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 difers 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 confrmatory
(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 efect of providing information about inequality on support for redistribution (via source credibility)
depended on people’s ideologies: it was positive and statistically signifcant for people who held more (vs. less) system-justifying beliefs. These fndings contribute to
understanding the interplay between social psychological processes, communication
strategies, and attitudes toward redistribution.
