Googling around seems that it's contentious, and that a lot of people consider nurses, physicians etc to be STEM careers under the 'science' heading. But this doesn't seem all that core to me. (And you have to draw the line somewhere - are psychiatrists STEM? How about psychologists?)
Many people who go on to go to medical school will major in a STEM subject in undergrad (like biology or something)
This is a US-centric view - most people do in fact study medicine right out of school. It is interesting though that the definition of what constitutes a field vary quite greaty around the globe.
The M is not for Medicine
Actually, I am unsure how country specific this is and where to put medicine with respect to hard sciences, soft sciences, social sciences etc.
It is kind of hilarious how different this works in a lot of countries. For example in German, the translation of science is 'Wissenschaft'. It would literally translate to "the thing you do to make knowledge". Humanities are called 'Geistes'wissenschaft and Law is called 'Rechts'wissenschaft'. Math is generally considered to be part of the humanities, and CS is usually either part of the math-department or very closely settled to the engineering department.
There's many more differences between the german and anglo academic culture, let alone all the other ones out there.
Hm, not always. In my experience it was a B.Sc., M. Sc. and Dr. rer. nat. and in the math-nat department, but it can also be associated with philosophy and of course there is no scientific method in math.
For medicine you also have the (again country specific?) question whether a medical doctorate is comparable to a hard science one, e.g. for the purpose of grants in medical research.
How can anyone get a qualifying score on the MCAT without significant exposure to science?
Disclaimer: I'm definitely coming at this from a U.S. point of view which someone mentioned in another comment effectively (not always but definitely in the overwhelming majority of cases) requires STEM undergrad degrees to get into medicine.
So people tend to disagree about where to put medicine. But overall, most major public institutions in the US don't include medicine in STEM:
* US Department of Labor (Bureau of Labor Statistics) -- No. (https://www.bls.gov/careeroutlook/2007/spring/art04.pdf)
* US Department of Commerce (Economics and Statistics Administration) -- No. (https://files.eric.ed.gov/fulltext/ED522129.pdf)
* NSF -- No. "The National Science Foundation is a United States government agency that supports fundamental research and education in all the non-medical fields of science and engineering."
Just because there are other skills needed besides science based ones doesn't mean it isn't a science field.
People differ in whether they think medicine and the other applied sciences fall under the 'science' umbrella or not. Try searching around and you'll see a lot of mixed opinions on the subject.
Medicine-aligned subjects do a lot to improve the gender ratio, if one wants to improve the gender equality figures...
