This is the "default white" background framing in which people try (unsuccessfully) to share Black accomplishments in science, technology, and society.
For me to say that my dad is a heart transplant surgeon, feels like a magical Black accomplishment. But the first successful open heart surgery was done by a Black doctor. And the first c-sections where mothers consistently survived were done by Black doctors.
I reject the entire premise of some Black folk being medical geniuses, as surprising.
