I remember that my statistics professor was so smug about grading on a curve because it was using statistics. It was also a class that he gloated about as a class where you “needed an a” if you wanted to get into grad school. In other words, the asshole was making sure only a certain number of people even had a chance to get into the graduate programs. It was rumored that he even ran tests on students in the different labs, telling the grad students teaching the labs to teach in certain ways and seeing if there were any differences. Wouldn’t put it past him.
