On Monday's Smart Talk explore the reasons Americans are so politically polarized. Author Jonathan Haidt argues that political affiliations stem from the elements people use to establish moral and ethical guidelines. The polarity of those ethical judgements force people to either the liberal or conservative side, that people are subject to their own psychological predispositions.

April Kelly-Woessner is Professor of Political Science and Chair of the Department of Politics, Philosophy and Legal Studies at Elizabethtown College where Haidt will speak this Thursday night. She has written extensively about political intolerance and the lack of viewpoint diversity in higher education. Dr. Kelly-Woessner appears on Monday's Smart Talk.

There have been a few examples within the past month. Author Charles Murray has been called a white nationalist and became best known after writing a book that claimed blacks weren't as intelligent as whites. Protestors became violent at Middlebury College in Vermont last month when Murray was scheduled to speak and shouted down Murray at Villanova University last week.
