"If they are much better-looking than you, you are worried about them going off and having affairs.
If they are much less attractive, you are worried that you could do better." A 2010 study from the University of Wales Institute found that men pictured with a Silver Bentley Continental GT were perceived as way more attractive than those pictures with a Red Ford Fiesta ST.
As psychologist and writer Scott Barry Kaufman notes, the halo effect works in other ways too.
In a 2014 Chinese study, more than 100 young people looked at images of men and women's faces and rated them on attractiveness.
Each face pictured was paired with a word that described either a positive personality trait — like kindness or honesty — or a negative personality trait, like being evil or mean.
Results showed that the people described with positive traits were rated more attractive.
In a 2013 study from researchers at the University of New South Wales, researchers had 177 heterosexual men and 351 heterosexual women look at images of 10 men in one of four conditions: clean-shaven, light stubble, heavy stubble, or full beard.Participants rated the men pictured on several traits, including attractiveness.That women said the most attractive beard length was heavy stubble. "An intermediate level of beardedness is most attractive," they add.And a 2014 study from Cardiff Metropolitan University found that men pictured in a luxury apartment were rated more attractive than those in a control group.Interestingly, men don't seem to be more attracted to women when they're pictured in a high-status context.Psychologists call it the "George Clooney Effect." As 2010 study of 3,770 heterosexual adults suggested that women often prefer older men.
