Wow, I just lost all respect for The Met

…which is a pity as the Metropolitan Police in London are apparently world leaders in the use of super-recognizers in law enforcement.

Another computer algorithm created to perform a face perception task that any person can do without even thinking

Wenz, John This Algorithm Guesses Your Biological Age Just by Scanning Your Face. Popular Mechanics. April 1st 2015.

“For example, if a person appears to be considerably older than they really are, a doctor might look for something to explain that, whether it’s a genetic disorder or a lifestyle issue.”

I do not doubt the link between appearance of facial aging and genetic syndromes or drug addiction as I personally know of some real-life examples of both, and I don’t doubt that a good doctor should look for this in facial appearance and make appropriate investigations, but I do question why any doctor with normal eyesight and face perception would need a computer to do this, and I also question whether under the current “5 minute medicine” model of general practice in Australia, most doctors would have the time or the inclination to enquire about apparent accelerated physical aging in a patient.

I know of quite a long list of things that might accelerate the appearance of aging in the face, including at least one genetic disorder (I know of one family but do not know exactly which disorder), a drug addict lifestyle, smoking (which apparently destroys some vitamin and thus exposes cells to extra stress), and poorly controlled diabetes. There are probably many more things that can have this effect. Ask your doctor.

 

In a perfect world every doctor would be a super-recognizer

In Western Australia a male infertility patient and his partner were given IVF, but it was later found that he had a genetic disorder that could have been passed on to the baby. I think if the doctor responsible for this omission had been a super-recognizer, it is possible that he or she might have spotted something in this patient’s face or appearance that would have given them the tip that a genetic anomaly might have been an issue. Perhaps one day a version of the Perth face-space project with adult’s faces might be developed to routinely and automatically screen or identify such patients.

Would super-recognition be relevant to performance as a radiologist?
