There's this thing called the Sapir-Whorf hypothesis, that says, well, it says a lot of things. The basic observation is that we generally think with words, and then the hypothesis proposes that the structure of our language reflects and limits the way we can think. Variations suggest that if there's no way to say a thing in a language, then you cannot think that thing, and so forth. Babel-17 postulates a language with no first person constructs, with interesting results for the way speakers of that language think and view the world.
There are aspects of this hypothesis that are obviously true, aspects that are almost certainly false, and a whole bunch of grey stuff in the middle. It's pretty hard to study, for obvious reasons.
Photography demonstrates pretty powerfully a variation on Sapir-Whorf.
If you don't know anything about photography, you're probably pretty OK at "grading" pictures, at least in terms of how powerful the picture is from the point of view of a layperson. After all, you're a layperson.
If you have a strong background in compositional theories and whatnot, you might be able to "grade" pictures pretty well, too, and you can, as a bonus, talk about why they're powerful or whatever.
If you have a weak and shoddy background, however, you suddenly lose the ability to grade things worth a damn. If is as if you've learned how to salt a soup properly, and now you judge soups entirely on whether they're properly salted. A soup made out of dogshit, properly salted, seems pretty good to you.
Go in any photography forum. You'll find people posting awful pictures, dogshit soup, which are in-focus, have some sort of correct white balance, and use the rule or thirds, or leading lines, or something. Then you'll find the community lining up to say how great the pictures are.
Having no vocabulary, they would be forced to simply report how they feel about a picture. With a rich vocabulary they could explain why, maybe. With the little bit of vocabulary most self-styled photographers have, Sapir-Whorf comes boiling out, and now, it seems, people have no other way to judge pictures. So they judge huge swathes of pictures as equally good. A crummy fashion photo that's in focus, and a superb one, are all "great shot!" because they have no vocabulary to describe the differences, and therefore literally cannot perceive them. The standards in play are simple, imbecile. The pictures are all over the place, but generally not very good.
It's an interesting phenomenon, which underlines why photographers are more or less the worst people to get any kind of critique from.
There's a further consequence. You, while obviously you are wise and good looking, are not immune. You probably can't see flaws you have no vocabulary for. If you strain, you might see that your picture is bad, but you may lack the words, the ideas, necessary to quantify why.
This is why being "self-taught" is bullshit. If you can't see what is wrong, you can't fix it. You can look at other people's pictures, and maybe mimic what they do, but unless you're naturally gifted you're just going to be doing a great job of salting soup made of dogshit. You might some day learn enough by mimicry to produce good pictures from time to time, or even pretty often. But you could just go do some learning.
