First what is Pareidolia? The strict definition from Wikipedia states:
Pareidolia (pron.: // parr-i-DOH-lee-ə) is a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant. Common examples include seeing images of animals or faces in clouds, the man in the moon or the Moon rabbit, and hearing hidden messages on records when played in reverse.
Simply it is your mind making faces or other familiar objects from an optical illusion. In the Bigfoot world the critics claim that a combination of shadows, leaves, sticks, and camera angle form faces and/or partial bodies that are claimed to be Bigfoot.
It is a major problem for Bigfoot researchers because the Bigfoot does not parade out in the open asking for its picture to be taken. They hide and peek from dense foliage or from behind trees only exposing their head and small parts of their torso. Most the time only peeking with one eye. When you add to that the fact that their skin is gray or black and that they are covered in black/brown hair they are very difficult to see. Unfortunately this always gives the critics their "excuse" or "plausible explanation"
The critics use the public's ignorance of what Paredolia really is and how the phenomenon occurs. In my videos when I claim there is a Bigfoot in the footage I make sure of several factors so I can rule out Paredolia.
1. Does the subject maintain its integrity as I move?
2. Does the subject itself move?
3. Does the subject have eyes that reflect light and/or blink?
4. Perform follow-up and return to the location looking for the object or groups of objects that could have formed the subject.
When you add other factors such as mouth movement, eyes blinking, or total head/shoulder movement then the Paredolia explanation is laughable. This is why in my footage I always point out and loop facial or body movements.
The final nail in the coffin for the Paredolia explanation is eye shine and the eyes in general. An optical illusion of a face formed by light, shadow, and camera angle cannot have eyes that reflect sun light, react to sunlight, or move. When I have footage of a Bigfoot hiding in dense foliage I always concentrate on the eyes. If you can see the detail of the eye, see it blink, and reflect sunlight then the subject is real. It is impossible for the Paredolia phenomenon to create eyes that move, blink, react to sunlight, and reflect sunlight.
So next time you read comments where the critics are throwing around the phrase "Paredolia" take a closer look at the footage. Put the footage to the test. You might be surprised what you find and realize how ignorant the critics are when it comes to Paredolia.
