Very open to it being BS, but if so I'd really like to know what problem causes the result! I imagine it's a useful story with lessons for other studies, whatever it is.

I think its failure is massively overdetermined unfortunately

if black patients have higher underlying/latent risk and white docs are assigned to higher risk patients , unless you measure that risk very accurately, white doctor/black patient outcomes will be worse, even "controlling" for risk, bc drawing from a higher risk distribution

The physician FEs should cover it if it's just white docs getting higher-risk patients in general, but if some docs see white lower-risk parents while also getting a more diverse set of higher-risk ones, that could create the interaction they found.

To me the biggest hurdles for any theory are the physician FEs, the fact the effect is specifically on the interaction, and the fact you need a theory where healthier blacks are more likely to have black docs, which is somewhat counterintuitive.

Is that counterintuitive? Wealthier people are more involved in physician selection, and it seems realistic for them to select doctors like themselves. Poorer people get whoever's around when they show up. (Whether this is empirically true is another matter).

Yeah, that's one of the most plausible explanations this endless branching thread has produced!

so at this point you've identified one reason the results are potentially borked and you havent even touched on model selection and specification, error estimation, or overfitting this is why I just dismiss this sort of thing out of hand

"Researcher degrees of freedom" is a general problem, and here it's turned up to eleven. They make tons of non-standard design choices and either justify them poorly or not at all. Default position should definitely be that the study is nonsense.

friendly disagreement with the point that it's nonstandard in this case--reads to me as very standard (and that standard is, Bad)

Hard for me to disagree with that because I get asked to review 3-4 papers like this a month. Very common and for that reason all the more frustrating.
