your company, of whose mental capacity you have been 

 able to form even a rough notion, is desired from you. 



2. Beside each man's name enter the number representing the class of intellectual ability in which you think 

 he belongs. 



3. The classes of intelligence to be used are as follows: Class 7, very superior; class 6, superior; class 5, high aver- 

 age; class 4, average; class 3, low average; class 2, inferior; class 1, very inferior. 



4. The following points should be noted carefully: 



(a) The above scale refers only to intelligence, not to personality in general, total military value, etc. 



(6) It is meant to cover all ranges of intelligence which you have observed among enlisted men, not merely the 

 range from the brightest to the dullest of your own particular group. 



(c) It follows that 1 and 7 represent fairly extreme cases, one or the other of which may not have many repre- 

 sentatives in the group under consideration. 



This scale is much less specific in its definition of the various grades of intelligence than is 

 the scale used in Camp Meade, but, on the other hand, is probably less completely restricted 

 to the military point of view. The Camp Meade scale is obviously pretty exactly defined by the 

 normal selective agencies of the Army. To use the scale one has only to know enough cor- 

 porals, sergeants, etc., in order to estimate the averages required and then compare this result 

 with the mentality of the individuals to be rated. 



The various grades of the scale are thus fixed absolutely as well as relatively. The scale 

 used in camps Beauregard and MacArthur, in so far as it is defined in general terms, having no 

 absolute meaning, suffers in comparison with the Meade scale. 



The cases selected for study are as follows: 



Camp Beauregard, Twenty-ninth Infantry: Company A, 32 cases; Company B, 36 cases; Company C, 40 cases; 

 Company D, 46 cases; Company E, 61 cases; Company F, 56 cases; Company G, 62 cases; Company H, 44 cases; 

 total, 377 cases. 



Camp MacArthur, Fifth Battalion, Infantry Replacement Camp: Company G, 144 cases; Company H, 154 cases; 

 total, 298 cases.
