Ladies and Gentlemen, Mikhail Simkin's article on modern art makes entertaining reading, but the idea that such a quiz could provide serious evidence to answer the question "How good are modern artists?" with "The only difference between masterpieces and fakes is the heavyweight name attached to them" reveals a fundamental misconception of what modern art is about. This is a good example for how statistics can go wrong by ignoring the inherent ways of thinking of the subject matter to be analyzed. To begin with, here are some problems in the experimental design and its interpretation. 1. The quiz compares sometimes poor screen reproductions shrinked by a factor of several hundreds, I guess, from the canvas originals with fakes that have been created originally on the screen. So what's on offer here from the real artists is not what the artists meant it to be, while Simkin's fakes have been produced under the same conditions under which they are displayed. 2. Reasons for not recognizing "true art" could be different from what the author imagines. For example, how could a respondent, who doesn't know painting No. 4 but several other paintings of Malevich, be sure that the author didn't plagiarize Malevich's style skillfully to arrive at No. 4, even though it may as well be Malevich himself? Some respondents may have assumed (not too unreasonably) that Simkin did his best to lead them astray, and the best possibility to do that is to plagiarize well known artists while offering atypical originals. Therefore some artworks may have been nominated as fakes not despite but because they look "trueish" by some respondents. 3. The choice of original artworks has certainly not been done randomly. Obviously the author has chosen artworks on purpose that are minimalist in the sense that they don't clearly reveal much technical skill (at least not on the screen) and could intuitively be taken as produced by a child - or a statistician. This leads to the deeper problems with the author's reasoning. The author has asked to identify the original works, but it is not the main purpose of good art to be identified easily, and by a majority of people, in such a quiz. Why then should the quiz results tell us anything about the quality of the artworks? The appreciation of art is subjective, and a work that stimulates a deep esthetic experience among 5% of the participants while it's quality remains unnoticed by all others, could legitimately be considered as having the job of a masterpiece done properly under such difficult conditions. The data don't provide any evidence against the hypothesis that such a thing happened with the real masterpieces, so I don't see any relevant evidence against the artists here. Furthermore, the fact that most of the masterpieces selected here are deliberately minimalist points to another insight missing in the article. The discussion whether valuable art can be produced based on simple geometrical shapes or on a technical level that children could master is part of the background of modern art. At least some of the artists experimented very consciously with this idea, leading to some of the original artworks shown in the quiz, and the fact that the best part of an uninformed audience at first sight has difficulties to distinguish their works from fakes would rather come as a confirmation to them. These artworks are not only what Simkin showed; they played a significant role in a specific context which cannot be recognized in such a quiz. In fact, these works paved the way for what Simkin did when producing his fakes. Having done what Malevich did is much more of an achievement than producing something that looks like Malevich today. These artists have changed our perception. Instead of ridiculing the artists, Mikhail Simkin should be grateful, because they made possible what he has done. His own "works" owe quite a bit to Miro and Elsworth Kelly, and even though he doesn't consider himself as a talented artist, I'm sure he had at least some fun producing them. The fact that some of them are quite nice is rather testimony for the success of the original artists than proof of their failure. To come to the conclusion, the idea that quality in art could be modelled by an objective one-dimensional weight scale to be inferred from quiz results alone and a test whether "true art" can be distinguished from fake on this scale is a totally inappropriate conception of a statistician who seems to overestimate the power of his discipline in such circumstances hugely. (Note that Simkin doesn't even attempt to define what "true art" is.) Actually, the "creative" use of the concept of "artistic grams" and weightlifting categories to explain away the fact that despite all flaws more than 60% of the answers were correct even after taking into account possible knowledge of some of masterpieces to some of the respondents lets me wonder how serious Mr Simkin himself takes his claims.
