I have read several claims in all kinds of literature (both scientific, less scientific and downwards anti-scientific) about golden ratio and its "aesthetics".
However, all the "proofs" I have seen seemed to me like arbitrarily chosen and ignored all kind of aesthetically pleasing ratios, like 1:2, 2:3 etc., that appear in various art, too.
So, my question is - was the claim that "golden ratio is the most aesthetically pleasing ratio" ever really proved?
(note: I have seen other claims about golden ratio, that seemed unfounded, but I will leave that for later. Right now I want to focus on the claim of aesthetics.)
