Tracing the threads: How five moral concerns (especially Purity) help explain culture war attitudes

Commentators have noted that the issue stands taken by each side of the American ‘‘culture war’’ lack conceptual consistency and can even seem contradictory. We sought to understand the psychological underpinnings of culture war attitudes using Moral Foundations Theory. In two studies involving 24,739 participants and 20 such issues (e.g. abortion, immigration, same-sex marriage), we found that endorsement of five moral foundations predicted judgments about these issues over and above ideology, age, gender, religious attendance, and interest in politics. Our results suggest that dispositional tendencies, particularly a person’s moral intuitions, may underlie, motivate, and unite ideological positions across a variety of issues and offer new insights into the multiple ‘‘moral threads’’ connecting disparate political positions. 2012 Elsevier Inc.
