This is a little touchy because I don't think people are comfortable with the word "average" when it comes to beauty. The results of the images have some upset because the "average" face of women from around the world are actually all quite beautiful. Some think maybe too beautiful to be accurate. Nevertheless, it's an interesting project by FaceResearch.org
. Apparently, there's no information on how the models were selected or from what I can see even how many were used. It'd be interesting to see one done where more of the statical data and original images were available.
