From Wikipedia, the free encyclopedia
Post-truth politics (also called post-factual politics) is a political culture in which debate is framed largely by appeals to emotion disconnected from the details of policy, and by the repeated assertion of talking points to which factual rebuttals are ignored. Post-truth differs from traditional contesting and falsifying of truth by rendering it of “secondary” importance. The contemporary origin of the term is attributed to blogger David Roberts who used the term in 2010 in a column for Grist. It became widespread during the 2016 presidential election in the United States and the 2016 referendum on membership in the European Union in the United Kingdom. Political commentators have identified post-truth politics as ascendant in American, Australian, British and Indian politics, as well as in other areas of debate, driven by a combination of the 24-hour news cycle, false balance in news reporting, and the increasing ubiquity of social media.
