It’s not just one person’s brain, right? Everyone who was there would see the same thing. Surely, that means our brains are pretty much wired the same. But I wonder if some people would see the “correct” thing.

What’s also mind blowing is that the camera captures the same thing your brain is interpreting!

This is proven to be a physical illusion because the light sensor (camera) is capturing the same image as the two light sensors in your head (eyes). So no person would see the "correct" thing because the light in the scene is actually rendering this image with minimal interpretive transformations from the mind (this is in contrast to cognitive illusions). Unless there is a person with some extreme sensitivity to the polarization or color of the reflected light but that is probably unlikely.

I don't have the reference handy but I recall reading years ago that certain classic optical illusions simply don't work on people who weren't raised in societies with rectangular housing.
