The fact is that these celebrities have a different face shape — it depends on how aggressive we look in the eyes of other people.
People with a wide, square face, such as those of Hollywood actors Margot Robbie and Zac Efron, seem more energetic, assertive and unfriendly to others than those with a more elongated, oval face, such as singer Rihanna and actor Ben Affleck . This conclusion was made by psychologists from the University of New South Wales (Australia).
The researchers selected more than 17 passport photographs of male and female faces. The age of these people ranged from 6 to 93 years. For each image, the researchers measured the facial width-to-height ratio (FWHR).
To calculate this indicator, you need to divide the horizontal distance between the most distant points of the face from each other by the vertical distance between the upper lip and upper eyelids. The higher the FWHR, the wider the face and the closer its shape to a square. And vice versa: low FWHR indicates an elongated, oval face shape.
As it turned out, FWHR changes over time — but depending on age and gender
Thus, at the age of 27 to 40 years, this figure is on average significantly higher for men than for women. However, after 40, this ratio begins to change, and by the age of 48 it becomes directly opposite — in older women, on average, the FWHR is already significantly higher than in their male peers.
At the second stage of the study, selected photographs were shown to 121 volunteers: they were asked to rate the degree of aggressiveness of the people depicted in the photo. It turned out that the higher the FWHR (that is, the squarer the face), the more aggressive the person around seems to be. This relationship is especially pronounced for men aged 27–33 and for women aged 34–61.
The researchers suggested that the young man’s square face may signal his physical strength and other traditionally masculine traits, including a propensity for aggressive behavior. As for women’s faces, which become more square with age, such a change in the shape of the face most often simply accompanies age-related transformations — primarily an increase in body mass index, scientists say.
