Face-reading AI will detect your political beliefs and IQ

A Stanford University expert has claimed that computer programmes will soon be able to guess your political leaning and IQ based on photos of your face.

Dr Michal Kosinski went viral last week after publishing research suggesting artificial intelligence (AI) can tell whether someone is straight or gay based on photos.

Now the psychologist and data scientist has claimed that sexual orientation is one of many character traits the AI will be able to detect in the coming years.

HOW DOES IT WORK? 

AI-powered computer programmes can learn how to determine certain traits by being shown a number of faces in a process known as ‘training’.

The machine must be fed a number of faces along with those people’s known character traits of beliefs.

After processing thousands of images, the AI can guess someone’s traits based just on their facial features.

Stanford researcher Dr Michal Kosinki claims he is working on AI software that can identify political beliefs, with preliminary results proving positive.

He said this is possible because, as previous research has shown, political views appear to be heritable.

Political leanings may be linked to genetic or developmental factors, which could lead to detectable facial differences.

As well as political beliefs and IQ, Dr Kosinski told the Guardian that algorithms will one day pick out whether people are predisposed to criminal behaviour and whether they have specific personality traits.

He claimed faces can reveal a lot of personal and private information about a person.

‘The face is an observable proxy for a wide range of factors, like your life history, your development factors, whether you’re healthy,’ he said.

While the comments have sparked privacy concerns among some groups, Dr Kosinski claims they could be used for good.

‘The technologies sound very dangerous and scary on the surface, but if used properly or ethically, they can really improve our existence,’ he said.

Dr Kosinki’s ‘gaydar’ AI was trained using a small batch of photos from online dating photos.

After processing the images, the AI could determine someone’s sexual orientation with 91 per cent accuracy in men, and 83 per cent in women.

Critics slammed the software, saying it could be used by anti-LGBT governments to ‘out’ men and women currently in the closet.

CONCERNS ABOUT THE TECHNOLOGY 

Critics say that the software could be used to ‘out’ men and women currently in the closet. 

The software in the wrong hands could in theory be used to pick out people who would rather keep their choice of sexual partners. 

Google search results show that the term ‘is my husband gay?’ is more common than ‘is my husband having an affair’ or ‘is my husband depressed’. 

In a leading article, the Economist warns: ‘In countries where homosexuality is a crime, software which promises to infer sexuality from a face is an alarming prospect.’ 

Political leanings may be linked to genetic or developmental factors, which could lead to detectable facial differences.

Dr Kosinski said previous studies have found that conservative politicians tend to be more attractive than liberals.

This may be because good-looking people have more advantages and are able to get ahead in life easier.  

Facial recognition may also be used to detect IQ, Dr Kosinki said.

He said that schools could one day use facial scans to help them decide which prospective students to take in.

To train their computer as part of last week’s ‘gaydar’ study, Dr Kosinki and his Stanford colleagues downloaded 130,741 different images of 36,630 individual men’s faces, and 170,360 images of 38,593 women from a US dating website.

The users had all declared their sexuality on their profiles.

Removing images which were not clear enough, they were left with even numbers of 35,326 pictures of 14,776 people, gay and straight, male and female.

Digitally scanning contours of the face, cheekbones, nose and chin the computer made hosts of measurements of the ratios between the different facial features.

It then logged which ones were more likely to appear in gay people than straight people.

Once the patterns associated with homosexuality were learnt, the system was shown faces it had not been shown before.

The system was tested by showing it a picture of two men, one gay and one straight.

When shown five photos of each man, it correctly selected the man’s sexuality 91 per cent of the time.

The model performed worse with women, telling gay and straight apart with 71 per cent accuracy after looking at one photo, and 83 per cent accuracy after five.

In both cases the level of performance far outstripped human ability to make this distinction.

But, GLAAD, the world’s largest LGBTQ media advocacy organization, and the Human Rights Campaign, the US’s largest LGBTQ civil rights organization, hit back after the study was released.

A statement this week called on all media who covered the study to include the flaws in the methodology – including that it made inaccurate assumptions, left out non-white subjects, and was not peer reviewed. 

CAN AI JUDGE IF YOU HAVE THE FACE OF A CRIMINAL?

Last year, a controversial paper was released, which investigated whether a computer could detect if a human could be a criminal, by analysing their facial features.

The study involved 1,856 faces of Chinese men aged 18 to 55, which were ‘controlled’ to account for ‘race, gender, age and facial expressions.’

730 of the photos belonged to criminals – although the images were not mugshots.

Last year, a controversial paper was released which investigated whether a computer could detect if a human could be a criminal, by analysing their facial features. The results suggest that people with smaller mouths, curvier upper lips and closer-set eyes (pictured top), are more likely to be criminals

The images were fed into a machine learning algorithm, which used four different methods (classifiers) of analysing facial features, to infer criminality.

The researchers write: ‘All four classifiers perform consistently well and produce evidence for the validity of automated face-induced inference on criminality, despite the historical controversy surrounding the topic.

‘Also, we find some discriminating structural features for predicting criminality, such as lip curvature, eye inner corner distance, and the so-called nose-mouth angle.’
