Here’s how many faces you actually remember (and it’s more than you think)

People can remember up to 10,000 faces, with the average person able to recall around 5,000, a new study has found.

How many people’s faces do you think you recognise – not just your friends, but famous people on TV, or even people in your local shops?

The answer is likely to be far higher than you imagine, after scientists put a number on how many faces the average person recognises.

It’s 5,000, according to researchers from the University of York.

Humans once lived in small groups of around 100 individuals, but the study suggests that our abilities are enough to cope with the thousands of faces we encounter in the modern world.

Dr Rob Jenkins, from the Department of Psychology at the University of York, said: “Our study focused on the number of faces people actually know- we haven’t yet found a limit on how many faces the brain can handle.

“The ability to distinguish different individuals is clearly important–it allows you to keep track of people’s behaviour over time, and to modify your own behaviour accordingly.’

Volunteers were asked to write down all the people whose faces they knew, including famous faces, people they went to school with, colleagues and family.

Researchers monitored how quickly the volunteers ‘slowed down’.

They were also shown thousands of photographs of famous people and asked which ones they recognised.

The participants knew between 1,000 and 10,000 faces.

Dr Jenkins said, ‘The range could be explained by some people having a natural aptitude for remembering faces. There are differences in how much attention people pay to faces, and how efficiently they process the information.

‘Alternatively, it could reflect different social environments-some participants may have grown up in more densely populated places with more social input.’
