What is beauty?

The characterization of a person as “beautiful”, whether on an individual basis or by community consensus, is often based on some combination of Inner Beauty, which includes psychological factors such as personality, intelligence, grace, congeniality, charm, integrity, congruity and elegance, and Outer Beauty, (i.e. physical attractiveness) which includes physical factors, such as health, youthfulness, sexiness, symmetry, averageness, and complexion.

A common way to measure outer beauty, as based on community consensus, or general opinion, is to stage a beauty pageant, such as Miss Universe. Inner beauty, however, is more difficult to quantify, though beauty pageants often claim to take this into consideration as well.

A strong indicator of physical beauty is "averageness", or "koinophilia". When images of human faces are averaged together to form a composite image, they become progressively closer to the "ideal" image and are perceived as more attractive. This was first noticed in 1883, when Francis Galton, cousin of Charles Darwin, overlaid photographic composite images of the faces of vegetarians and criminals to see if there was a typical facial appearance for each. When doing this, he noticed that the composite images were more attractive compared to any of the individual images. Researchers have replicated the result under more controlled conditions and found that the computer generated, mathematical average of a series of faces is rated more favorably than individual faces.[8] Evolutionarily it makes logical sense that sexual creatures should be attracted to mates who possess predominantly common or average features.[9]

Another feature of beautiful women that has been explored by researchers is a waist-to-hip ratio of approximately 0.70 for women. Physiologists have shown that this ratio accurately indicates most women's fertility. Weight and skin color often govern attractiveness in a way dependent on one's culture[10] Beauty is not solely limited to the female gender. More often defined as 'bishōnen,' the concept of beauty in men has been particularly established throughout history in East Asia, and most notably, in Japan. This is distinct from the idea of being metrosexual, which focuses mainly on the behavior of men in traditionally feminine ways. Bishōnen refers to males with distinctly feminine features, physical characteristics establishing the standard of beauty in Japan and typically exhibited in their pop culture idols. The origin of such a preference is uncertain but it clearly exists even today.


Inner beauty
Inner beauty is a concept used to describe the positive aspects of something that is not physically observable.

While most species use physical traits and pheromones to attract mates, some humans claim to rely on the inner beauty of their choices. Qualities including kindness, sensitivity, tenderness or compassion, creativity and intelligence have been said to be desirable since antiquity.
