The impetus for this article came from seeing the following optical illusion on Facebook last month:
What do you think?
Are the blue bars all parallel, or are they zig-zag? Can you believe what you
see?
Victoria Skye’s Illusions
The above image was created in 2017 by Victoria Skye, who
introduces herself on one
website as “a children’s and family magician and balloon twister in Atlanta,
Georgia.”
Another
website says she is a “magical entertainer” and “illusion artist,” and it
gives a link to the image above, which is called the “Skye Blue Café Wall Illusion.”
That website also links to a YouTube
video, which explains that the blue bars in the image are really parallel.
So, what about it? Can we really believe what we see (or
what we think we see)?
Believing What
You See
As you know, Missouri has long been called the Show-me
State. The origin of that unofficial motto goes back at least to Willard
Vandiver, who served from 1897 to 1905 as a Missouri member of the U.S. House
of Representatives.
According to this
2021 article in the St. Louis Post-Dispatch, Vandiver declared in a
1899 speech about a questionable issue, “I'm from Missouri, and you have got to
show me.”
As one born and reared in Missouri, I have always taken some
pride in our state’s motto: it is a caution against gullibility and a call for
verifiability.
One troubling problem, though, is that we humans don’t
always see things correctly. Even what we think we see clearly can sometimes be
an illusion—as the above image of Victoria Skye clearly shows. And we can be
mistaken about important, real-life matters also.
Thus, a large majority of the voters in the Show-me State were
under the illusion that their preferred candidate for POTUS in 2016 was an admirable
man who would lead the U.S. in a positive way. But after four years they were still
unable to believe what they saw and voted for him again.
Seeing What you Believe
Some things have to be believed in
order to be seen. That was the title of#20, the seven-page chapter in my book Thirty
True Things Everyone Needs to Know Now (2018). (I wish you all had my book
and would (re)read that chapter, but you can read it online here.)
In that chapter, as in my July 10
blog post, I quote the fox in The Little Prince: “Anything essential is
invisible to the eyes.” What we know intuitively or, yes, by faith is necessary
for “seeing” things that are of the greatest importance to us. We “see” those
things because of what we believe.
But here, too, is a knotty problem: our
beliefs are not always correct. Just as we can be misled by what we see with our
physical eyes (come on, the blue bars in Virginia Skye’s image are clearly
zigzag!), we can also be misled by what we incorrectly believe.
To avoid duplicating what I wrote
for #20 in my book, here is an important matter not discussed there—and something
I need to know more about. There is often, we are told, a skewing or
misunderstanding of “reality” by something psychologists call cognitive bias.
I found this 2020 article about that matter instructive, although it did not say
enough about the central importance of beliefs/presuppositions. But it did refer
to “confirmation bias,” which is “favoring information that conforms to . . .
existing beliefs and discounting evidence that does not conform.”
Because we all tend to see what we
believe, we have to examine our beliefs regularly just as we have to be sure
what we see with our physical eyes is correct. (The blue bars still look zigzag
to me!).
To use the previous example, we
“libtards” who strongly disagree with the “Trumpists” must discuss or debate
not just what we see/hear but most of all what we each believe and why.
To acknowledge that we all see what
we do and evaluate what we see on the basis of our basic
beliefs/presuppositions is of the greatest importance.
