The entire population of the Illinois State Training School for Girls at Geneva was tested by Louise E. and George Ordahl.[18] The Kuhlmann revision of the Binet Scale, supplemented by the Stanford Scale, for the older ages, was used. Among the 432 tested 13 per cent. tested below our borderline for the presumably deficient and 22 per cent. more in the doubtful group. Dr. Otis, resident psychologist at the New Jersey State Home for Girls at Trenton, examined 172 girls between 10 and 20 years of age inclusive (_43_). Since she said it was “a preliminary testing” and “not many of the smaller girls were included,” we conclude that it was a somewhat selected group. She regarded those who stand between eleven and twelve as practically normal and those who stand below ten as without doubt defective. She then publishes three groups: “Defectives,” 45% (77 cases) high grade; “Morons,” 30% (52 cases); and “Presumably Normal,” 25% (43 cases). Since she does not give the distribution of the cases it is not possible to tell how many of her group were less than four years retarded. Her statement of the ages, however, shows that not more than 7 of the defectives could have been less than four years retarded and not more than 12 of the combined group of defectives and morons tested X or over. We may be sure, therefore, that at least 68% of these girls are of questionable intellectual ability according to the conservative standard adopted in this discussion. Dr. Bridgman has reported the examination of 118 girls, 10 to 21 years of age, successively admitted to the State Training School for Girls at Geneva, Ill. She states that 89% (105 cases) “showed a retardation of three years or more.” The distribution of cases is not given so that it is not possible to tell how many testing X, XI, and XII were classed as feeble-minded or how many tested only three years retarded. The published estimate is undoubtedly extreme, but I have no means of making a more conservative estimate on this group. It is interesting, however, to note that only 14 of the cases were not sexually immoral. These were all cases which were either dependent or sent because uncontrollable at home and all tested as passable intellectually. She states that “according to the Binet tests, 97% of the children (_5_) sent to this institution because of sexual immorality are feeble-minded as well.” This percentage also would be decidedly discounted on a conservative test standard. In another place Dr. Bridgman makes the important statement that of 400 girls admitted to Geneva 60% were suffering from venereal disease (_4_). Mr. Bluemel (_2_) found that 24 out of 50 girls sent from Judge Lindsay's Juvenile Court in Denver to the State Industrial School or the Florence Crittenden Home tested XI or under and four or more years retarded. This is less conservative than our standard, which would exclude those who tested XI as above even the uncertain group in intellect.
