Abstract
This study investigates how counterstereotypical behavior affects the public beliefs about, first, career-related personality traits and, second, expertise in gender-stereotypical fields. The experiment elicits stereotypes of an individuals' personality and expertise: Subjects are presented a description about a (theoretical) person who is featured as either exhibiting stereotypical (assertive man or unassertive woman) or counterstereotypical (unassertive man or assertive woman) behavior. Then, they are asked to rate this person’s personality traits and expertise in various gender-specific categories on a seven-point scale. Subjects are thereby incentivized to not reveal their own belief but to correctly anticipate the modal response of beliefs reported by others.

The effect of the treatments on several outcomes will be measured. Those outcome measures can be categorized into two different groups: (1) personality traits and (2) expertise.

Personality traits: Honesty, Emotionality, Extraversion, Agreeableness, Conscientiousness, Openness to Experience, Likeability, Trustworthiness

Expertise: Sports, History, Mathematics, Pop Culture, Arts & Literature, Cooking

Experimental Design
Experimental Design
In this experiment, participants will be randomized into one of four groups such that each participant will have a 25% chance of being randomized into any given group. Subjects are presented a description about a (theoretical) person who is featured as either exhibiting stereotypical (Treatment 1: assertive man, Treatment 2: unassertive woman) or counterstereotypical (Treatment 3: unassertive man, Treatment 4: assertive woman) behavior. Then, they are asked to rate this person’s personality traits and expertise in various gender-specific categories on a seven-point scale. Subjects are thereby incentivized to not reveal their own belief but to correctly anticipate the modal response of beliefs reported by others.
