The Accuracy of Evaluations Made by Logical and Illogical Raters Using a Mixed Standard Scale Format

Abstract

The present study compared rating accuracy of logical and illogical raters on mixed standard scales. A laboratory methodology was used so that the true level of ratee performance would be available and Cronbach's (1955) accuracy components could serve as dependent measures. Analyses indicated that illogical raters were less accurate than were logical raters, but only on differential evaluation. Implications for personnel practice and future research are discussed.
