Of course, in the United States and many other countries, smiling is a common, reflexive gesture of goodwill.
There is, indeed, truth to the “smiling gap”: In our psychology research, we’ve noticed a striking difference in how often people smile in the United States when compared to Russia. To Americans, it might be easy to assume that this says something about Russians — that they’re an unfriendly, callous people.
But that’s not the case at all. Instead, it’s worth looking at why certain expressions, such as smiling, become a key part of social exchanges in some cultures and not others.
As far as we can tell, there are two likely explanations for the smiling gap.
The first has to do with how people in different cultures communicate with one another. Different cultures have different “display rules,” or norms that dictate how individuals should express themselves.
Display rules are often governed by something called social distance, which refers to the expectation of privacy in a given culture. Studies have found that in Russia, social distance is lower relative to the United States, meaning that people generally expect to be approached by strangers and there’s more mutual understanding. There’s less pressure to display a positive emotion like smiling to signal friendliness or openness, because it’s generally assumed you’re already on the same wavelength.
When there’s greater social distance, there’s more wiggle room to get into trouble during a chance encounter. Because Americans expect a modicum of privacy even when out in public, strangers approach one another less frequently. When it does happen, it can be anxiety-inducing.
So when approaching a stranger, a smile can grease the social wheels of the interaction and help the other person feel at ease.
Second, this phenomenon can be viewed through the lens of cross-cultural differences in personality or temperament. We know that different cultures have different ways of experiencing, expressing and regulating their emotions.
For example, in our work, we’ve traced how kids in different cultures develop different temperaments.
In one series of studies with Helena Slobodskaya, a psychologist at Novosibirsk State University Research Institute of Physiology and Basic Medicine, we found that mothers in Russia, compared to American caregivers, reported that their infants and toddlers were more likely to demonstrate negative emotions such as anger or frustration. The Russian mothers also reported that their young children exhibited lower levels of positive emotional expression, including smiling and laughter.
There’s an interesting twist to these findings. The American toddlers who were most likely to express positive emotions also were better at self-regulation. In other words, they were better at controlling their emotions and behaviors. But Russian toddlers’ inclination to express positive emotions had no such relationship to self-control.
In each culture, smiles work in different ways. In Russia, children may contract their facial muscles only when they’re truly happy. It’s an authentic expression of emotion.
In the United States, however, kids may develop an understanding that smiling is an important social cue — one that doesn’t necessarily reflect how they truly feel but instead signals acknowledgment or appreciation of another person. And this might explain why American kids who smile more also tend to have more self-control.
Next, the attitudes and beliefs of adults could play a role. American parents may think that children who express themselves in positive ways also possess other beneficial attributes, such as the ability to focus and control their behavior.
In other words, in the United States, a happy child is perceived as a “good” child. Russian caregivers, on the other hand, don’t see any link between a kid who smiles a lot and his or her manners and behavior. So as these kids grow up, they’re less likely to smile in everyday social interactions.
Nonetheless, until the tournament ends, many foreign soccer fans will be gawking and smiling during every food order and request for directions. In response, many Russians will be gritting their teeth — and putting on their happy faces.
