Abstract: We investigate whether increased racial diversity of clinical trial principal investigators could increase the enrollment of Black patients, which currently lags population and disease-burden shares. We conducted a survey experiment in which respondents were shown a photo of a current NIH investigator in which race (Black/White) was randomized. Sex was also randomized as a relevant benchmark. Black respondents reported 0.35 standard deviation units higher interest in participating in a clinical study led by a race concordant investigator (a 12.6% increase). Sex concordance had no effect. Further analyses indicate that perceived trustworthiness and attractiveness are the most important factors explaining these results.
