Ernest K. Coulter, as Clerk of the Children's Court of New York County, has raised his voice in protest against charging the Juvenile Courts with dealing mainly with feeble-minded children. He says: “The writer, who has seen at close range 80,000 children pass through the largest Children's Court in the world, has little patience with the sentimentalist who would pounce on every other juvenile delinquent as a mental defective” (_94_, p. 68). Unless we are to convert valuable propaganda for isolating the feeble-minded from good kindling wood into shavings, we must remove this cloud which has been cast upon the mentality of the ordinary children who are brought before juvenile courts of the country. Travis, (_202_) years ago, may have been nearer right when he said that 95% of the children who come before the Juvenile Court are normal. Surely this agrees better with the conditions found in Chicago, Denver, and Minneapolis. Possibly these western cities, however, show unusually good conditions. The evidence as to the peculiar local situations in Newark and Pittsburgh makes one confident that their detention home conditions do not at all represent the frequency of mental deficiency among ordinary juvenile offenders in these cities. I see nothing in the present evidence from mental tests to indicate that the frequency of mental deficients who might justly be sent to institutions from among the ordinary children who come before the juvenile courts of the country, would be over 10 per cent. 4. What shall we say as to the general frequency of deficiency among delinquents of all classes? How about the impression that a large proportion of them are not responsible because of their deficiency and that the condition is worse among juveniles? Note some of the published statements: “Probably 80% of the children in the Juvenile Courts in Manhattan and Bronx are feeble-minded.” “Preliminary surveys have shown that from 60% to 70% of these adolescents [sent to the industrial schools in one state] are retarded in their mental development and are to be classed as morons.” “Forty to 50% of our juvenile delinquents are without a doubt feeble-minded.” “The best estimate and the result of the most careful studies indicate that somewhere in the neighborhood of 50% of all criminals are feeble-minded.” “Nearly half of those punished for their wickedness are in reality paying the penalty for their stupidity.” “More than a quarter of the children in juvenile courts are defective.” “One-third of all delinquents are as they are because they are feeble-minded.” “It is extremely significant in the study of juvenile delinquency that practically one-third of our delinquent children are actually feeble-minded.”
