This study investigated whether the gender of manuscript authors affected reviewers' editorial decisions. Female and male reviewers for five behavioral journals were asked to evaluate identical manuscripts according to their usual criteria. Half the manuscripts were supposedly written by men and half by women. Male reviewers did not evaluate male- and female-authored manuscripts differently. Female reviewers accepted significantly more female-authored (62%) than male-authored (10%) manuscripts. Female-authored manuscripts were accepted significantly more often by female (62%) than by male (21%) reviewers. Information unrelated to the quality of the manuscript appears to have influenced reviewers' decisions. Implications for the journal review process are discussed.
