Averageness

In attractiveness studies, averageness is one of the characteristics of physical beauty in which the average phenotype, i.e. outward appearance, of the individual theoretically characterizes averaged genotypes, thus indicating health and fertility. The majority of averageness studies and theories have to do with photographic overlay studies, in which images are morphed together. Other factors involved in measuring attractiveness are symmetry, youthfulness and similarity (like-attracts-like).
