![]() ![]() It doesn’t necessarily matter, though – the important thing wasn’t why the students were smiling, just that they were doing so with gusto. So there’s no way to know for sure whether people are giving genuine smiles of happiness and amusement, or if they’re simply in a pose during their picture. But Seder mentioned that new research indicates as many as 60 percent of people can fake a Duchenne smile. And it’s presumed based on a good bit on research from a lot of respected researchers, that you couldn’t fake an authentic smile, that researchers could tell because your mouth and eye muscles that would be constricting would not be of maximum intensity,” Seder says. In psych literature there’s something called a Duchenne smile, named after a guy named Duchenne, it’s a term used to describe a genuine smile, an authentic smile. Now, in terms of whether we could tell if people were faking smiles, that’s a complicated question. “We wanted to just find naturalistic photos. Each researcher graded the photos individually, and they used the mean score as a final intensity indicator. These two muscle movements were graded on a scale of one to five by the team and then added together. One of the muscle units produces raised cheeks and squinting, while the other creates a smile by lifting the corners of the mouth. Duchenne smileīut how do you determine the intensity of one’s smile, exactly? The researchers used a procedure to code the grins in the photos based on two muscle units on the face. To boil it down, the students with bigger grins in Facebook photos posted at the beginning of college reported more life satisfaction both during the time period they posted the photos, and at the end of their college careers. They also found that they could predict whether these students would increase their reported well-being based on the smile intensity. They found that the students who had the most intense smiles in their profile pictures during the first semester of school reported more happiness both in that first semester as well as 3.5 years later. The researchers checked back in with their subjects at the end of their college careers and looked at their contentment levels again. They measured the intensity of the sample groups’ smiles after taking them through a series of tests to gauge their general well-being and levels of extroversion. They selected users were freshman in their first semester at the University of Virginia, and had profile picture photographs that could be analyzed for smile intensity. The researchers looked at two groups of Facebook users, taking their first assessments in 20. So Seder and the rest of the research team decided to do just that – with a little help from today’s yearbook photo: Facebook profile pictures. “But they didn’t do that, they just looked at the overall score.” “What would’ve been ideal was if they had looked at the initial well-being reports those women gave and then compared them to the reports of changes over time,” says Seder. However, the study didn’t look at how the initial “well-being” assessments compared to the results down the line, so they didn’t map how the subjects’ happiness levels changed over time. The photo subjects’ agreed to complete follow-up surveys they’d receive in the mail every eight to 10 years so researchers could assess what the predictive potential of those college photos. The previous study was done by researchers at a college in California who analyzed college yearbook graduation photos from 19. The project takes inspiration from an earlier study based on yearbook photos. “You’re making a choice to continue to endorse that representation of yourself as part of your public persona on Facebook.” ![]()
