A critical review of the (un)conscious basis for system-supporting attitudes of the disadvantaged

Is support for societal systems amongst the disadvantaged driven by an (un)conscious system justification motive that is independent from self-interests? System justification theory (SJT) is unique in its affirmative answer to this question. SJT proposes (a) that support for societal systems operates in the service of maintaining the status quo, (b) that the evidence for this system justification motive lies with the fact that members of disadvantaged groups (un)consciously support societal systems that are detrimental to their interests, and (c) that these processes are most apparent when group interests are weak. The present article reviews emerging evidence for these propositions and concludes that (a) an unconscious manifestation of system justification is unlikely based on SJT's "strong" dissonance-based predictions, which assumes that competing group and system motives are cognitively salient, and (b) a conscious system justification motive is also unlikely amongst the disadvantaged when group interests are weak. In addition, we suggest ways in which to explain system justification effects amongst the disadvantaged without recourse to an (un)conscious system justification motive
