Word of the Day: pareidolia

Pareidolia is something that’s very common. So common, in fact, that you’ve probably seen countless examples of it. You knew what it was even if you didn’t know what it was called. Pareidolia is a type of false perception that helps us make sense of the world. It happens when our brains organise the completely random patterns seen by our eyes into things we can identify. This is why and indeed, how we “see” dragons in clouds, a man’s face on the Moon, and why the random burn marks on a grilled-cheese sandwich or a tortilla seem to resemble the Virgin Mary.

This is not something over which we have any control. Our brains are wired for it. Personally, I think it’s kind of weird and wonderful that we “see” human faces and familiar forms everywhere, but I’m left guessing as to the biological or evolutionary purpose of this ability. I’d like to think that there’s a reason for it but maybe it’s just a fluke. Still, it does provide a lot of entertainment value, particularly when people associate the things they think they see with the religious or the sacred. And it happens all the time. Here is a page from teh intarwebz with tons of examples. Some of them are pretty convincing, but others are really stretching it.

Finally here’s a very old photograph with some of the best pareidolia I’ve ever seen. The image of a Jesus-like face can clearly be seen next to the figure of the man in the middle left of the photograph. Look again and you’ll see that it’s actually a little girl sitting in her father’s lap.

Neat, huh?
