This question asks about an Einstein quote:
I know the origin of this quote is in a well referenced Feynman anecdote and sentiment, and I referenced the Feynman stuff. Further, I know the Einstein literature, and I said it doesn't appear there (although some similar sentiments do).
The question is answered, but I was told it was "unreferenced". I don't know how to reference a claim that someone didn't say something, other than by saying he didn't say it after a review, and letting someone with contrary evidence pipe up if they find the quote.
Is this answer really below the correct standard for a referenced answer? If not, can the "unreferenced" warning be removed? It contains references to all the Feynman material, some additional Schwinger/Feynman material, and Isaacson's biography, as a source for the similar sentiment Einstein makes for the EPR paper (I am pretty certain that this is where I read the EPR sentiment).
