> Most of us have an intuitive notion of NM already. I remember having the notion that if I threw a rock, it accelerated for a time after leaving my hand, before decelerating. I was disabused of that in physics class.

And it took a long time for people to figure that out (or how you see, or tons of other "intuitive" concepts). IMHO, if you had to chose only door one or door two, it would be better for students to leave school with an understanding of what the scientific process is (not even baconian scientific method) rather than the idea that science has some sort of weird epistemology of "facts" and "non-facts". The worst and loudest Gradgrinds of STEM education policy clearly have no idea of this.
