## The Golden Ratio of Facial Proportionality and its Relation to Interpersonal Relationships Post #3

My project has finally been completed after way more than two weeks of work, but when you really get into a project it becomes so enjoyable that you like spending extra time on it. As you probably know by now, my project was on the golden ratio and how it applies to interpersonal relationships. Just for a quick recap, the golden ratio is a ratio found in nature that has been found to be aesthetically pleasing to humans. It is directly related to the Fibonacci sequence, a sequence studied by scores of mathematicians for centuries because of its prevalence in the world around us. I read other studies about how people choose friends based off of others having similar personalities to themselves, and how people with the golden ratio in their faces are perceived as more aesthetically pleasing. I decided to combine these two ideas together for my project and see if people who have more aesthetically pleasing faces are friends with those that have a similar aesthetically pleasing face.

Today I thought I would let everyone get a little peek into how exactly the facial proportionality works. There are a lot of different lengths on the human face that exhibit the golden ratio, but for the purposes of my project, I chose only 3 to explore further.

I’ve been collecting faces over the past few days, and what a task that is! I have pretty much been harassing people to send me pictures of their faces so I am able to have enough data to make this actually work. Looking at the faces so far, it is pretty interesting that a lot of girls in the same groups do, in fact, look similar. Of course, that is just to my untrained eye, but still. Pretty cool. While I continue to collect faces and start to take measurements soon, I’ll leave you with some more information about the Golden Ratio and a little bit about how my project works.

What if a mathematical ratio were to determine who your friends are? Studies have long shown that people choose to be friends with those who exhibit similar qualities to themselves. Recent studies go even further to say that gene similarity plays a large role in the people we choose to associate with. But what if the ratio we are instinctively attracted to that is seen in nature and in our own bodies is responsible for how we choose our friends? For hundreds of years, scientists have studied the cross-cultural perception of human beauty and have discovered that the most aesthetically pleasing faces across all cultures are those that display the golden ratio. The “golden ratio,” denoted by Φ, was first noted for its aesthetic appeal and presence in nature by Pythagoras and Aristotle. The golden ratio is directly related to the Fibonacci sequence, explaining its prevalence in nature. It is also seen in early art and architecture, implying that humans are instinctively attracted to the ratio. A human face that exhibits the golden ratio is considered to be aesthetically pleasing, regardless of the attractiveness of individual features. Not every person’s face exhibits the golden ratio, however. The further away a person’s facial proportions are from the golden ratio, the less attractive they are perceived to be. I want to explore the relationship between groups of friends and their facial ratios’ proximity to the golden ratio. If people do choose their friends by subconsciously identifying a similar ratio to their own in someone else’s face, it is possible that in the future we could predict whom we get along with without ever meeting the person. Because people choose friends who are similar to themselves, and, further, who are genetically similar, it would be interesting to see if groups of friends have facial ratios that resemble one another.
