Replication Data for: When Common Identities Decrease Trust: An Experimental Study of Partisan Women

How does sharing a common gender identity affect the relationship between Democratic and Republican women? Social psychological work suggests that common ingroup identities unite competing factions. After closely examining the conditions upon which the Common Ingroup Identity Model depends, I argue that opposing partisans who share the superordinate identity of being a woman will not reduce their intergroup biases. Instead, I predict that raising the salience of their gender will increase cross-party biases. I support my hypotheses with a nationally representative survey of 3,000 adult women and two survey experiments, each with over 1000 adult women. These findings have direct implications for how women evaluate one another in contentious political settings and, more broadly, for our understanding of when we can and cannot rely upon common identities to bridge the partisan divide.

共享同一性别身份会如何影响民主党女性与共和党女性之间的关系？现有社会心理学研究表明，共同内群体身份能够凝聚相互竞争的派系。在细致考察共同内群体身份模型（Common Ingroup Identity Model）所依赖的前提条件后，本文提出：即便同属对立党派阵营的女性共享“女性”这一上位身份，她们也不会削弱彼此间的群体间偏见。与之相反，本文预测提升性别身份的凸显性，反而会加剧跨党派偏见。本文通过一项覆盖3000名成年女性的全国代表性抽样调查，以及两项各包含1000余名成年女性的调查实验，验证了所提出的研究假设。本研究结论不仅对女性在充满争议的政治场景中如何评价彼此具有直接启示意义，更从更广泛的层面，帮助我们理解何时能够依托共同身份弥合党派分歧，以及何时无法做到这一点。
