Social psychology’s search for ways to address intergroup inequality has grappled with two approaches that have been considered incompatible: (a) the prejudice reduction approach, that argues that changing individual negative attitudes will undermine the basis for discrimination and lead to intergroup harmony; and (b) the collective action approach, that argues that social protest and activism can improve the position of disadvantaged groups. The problem is that efforts toward prejudice reduction may serve to suppress genuine efforts to change. We propose the Achieving Multicultural Integration of Groups Across Society (AMIGAS) model, in which a multicultural commitment is proposed as a driver of both improved intergroup evaluations and promotion of collective action for reduced inequality, especially in contexts where there are conditions for a respectful intercultural dialogue. The AMIGAS model is a theoretical advance in the field of intergroup relations and a basis for implementing effective egalitarian policies and practices.

社会心理学在寻找解决群体间不平等的方法时遇到了两种被认为不相容的方法：(a) 减少偏见的方法，认为改变个人的消极态度将破坏歧视的基础并导致群体间的和谐；(b) 集体行动方法，认为社会抗议和激进主义可以改善弱势群体的地位。问题在于，减少偏见的努力可能会抑制真正的改变努力。我们提出实现跨社会群体的多元文化融合 (AMIGAS) 模型，其中多元文化承诺被提议作为改进群体间评估和促进集体行动以减少不平等的驱动因素，特别是在有条件进行相互尊重的跨文化对话的情况下。AMIGAS 模型是群体间关系领域的理论进步，也是实施有效的平等政策和实践的基础。
