Researcher-Subject Relations | Behavioral: Black Respondents Exposure to a Photo | Not Applicable |
We plan to recruit subjects and randomly assign them to one of four treatments. In each treatment arm, the subject will view a photograph of a real NIH investigator. We experimentally vary treatment along two dimensions: whether the sender is Black or white and whether the sender is male or female.
Our primary aim is to assess whether the subject's stated willingness to participate in a clinical trial led by the investigator. Our secondary aim is to assess whether the subject is a more objective measure of interest in signing up for information on other clinical trials. To assess mechanisms, we will ask the respondent to rate the subject's perceived trustworthiness and quality of the investigator. In addition, we will also assess the subject's perceived attractiveness and age of the investigator as well as the subject's risk aversion, altruism, time preference, and general trust.

Behavioral: Black Respondents Exposure to a Photo
Black survey respondents will be randomly assigned to one of four treatments. In each treatment arm, the subject will view a photo of an NIH investigator. We experimentally vary treatment along two dimensions: whether the investigator is a man v. woman and whether the man is white vs. black. We will survey participants' willingness to participate in a clinical trial and how their initial response is impacted by other characteristics such as perceived trustworthiness and quality. |
