Have you ever wondered what the average French woman or Brazilian woman looks like? Scientists from the University of Aberdeen in Scotland have developed a computer algorithm for digitally averaging faces to come up with the "average" look of a woman in 40 different countries.
The images, generated by their website, FaceResearch.org, are digital composites of thousands of faces of women living in each of the countries listed. (The blurry borders are due to the fact that the photos were centered around the "interpupillary distance" of the eyes.)
A few interesting points:
1. All of the women are attractive.
This is probably because blending many faces together makes the "mathematical mean" of the face symmetrical and blemish-free.
2. All of the women are young.
This is probably a selection bias issue, since younger women are more likely to have access to digital photography and the internet, and to participate in this type of project.
3. They have different expressions
The composites from Lebanon and Ukraine look stern, those from Germany and Brazil look neutral, and those from Thailand and India are smiling. This may reflect cultural attitudes and/ or social cues.
