Intraminority solidarity research has previously focused on how similarities in discrimination experiences can facilitate stigma-based solidarity. Yet, research on a lay theory of generalized prejudice has demonstrated that people tend to perceive attitudes towards stigmatized social groups as co-occurring. Integrating these lines of research, the present studies sought to examine if the extent to which prejudices are perceived to co-occur can facilitate stigma-based solidarity for marginalized social groups, and in turn promote interest in coalitional justice. Recruiting heterosexual Black Americans (Study 1), White women (Studies 2–3), and White men (Study 4), the present research demonstrates that perceiving prejudices as co-occurring increases stigma-based solidarity that in turn produces greater interest in coalitional justice efforts that include the ingroup. The present findings demonstrate the importance of focusing on beliefs about perpetrators’ attitudes when examining intraminority solidarity and highlight the limitations of a lay theory of generalized prejudice to fight prejudices broadly.

以前，少数民族内部团结研究的重点是歧视经历的相似性如何促进基于污名的团结。然而，关于普遍偏见的外行理论的研究表明，人们倾向于认为对被污名化的社会群体的态度是同时发生的。结合这些研究方向，本研究试图检验偏见被认为同时发生的程度是否可以促进边缘化社会群体基于耻辱的团结，进而促进对联合正义的兴趣。招募异性恋美国黑人（研究 1）、白人女性（研究 2-3）和白人男性（研究 4），目前的研究表明，将偏见视为共同发生会增加基于耻辱的团结，从而对包括内群体在内的联合司法努力产生更大的兴趣。目前的研究结果表明，在检查少数群体内的团结时，关注对肇事者态度的信念的重要性，并强调广义偏见的外行理论在广泛打击偏见方面的局限性。
