Abstract

Healthy democratic polities feature competing visions of a good society. They also require tolerance, trust, and cooperation to avoid toxic polarization that puts democracy itself at risk. In the U.S., liberal-leftists and conservative-rightists differ in many attitudes, values, and personality traits, as well as tendencies to justify the unequal status quo and embrace authoritarian aggression and group-based dominance. Some of these differences imply that conflict between liberal-leftists and conservative-rightists is tantamount to a struggle for and against democratic ideals. However, these political and psychological differences between the left and the right do not necessarily mean that Americans are forever doomed to intergroup hatred and intractable political conflict. Some modest basis for optimism emerges from recent experimental interventions, including one that encourages people to identify with and justify the system of liberal democracy in the U.S.
