Caused perhaps because of the excess of dopamine in brain. Dopamine triggers the excessive pattern matching. Human ability to listen meaningful messages in meaningless/random noise is also pareidolia.
Seeing man on the moon or seeing an image of Jesus where there is none are examples of PAREIDOLIA.
The question is:
When do you say that there is an image or a meaningful sound in so-called random patterns?
Is image not dependent on the viewer and sound not dependent on the listener?
What exactly is the criterion based on which you may say that an image, or a sound is really there? If it is solely based on the majority perceiving it to be so, then it seems, it is not a correct one.
Suppose I observe an image of Jesus carved in a wood, which I found in the street. You do not see any image of Jesus in that same wooden block. You call that it is pareidolia with me.
What exactly is the truth in this matter?
Is there an image?(Because I can show it to you by carving it)
There is no image?(Because you cannot see it until I show it to you)
or based on the perceiver, both of the propositions are equally valid?
Is definition of an object being really in existence: Its being perceived by majority or authority?
[That does not seem to be true with the history of Science at least!]
