> Would you say I'm being a "STEMlord" if I said Caltech students were more likely than, say, students in Julliard's piano bachelor's degree program to be able to evaluate evaluate whether someone making a claim about the theoretical upper limit on the efficiency of a classical thermodynamic engine is correct?

If I personally knew a bunch of Julliard students who did a better job at this than Caltech students, then I'd certainly ask for some actual data backing up your claim. I see no reason why a freshmen majoring in CS is more likely to make healthy pandemic choices than a freshmen majoring in history.
