I'm not a scientist, so it's harder to speak to that, but as an engineer, I can definitely say that engineers are in general more interested and more skilled at asking questions of "how" rather than questions of "why".
When I studied the humanities, I read Euclid, Galileo, Darwin, etc. The history of science is an essential part of the humanities. Unfortunately, it is not part of "STEM" in the sense that politicians use that term.
Scientific revolutions are definitely a case of "natural philosophy", but that differs dramatically from "normal science" as described, for example, in the Structure of Scientific Revolutions. I am likewise concerned that movement towards a jobs-oriented STEM curriculum will actually retard the progress of the sciences, by producing more functionaries and fewer deep-thinking scientists capable of innovation.
