感实性或译以为真实而非事实（Truthiness）是美国讽刺性喜剧演员史蒂芬·科拜尔（Stephen Colbert）所用的一个词汇。它首先被用于2005年10月17日《科拜尔报告》（The Colbert Report）的电视节目首集中。这一词是用来形容一种“感觉上是真实”的特质。相对于真实性，感实性与事实和逻辑无关。对一事物之感实性的唯一衡量是单以直觉来感受此事物有多正确或可信。

此词汇于2006年1月6日被美国方言学会选为2005年的年度字汇。在2006年12月10日，它也同样被《韦氏词典》选为其2006年的年度字汇，击败了同时角逐此头衔的字汇《谷歌》。

Truthiness is a quality characterizing a "truth" that a person making an argument or assertion claims to know intuitively "from the gut" or because it "feels right" without regard to evidence, logic, intellectual examination, or facts.

American television comedian Stephen Colbert coined the word in this meaning as the subject of a segment called "The Wørd" during the pilot episode of his political satire program The Colbert Report on October 17, 2005. By using this as part of his routine, Colbert satirized the misuse of appeal to emotion and "gut feeling" as a rhetorical device in contemporaneous 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, including Wikipedia. Colbert has sometimes used a Dog Latin version of the term, "Veritasiness". For example, in Colbert's "Operation Iraqi Stephen: Going Commando" the word "Veritasiness" can be seen on the banner above the eagle on the operation's seal.
