What does it matter which side of your face you show when you're having your photograph taken? A team of scientists say that it reflects how much you see yourself as emotional and arty or rational and scientific. Owen Churches and his colleagues analysed the personal webpages belonging to 5,829 English-language university academics around the world. They found that engineers, mathematicians and chemists more often posed with their right cheek; English lit. dons and psychologists with their left. "... [M]ost academic psychologists, who may have entered the profession during its arts oriented past, perceive themselves as being more akin to arts academics than scientists," said Churches and co.

The researchers made their observations after choosing 30 universities at random from the 200 listed by the Times Higher Education World University Rankings for 2010 to 2011. When they found scholarly departments where the convention was for academics to present a photo of themselves, they went on to analyse all academic photos to see which cheek was visible. Straight-on photos were ignored. That left 3168 photos for analysis. Consistent with previous research there was a strong effect of sex - women more often pose with their left cheek showing. But the differences between the arts and science academics held even after controlling for this confound. The contrast also survived an analysis that excluded any photos that looked like they'd been taken by a professional photographer.

In the current study, the general pattern of cheek posing and academic affiliation broke down when it came to fine arts and performing arts - they showed no bias for posing with their left side. The researchers speculated this may be because of their expert knowledge of the history of portraiture.

Critics may wonder about the researchers' interpretation that the posing position of psychologists suggests they identify with the arts. This seems quite a leap from the data that's available. It's also worth noting that there's a huge amount of variation within each academic discipline in posing position. Even among male engineers, for example, nearly 40 per cent posed with their left side facing the camera.

"Academics be warned," the researchers concluded. "We present ourselves to our students and colleagues in our profile pictures and the way we do so may reveal more about ourselves than we think."

Can photos show if one is likely to participate in a study in addition to if he or she is knowledgeable?

I often look at photos after reading bios while searching for potential candidates to participate in a particular study. After I conduct a study, maybe I should consider returning and viewing photos of the participants and non participants and compare their photos based on their responses.
