Pareidolia: Why we see faces in nature and unusual places

Some scientists say there's a reason why we enjoy searching for faces in the clouds.

Have you ever seen a face in a cloud? Or eyes in a tree trunk? If so, you are not alone and scientists actually have a term for this fascinating psychological phenomenon.

Researchers call it pareidolia, which is the false perception of seeing a non-existent face or pattern in everyday objects. Some evolutionary psychologists say that seeing human characteristics in non-living things was advantageous to our ancestors and helped them survive for a variety of reasons.

Carl Sagan, a scientist that was specialized in a wide variety of subjects, theorized that babies are more likely to be cared for and have a better chance of survival if they can recognize a face. Sagan reasoned that babies would be more likely to “win the hearts of their parents” and would be better cared for if they were able to smile back at the faces they see.

This phenomenon also could have protected ancestors from predators, according to Sagan. Thinking that there is a face in the distance would have helped humans brace for a potential predator, which would have improved their chance of surviving and protecting their offspring.

"A classic example is the Stone Age guy standing there, scratching his beard, wondering whether that rustling in the bushes really is a sabre-toothed tiger. You're much more likely to survive if you assume it's a sabre-toothed tiger and get the hell out of there - otherwise you may end up as lunch," explained Christopher French of the British Psychological Society in an interview with BBC.
