How powerful are rumors? Frequently, students ask friends and/or look at instructor evaluations to decide if a class is worth taking. Kelley (1950) found that instructor reputation has a profound impact on actual teaching ratings. Towler and Dipboye (1998) replicated and extended this study by asking (a) Does an instructor's prior reputation affect student ratings? and (b) Does the size of this effect depend on student characteristics. This case study presents only data relevant to the former question.
