In short, QFT didn't get used for anything other than Quantum Field Theory prior to October 2005. It was only after October 2005 that QFT became popular. October 2005 just happens to coincide with the beginning of the use of the term truthiness.
- Because there seems to be confusion regarding whether one of the meanings of QFT is Quoted For Truthiness or Quoted For Truth, I did a little research. QFT was limited to quantum theory discussions prior to the beginning of the use of the word truthiness on October 17, 2005. You can see that clearly by the results returned on the Google usenet search I set up. Now, if you do the same search on the phrase quoted for truth and QFT during the same period, you get no results. The "reference" used to support Quoted For Truth is freedictionary.org, which only recently added it and provides no sources to back it up. One can easily conclude that QFT wouldn't be in use if not for the creation of the word truthiness and the popularity of the news satire program that used it w:The Colbert Report. It seems that people outside the loop misunderstood its use at some point and simply started making things up, including things like Quite Fucking True which is also not found in use prior to October 2007. QFT also did not appear with other acronym/abbreviation collections at any time prior to October 2007  --Halliburton Shill 16:18, 16 June 2008 (UTC)

- I'd say senses 5-8 need citations. Those I haven't heard so far. -- Liliana • 20:44, 9 February 2012 (UTC)
