So it's more like, citation required for any scientific evidence it does have unique aesthetic properties. At the end of the day, it's just a myth that keeps getting repeated, not much different from anything else in:
https://en.wikipedia.org/wiki/List_of_common_misconceptions
(Which also mentions the golden ratio in one of its bullet points.)
Neglecting that any three points make a triangle, so this is basically just saying "a frame with three things in it".
Three is also a sort of especially unspecial number. Zero things is sort of special in the sense that there’s no concentration of focus (shot of a landscape that just establishes the environment). If the focus is on one thing, then that’s really drawing a ton of attention to that thing (camera zooms in on the murder weapon and lingers). Two things can often be focused on the contrast between them (the villain towers over the hero). Three is the lowest number that doesn’t have a ton of baggage.
