I don't know how wide spread it is, but all the Swifties I've seen lately have become experts in moving the goal posts. Before it was, "Taylor gets all the awards because she's amazing!You can't criticise her because she won like 10 grammies! " now I'm hearing, "Oh, she doesn't need awards to prove how good she is!"
Cognitive dissonance. Literal definition is making up whatever you have to to keep the beliefs you want to keep. It’s like playing Calvin Ball. (Cookie to whoever gets the reference.) Her biggest fans are experts at this, but no matter what lies they tell themselves, her tanking chart numbers prove her mega fan numbers aren’t that high, her regular fans don’t care enough to help artificially boost her numbers, and the public doesn’t like her new music. If the GP did, her last three singles would have hit #1, hell have even hit Top 10 in two of their cases, like so many from her last album. People are tired of her and her antics.
