@LHS2017 Always consider the scene in those depts and how they deeply engage their students. Also, if not many people were doing them or interested, there is no reason that they would offer so many joint-majors or have joined say a QTM substantive area. Go back on the websites for each and look at the course offerings, special programs, and happenings in the dept and see if you still have the same concern afterwards. At most R1 and elites, often the STEM scene is more visible any given day but that is often because engagement in other areas looks dramatically different. As for disadvantage 1/2 of the Two Marshall Scholars was a humanities major, most of the recent cycle of Fulbrights were, and the most recent Rhodes Scholar was. They also tend to win top graduation awards (such as Emory’s Britain Award, or the Bobby Jones Scholarship). They clearly have tons of access to opps and are well respected on campus.
In addition, there is the ILA, which is well known in academia because of how long the IDS program has been running. You don’t get depts like the ILA, a Voluntary Core, or the IDEAS Fellowship at places where non-STEM folks are put on the back burner.
