Body Symmetry and Perceived Sexual Attractiveness
Symmetry is the evenness of features in an object, such as a face. This is measured by dividing the distance between one feature from its opposite feature by the average distance between those same features across all individuals of that species. Researchers have found that humans are more likely to find symmetrical faces more attractive than asymmetrical ones.
Several studies have been done to determine the effects of facial symmetry on perceived attractiveness. One study involved taking pictures of women's faces, enlarging certain sections of them, and then having men rate their perceived attractiveness. The results showed that symmetrical facial features were consistently rated higher. Another study had participants look at photos of pairs of twins, one with symmetrical features and the other with less so, and asked them which they thought was more attractive. Again, the symmetry of the faces played a role in how attractive they appeared.
The reason for this preference may be due to biological factors. Humans can subconsciously recognize symmetry as a sign of good genetics, which suggests health and fitness. Asymmetry could indicate disease or injury, making it undesirable for mating purposes.
Symmetry is often associated with beauty standards throughout history and culture, further reinforcing its importance in perceptions of attractiveness.
There are some caveats to this generalization.
Research has shown that people of different ethnicities and cultures may not share the same views on what constitutes attractiveness.
Some studies suggest that certain facial features, such as wide-set eyes and high cheekbones, are more important than overall symmetry when it comes to sexual attraction.
Body symmetry appears to play an important role in how we perceive sexual attractiveness. While there are nuances and exceptions, the idea that symmetrical features are seen as more desirable holds true across many contexts and cultures. This preference may have evolved due to its association with healthy and fit individuals, as well as cultural ideals of beauty.
How does body symmetry influence perceived sexual attractiveness?
In general, symmetrical physical features are considered more attractive than asymmetrical ones. This perception is rooted in evolutionary biology, as it indicates that the individual has had no major health issues during development. People who are more symmetrical tend to be seen as healthier and stronger, which makes them better candidates for mating and reproduction.
