A study by Wendy M. Williams, professor of human development at Cornell University, and Stephen Ceci, the Helen L. Carr Professor of Developmental Psychology at Cornell, found that female applicants were strongly favored over men in an experiment designed to assess bias in hiring for professors in biology, engineering, economics and psychology. However, this studies results have been met with skepticism from other researchers, since it contradicts other studies on the issue. Joan C. Williams, a distinguished professor at the University of California's Hastings College of Law, raised issues with its methodology, pointing out that the fictional female candidates it used were unusually well-qualified. In contrast, Ernesto Reuben, an assistant professor of management at Columbia University said Williams' and Ceci's study is methodologically sound and Wendy Williams noted that faculty short lists are always made up of superb candidates. Studies using more moderately-qualified graduate students have found that male students are much more likely to be hired, offered better salaries, and offered mentorship.
