Are we living in a post-truth world?

Are we living in a post-truth world, where “alternative facts” replace actual facts and feelings have more weight than evidence? Is the the attack on truth and the media a step towards authoritarian rule? Lee McIntyre, author of Post-Truth, says this phenomenon has roots in the denial of scientific facts about smoking, evolution, vaccines and climate change, as well as fake news, among other things. He discusses the politicization of reality and how to combat post-truth.
