First names are social tags that are attached to us early in life. Previous studies have shown that an individual's facial appearance is indicative of their name. A new study explores the origins of this face-name matching effect – whether names are given based on innate facial features or whether an individual's facial appearance changes to match their name over time. Findings using both humans and machine learning algorithms show that while adults show a match between facial appearance and name, this pattern is not seen in children or in children's faces digitally aged to an adult appearance.

“George Orwell famously said, 'By the time you're 50, everyone has a suitable face,'” said Reichman University researcher Yonat Zwebner and his colleagues.
“Research supports Orwell's observations and suggests that changes in facial appearance over the years may be influenced by a person's personality and behaviour.”
“Our current study aims to explicitly test developmental aspects of facial appearance by focusing on social processes by taking advantage of a recently identified effect, the face-name congruency effect. The face-name congruency effect suggests that names can be manifested in the appearance of a face.”
In the study, the authors asked 9- to 10-year-old children and adults to match people's faces with names.
The findings revealed that both children and adults correctly matched adult faces to their corresponding names at rates well above chance.
However, when it came to children's faces and names, participants were unable to make accurate associations.
In another part of the study, a large database of images of human faces was fed into the machine learning system.
The computer recognized that facial representations of adults with the same name were significantly more similar to each other than to facial representations of adults with different names.
Conversely, no significant similarities were found when comparing children with the same name to children with different names.
The researchers concluded that the similarities between people's faces and names are the result of a self-fulfilling prophecy.
Facial appearance changes over time to conform to the social stereotypes associated with names.
These stereotypes can form in a variety of ways, such as when a name is associated with a famous person or because of the connotations that biblical names have.
“Our study highlights the broader importance of this surprising effect – the profound influence of social expectations,” Dr Zwebner said.
“We have demonstrated that social construction, or structuring, does in fact exist, something that has been almost impossible to verify empirically until now.”
“Social constructs are so powerful that they can affect how people look.”
“These findings may suggest the extent to which other personal factors, such as gender and ethnicity, that may be even more important than a name, may shape a person's personality as they grow up.”
