Others, like Mark Bauerlein, argue that professors in the humanities have increasingly abandoned proven methods of epistemology ("I care only about the quality of your arguments, not your conclusions.") in favor of indoctrination ("I care only about your conclusions, not the quality of your arguments."). The result is that professors and their students adhere rigidly to a limited set of viewpoints, and have little interest in, or understanding of, opposing viewpoints. Once they obtain this intellectual self-satisfaction, persistent lapses in learning, research, and evaluation are common.
