Sorry to keep adding thoughts, but this is an elaboration on a prior thought. My S24’s STEM interest is Bio, but he is also interested in non-STEM things.
MIT at least has Bio, and I included it in this comparison, but even then it is not necessarily a core strength of MIT. Like, Yale had 176 Bio primary major undergrad dgrees, plus another 39 Cognitive Science. MIT had only 42 Bio, although 40 Cognitive Science.
Contrast that with Physics. 50 at MIT, 36 at Yale.
So I think that is sort of supporting my thesis too, in that the “line” in terms of relative weight is basically being drawn between Physics and Bio, which is a pretty math-related line in my view.
