To counter this, mainstream politicians need to find a language of rebuttal (being called “pro-truth” might be a start). Humility and the acknowledgment of past hubris would help. The truth has powerful forces on its side. Any politician who makes contradictory promises to different audiences will soon be exposed on Facebook or YouTube. If an official lies about attending a particular meeting or seeking a campaign donation, a trail of e-mails may catch him out.

Democracies have institutions to help, too. Independent legal systems have mechanisms to establish truth (indeed, Melania Trump has turned to the law to seek redress for lies about her past). So, in their way, do the independent bodies created to inform policy—especially those that draw on science.
If Mr Trump loses in November, post-truth will seem less menacing, though he has been too successful for it to go away. The deeper worry is for countries like Russia and Turkey, where autocrats use the techniques of post-truth to silence opponents. The people that are cast adrift on an ocean of lies, the people there will have nothing to cling to. For them the novelty of post-truth may lead back to old-fashioned oppression.
