“…While some individual studies have reported positive correlations between self-assessments and objective ability measures (e.g. Bailey & Lazar, 1976;Karnes & D'Ilio, 1988; Levine, Flory, & Ash, 1977; Lowman & Williams, 1987), others strongly challenged the validity of the method, finding it to be more lenient than peer or supervisor ratings, while showing more bias and less discriminant validity (Harris & Schaubroeck, 1988;Mabe & West, 1982;Powel, 1948;Smith & Strein, 1987;Stutzman & Jawetz, 1982;Thornton, 1978). In a meta-analysis of 55 studies in which self-evaluations of abilities were compared with measures of performance, Mabe and West (1982) found a low mean validity coefficient (.29), with high variability (SD = .25); they noted that some personal characteristics, namely high intelligence, high achievement, and internal locus of control, were associated with more accurate evaluations.…”
