Effects of Age on Ranking for Reduction in Work Force

Abstract

A laboratory experiment tested the hypothesis that age and written descriptions of performance affected simulated evaluations for reduction in work force. 56 supervisors and managers attending night school reviewed written descriptions of seven individuals' performance. Seven different ages ranging from 25 to 63 years were paired with each individual's performance in a within-subject Latin square design. Each subject rated seven simulated individuals on 10 attributes and made recommendations in the form of comparative rankings for a simulated reduction in force. Chronological age effects on performance rankings were not found. Statistically removing rating components (work performance and sociability) from rankings using an analysis of covariance also yielded no age-related bias but did indicate that the subjects were able to distinguish among performance descriptions. These findings are discussed in relation to the Age Discrimination in Employment Act.
