For the study, published in the journal Proceedings of the Royal Society B, Jenkins and his team asked participants to write down as many faces they could remember from their personal lives. "We found that people know around 5,000 faces on average," Jenkins said. "Psychological research in humans has revealed important differences between unfamiliar and familiar face recognition," said Jenkins. While the team said it was focused on how many faces humans actually know, they said it might be possible for some people to continue learning to recognise an unlimited number of faces, given enough practice. Jenkins said it was not clear why we developed the ability to distinguish between thousands of faces in the crowd.
