Is there an expert who could explain what's novel here ?

The layman summary seems to imply specialists are surprised that people judge distance differently which seem crazy to me. I mean we have known for decades that vision is the result of a complex process involving different parts of the visual system and that people results on tasks involving mainly vision (and coordination admittedly) vary.

What's the surprising part here ?

Not only that, Kant himself structured the idea of the world outside our field of experience in a critique of pure reason. Since then the idea that our experience is a perfect one and that all our ideas come from our experience has been questioned.

This is why when the interviewed said "We assume our perception is a perfect reflection of the physical world around us" it was really strange for me. Only those unaware of hundreds of years of advance in philosophy assume that. And this highlights possibly a field that is very much lacking in science, the critique of thought itself.

The scientists are trying to determine why we judge distance differently, and found that each individual will consistently have problems with particular areas in their field of sight.

They think this is a result of various imperfections forming when your eyes connected to your brain.

> “We assume our perception is a perfect reflection of the physical world around us, but this study shows that each of us has a unique visual fingerprint,”

I don’t think anyone makes that assumption. I think most people know we don’t actually “see” the physical world, our eyes receive electrical signals from photons and our brain interprets those signals and for lack of a better word we hallucinate the physical world (in the form of the visual light spectrum).

By its very nature, from a common sense point of view photons don’t hit our eyes at the same time or the same angle; therefore, electric impulses will be different reflected Differently in our hallucinations. And even if 2 people had the same distance/angle, there are sometimes other issues differentiating our hallucinations, just one example being color blindness, where for various reasons one person hallucinates different colors than another based on the same electric impulses from photons. Even without color blindness this happens regularly (think of the blue/white dress vs black/gold viral photo a few years back)

I think many educated people cognitively "know" this, or at least have heard it from somewhere. But I also think that the majority of people, educated or not, don't feel this in their actual lived experience. Your brain does a good job of telling you that what you see is what is.

Anecdotally I've always perceived that dress as blue/brown from the very beginning and I can't "switch" my vision to perceive it otherwise. It's incomprehensible to me that someone can see it as blue/white or even worse as black/gold :)

Did they forget to say why in the article ? I couldn't find it.
