Averageness
The finding that composite faces, blended from many photos, tend to be rated as attractive.
Also: average face effect
In 1990 the psychologists Judith Langlois and Lorri Roggman reported that faces made by digitally blending many photographs were rated more attractive than most of the single faces used. The effect, called averageness, has been repeated in many countries. Researchers suggest that familiar, central proportions are easy for the brain to process. The finding is about how people judge faces in experiments; it does not mean any real face is better or worse.
