"Propaganda" is information, especially of a biased or misleading nature, used to promote or publicise a particular political cause or point of view. Propaganda is often associated with the psychological mechanisms of influencing and altering the attitude of a population toward a specific cause, position or political agenda in an effort to form a consensus to a standard set of belief patterns.

​

Propaganda is information that is not impartial and is used primarily to influence an audience and further an agenda, often by presenting facts selectively (perhaps lying by omission) to encourage a particular synthesis, or using loaded messages to produce an emotional rather than a rational response to the information presented.

​

Today the term propaganda is associated with a manipulative and jingoistic approach, but propaganda historically was a neutral descriptive term.
