News that I didn’t have time to write about in November last year. The federal government of Australia plans to create a database of photo-id images. I’m not sure if this is just the National Facial Biometric Matching Capability renamed.
“A Face Identification Service (FIS) is expected to commence in 2017 to help determine the identity of unknown persons. It will be used for investigations of serious offences by specialist officers.”
Couldn’t be less detail or description or explanation in this statement.

Is there really a criminal face? I don’t think the research discussed in the New Scientist article settles the debate by any means, but at least the controversial idea is opened up for investigation. If there is one my guess is that it is a look that coincides with the Australian face (every race and nation has a distinctive averaged facial type, apparently). European colonisation of Australia began as a penal colony and thus a good part of the white genetics of Australians arrived in this country through people identified as criminals. My best guess is that the crim face has a large straight nose, thin lips and puffy, small eyes. I’d guess this unattractive face could in itself be a social and economic disadvantage, or could be symptomatic of a phenotype that includes some degree of intellectual impairment. I think if there is a crim face it might have little to do with personality but a lot to do with disadvantage, but this is all speculation.
I think it is worth noting that claims made in the print version of this article about supposed advantages of AI over humans in face recognition skills such as identifying age, gender, ethnicity and tiredness by looking at faces presumably only apply to humans of average face recognition ability who maybe are not as exhaustively trained in these skills as the AI systems have been. One cannot compare human ability with AI in face recognition until appropriately trained super-recognizers (representing the top end of human ability) have been pitted against machines. I’m guessing this hasn’t been done.
Perhaps the most important part of this article is right at the end; “…the majority of US police departments using face recognition do little to ensure that the software is accurate.” That certainly is not good enough. Human super-recognizers have abilities that have been proven in scientific testing and also in practice in policing in the UK. Why do so many people persist in the assumption that machines must be better than humans in visual processing, in the face of an abundance of evidence? The link in the New Scientist article to the website of the researchers who have criticized the use of face recognition technology in law enforcement in the United States of America is worth a look for sure.

Had you assumed that hiring human super-recognizers to perform face recognition tasks would be less effective, less accurate and more open to bias than using technology? Think again.

I was glad to read in this substantial and interesting article that face identification was not the only evidence used to convict criminals. And the last couple of sentences in this piece are too true!
Montagne, Renee ‘New Yorker’: The Detectives Who Never Forget A Face. NPR. August 17th 2016.
The See No Evil TV series episiode 3 about the murder of Kelsey Smith, which was broadcast on the Sunday just past on the Nine TV network in Australia was an illustrative example of the central and essential importance of crowdsourced face recognition and CCTV surveillance in solving serious crimes. I just wish that law-enforcement authorities wouold do more to use these tools to prevent crimes or to intervene in crimes, rather than waiting for someone to be killed or harmed, then using these tools to solve crimes.

And all bar one are open access! Please readers let me know if there are more studies on supers out there.

The above paper interesting as it apparently supports the idea that developmental prosopagnosia is a heterogeneous condition and at least the most severe cases are not simply the bottom end of a spectrum of ability. The authors do seem to regard supers as the top end of a spectrum though. Researchers also found that supers and able controls spent more time looking at noses, a finding which I think I recall from another study. It makes sense to me as I feel that great face recognition ability is an automatic and involuntary process (like synaesthesia) that involves perception of the face as a whole “landscape”.

Colour-blindness a variation in visual perception ability possibly endowing advantages relevant to work performance, rather than simply a disability
Payne, Rob Colour-blindness may aid in search and rescue effort. Science Network. November 11th 2015.
The idea that colour-blindness can be advantagous is not new to me, as last year I watched with great interest a story on ABC24’s News Breakfast in which the colour-blind presenter Michael Rowland explained his advantage over people with normal colour vision in visually detecting camouflaged items. Unfortunately the clip of this story is no longer available to view.
