Abstract
Both sociometric scores and scores on the Lorge-Thorndike Intelligence Test were available for all fourth grade classes, containing a total of 2,800 children, in one city. The schools were classified into quartiles on SES, making use of a combination of adult income and education from the 1960 census values. At each of these four SES levels, the group of high boys and high girls defined as those with sociometric scores one SD or more above the mean, were compared in IQ with the low boys and low girls, defined as those with sociometric scores one SD or more below the mean. The difference between the high and low groups at different SES levels ranged from 11.5 to 22.1 IQ points with all but three values falling between 15 and 20 points. There was no consistent trend for the difference in IQ between high and low girls or boys to be greater at one level than another.
