Authoritative Narration is where a Story's Narrator and Narration (if it exists) is taken as FACT/TRUTH by the Audience.
The story audience assumes that what they are told is true.
BioShock 1 and 2 had NO Narration - Nothing for which the Player can depend on being Truth ( as you would have in a narrated Book Story ). The views you saw in the game would require interpretation as to How, When and Why they were done, and by whom. 
You might hear Audio Diaries and Radio Messages and see Signs and Letters ( and what characters might say ), but the people who created those are only expressing things from Their Own Point of View, and can be lying or lack understanding or only making their own assumptions. There were plenty of Motives in Rapture for people to lie. Likewise plenty of deranged minds which might spew delusion and their own biases.
Example : In BioShock, there are Audio Diaries which present the recorded voice of characters saying things which can be mere OPINION, and not Factual. Such a recording can be utter delusion or even intentional lies. The only FACT is that it was recorded. With people being able to falsify their identity ( Ahem : Atlas ... and do 'voices' ), the implied recorder themself may be a falsehood ).

Note : A Narrator who is a character in the story MAY NOT BE making a factually truthful Narration ( ie- Things being from the character's point of view ).
