Second, there are diplomatic reasons behind the use of black propaganda. First, by using black propaganda a government is more likely to succeed in convincing their target audience that the information that they are seeking to influence them with is disguised and that its motivations are not apparent. Governments will generally conduct black propaganda operations for two different reasons. If the creators or senders of the black propaganda message do not adequately understand their intended audience, the message may be misunderstood, seem suspicious, or fail altogether.

Black propaganda relies on the willingness of the receiver to accept the credibility of the source. Black propaganda is the "big lie," including all types of creative deceit. Sometimes the source is concealed or credited to a false authority and spreads lies, fabrications, and deceptions. This type of propaganda is associated with covert psychological operations. Black propaganda purports to emanate from a source other than the true source. The major characteristic of black propaganda is that the people are not aware that someone is trying to influence them, and do not feel that they are being pushed in a certain direction.

Black propaganda is covert in nature in that its aims, identity, significance, and sources are hidden. Black propaganda contrasts with grey propaganda, the source of which is not identified, and white propaganda, in which the real source is declared and usually more accurate information is given, albeit slanted, distorted and omissive. It is typically used to vilify, embarrass or misrepresent the enemy. Black propaganda is false information and material that purports to be from a source on one side of a conflict, but is actually from the opposing side.
