ABSTRACT
Charles Spearman is perhaps best remembered for his contribution to our understanding of intelligence by advancing the concept of general cognitive ability, g. He noted that this was the general or common portion of all cognitive ability tests. Although Spearman first derived g in the educational setting, the importance of g in the prediction of occupation criteria has been and continues to be the center of a controversy (Calfee, 1993; Green, 1994; Jensen, 1993; McClelland, 1993; Ree & Earles, 1992; Ree, Earles, & Teachout, 1994; Schmidt & Hunter, 1993; Sternberg & Wagner, 1993).
