Post-Truth
by Lee McIntyre
How we arrived in a post-truth era, when “alternative facts” replace actual facts, and feelings have more weight than evidence.

What, exactly, is post-truth? Is it wishful thinking, political spin, mass delusion, bold-faced lying? McIntyre analyzes recent examples – claims about inauguration crowd size, crime statistics, and the popular vote – and finds that post-truth is an assertion of ideological supremacy by which its practitioners try to compel someone to believe something regardless of the evidence. Yet post-truth didn’t begin with the 2016 election; the denial of scientific facts about smoking, evolution, vaccines, and climate change offers a road map for more widespread fact denial. Add to this the wired-in cognitive biases that make us feel that our conclusions are based on good reasoning even when they are not, the decline of traditional media and the rise of social media, and the emergence of fake news as a political tool, and we have the ideal conditions for post-truth. McIntyre also argues provocatively that the right wing borrowed from postmodernism – specifically, the idea that there is no such thing as objective truth – in its attacks on science and facts.
McIntyre argues that we can fight post-truth, and that the first step in fighting post-truth is to understand it.
Review
“This is a gem of a short treatise. Lee McIntyre’s Post-Truth is a perfect counter to a problem that has erupted in our national consciousness – alternative facts. McIntyre’s enumerated suggestions on how we must all be our own fact checkers in this post-truth age should be taped to the computer keyboard of every journalist, politician, and reader in America, before the next election.” Michael Shermer, Skeptic Magazine
Review
“My book of the week is Post-Truth by Lee McIntyre. This is a slender volume from MIT’s Essential Knowledge Series that looks at one of the most disturbing trends of our time: the increasing dismissal of science, evidence, facts, and truth itself. The author gives us an intelligent account of why it’s happened and a compelling reminder that we should all fight back against this dangerous nihilistic idea.” Fareed Zakaria, CNN
