I reject the post-truth naming. A world were lies are prevalent does not make truth not existent, only more important.
Where is the profitability of truth in politics? In government? In media? Truth has fallen by the wayside.
The courts only care about the law, not truth or justice. Those are literally words that came out of a sitting federal circuit court judge.
People are being shown every day that truth can be whatever you want it to be. Until there are actual consequences for telling lies, nothing will change, and truth will continue to be increasingly irrelevant.
