In 2016, researchers at the University of Virginia published a study that should have ended a myth and instead just documented how deep it runs. They surveyed medical students and residents and found that a startling share believed things like: Black people’s skin is thicker than white people’s. Black people’s nerve endings are less sensitive. Black people’s blood coagulates faster. None of it is true. All of it traces back to justifications slaveholders used to defend forced labor and brutal treatment. And the students and residents who held those false beliefs rated Black patients’ pain as lower and recommended less accurate pain treatment for them than their peers who didn’t.

That study explains a pattern that shows up everywhere researchers look for it. Black patients are less likely to receive pain medication in emergency rooms for the same injuries as white patients including for something as unambiguous as a broken bone. Black women in particular carry a second layer on top of that: the well-documented “angry Black woman” stereotype, which research shows shapes how clinicians interpret assertiveness about pain read not as advocacy, but as aggression, and responded to accordingly.

The clinical consequences are not abstract. Black women wait years longer, on average, for an endometriosis diagnosis than white women, in part because their reports of severe pain are more likely to be minimized or attributed to psychological causes before a physical cause is investigated. Uterine fibroids which disproportionately affect Black women, often more severely carry a similar pattern of delayed diagnosis and delayed pain management.

This is not a story about individual bad doctors. It’s a story about a false belief that got embedded in medical training decades ago and never fully got removed — the same shape as the eGFR formula, the same shape as the 988 map. The belief doesn’t have to be conscious to change the treatment. It just has to still be there.
