Concept and characteristics
Skitka and colleagues (2005) showed that people holding the same position on an issue differ psychologically depending on whether they see it as a moral matter. Moral conviction had unique effects not explained by general indices of attitude strength such as extremity, importance and certainty. People with strong moral conviction wanted more social and physical distance from those who disagreed, and groups with differing views had difficulty reaching agreement. Skitka (2010) identified universality, objectivity, independence from authority, strong emotion and motivation to act as characteristics of moral conviction.
The moral mandate effect
Skitka and Mullen (2002) studied the case of Elián González, the Cuban boy returned to Cuba. People with strong moral conviction about the case judged the government's decision fair or unfair according to whether the outcome matched their position rather than whether the procedure was fair. This is called the moral mandate effect. Mullen and Skitka (2006) showed that it stems from anger at undesired outcomes. It implies that the common expectation that fair procedures resolve conflict may not hold for moral issues.
Political consequences
Skitka and Bauman (2008) showed that in U.S. presidential elections, people with stronger moral conviction about their candidate preference were more likely to vote. Moral conviction drives social movements and political participation. On the other hand, Skitka and colleagues (2021) concluded that stronger moral conviction is linked to intolerance of opposing views, refusal to compromise and acceptance of violence or rule-breaking to achieve ends. The concept is used together with sacred values and moral foundations theory to explain affective polarization.
