> Importantly, if used, such models would lead to more patients who are Black and female being *incorrectly* identified as healthy

I think this is the point a lot of people are missing; they think, "So what if 'black' correlates to unhealthy and the model notices? It's just seeing the truth!"

However, I'm still wondering how this incorrectness works; can anyone explain?

Edit: Clue: The AI is predicting self-reported race, and the authors indicated that self-reported race correlates poorly to actual genetic differences.

My guess is that they are using an american dataset. This I would suspect encodes socioeconomic data into the samples. ie rich people, have access to better diagnostics, get seen earlier and are treated sooner. Conversely poorer present later and with more obvious symptoms. also the type of system used to take the images would also be strongly correlated.
