Smile If You Love Your Future Relationships

smileFrom Live Science, here’s an interesting summary by Clara Moskowitz of recent research suggesting that “Smiles Predict Marriage Success.”  Here are some excerpts.

If you want to know whether your marriage will survive, look at your spouse’s yearbook photos.

Psychologists have found that how much people smile in old photographs can predict their later success in marriage.

In one test, the researchers looked at people’s college yearbook photos, and rated their smile intensity from 1 to 10. None of the people who fell within the top 10 percent of smile strength had divorced, while within the bottom 10 percent of smilers, almost one in four had had a marriage that ended, the researchers say. (Scoring was based on the stretch in two muscles: one that pulls up on the mouth, and one that creates wrinkles around the eyes.)

In a second trial, the research team asked people over age 65 to provide photos from their childhood (the average age in the pictures was 10 years old). The researchers scored each person’s smile, and found that only 11 percent of the biggest smilers had been divorced, while 31 percent of the frowners had experienced a broken marriage.

Overall, the results indicate that people who frown in photos are five times more likely to get a divorce than people who smile.

While the connection is striking, the researchers stress that they can’t conclude anything about the cause of the correlation.

“Maybe smiling represents a positive disposition towards life,” said study leader Matthew Hertenstein, a psychologist at DePauw University in Indiana. “Or maybe smiling people attract other happier people, and the combination may lead to a greater likelihood of a long-lasting marriage. We don’t really know for sure what’s causing it.”

Hertenstein said he has considered other explanations, such as the possibility that people who smile more often tend to attract more friends, and a larger support network makes it easier to keep a marriage healthy. Or it could be that people who smile when a photographer tells them to are more likely to have obedient personalities, which could make marriage easier.

The results of the study fit into a larger pattern of research that has found many personality characteristics can be determined from very thin slices of behavior. Basically, we often reveal ourselves in the most subtle, simple ways.

    Though everyone smiles, people from different cultures, different social locations, different historical periods ascribe different meanings to smiling (and the actual smile, the muscular event that we call smiling, varies with time and place as well). Middle Americans smile more often, and sustain their (characteristically American, and even middle class) smiles for a longer period of time than, say, Icelanders. And Icelanders often consider excessive smiling as inappropriate, perhaps ridiculous, and, in general, undesirable. Hence, McDonald’s trouble to train their Icelandic cashiers to flash those wining and protracted American smiles right and left throughout their eight hour shift. Look at the official portraits of the US presidents in chronological order and you will see that the smiling curb starts peaking only from the middle of the 20 century on. There is a history to the meaning of smiling. And smiling is hence a sort of intermediate variable that often points not toward universal affects, but toward an array of cultural meanings that tend to change from place to place and from time to time. Thus, just as lighter ownership is not the true predictor of cancer (though having a lighter in your pocket points toward possible cancer outcomes), smiling is not at all a true predictor of marriage stability. This predictor stands behind the smile, and it includes psychological, cultural, and historical conditionbs that seem to be completely outside the scope of this study.

    I love that photo of smiley faces in your post. Could you tell me where you got it. I would love to use it as my profile pic in a new twitter account. Just wanted to ask your permission if it’s your shot.
