No disagreement, though it depends on where somebody is starting from, and this thread has been assuming a starting point nobody stated.

Adding the clinical framing, because it changes how the question reads. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

Coming at LibrarianMeg’s question from a different direction. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

Correct me if the detail matters more than I have assumed.
