In Simple Terms
A new study suggests that what makes a face attractive isn’t just symmetry. Faces that look more like the average face in a community are often seen as more appealing. This means that beauty might be linked to what we’re used to seeing and cultural expectations.
The Science Behind Attractiveness
For a long time, people believed that facial symmetry was the main factor in attractiveness. The human eye tends to be drawn to symmetrical faces, as they are thought to indicate good health and desirable genetic traits. However, a recent study led by Karel Kleisner challenges this idea, showing that symmetry is not the only factor influencing our perception of beauty.
The Scientific Approach to Studying Beauty
The study analyzed photographs of 1,550 people from ten different countries, including Brazil, Cameroon, Colombia, the Czech Republic, India, Namibia, Romania, Turkey, the United Kingdom, and Vietnam. The photos were taken in controlled environments to minimize external influences like lighting and background, allowing a focus on facial features.
Researchers used a technique called geometric morphometrics to measure facial characteristics, placing reference points around the eyes, nose, mouth, and jaw to accurately define the overall shape of the face. Attractiveness was rated on a seven-point scale by opposite-gender evaluators from the same culture.
The Importance of the Average Face
The surprising result of the study was that faces closer to the average shape within a group were considered more attractive. This suggests that attractiveness might be linked to familiarity with certain facial shapes within a culture, as the brain easily recognizes commonly repeated shapes.
The average shape does not necessarily mean a plain or unremarkable face; rather, it relates to the concept of repetition or familiarity. Faces that align more closely with the cultural average are easier for the brain to process and may have fewer unusual variations.
Symmetry and Uniqueness: A Complex Relationship
While symmetry was once seen as a sign of attractiveness, the study found that unique facial features also play a role. Faces that stood out from the average shape were rated as less attractive. This complicates our understanding of the relationship between symmetry and attractiveness, suggesting that a symmetrical face might be closer to the culturally expected average.
Conclusion
This study sheds light on the complexity of attractiveness, revealing that beauty is not as straightforward as once thought. Factors like cultural familiarity and uniqueness play a role in shaping perceptions. Ultimately, the concept of attractiveness can be relative and change across different cultures and societies, reflecting the complexity of human perception of beauty.
