In some college class, I learned the fact that "averageness" in human faces was physically attractive. This seemed strange. Apparently though, if you take a bunch of humans of the same gender and compile their faces into one, you will end up with a good-looking person. And the more faces you compile, the better-looking our composite friend gets. The reason is that you are "averaging out" features of all different shapes and sizes and coming out with something very simple, very ordinary, and very symmetrical, and we are biologically programmed to find that attractive.
The main thing I took from this (and from the pictures below, which I found on the internet, which made me remember learning this, which made me decide to tell you about it) is that as much as our society influences the way we think and the things we like or dislike, our preference for attractive human faces have nothing to do with society or culture. Other aspects of appearance, such as pale versus tan, fat versus skinny, etc. are partially a product of our society. But not faces.
This is a weird and random entry, I know. But it's interesting.
The 1-10 scale for girls was so last year. I'm onto the 1-128 facial composite scale.
To see the faces compiling, one by one, click here and view the movie. Then click the link below the movie, and the number of faces will double.
