Just World, Trust in Institutions and Socioeconomic and Political Moderations

Abstract This study investigates the system justifying role through belief in a just world (BJW), testing whether institutional trust is related to this belief and whether this relationship depends on specific socioeconomic and political factors. A research with 381 university students, aged 18 to 64 years (M = 22.4, SD = 6.25), explored their BJW and their degree of institutional trust. Regression and moderation analyses revealed that BJW relates to institutional trust only in left-wing and with lower income participants. We believe this occurs because they need more an ideology that justifies the system to trust the institutions. This phenomenon can prevent these people from pursuing structural social changes since the system is now seen as fair.
