Super-recognizers have an extraordinary ability to recognize faces – they can pick faces they’ve seen only briefly out of a crowd and can recognize childhood acquaintances they haven’t seen in decades. Dr. Josh Davis, a professor of applied psychology at the University of Greenwich, and super-recognizer Kelly Desborough, discuss the origins of this ability, why you can’t train yourself to be a super-recognizer, how super-recognizers compare with facial-recognition algorithms, and why security organizations are interested in working with super-recognizers.
