According to aesthetic tastes, a study carried out in 2015 revealed that preferences for beauty are more closely linked to personal influences than to genetic factors.
This finding supports the well-known maxim “beauty is in the eye of the beholder,” suggesting that the assessment of beauty is ultimately a subjective perspective.

The research involved 35,000 volunteers, who were invited to evaluate the attractiveness of different faces through a website dedicated to studying brain functioning.
The results of this investigation were later shared in the scientific journal Current Biology. Check out the details of this research!
The psychologists responsible for the study, Jeremy Wilmer and Laura Germine, highlighted how one of the main conclusions the observation that there is general agreement that symmetrical faces are considered more attractive.
This characteristic, combined with other factors, contributed to a consensus of approximately 50% regarding the perception of beauty.
Wilmer explained that if a person were asked to evaluate the beauty of ten faces and then carried out the evaluation himself, there would be a 50% agreement in the results obtained.
In the second phase of the research, the facial preferences of 547 pairs of identical twins and 214 pairs of non-identical twins were examined.
The goal was to investigate how the effects of nature (genetics) and nurture (environment and shared experiences) play a role in the perception of beauty.
Comparison between identical twins, who share identical genes, has been highlighted as a comprehensive method and highly effective for evaluating the degree of heritability of characteristics, whether physical or psychological.
According to Germine, the environmental influences relevant to this characteristic are not those shared by two people who grew up in the same family.
Instead, they are subtle, personal factors, including unique characteristics, relationships with friends and colleagues, and the influences of social networks and the media.
These results suggest that the appreciation of beauty is a complex phenomenon, shaped by a combination of genetic and environmental elements, as well as characteristics unique to each individual.
