Which game do you want to win? It depends on the size of your chin! Scientists say that people who are more liberal in their views have smaller lower faces, while conservatives have squarer jaws

Some people famously wear their hearts on their sleeves. But is it possible to infer someone’s political preferences by looking at his or her face? Scientists say yes.

Researchers suggest that the size of your chin could predict how you will vote in the upcoming national elections.

They found that AI software could guess an individual’s political orientation with “significant accuracy” from just a photo of their face.

The technology was also able to accurately predict the political beliefs of 1,000 British politicians based on similar images.

Researchers from Stanford University in the US found that people who were more liberal in their views had smaller lower faces and chins. Those who tended to vote Conservative had larger lower faces and squarer jaws.

The photos of the 600 volunteers were “neutral,” meaning the individuals all wore black T-shirts, removed makeup or facial hair, and pinned their hair back, so the predictions could be made without any reference to personal style or other preferences that could have provided clues.

The predictions were accurate regardless of age, gender, race and location. “A single image of a neutral face reveals political orientation as accurately as job interviews reveal success at work or alcohol stimulates aggressiveness,” the researchers said.

They added that their results had “critical implications for privacy and the regulation of facial recognition technology” and urged policymakers to recognize the “potential risks.”

The study suggests that faces, and how they are perceived by others, can influence behavior and psychological traits.

The researchers describe it as a ‘self-fulfilling prophecy effect’ and suggest that people with larger jaws are often perceived as ‘more socially dominant, a trait associated with political conservatism’, and that over time this could lead to them actually becoming that way. way and to vote for the political right.

They also suggest that life experiences also have a subtle effect on the face.

“For example, liberals tend to smile more intensely and sincerely – which leaves traces in ripple patterns over time,” said the study, published in the journal American Psychologist.

‘Conservatives tend to have more self-discipline and are therefore healthier, consuming less alcohol and tobacco and having a better diet, which changes the fat distribution in the face and the health of their skin.’
