I went to an interesting seminar a few weeks ago. As part of it, the facilitator projected this image up on the screen.
They asked us to call out what we could see.
I could kinda, sorta, maybe see an alien face. Someone else called out “a field”. Another person shouted “a dog?”
“Yes!” said the facilitator, “a dog. Can anyone else see it?”
All of a sudden, the image snapped into focus for me. “Yes, a Dalmatian,” I said.
The person next shook their head, “isn’t it a eye staring upwards?
“No. You’re wrong.”
The person on the other side said “Is the dog sniffing the ground?”
“Well done! Said the facilitator, “that’s right.”
After a few moments, we were all convinced we could see a doggo having a rummage near a tree.
Then came the bombshell.
“There is no dog,” revealed the facilitator, “it’s just random dots!”
They’d deliberately only reacted positively to people who matched their preconceived notion. By excluding or ignoring people who dissented, it was easy to create groupthink. Praise and punishment are effective tools in shaping opinions on random data.
Let this be a lesson to you! Don’t just listen to people who agree with you.
But, something bugged me. I was sure I’d seen something similar before. After going down a few dead-ends, I found what I think is the original image in Life Magazine from 1965.
This is an actual photograph [emphasis added]. I’ll tell you what it is and then you might see it. It’s actually a Dalmatian dog, and a lot of it you can’t really see but once you realise or see it as a Dalmatian dog, then the rest of it kind of fits in and you can extract the dog from the pebbles on the beach. Perception is solving puzzles. Whenever we see any object, we have to separate it from the background. You have to see it as a thing in its own right. Here, because it’s difficult, you can see your own brain at work. There are all sorts of lessons about perceptions in this Dalmatian dog.
The major discovery in vision, is the image in the eye. The fact that you’ve got a little picture in the eye and that you’ve got the external world out there. You’ve then got the picture in the eye, then you’ve got the brain which tries to read what the reality is from the picture in the eye, and it’s important to note that you don’t see the picture. The picture is a stage, if you like, from the object to your brain, but you don’t have an eye looking at the picture in your eye. It simply is providing information to the brain but the really important point from all this is that the perception generated in your brain is very distinct from — it’s separate from — the world out there because of this image thing. Images between the object out there and your experience. Ditto with a television camera feeding into a computer. That separates the computer from the external world. The computer or the brain has to guess what is out there on the basis of information from the image, and it’s not direct.

Two ideas can simultaneously be true
Unconscious bias is real. It is devastatingly easy to hang around only with people who agree with you. We are all guilty of selectively filtering ideas to match our prejudices. It takes effort to break out of the traps our minds set.
But, sometimes, there is a dog in the photo.
