Why send your child to one of the "most rigorous colleges" in the US but not highly ranked?

I don’t know, but many students do have certain perceptions. Could be the result of a “competitive” environment. There are also things like STEM folks putting down humanities and social science majors even though many (if not most) wouldn’t dare taking some of the more intensive social science or humanities courses for their gen. ed requirements. Again, such folks pretty much just go to RMP to ensure they picked easy gen. ed instructors.
