Are You Good At Remembering Faces? Scotland Yard Wants You

Since 2011, the London agency has employed a team of "super-recognizers" who have an exceptional memory for faces. Despite their success, legal experts say their use could raise questions about what's considered allowable testimony in court.

What's the Latest Development?

London's Scotland Yard can lay claim to a unique group of police officers, all of whom share the same ability: They never forget a face. Known as "super recognizers," they are able to identify individuals from surveillance photos and videos with surprising accuracy. Says unit creator Mick Neville: "When we have an image of an unidentified criminal, I know exactly who to ask instead of sending it out to everyone and getting a bunch of false leads." They have even helped prevent some crimes from taking place: During a major carnival, officers scanned surveillance videos and pointed out known criminals, after which police presence was increased as a preemptive measure.

What's the Big Idea?

Unlike with fingerprints and DNA, Scotland Yard had no system in place that allowed identification from images. Despite their success, the super recognizers are human and therefore imperfect, which concerns legal experts like London School of Economics professor Mike Redmayne: "Unless we subject them to (rigorous testing), then we are just taking their word on trust and we have no reason to do this." However, University of Greenwich psychologist Josh Davis is impressed by their abilities, and is in the process of examining the officers in hopes of developing a test the agency can use for new recruits.

The philosophy of tragedy & the tragedy of philosophy - with Simon Critchley

Tragedy in art, from Ancient Greece to Breaking Bad, resists all our efforts to tie reality up in a neat bow, to draw some edifying lesson from it. Instead it confronts us with our own limitations, leaving us scrabbling in the rubble of certainty to figure out what's next.

A bionic lens undergoing clinical trials could soon give you superhuman abilities

We're talking Ghost in the Shell type of stuff. 


Maybe you watched Ghost in the Shell and maybe afterwards you and your friend had a conversation about whether or not you would opt in for some bionic upgrades if that was possible - like a liver that could let you drink unlimitedly or an eye that could give you superhuman vision. And maybe you had differing opinions but you concluded that it's irrelevant because the time to make such choices is far in the future. Well, it turns out, it's two years away.
