Academics turn the other cheek?

My nomination for the ig-Nobel prize:

It is now standard practice, at Universities around the world, for academics to place pictures of themselves on a personal profile page maintained as part of their University’s web-site. Here we investigated what these pictures reveal about the way academics see themselves.

Since there is an asymmetry in the degree to which emotional information is conveyed by the face, with the left side being more expressive than the right, we hypothesised that academics in the sciences would seek to pose as non-emotional rationalists and put their right cheek forward, while academics in the arts would express their emotionality and pose with the left cheek forward.

We sourced 5829 pictures of academics from their University websites and found that, consistent with the hypotheses, there was a significant difference in the direction of face posing between science academics and English academics with English academics showing a more leftward orientation. Academics in the Fine Arts and Performing Arts however, did not show the expected left cheek forward bias. We also analysed profile pictures of psychology academics and found a greater bias toward presenting the left check compared to science academics which makes psychologists appear more like arts academics than scientists. These findings indicate that the personal website pictures of academics mirror the cultural perceptions of emotional expressiveness across disciplines.

I am facing forward in my picture. Never thought to psychoanalyze that before…

  1. Are most pictures professionally done? If so how much that falls onto the photographer positioning them that way? Not sure what to make of this….

  2. I would expect mathematicians and the most “hard” or “pure research” or “just the facts” scientists to face straight forward, due to being trained not to care about appearances and to avoid bias. You know, except when the photographer orders them to do otherwise.
