An Empirical Exploration of Moral Foundations Theory in Partisan News Sources

Dean Fulgoni, Jordan Carpenter, Lyle Ungar, Daniel Preoţiuc-Pietro


Abstract
News sources frame issues in different ways in order to appeal or control the perception of their readers. We present a large scale study of news articles from partisan sources in the US across a variety of different issues. We first highlight that differences between sides exist by predicting the political leaning of articles of unseen political bias. Framing can be driven by different types of morality that each group values. We emphasize differences in framing of different news building on the moral foundations theory quantified using hand crafted lexicons. Our results show that partisan sources frame political issues differently both in terms of words usage and through the moral foundations they relate to.
