Post-truth is a relatively new term that has gained popularity in recent years. It refers to a situation in which emotions and personal beliefs are given greater importance than objective facts. In modern politics, post-truth has become a common tactic. However, there are several synonyms that describe this phenomenon. Words like disinformation, propaganda, falsehood, and fake news are just a few alternatives. Whereas all of these have distinct connotations, they are used interchangeably, each referring to the manipulation of information to further a particular agenda. Whatever word one chooses, it is increasingly apparent that a post-truth world is one in which the role of factual information in decision making is greatly diminished.
