When an art form, academic field, or science becomes so advanced that you essentially have Deconstructions of Reconstructed topics, it becomes possible to fool experts with a sufficient grasp of jargon and absurdity. In other words, you can BS into seeming an expert while mocking True Art Is Incomprehensible. This is typically used to mock Post-Modernism or Dada (in as much as either can be mocked) and their proponents. Because when things become so abstract that true art/knowledge/expertise is almost indistinguishable from a random spouting of Technobabble, spray of color or screech of sound, it becomes easy to infiltrate and masquerade in those circles. With stuff like hard sciences and rigorous fields, posers are found fairly quickly, but a cunning knowledge of jargon terms and manipulating people makes discovery and exposure much harder. The flipside to this is that a person or work being completely honest, but failing at being good normal art, can get Mistaken for Exhibit or for avant gard in an unintentional form of So Bad, It's Good. Compare Mistaken for Badass. Film
- The documentary My Kid Could Paint That supposedly toys with this.
- In the movie Interstate 60, there is a Museum of Art Forgeries where in fact the art is the original and the forgeries are in the great museums. This may be some kind of further inversion of this trope.
- Catch Me If You Can has the protagonist successfully pose as a pilot this way.
- The film Bucket Full Of Blood had an unsuccessful sculptor accidentally kill and encase his cat in plaster. People assumed it and his following sculptures were authentic and not corpses, and he was hailed as a master for making something that could look "so alive and so dead".
- Referenced in Going Postal, as conman Moist is able to glean enough about a given field with some cursory research to sound like an expert to anyone who is not themself an expert.
- Inversion on The Commish. Tony finds abstract art incomprehensible, saying any idiot can paint like that. So he gets a challenge: paint an "abstract" painting; a group of art experts will look at it and a "real" abstract painting and determine which is the real one. He does so smugly, only to be shot down.
- xkcd Strip 451 is about a character pretending to be an expert in various fields and seeing how long it takes before he's found out. In most cases this is a matter of minutes, but for literary criticism he ends up writing multiple books and papers without anyone noticing.
- The Nostalgia Chick and Oancitizen's review of Freddy Got Fingered started out with the hypothesis that it might be trying for it, before concluding it's not trying to be so clever.
- There's an episode of The Simpsons where Homer becomes a famous artist but it might actually be an inversion of this: no one thinks he's particularly skilled, they like him within the category of outsider art. The joke is that a large number of outsider artists have very serious mental problems, implying that Homer has passed himself off as mentally ill.
- King of the Hill: Peggy's pipe sculptures were shown in an outsider art show. Another of the "artists" was simply a mentally-disturbed man who hoarded cans.
- The real life Sokal Affair, where physicist Alan Sokal submitted a paper of complete gibberish to the postmodernist journal Social Text and had it accepted.
- The "Rooter" incident, when Jeremy Stribling, Daniel Aguayo and Maxwell Krohn published a "scientific article" made of randomly generated words.
- The Disumbrationist School of Art, Art hoax of the 1920's.
