Truthiness is a word that U.S. television comedian Stephen Colbert popularized in 2005 as a satirical term to describe things that a person claims to know intuitively or "from the gut" without regard to evidence, logic, intellectual examination, or facts. Colbert popularized this definition of the word during the inaugural (pilot) episode (October 17 2005) of his satirical television program The Colbert Report, as the subject of a segment called "The Wørd". It was named Word of the Year for 2005 by the American Dialect Society and for 2006 by Merriam-Webster.
By using the term as part of his routine, Colbert sought to satirize the use of appeal to emotion and the "gut feeling" as a rhetorical device in contemporary socio-political discourse. He particularly applied it to U.S. President George W. Bush's nomination of Harriet Miers to the Supreme Court and the decision to invade Iraq in 2003. Colbert later ascribed truthiness to other institutions and organizations, such as Wikipedia. video=72347" target="_blank">The Colbert Report / Comedy Central recording of The WØRD "Wikiality", _Comedy Central, July 31 2006.
