Exhibit 1: When shown the picture below, adults tend to say that it is an erotic image, while children tend to see dolphins.




Exhibit 2: In the picture below, the two tables are the exact same size. I assure you. You can even measure it for yourself to make sure. Now, even if you do all that, do you see them as the same?




In exhibit 1, it seems that our model of the world heavily influences our perception. Yet in exhibit 2, no matter what we believe, our perception does not change.


Edit: Adding on, I wonder if you could train yourself to see those tables as the same? I wonder if a hypnotist could hypnotize someone to see those tables as the same? Wondering about the possibility, besides the fact that it might be useful for us to see them as different.
