What kind of rationalization is system justification?

Cushman uses rationalization to refer to people's explanations for their own actions. In system justification theory, scholars use the same term to refer to people's efforts to cast their current status quo in an exaggeratedly positive light. We try to reconcile these two meanings, positing that system justification could result from people trying to explain their own failure to take action to combat inequality. We highlight two novel and contested predictions emerging from this interpretation.
