I’m curious if this relies on the fact that we’re looking at on pixelated screens to work. But not so curious that I’ll print it out to check.

As far as I know it relies on the fact that you only have clear vision in the central 20% of you FoV, and your brain just makes the rest up. Also the big blind spot

I thought it was 2°? A dime held out at arms length if I recall.

Honestly, idfk. Maybe that’s the blind spot?

Just now looking at things the clear bit of my FoV feels like 20%…which is clearly suuuper scientific. I’m getting ill, and have enough energy to comment on the internet or fact check myself…not both.

I’ve seen this illusion on paper and it still works. Not that printed paper is functionally different from pixels.

Ha, good point. I’m showing my age here. I understand our modern phone screens have resolution approaching that of good print, but when I think of a screen my brain still defaults to something like a 14" VGA at 57PPI :-)
