Effects of company rank on LGD performance of oil refinery supervisors

Abstract

LGD scores of 131 supervisors at a large oil refinery were correlated with company rank, education, intelligence, supervisory aptitude, youth, forced-choice evaluations, and graphic ratings by superiors. When rank was partialed out, LGD scores showed a high positive relationship with superior's appraisals. "It was concluded that the LGD is not valid where participants are of known different rank." The authors raise questions about the validity of superior's appraisals as criteria of supervisory performance, and about the influence of rank on LGD participants.
