Propaganda.
Information: In argumentative or persuasive types of essays, you want to convince the reader about something, and in some case, they are used to make you believe in something. Why? Either you have some objective or point of view that you want others to believe. That objective can be malicious or pure.
Propaganda is also the same. It can be positive and negative. However, it is mostly used in a negative connotation.
Anyway, the answer is: Propaganda!
