A friend recently sent me an issue of the Annals of Improbable Research that featured an instance of pareidolia on the back cover. Pareidolia, or the brain’s tendency to read patterns in random input – especially faces or human forms, has been a subject addressed on this blog before. Nevertheless, the phenomenon has continued to find wider exposure on the internet, and its implications continue to grow. The Cheezburger folks who brought us LOL Cats now have a site dedicated to pareidolia entitled “Happy Chair is Happy.” The question is not so much why we see faces everywhere, but what do we do about it.

Perhaps the most prevalent uses of pareidolia in natural phenomena (human-made objects are often funny or uncanny, but the faces may be there by intentional design) revolve around the supernatural. Would-be ghost hunters find what looks like a face in a window or shadowy corner and interpret it as a disembodied spirit. Religious believers of various faiths find the faces of their founders or leaders in natural noise. A tract I saw as a child told the heart-wrenching story of a woman who’d given up hope. She randomly took a photograph of her garden and when she developed it (this was back when film was actually still in use), she found the face of Jesus in among the leaves. Her angst alleviated, she went on to face life with a fresh sense of possibilities.

We often see what is not really there. On a visit to my niece last year, while waiting in the car outside her dorm, I saw a shadow on the wall that looked exactly like the recently deceased Michael Jackson. The shadow was cast by security lights through a bush, but the face was unmistakable. To test my observation, I asked my niece – who knew nothing of the fleeting rock star on the side of her building – if she could see it. Immediately it became obvious to her. An epiphany of Michael Jackson may be a religious event, or at least a supernatural one, to some. In reality it was a temporary arrangement of leaves aligned just right to catch a security light to form a public icon. Putting faith in pareidolia is a very haphazard source of security. However, if it helps someone deal with the stresses and strains of life, what harm is there in seeing Jesus (or Michael Jackson) where he really isn’t present?
