Using a group of 42 subjects who were members of a class in social psychology at Barnard College, a study was made to find the degree to which certain traits and abilities lend themselves to discriminative measurement within a relatively homogeneous group; to check the results on standard tests against results obtained from personal ratings; to find the correlation between certain personality traits. The correlations are, on the whole, of a positive order, and are in keeping with the general principle of the positive correlation of desirable traits, or, as otherwise stated, the principle that "correlation rather than compensation" is the rule in the development of human nature.
