If you forget nothing, then it’s difficult to live in the moment, as today is forever cluttered by an increasing number of yesterdays. People with such neurological quirks, rare though though are, actually exist. From “Superhumans,” Michael Banissy’s new Aeon article, a passage about “super-recognizers”:

“These are a rare group of individuals who excel in the ability to remember faces. First reported in 2009 by researchers at Harvard University and Dartmouth College, these are people who really never forget a face. They can recognise people whom they might have seen only a few times in their lives or, as Brad Duchaine, one of the Dartmouth College research team, puts it, ‘an extra they saw in a movie years before’.

Such people can identify casual staff that served them years earlier, a waitress at a motorway inn they passed through, a car-park attendant they once glimpsed, or a fellow department store shopper with whom they never interacted. The difficulties that this super-ability might cause in social settings are easy enough to imagine, and many super-recognisers will hide their memory of long-ago encounters to avoid discomfiting people who never even registered them.

Work is ongoing to determine just how common super-recognisers are, but there is some evidence to suggest that they can put their skills to good use. For example, the Metropolitan Police Service in London used super-recognisers in their ranks to help identify individual rioters during the 2011 riots across the capital.”
