It’s a very well-known and basic concept in modern literary/art criticism.
The quizzes attack a straw-man conception of art nobody actually holds, which does not survive the slightest amount of scrutiny. They purport to show that there is no value to art, while only at best establishing that the value is not inherent; to you, the two seem to be the same, but nobody has seriously held the inherent value theory of art in a long time.
Again, why do you think a particular melody is beautiful? Is it an objective quality of the melody that makes it beautiful, or could somebody with a different cultural background or neural wiring perceive it as profoundly disharmonious? Is one set of tones just objectively better than another when played together?
People have televisions, computers, and all other sorts of things that are a direct result of a scientific practice that is just as easily ‘attacked’ by such quizzes and similar maneuvers as the modern art world is. The functioning of all these devices, of course, is proof that the practice works despite these attacks, which thus miss their mark, as they do regarding art. The average arXiv vs. snarXiv score is 57%, barely better than chance. But of course, this does not show that theoretical physics is a sham: it shows that the quiz has nothing to say about whether it is or isn’t.
Perhaps as a stark example to bring out the faulty logic regarding these things, consider that, due to some genetic quirk, 50% of all people like a certain food, while the other 50% abhor it. The 50% liking it will extoll its virtues, praise it to others, maybe wax rhapsodically about its qualities, etc. An online poll in the manner of those you keep flaunting will, of course, show that whether or not the food is judged good is a matter of chance. Your inference then is that those that like the food are mistaken, duped, have fallen for a sham: after all, people can’t really tell whether it’s good or not—they merely guess! And look, you’ve cleverly exposed the rampant fakery. The story can easily be amended to cover cases providing a better analogy—such as there being two foods which taste alike to one group, and not to the another; nevertheless, the test might indicate that you can’t distinguish better than chance between them—but I trust the moral is clear.
Another story of how far the whole ‘distinguishing fake from true’ misses the mark is provided by Marcel Duchamp’s Fountain. Provided with the original (or a replica, as it’s long lost), and an actual urinal, nobody could distinguish the two: they’re physically identical. And of course, that’s the point: a urinal isn’t art, not on its own. But imbued with the right context, i.e. signed, placed in a museum, rotated from its normal angle of display, thus making it unusable for its original purpose, it is, as it makes just the statement that art is not in the object (on one reading, at least). But asking people in a plumbing store to decide which of two urinals is art is simply absurd, and claiming that the people’s failure to correctly identify the ‘art’ one, regardless of whether they are plumbers or college professors, establishes that there’s thus nothing to art, shows either a deep confusion about the notion of art or a disingenuity in the argument.
But, as a final comment, there’s a lot of ways to approach modern art; even your categorical denial can be used to open up a fruitful way of engagement with it, turning your entirely negative sentiment into something constructive. For suppose there were no ‘true’ modern art; everything produced under that umbrella were, part and parcel, just the same crap. There’s no difference between Jackson Pollock and an ape, and your four year old could paint that, and a urinal is something you piss in no matter whether it’s in a museum or a public toilet. Then, you’d still have to explain: why is it that this particular creation became famous and well known, and not that other one?
You’ll probably want to answer that it’s random, that in the absence of any difference to distinguish between this and that, simply blind chance was at work, allowing this one to bubble up to the top, while that one sank. Somebody claimed this is good, and, due to their standing and reputation, the rest of the sheep blindly followed. And you could leave it at that.
But of course, that would be a rather dissatisfying answer. After all, there’s no real randomness on the level of society. Social processes are chaotic, but they are deterministic. At least on a statistical level, everything chosen by society is chosen for a reason, simply by virtue of the fact that it can’t be chosen without a reason. So, far from being random, the pattern of what bubbles to the top is actually a direct result of the state of society, and, in a sense, provides a mirror to it.
This is an effect that is made very effective use of in certain kinds of psychological therapy: free association is never free, rather, it provides a snapshot of subliminal influences the patient may not be aware of. Similarly, aleatoric forms of art, unless they rely on some truly random process, provide a snapshot of the mind of the artist: random words on a page, drawn by the poet from his mind without any conscious intent to produce something meaningful, nevertheless aren’t produced randomly; rather, there is a reason for every word that is chosen—otherwise, it could not have been chosen. Neural processes are deterministic, and thus, these apparently random words (or other creations) actually provide us with a pretty good snapshot of what goes on behind the scenes—one just needs to be able to interpret it.
Thus, you can look at modern art as something that tells us a lot about the state of society; far from being meaningless, then, it is is in this sense a distillate of what makes our society tick. A far more productive approach towards modern art, even if one, like you, believes in its worthlessness both inherently and in context, is then in using it as a tool for the analysis of society (of course, in the context of being such a tool, it would then be anything but worthless, but that’s a problem I’ll leave to you to sort out). So, your art pessimism needn’t be completely negative, but rather, can be turned into the kind of constructive criticism that is needed to make art come alive; it is only in the refusal of such engagement with it that it could be said to be ‘meaningless’ or ‘worthless’. Art comes alive with (constructively) critical engagement. So ultimately, it’s up to you.
