Table 364. — Distribution of mental ages of 126 prostitutes on the Binet-Simon (Goddard revision) examination. (Port of 



Embarkation, Newport News, Va.) 



A group of 39 questionable women were examined at Ross County Infirmary, Ohio, by 

 the psychologists at Camp Sherman. This group was given examination alpha. No one 

 scored A; 5 per cent scored B; 8 per cent, C+ ; 28 per cent, C; 28 per cent, C- ; and 31 per 

 cent, D. By transmuting these scores into mental age (correlation with the Stanford-Binet 

 scale) we find that 31 per cent of this group had a mental age of 10 or under. A psychiatric 

 examination by an officer of the Medical Corps showed 15 per cent of this group also to be 

 abnormal in other ways. 



At Camp Greenleaf 71 prostitutes were examined in the Crittenton Home, Chattanooga, 

 Tenn., adjoining the camp. The psychological record cards of these women show the following 

 distributions : 



Stanford-Binet examination, 45 cases: 



Mental age 6 



Number of cases 1 



Alpha examination, 26 cases: 



Letter grade D 



Number of cases 1 



By transmuting the numerical score for the above alpha examinations into the correspond- 

 ing mental age we obtain the data presented in table 365. The combined result shows again 

 very clearly the low intelligence of prostitutes. There are 50.7 per cent with a mental age of 

 10 or under. This result agrees closely with the data from Newport News, which, although 

 quite differently derived geographically, showed 53.2 per cent with a mental age of 10 or less. 



Table 365. — Distribution of mental ages of 71 prostitutes on the Stanford-Binet examination ( Chattanooga, Tenn. — Camp 



Greenleaf examiners). 



In summary we may note that (1) the results of Army examining of prostitutes corroborate 

 we conclusion, attained by civilian examinations of prostitutes in various parts of the country, 

 that from 30 to 60 per cent of prostitutes are deficient and are for the most part high-grade 

 morons; and (2) that 15 to 25 per cent of all prostitutes are so low-grade mentally that it is 

 wise (as well as possible under the existing laws in most States) permanently to segregate them 

 in institutions for the feeble-minded.
