I think this whole discussion revolves on our interpretation of "pedantic".
"Excessive attention to detail" strikes me as something which can lead to loss of situational awareness i.e. concentrating on perfecting individual items to the detriment of the overall picture. I believe the majority of posters on this thread are conscientious highly professional individuals who are in the practice of double checking everything they do. I do not call that pedantry.
I personally think a pedant is the kind of person who refuses to select "Flap" 5, because the old flap lever is actually marked "flaps". Or the Captain who picks up an F/O because he has used calm wind to calculate performance, when the ATIS is giving a 10 kt headwind, when in reality the Capt is not using airmanship to cover the lulls, but after all is following the book.
