I am not going to sink into a detailed methodological critique because 1) while I hate their antique methods this is unnecessary to make my point, and 2) I am writing for a general audience and want to demonstrate that any idiot can reject papers that uses such methods badly

suppose for a moment that this were actually true what do physical reality do you imagine might cause this outcome? what specific actions can you imagine all white doctors taking that no black doctors take that would *triple* infant mortality independent of everything else?

note that this is not actually what they found black infant mortality rate is triple the white rate, the effect they see drops that to (afaict) ~double the white rate

"Physician race is not coded by the data and is captured from publicly searchable pictures of the physician." non-white, non-black doctors were dropped from the analysis

lol if this is pure measurement error the "true" coefficients should be /greater/ ironically this possibility of measurement error decreases my confidence in the studys results

I get how measurement error would underestimate coefficients but why would it have different effect on white/black?

well I mean it would bias downward estimates of p(death | black, everything else) - p(death | everything else) and the other thing
