From the New York reformatory for women at Bedford Hills we have the following: “Realizing that a large percentage are subnormal, July 1, 1911, we employed a trained psychologist who will make it a year’s study.” From juvenile institutions the returns are neither more hopeful, nor more satisfying, and many institutions of that class seem to have no special facilities for caring for weaklings, and depend upon a relaxation of the discipline in their behalf. A study of 200 in the boys industrial school in Kansas disclosed that 174 were mentally dull, markedly defective, or two or more years behind their proper place in school. In the industrial school of New Hampshire about 75 per cent. are reported to be four to five years below their normal grade in school. Other letters say “probably 25 per cent., at least;” “one-third;” “50 per cent.;” “to a very large extent;” and so forth. The Idaho industrial training school reports: “A very small per cent.; I think not above five per cent.;” and the Georgia state reformatory reports that “the discipline has to be based on the fact that 75 per cent. of inmates are mental defectives and 99 per cent. are moral defectives.” The girls industrial home of Ohio says: “Fully nine-tenths are subnormal mentally, and a large per cent. physically weak or crippled.” From the Iowa industrial school for girls comes the following: “There is a certain inferiority, either mental or constitutional inadequacy, in each and every one. In the majority of cases it is a weakness; that is, they are easily influenced, therefore easily led astray.” It seems fair and right to allow for a difference among the writers as to the full import of the question to which they have responded, but that may not entirely account for the considerable differences in estimates. Possibly varying court proceedings, and the use of the power of probation by some of the courts or other exemptions from detention, may, in some places, have culled out most of the normal children. Your committee rather inclines to think however that longer and more extensive experience, in many cases, tends to fix in the mind the necessary recognition of a grave amount of mental inadequacy and constitutional inferiority, calling for custodial care, among all classes of delinquents, including juveniles, no less than adults. While the incompetents remain with the normal persons in labor, in school, and in recreation, the progress of the bright is certain to be retarded by the association, while the outlook for the dull is not improved. This mingling and attempted classification of unequal units seems to be the rule almost everywhere, with consequent lowering of efficiency and tone, to the basis of the inferior.
