This study examined gender bias on job performance in work settings where c
onfounding variables (e.g., organizational level, experience, education) we
re cautiously taken into consideration to ensure fair comparisons. Although
previous meta-analyses examined gender biases on evaluations, findings in
tightly controlled laboratory environments may differ from those in highly
complicated field studies. We found little evidence of overall gender bias
in performance appraisals in nonconfounded field studies. However, there we
re significant pro-male biases when only men served as raters. Measure-spec
ific gender stereotypicality, instead of general stereotypicality about the
job, produced gender bias in performance appraisal. Masculine measures pro
duced pro-male bias, and feminine measures produced pro-female bias.
