What the hell is this paragraph?

Perceived visual angle#Example: the Ebbinghaus illusion ``` The "paradox" completely vanishes, however, when the illusion is described, instead, as basically a visual angle illusion: That is, the perceived visual angle θ′ is larger for the lower circle than for the upper circle: It is as if its retinal image were larger. So. according to the "new" perceptual invariance hypothesis, (S′ / D′ = tan θ′), with θ′ larger for the lower circle, and with D′ correctly the same for both circles, then S′ becomes larger for the lower one by the same ratio that θ′ is larger. That is, the reason the lower one looks a larger linear size on the page is because it looks a larger angular size than the upper one. ```

It's like a blog post with someone giving their opinion. Maybe it's valid, and if it were written in a less convoluted and more comprehensible way I wouldn't mind it being included, but as it is, it stands out like a sore thumb in this article. ~2025-41601-45 (talk) 01:04, 19 December 2025 (UTC)[reply]
