Epistemic Merit Model

The epistemic merit model is a method for understanding propaganda conceived by Sheryl Tuttle Ross and detailed in her 2002 article for the "Journal of Aesthetic Education" entitled "Understanding Propaganda: The Epistemic Merit Model and Its Application to Art".
Ross developed the Epistemic merit model due to concern about narrow, misleading definitions of propaganda. She contrasted her model with the ideas of Pope Gregory XV, the Institute for Propaganda Analysis, Alfred Lee, F.C. Bartlett, and Hans Speier. Insisting that each of their respective discussions of propaganda are too narrow, Ross proposed her own definition.
What is Propaganda?
To appropriately discuss propaganda, Ross claims that one must consider a threefold communication model: that of Sender-Message-Receiver. "That is... propaganda involve[s]... the one who is persuading (Sender) [who is] doing so intentionally, [the] target for such persuasion (Receiver) and [the] means of reaching that target (Message)."
According to Ross, there are four conditions for a message to be considered propaganda.
What it Means to be Epistemically Defective.
It is misleading to say, as some do, that propaganda is simply false, or that it is conditional to an intent to lie, since often the propagandist believes in what he/she is propagandizing. In other words, it is not necessarily a lie if the person who creates the propaganda is trying to persuade you of a view that they actually hold. "The aim of the propagandist is to create the semblance of credibility." This means that they appeal to an epistemology that is weak or defective.False statements, bad arguments, immoral commands as well as inapt metaphors (and other literary tropes) are the sorts of things that are epistemically defective... Not only does epistemic defectiveness more accurately describe how propaganda endeavors to function... since many messages are in forms such as commands that do not admit to truth-values, [but it] also accounts for the role context plays in the workings of propaganda.
Art as Propaganda.
Throughout history those who have wished to persuade have used art to get their message out. This can be accomplished by hiring artists for the express aim of propagandizing or by investing new meanings to a previously nonpolitical work. Therefore, Ross states, it is important to consider "the conditions of its making [and] the conditions of its use."
