Science classes require more work because the average GPA is lower. To get the same GPA in a science class as a humanities class, you have to do better than more people than you would otherwise, which means more work. And yes, I agree that decreasing the average GPA in humanities classes is better, but you're ignoring one thing; students are horrible complainers. If you give them a poor grade, they will whine and wheedle. If it's on a test, and their answers are demonstratively false, they have no room to argue. If it's a paper, they will plead and annoy you until the cows come home. Simply put, poor grades in a science class are much more defensible because science isn't as subjective. It's hard to grade hard in a humanities course.
