They can go through their entire education without coming across a principled, non-left viewpoint.
In late January 2019, Kenneth Mayer, a political-science professor at the University of Wisconsin, drew the attention of a Republican state legislator for language in his syllabus that described Trump as “a president who gleefully flouts the norms of governing and presidential behavior.” His supporters see this as “not a bug, but a feature,” the professor wrote in his syllabus, adding, “To others, he is a spectacularly unqualified and catastrophically unfit egomaniac.” In response, the campus issued a statement supporting Mayer, stating that he “leaves his political opinions at the classroom door and asks his students to do the same.” Regardless of one’s views of the current administration, it is difficult to support the claim that Mayer’s opinions stayed at the door, given that they’re embedded in the course syllabus. Professor Mayer’s endorsement of a singular political perspective in the classroom points to a larger problem that plays out more broadly and has serious implications.
We can trace the current level of political polarization to multiple sources, but, whatever the causes, we could arguably reduce polarization by increasing our ability to see issues from perspectives other than our own. Given its potential to bridge divides, nurturing this ability should be a high priority. And yet, this is neglected in one of the places where it could do the most good: the college classroom.
