Truthiness is the belief or assertion that a particular statement is true based on the intuition or perceptions of some individual or individuals, without regard to evidence, logic, intellectual examination, or facts.[1][2] Truthiness can range from ignorant assertions of falsehoods to deliberate duplicity or propaganda intended to sway opinions.[3][4]
The concept of truthiness has emerged as a major subject of discussion surrounding U.S. politics during the late 20th and early 21st centuries because of the perception among some observers of a rise in propaganda and a growing hostility toward factual reporting and fact-based discussion.[3]
