Facial symmetry is one specific measure of bodily asymmetry. Along with traits such as averageness and youthfulness it influences judgments of aesthetic traits of physical attractiveness and beauty. For instance, in mate selection, people have been shown to have a preference of symmetry. This is due to the fact that it is seen an indicator of health and genetic fitness, but also as holding adaptation qualities; reflecting the ability to withstand the changes in their environments.

Facial symmetry has been suggested as a possible physical manifestation of the ‘big-five’ personality traits. The most consistent finding is that facial symmetry is positively correlated with extraversion, indicating that individuals with more symmetric faces are also more extroverted. More symmetrical faces are also judged to be lower on neuroticism but higher on conscientiousness and agreeableness. More symmetrical faces are also more likely to have more desirable social attributes assigned to them, such as sociable, intelligent or lively.

Recent study shows the association of trustworthiness and with symmetry on the face. People are biologically evolved to detect the deceptive intention of other people by observing the asymmetry in the face. When people are lying, their facial muscles become imbalanced.

Example of trustworthy (on the left) and untrustworthy (on the right) looking male faces. These faces were created by morphing two of the most trustworthy and untrustworthy, respectively, looking male faces in our sample.

I wish I could morph faces of trustworthy and untrustworthy Philippine politicians and check the results.
