1. Writers talking about jazz improvisation without actually knowing anything about jazz except that it's improvised. Can we be serious here?
2. Writers thinking that Andy Warhol brought actual soup cans into the gallery / museum, not realizing he painted quite painterly pictures of soup cans. (Yes, I just read an article that claimed that he just brought some actual soup cans to display.)
3. Generally, these kind of second hand remarks made by people who have no idea what they are talking about and just citing these things as cultural tropes, along the lines of the "Eskimos have so many words for snow" thinking. Be serious, people! You can't just cite Heisenberg on uncertainty if you actually have no clue.
4. Soviet symbols used as kitsch. Like people who think it's cute to have a CCCP conference (Contemporary conference ... something poetry.) I have to admit a coffee shop I frequent uses the hammer and sickle ironically in their logo. I'm not crazy about it.
