For example there’s recently been a controversy adjacent to this topic on Twitter involving one Philip Goff (philosopher) who started feuding over it with Sabine Hossenfelder (physicist, albeit with some controversial opinions). Basically Hossenfelder took up an instrumentalist position of “I don’t need to assume that things described in the models we use are real in whatever sense you care to give to the word, I only need to know that those models’ predictions fit reality” and Goff took issue with how she was brushing away the ontological aspects. Several days of extremely silly arguments about whether electrons exist followed. To me Hossenfelder’s position seemed entirely reasonable, and yes, a philosophical one, but she never claimed otherwise. But Goff and other philosophers’ position seemed to be “the scientists are ignorant of philosophy of science, if only they knew more about it, they would be far less certain about their intuitions on this stuff!” and I can’t understand how they can be so confident about that or in what way would that precisely impact the scientists’ actual work. Whether electrons “exist” in some sense or they are just a convenient mathematical fiction doesn’t really matter a lot to a physicist’s work (after all, electrons are nothing but quantized fluctuations of a quantum field, just like phonons are quantized fluctuations of an elastic deformation field; yet people probably feel intuitively that electrons “exist” a lot more than phonons, despite them being essentially the same sort of mathematical object. So maybe our intuitions about existence are just crude and don’t well describe the stuff that goes on at the very edge of matter).
I see. Yes, “philosophy” often refers to particular academic subcultures, with people who do their philosophy for a living as “philosophers” (Plato had a better name for these people). I misread your comment at first and thought it was the “philosopher” who was arguing for the instrumentalist view, since that seems like their more stereotypical way of thinking and deconstructing things (whereas the more grounded physicist would just say “yes, you moron, electrons exist. next question.”).
From the discussion it seemed that most physicists do take the realist view on electrons, but in general the agreement was that either view works and there’s not a lot to say about it past acknowledging what everyone’s favorite interpretation is. A question that can have no definite answer isn’t terribly interesting.
