Political orientation and system justification: the moderating role of national identity in a Spanish sample ( Orientación política y justificación del sistema: el rol moderador de la identidad nacional en una muestra española )

Abstract

Right-wing people usually justify the system more than left-wing people. The social identity approach suggests that system justification may be an ingroup bias at overarching national levels and that differences between leftists and rightists could be linked to differences in party norms in promoting national identification. A cross-sectional design was used in which 192 adults (64.6% men, mean age of 35.61 years) were enrolled. Political orientation, national identification and general and economic system justification were collected. Results from structural equation modelling indicated that rightists, as compared with leftists, were higher in national identification and both general and economic system justification. National identification mostly mediated the relationship between political orientation and general system justification, while mediation on the relationship between political orientation and economic system justification was less marked. The social identity approach expectation that differences in system justification could be linked to the extent to which people identify with their overarching social category appears to be supported.
