Social scientists from University of Southern California, the University of Virginia and New York University investigated the moral stereotypes that political liberals and conservatives have of each other. Not surprisingly, they discovered that liberals and conservatives tend to exaggerate the tendencies of their polar opposites. Each extreme tends to exaggerate their own moral commitments. Surprisingly, their study showed that liberals are less accurate in describing both themselves and their conservative opposites than conservatives are. Liberals, for example, tended to underemphasize conservatives’ commitment to the protection and fair treatment of individuals (PLOS One, December).
