BESIDES MEASURING THE SAMPLE GROUP, RESEARCHERS ALSO MEASURED THE HEIGHTS OF 100 OTHER BOYS ENTERING THE INSTITUTION. THE HEIGHTS OF THE 1,084 BOYS WERE STATISTICALLY DIFFERENT THAN EXPECTED; THERE WAS A HIGHER REPRESENTATION OF SHORTER BOYS (LESS THAN THE 3RD PERCENTILE) AND MEDIUM-HEIGHT BOYS (BETWEEN THE 3RD AND 10TH PERCENTILE). THE HEIGHT DISTRIBUTION OF THE 100 CONTROLS WAS SIMILAR TO THAT OF THE SAMPLE. THE CHROMOSOME ABNORMALITIES WERE ONE CASE EACH OF 47,XYY AND 47,XXY/46,XY MOSAIC. THE HEIGHT OF THE FORMER BOY WAS ABOVE THE 90TH PERCENTILE; THAT OF THE LATTER WAS BETWEEN THE 50TH AND 75TH PERCENTILE. THE STUDY DOES NOT SUPPORT THE SUGGESTION THAT TALLNESS INFLUENCES ADMISSION TO INSTITUTIONS FOR JUVENILE DELINQUENTS. (HUNTER, WRITING ON ADULT OFFENDERS, INDICATED THAT JUDGES WERE MORE LIKELY TO INSTITUTIONALIZE TALL OFFENDERS THAN SHORTER OFFENDERS BECAUSE OF THEIR THREATENING APPEARANCE.) IT IS CONCLUDED THAT THE NUMBER OF VARIABLES PRESENT IN SOCIETY REGARDING INVOLVEMENT IN ANTISOCIAL ACTS AND THE DETECTION, PROSECUTION, AND INSTITUTIONALIZATION OF OFFENDERS MAKES IT DIFFICULT TO COMMENT DIRECTLY ON THE RELATIONSHIP OF HEIGHT TO ANTISOCIAL ACTIVITIES. TABULAR DATA AND REFERENCES ARE PROVIDED. (DAG)
