Three hundred sixteen undergraduate students from two liberal arts colleges rated the ethical nature of six different fictional scenarios. Each scenario described interactions between a professor and student. The gender of the fictional professor was varied randomly. Thus, for any particular scenario, a participant may be rating the behavior of a male professor or a female professor. The gender of the fictional student was also varied randomly in some scenarios. Results indicated that the gender of the professor does appear to affect students' ethical ratings of some scenarios. The gender of the professor also appears to interact with the gender of the rater in some cases, with women tending to rate a male professor's behavior as more unethical than a female professor's behavior. In general, women tended to rate the behavior of the professor as more unethical than did men, regardless of the professor's gender.
