> so probably some form of home economics, sales & negotiating, psychology, and such

So, I actually took home ec because I had an otherwise dead period in the middle of the day that had to be filled, and, aside from mechanics of cooking, it was largely hyperspecific applications of math proficiency. Psychology is a science. So, I mean, the specifics on your list aren't really holding up the anti-STEM thesis. Anti-TE maybe, though maybe if you added the next three important items, two of them would cover those areas as well.
