Oxford University Press, that measurer of all things English, has told us we don’t have to believe it anymore.
Well, not really.
But it’s a fact that the editors there (including the editors of the renown OED, the arbiter of definitions and etymologies for the entire English speaking world) named the hyphenated word, “post-truth,” the word-of-the-year, though according to its very definition, we don’t have to believe it.
From the OED people:
Relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.
I can tell you that this does not fly in my journalism classes. We are college and will remain so for many, many, many more years than “post truth” can handle. The pendulum swings.
