From an old Beavis and Butt-head episode:
Butt-head: Whoa! This song's about like, some chick doing it with like, some other chick's boyfriend.Science chimes in:
Beavis: Yeah! That's pretty harsh.
Butt-head: Yeah. So like, this chick will only do yo if you like, already have a girlfriend...?
Beavis: Yeah, yeah! A lot of chicks are like that. They don't wanna go out with you unless you already have a girlfriend...but like, you can't get a girlfriend because you don't have a girlfriend...so it's like...struss-frating.
Men and women in the study were asked to describe their ideal romantic partner and were told they would be computer-matched with a like-minded student. Researchers told half of the participants that the person with whom they were matched was single. They told the other participants that their “match” was currently in a romantic relationship. Participants then answered a series of questions on how interested they would be in pursuing a relationship with their match.
Surprisingly [not so surprisingly - jeff], single women were much more interested in pursuing a relationship with a committed man than with a single man.
Specifically, when researchers described the man as single, 59 percent of single women were interested in pursuing him. However, when they described the exact same man as being in a committed relationship, 90 percent of the women were interested.
Men did not show this preference, and neither did women who were already in a relationship.
