When I was an undergrad in college, I helped design a study on the role of gender perception in expertise. We had a piece of text that the subjects (undergrads) would read and rate the expertise of. We had the same text but we randomized whether the name would be a commonly male name, a commonly female name, or initials. We also randomized if they'd watch a clip of men's sports beforehand (men's basketball), women's…
