Shifting about in these language games, journalists have kept objectivity more or less the same over the years: a system of signs meant to persuade us to accept an account of what happened because it appears to contain only what happened and not what the composer of the account feels about it. That’s why you should trust it: because it appears unadorned. The way we capture this in popular culture is by reference to Joe Friday: “Just the facts, Ma’am.”
That’s not to say that an account presented this way actually is pure fact. No way. There is no act of journalism that is not saturated with judgment. Even a photograph is framed by the picture taker. When I refer to “Just the facts” I simply mean: that is how the story asks to be understood, not… “that is all there is to it.” There is always more to it.
So objectivity is persuasion, the method is “just the facts, lose the adjectives,” and the outcome is supposed to be the user’s trust. Got it?
