Researchers have long known that there is a standard of beauty that crosses all cultural boundaries - that of symmetry - the more symmetrical the face the more it's consider beautiful. So, the obvious mathematical consequence is that if you average a whole bunch of faces, you get a lot more symmetry as the grand total average. This concept is taught in most university intro psychology courses. Now with digital imaging techniques, they were able to really test this finding a lot easier. In "our days" they had to use slide transparencies and overlay multiple faces to show us examples. Here's an article from 2006 from Boston University with less number of faces averaged: http://www.bu.edu/phpbin/news-cms/news/?dept=1127&id=41272

BRIAN (01.10.14, 2:14 PM): If you look at their website, faceResearch.org there is a demo that you can click on different faces and merge them. I did 49 different women of different races and it came out as a very beautiful woman. The hair was a little funky but the face was great.
