Evolutionary psychologists suggest that ancient ancestors who experienced pareidolia were more likely to survive as a result of a higher personal alert for danger- perceiving things that weren’t always there - preparing them for the times when the threat was real. Whilst babies who recognised faces in quotidien objects were more likely to be cared for and survive according to Carl Sagan who theorised that, “Those infants who a million years ago were unable to recognise a face smiled back less, were less likely to win the hearts of their parents, and less likely to prosper”, which allowed pareidolia to be passed on to current generations.
