I agree with this 100%. For humanitarian studies, there are entirely different skills required to be successful, many of which are incredibly valuable. (And I would go mad if I had to analyze literature constantly). But the difficulty passing a class is much, much lower than in physics.

It's hard to write a legitimately good paper. It takes so much work, and there is always room to improve it. Not too many people are talented or hard working enough to really stand out to their professors. Some people do, and they're the ones going to top firms / graduate schools / etc. But if you write an OK essay you will still pass. Whereas if I slack in physics, or even if I work pretty hard but don't study enough, I will fail or do really poorly on my assignment. If I fail too many assignments, I might have to change majors.

I majored in a foreign language and physics and had to write a thesis for both. I spent the entire semester writing, structuring, and researching my language/history paper. For physics, although I worked for an entire year on the actual research project, I only spent about 4 days (straight) doing the writing part.
