For one study, researchers recruited 49 Wisconsin legislative aides to rate the attractiveness of different politicians. Sure enough, participants rated the leaders as more attractive if they aligned with their political commitments (Republican or Democrat).
“In contrast with research traditions that treat physical attractiveness as a static trait, our findings highlight the importance of group membership as a lens for perceiving familiar leaders’ physical attractiveness,” concluded lead author Kevin Kniffin and his colleagues.
