Research and General Information

In this section, you can find information on what Super-Recognisers are along with the lines of research our team is involved in.

What are Super-Recognisers?

Super-recognisers are individuals who are exceptionally good at recognising faces.

 

The ability seems to be mainly face-specific in that with most super-recognisers, superior skills do not necessarily transfer to other visual (e.g. object recognition) or cognitive abilities (intelligence). Currently, there is no evidence that super-recognisers are qualitatively different from the general population – in other words, there is no indication that their brains are somehow wired differently. Instead, their abilities appear to be at the extreme top end of a large spectrum of individual differences in face recognition ability. Developmental prosopagnosics (individuals who struggle to even recognise close acquaintances) appear to inhabit the bottom end.

 

Like many human and physical characteristics, this ability range may be normally distributed (bell-shaped), and there is evidence suggesting that face recognition ability is inherited, although it is also dependent on experiential factors (e.g. exposure to different types of faces).

How common is Super-Recognition?

There is no standard definition or threshold above which someone is classified as a super-recogniser. Researchers have tended to use scores two standard deviations above a control mean on tests (suggesting 2% of the population may be super-recognisers).

 

In our research, we've found that only a minority of people who score in the top 2% range on the most common tests employed in research (e.g. Cambridge Face Memory Test: Extended: Russell et al., 2009) perform at that level on all tests suggesting that 'true' super-recognisers comprise a smaller proportion of the population. Because of this, when working with police or business we have often employed a large battery of tests. However, relatively poor performance on one test in a battery does not necessarily imply lower ability, as there may be a multitude of factors involved (fatigue, distractions, misunderstanding test requirements etc.), that are nothing to do with face recognition. Furthermore, in the ‘real world’ people use more cues to assess identity than faces alone (e.g., gait, full body, voice), and therefore tests will always only be a rough marker of ability. Indeed, it is unlikely any test or combination of tests, however, designed, will ever be able to perfectly predict super-recogniser performance in most workplaces. Day-to-day deployment and personal motivations will always influence the performance of even the most skilled individual in any job role. 

 

In addition, in some individuals there does seem to be a dissociation between face recognition ability and simultaneous face matching ability. Some people are exceptional at one but not the other – some are excellent at both. This supports theories suggesting that face perception and face memory are supported by different cognitive systems.

They are all conducted under the auspices of the University of Greenwich, with all research and enterprise projects approved by the University of Greenwich Research Ethics Committee (UREC).

More on Super-Recognisers

Here are some videos in which Josh Davis describes Super-Recognisers, their abilities and how they can be utilized.

Super-recognisers (The One Show, BBC 1 Scotland): Dr Josh P Davis (University of Greenwich)

Could you be a super-recogniser? Why not try our 5 minutes test to find out (link here): https://www.superrecognisers.com/take-part This is a video extract from the One Show (BBC1, 7PM), from 9th April 2013 It was filmed at the Old Naval College in Greenwich, the site of a University of Greenwich campus. The copyright of this video is owned by BBC Scotland. It was loaded on YouTube for educational purposes by Professor Josh P Davis in 2013 (University of Greenwich) who features prominently in the clip. Note – the information loaded on YouTube about this clip was updated on 9 June 2024, out of respect, after hearing about the death of the BBC’s interviewer, Michael Mosley. Information was somewhat limited, while URL links were out of date. Video footage The clip first features BBC interviewer, Michael Mosley speaking to PC Gary Collins (Metropolitan Police Service, MPS), a super-recogniser with exceptionally good face recognition ability, who from CCTV footage, identified about 180 suspects alleged to have been involved in the London Riots of August 2011. At the time, Gary was the most successful super-recogniser in the MPS (and almost certainly the world). In total, 600 rioters were identified by about 20 super-recognisers. Another 3,400 rioters, mostly one-offs were identified by police and members of the public. (Note that the super-recognisers had been making multiple identifications of suspects, before the riots.). These results contrast with the fact that only one suspect was identified by the best face recognition technology in the world at the time. Today's systems would perform more effectively, but given the placement of cameras on poles, the night time filming, the prevalence of smoke from fires, and the covering of rioter faces, super-recognisers would probably still outperform the technology. The technology works best with high-quality, close-up images taken with the target facing the camera. Dr Josh P Davis (University of Greenwich) was also interviewed by Michael Mosley, as at the time, he was researching the abilities of the super-recognisers in the MPS (Davis et al., 2016). For the research started in April 2011, a few months prior to the riots, police super-recognisers and controls completed a series of four face recognition tests. A high proportion of super-recognisers produced high scores on the tests, confirming their superior skills. Gary Collins was the highest overall scorer on the tests. Demonstration experiment - confused? This will help Much of the video is dedicated to a surprise (to Gary and Michael) "demonstration experiment" with the aim of demonstrating the skill levels of Gary Collins. Five people were asked to draw attention to themselves in a café, where Michael and Gary had a cup of coffee each. Once they left the café, and without being warned in advance about this, Gary and Michael were taken to view an identity parade containing ten people. Michael stated that he thought his own face recognition ability was quite good. It is perhaps not surprising therefore that Gary only outperformed Michael by 2 out of 7. Michaël Mosley = 4 out of 7 correct Gary Collins: 6 out of 7 correct Note, that a “Improving the Use of CCTV: Lessons learnt from the Riots 2011 Workshop was held at New Scotland Yard, London in September 2013. Josh Davis gave a presentation on “Super-Recognisers in the Metropolitan Police”. Mark Rowley (Assistant Commissioner), who in 2022 was appointed Commissioner of the Metropolitan Police, delivered the welcome speech. He mentioned super-recognisers and his hope that their benefits to policing would be fully investigated. A full-time super-recogniser unit was established in 2015. This unit provides a model of best practice that has been replicated by more than 40 police forces worldwide.

Research Areas

Face Recognition

Since the discovery of people with superior face recognition ability (Russell et al., 2009), interest in such individuals have grown exponentially from researchers, private organizations, police forces as well as governments.

 

Starting from 2011, Josh Davis and his team have been investigating this peculiar ability and have published abundant research dissecting the underlying mechanisms of superior face recognition. This research has resulted in consultancy for lots of organizations in terms of recruitment.
