The present research examined whether students' likelihood to take a course with a male or female professor was affected by different expectations of professors based on gender stereotypes. In an experimental vignette study, 503 undergraduate students from a Canadian university were randomly assigned to read a fictitious online review, similar to those found on RateMyProfessors.com, that varied professor gender, overall quality score and level of caring for students. Students responded to items assessing their likelihood to take a course with the professor, perceived competence and warmth of the professor, and their own gender bias. An analysis of variance revealed an interaction between professor gender, student gender, quality score and caring. When quality score was low, male students indicated a lower likelihood of taking a course with female professors who were not described as caring. Regression analyses showed, however, that students' gender bias was negatively associated with likelihood to take a course with a female professor. These results imply that student gender plays a role in evaluations of female professors who do not display stereotypical warmth but that gender bias, which is typically higher for males at the group-level, may be an underlying factor.
