I've noticed in interdisciplinary work with specialists in technical fields that they always expect terms from other disciplines (like philosophy) that they don't recognize to be clearly defined the moment they are used, but don't feel the need to define their terms. This is particularly bedeviling when the intended audience themselves are non-technical.

Maybe this tendency arises from them coming from a discipline with such sharply defined concepts that it never even occurs to them that other people won't understand (although I've learned firsthand that these concepts are actually often very fuzzy in their own right). Maybe it's also an unconscious expression of a sort of privilege, insofar that society prioritizes technical disciplines over all others.

Whatever its cause, I've encountered the phenomenon from very well-meaning technical specialists, even those who are actively interested in overcoming the divides between disciplines and between audiences.
