Mate choice influenced by others

By Elizabeth Landau
CNN.com Health Writer/Producer

You may have found a celebrity more attractive after reading that he or she is in a good relationship. Or maybe you've paid a little more attention to someone in your social circle after you've seen a significant other on his or her arm.

A new study in the journal Evolution and Human Behavior suggests that humans, like fish and birds, engage in "mate copying," meaning another person's successful search for a partner can influence your own mate preference.

Researchers looked at 40 men and 40 women - a relatively small sample size. First, participants rated photos of eight members of the opposite sex in terms of their potential for a short-term or long-term relationship. Then, people in the study watched videos of each person they had rated interact with someone else in a speed date.

Participants judged how romantically interested the daters were in each other in each interaction, and then re-rated the person of the opposite sex based on short-term and long-term relationships.

Researchers found that participants were likely to rate daters higher who had been on what they deemed a successful date - an example of mate copying.

"Our results suggest that both men and women are influenced by social information when making both short-term and long-term relationship attractiveness judgments," the authors said.

There were some noticeable gender differences, however. Men showed an increase in relationship interest regardless of how they judged the interaction of the date; women, on the hand, had a diminished interest when they perceived that the daters were not interested in each other. They upped their relationship rating for the man in the example only when the individuals appeared to be mutually interested.

    Really? When I see someone on a date or in a relationship, I view them as not available, not more attractive. Strange

    So really, this study showed that men are always interested in women, whereas women's interest in men increases when they seem to possess at least some emotional depth. I disagree (based on the info here) that the conclusion is that people (women) are likely to mate-copy. To me, it shows that when an attractive man turns out to be a personality dud, a woman moves on. Didn't we already know this?

    Viewing a video of a person regardless of whether they are interacting on a date or just talking is enough to influence a person's opinion of them more so than a still photo.

    Its nice to know that Cancer, AIDS, MS, and every other debilitating disease has been cured and our top minds can now spend their time researching the best chance to getting laid.

    I'm not surprised and could have predicted this result. Have you ever noticed that when a woman divorces a man she doesn't want anyone else to have him. However, generally when another female shows interest she will decide to either hate his guts or take him back.

    This just in...people often become more or less attracted to a person after finding out more about them...

    Wow, some real stretches are made with these findings. That sample size is less than 1/4 of guys and girls at my neighborhood bar on a Wednesday night here in Tampa.
    Just as men showed an increase in relationship interest regardless of how they judged the interactions, women on the other hand had a diminished interest when they perceived the daters were not interested in each other. This is an example of Social Value, plain and simple; women are unconsciously attracted to a man if another woman finds him attractive and without even understanding why they do the opposite – consider him to be less attractive, i.e., less valuable to her, because another woman indicated she doesn't like him.
    Men don't work this way – they base their attraction towards another woman far less on social value than on other factors, that's why there are always several guys for every girl, regardless of any other qualities she may possess other than being a female.
    I don't know where they come up the term "mate copying," but it sounds like marketing hype and a catchey way to try to explain why women will Always want a guy who other women value (attractive).

    Seems to be a slighlty different take on what other researchers, and just plain attention to everyday human behavior, have shown. Women are more attracted to married/attached men than they are single men. Men are usually less attracted to married/attached women.

    That may mostly may be true for certain young women with less experience at relationships who respond more readily to peer trends, but more mature women and most men will base their selections solely on attraction and compatibility and in effect put someone who seems to be already emotionally involved on the back burner.

    Phil-So you're telling us that we we shouldn't have sex, just sit around wondering why and when we're going to get sick??

    "Wait!" The study isn't over until they start assigning personality types to the subjects. They should have also gotten a preference baseline to expose biases. I'm sure that pretty girls are always good for the short term even if they are a zombie. LOL, Now that we all know the underlying influences and intricacies of social interaction we can move on with confidence. LOL

    Women see a man who IS desired as being desirable. They take cues from other women. Anyone who has taken psychology already knew this. All this article shows is that the journal Evolution and Human Behavior is a joke, doing studies on already known facts, and that they should not be called "researchers."

    Junio – read more carefully... it states women became LESS interested when they found out more, and the date did not go well.

    Coincidentally, there are a news story in the business section about how HR departments typically rank the unemployed lower than the already successfully employed. "Thou shalt hit those who already have been hit again and again" apparently works for a typical anti-compassionate human.

    Odd most people want what they cant have. so if someone is in a relationship, they want them and when they get them, they dont want them anymore. its all about the chase.

    Um this study is ridiculous. What are they going to, increase their opinion of the people who had "bad" dates? When you're only given one criteria to judge a group by, of course you're going to favor the more successful ones, regardless of what that criteria is. If there were videos of these people mowing the lawn, the opinion would increase for those who mowed the lawn the best. It has to be compared to other equally important factors such as looks and income and personality, for it to be meaningful at all.

    This is simply not the case for me...as I tend to follow my own standards when choosing a mate. I come from a father and mother
    who have been married for many years...in fact too many I sometimes
    think. So stability is a definite factor for me, Im not at all influenced
    by what others may have to say or think...or by seeing the person thru
    different eyes supposing they were with someone else. I just think
    its an individual thing( at least for me)... For some I also think being
    alone for a long time tends to hasten your decision especially if the
    other person says and does what you want them to do....No one really
    wants to live alone in this world...everyone wants to be in that special
    relationship where the rest of the world envys you.

    Every guy knows that the best "bait" for attracting women is an attractive woman.

      Or maybe it's not being a manipulative punk. Women can see through BS far easier than you think.
