ABSTRACT

System justification theory (SJT) assumes that social identity theory (SIT) cannot fully account for system justification by members of low-status (disadvantaged) groups. Contrary to this claim, we provide several elaborations of SIT that explain when and why members of low-status groups show system justification independent from any separate system justification motive. According to the social identity model of system attitudes (SIMSA), the needs for social accuracy and a positively distinct social identity fully account for system justification by members of low-status groups. In the present article, we (a) explain SIMSA’s accounts of system justification, (b) develop associated hypotheses, (c) summarise evidence that supports each hypothesis, and (d) highlight issues to be addressed in future research. We conclude that SIMSA provides a more parsimonious explanation of system justification by the disadvantaged than SJT, because it does not refer to an additional separate system justification motive.

摘要

系统合理性理论（SJT）假设社会认同理论（SIT）不能完全解释低地位（弱势）群体成员的系统合理性。与这一主张相反，我们对 SIT 进行了一些阐述，解释了低地位群体的成员何时以及为何表现出独立于任何单独的系统正当理由动机的系统正当理由。根据制度态度的社会认同模型（SIMSA），对社会准确性和明确的社会认同的需求充分考虑了低地位群体成员的制度正当性。在本文中，我们 (a) 解释 SIMSA 对系统论证的说明，(b) 提出相关假设，(c) 总结支持每个假设的证据，以及 (d) 强调未来研究中需要解决的问题。
