Propaganda has sometimes been classified as "white," "black" or "gray." White propaganda generally comes from an openly identified source and is not intentionally deceptive. Black propaganda pretends to be from a friendly source, but is actually from an adversary and is intended to deceive its audience. Gray propaganda falls somewhere between white and black. Q. Why are most of the political ads 'black'? A. Because they work. Q. Why? A. Simple. Most Americans are too disinterested, or incapable of engaging in critical thought.
