The preference for a romantic partner with the same political views is driven more by a dislike of the other side than by an attraction to like-minded people. "Democratic women are more likely than any other gender/party group to treat out-party membership as a relationship deal-breaker."
A growing body of work shows that partisan divides have increasingly bled into nonpolitical domains, including friendships and romantic relationships. This study [N = 1483 young adults] uses a conjoint survey experiment to assess the importance of shared partisanship for long-term partner preferences.
The research suggests that individuals, particularly partisans, tend to prefer romantic partners who share their political party affiliation. This preference is largely driven by a negative form of partisanship, an aversion to those in the opposing party, rather than a strong positive attraction to one's own party. Focusing on white partisans, we find that Democratic women are more likely than any other gender/party group to treat out-party membership as a relationship deal-breaker.
[More about the study by Google AI]: [The study indicates that individuals are more likely to be turned off by those who belong to a different political party than they are to be attracted to those in their own party. The study also suggests that party affiliation can influence perceptions of physical attractiveness, with partisans rating individuals with opposing political views as less attractive. This preference for political homogeneity in relationships can have significant implications for social dynamics, potentially leading to fewer cross-party relationships and further reinforcing political polarization.]
My favorite culture from antiquity, the enchanting Minoans, famous for their extraordinary stylishness and aesthetic sensibility, already had a thing for flowers, like in that illustrious "spring" fresco.
