Amid heightened political polarization in the United States, have politics worked their way into the bedroom? An increase in political similarity between romantic partners has consequences not just for romantic relationships but for society as a whole; political homophily increases our political echo chambers and affects future generations. We drew upon 11 data sets with over 4,000 individuals (including more than 500 couples) to test four preregistered research questions about the prevalence, correlates, consequences, and potential buffers of political dissimilarity in modern-day relationships. Across measures of similarity (overall perceptions, partisanship matching, shared political ideology), couples in our sample showed high levels of political similarity (e.g., 23% were cross-partisan, with fewer than 8% composed of one Democrat and one Republican). Examining 18 potential correlates of political dissimilarity, we found little evidence that certain factors predispose people to end up in a politically dissimilar relationship. When considering the potential consequences of political dissimilarity, we found a small association between political dissimilarity and relationship quality in general and in daily life. The effect was evident when examining perceived political dissimilarity (over and above perceptions of overall similarity) and, to a lesser extent, dissimilarity in terms of partisanship and political ideology. Prosocial processes such as appreciation and perspective-taking may moderate these effects. Taken together, these findings speak to the need to further consider the ways in which the sociopolitical context is shaping the formation and maintenance of close relationships.

我爱你，但我讨厌你的政治：政治差异在浪漫关系中的作用。


在美国政治两极分化加剧的情况下，政治是否已经进入了卧室？浪漫伴侣之间政治相似性的增加不仅会对浪漫关系产生影响，也会对整个社会产生影响。政治同质性增加了我们的政治回声室并影响了子孙后代。我们利用 4,000 多人（包括 500 多对夫妇）的 11 个数据集来测试四个预先登记的研究问题，这些问题涉及现代关系中政治差异的普遍性、相关性、后果和潜在缓冲。在相似性衡量标准（总体看法、党派匹配、共同的政治意识形态）方面，我们样本中的夫妻表现出高度的政治相似性（例如，23% 的夫妻是跨党派的，其中只有不到 8% 的夫妻是一名民主党人和一名共和党人）。通过考察政治差异的 18 个潜在相关因素，我们发现几乎没有证据表明某些因素容易导致人们最终陷入政治差异关系。在考虑政治差异的潜在后果时，我们发现政治差异与一般和日常生活中的关系质量之间存在微小关联。当考察感知到的政治差异（除了对总体相似性的看法）以及较小程度的党派偏见和政治意识形态方面的差异时，这种效果是显而易见的。欣赏和换位思考等亲社会过程可能会缓和这些影响。总而言之，这些发现表明需要进一步考虑社会政治背景如何影响亲密关系的形成和维持。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
