If you disagree with someone's political preferences
Talk about the personal becoming political.
A 2016 paper, published by researchers at the University of California, Merced and California State University, Stanislaus suggests that our political views influence who we find attractive.
For the study, which was conducted during the 2012 presidential election, about 850 US adults indicated whether they identified more strongly with the Democratic or Republican party.
Then, participants looked at a photo and brief bio of a person of the opposite gender. In some cases, the bio indicated whether the person supported Barack Obama or Mitt Romney.
As it turns out, female Democrats found the man pictured much more attractive when he was an Obama supporter and much less attractive when he was a Romney supporter.
Men also found the woman much less attractive when she supported the opposite party. But they didn't find the woman that much more attractive when she supported the same party.
This isn't a reason to change your political affiliation so that someone finds you more attractive, of course. It's simply evidence of the myriad factors that shape our dating preferences.
