My experience as a White patient (and this is just anecdotal of course) is that the two Black doctors who were my primary care physicians (both osteopaths, if that matters, one man and one woman) were much more likely to spend time listening to and talking with me and looking beyond standard treatments than were the White primary care--"zip in, zip out"--physicians I had.

And then there's this recent study: "The findings suggest that Black physicians outperform their White colleagues when caring for Black newborns." ( https://www.cnn.com/2020/08/18/health/black-babies-mortality-rate-doctors-study-wellness-scli-intl/index.html )

Perhaps Black doctors are in general more attentive to ALL patients. The stereotypes behind the microaggressions described here seem to be not just a RESULT of lack of diversity but a CAUSE of the lack of diversity, and these stereotypes may not be limited solely to patients but to administrators and teachers.
