I’m not appreciating the assumption that STEM majors have tougher curves and a heavier workload, either. I attended a LAC with engineering, and it was generally agreed that the non-STEM kids had more work to do but the STEM work was more difficult. Also, in terms of grades, it was next to impossible to earn above an A- there in the social sciences. After all, what research paper or essay is ever perfect? But if all the math problems are correctly solved, or if the best student solved 10/15 and everyone else only 5/15, he gets a solid A.
