Comparison between two scales for the estimation of intelligence

Abstract

Compares Pearson's scale to a scale measuring ability of salesmen to estimate of intelligence. To standardize judgments on mental ability, intelligence was classified into nine categories, ranging from 'genius' to 'imbecile'. Both scales (1) were able to differentiate a university group from a non-selected group; a significant correlation was found between the two series of ratings (2) correlated by about the same amount with academic grades (3) correlated more closely with academic grades than with psychological test scores and (4) agreed with the available criteria of intelligence to about the same extent.
