I love you but I hate your politics: The role of political dissimilarity in romantic relationships.

Abstract

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.
