When and How Information About Economic Inequality Affects Attitudes Towards Redistribution

Perceived economic inequality is positively associated with public support for policies to reduce it. However, providing information about economic inequality does not necessarily motivate people to support redistributive policies. This inconsistency may be due to how people interpret the information about inequality. We argue that the interpretation of information about inequality differs between individuals as a function of the characteristics of the source and people’s ideologies. We conducted two experiments using an exploratory (N = 239) and confirmatory (N = 707) strategy. We found that attitudes toward redistribution increased when a seemingly neutral international institution (as opposed to a left-wing political party) provided information about economic inequality due to the credibility attributed to the source—but not due to power and familiarity. Moreover, the effect of providing information about inequality on support for redistribution (via source credibility) depended on people’s ideologies: it was positive and statistically significant for people who held more (vs. less) system-justifying beliefs. These findings contribute to understanding the interplay between social psychological processes, communication strategies, and attitudes toward redistribution.
