When you look at a picture like this, what do you see?
Chances are you see a face.
You see eyes,
you see a mouth,
you see emotions,
even though these are just inanimate objects,
there's nothing there. But you've
heard this story before, the internet
loves pictures like these. They sell on
eBay for a lot of money,
and they make headlines all the time.
"They say it's the face of Jesus
etched by nature on a hillside look at
this." "I certainly feel blessed." "Jesus."
It's clearly the image of what we know to be Jesus,
and there must be a reason."
It's caused by this phenomenon called pareidolia,
which is Greek for "beyond the image." Way
back in the day it was considered a symptom
of psychosis
Leonardo da Vinci wrote about it in a
notebook as good inspiration for
painters, and psychologists started to use
it as a mental evaluation technique.
The idea behind it is that our brains
consume a lot of random information all
the time and they're constantly trying
to pinpoint patterns to make sense of
everything around us.
So when we look at something like concrete
floor, our brains pick up the stuff that
makes sense like a letter of
the alphabet or two eyes and nose. And
these are the things that we're most
comfortable with and
familiar with, so whether or not they're
actually there, they're what we tend to
perceive because they make sense to us.
In this one experiment from 2011, people
were shown faces hidden inside a noise
background
and they recognized them really well, over
90 percent of the time in each trial.
But when they were given noise-only
images without faces hidden in them,
participants kept seeing faces about
40 percent of the time,
even when there was nothing there. Now scientists believe that this response is
caused by a
specific part of the brain called the
Fusiform face area which is
specialized for facial recognition.
And it starts working really early in
humans. Studies have shown that babies who were
given drawings that look like this will
consistently gravitate towards the one
that's arranged to look like a human
head
by about 12 months old. "On the tortilla
takes on the appearance
on Jesus his head his facial hair
the whole thing." But here's where it gets
interesting.
In a 2013 study, researchers at the
University of Helsinki tested 47
people for pareidolia.
Some of them were religious or paranormal
believers, and some of them were not.
And they found that the believers were
consistently more prone to perceiving
faces in random patterns than the
skeptics were.
So really it's no surprise that so
many of these incidents involve seeing
a face of a religious figure in a
random pattern, and that's what makes
this so interesting.
Our constant search for meaning in
everything is actually hardwired in our brains.
And that's what makes us who we are.
