I don t know and I don t see how that is relevant given that the inclusion rules clearly permit it Every biography is different but they are all built using the same basic set of rules no matter whether the person is a painter a politician or anyone else talking about their work and views If it informs the reader about the subject of the biography and the information has been selected by secondary RS it can in principal be included The relevance to the synth discussion is to show that that there is in my view a basic flaw an inconsistency in the argument If 10 things each individually qualify for inclusion then the notion that a single simple meta statement about them is synth and requires another source to demonstrate the importance of the 10 things is illogical Let me ask you this via a reductio ad absurdum The article includes the 2 books written by Levy If I were to add a statement that said Levy has written 2 books somewhere in the article would you argue that it is synth that I need a source that says Levy has written 2 books to avoid synth and to demonstrate that the easily verifiable fact that Levy has written 2 books is important enough to mention What if those 2 books were serialized and only published in the NYT Do the rules change if things are in the NYT
