Psychological Operations (PSYOP) are planned operations to convey selected information and indicators to audiences to influence their emotions, motives, and objective reasoning, and ultimately the behavior of governments, organizations, groups, and individuals. The purpose of United States psychological operations is to induce or reinforce behavior favorable to U.S. objectives. PSYOP involves the careful creation and dissemination of a product message. There are three types of products that are used to create these messages. They include White products which are used in overt operations and Gray and Black products which are used in covert PSYOP. White, Gray, and Black don't refer to the product's content but rather the methods used to carry out the operation. Think of White Hats, Black Hats and Grey Hats in the technology sector. 
Psychological warfare (PSYWAR), or the basic aspects of modern psychological operations (PSYOP), have been known by many other names or terms, including MISO, Psy Ops, Political Warfare, "Hearts and Minds," and propaganda. The term is used "to denote any action which is practiced mainly by psychological methods with the aim of evoking a planned psychological reaction in other people." Various techniques are used, and are aimed at influencing a target audience's value system, belief system, emotions, motives, reasoning, or behavior. It is used to induce confessions or reinforce attitudes and behaviors favorable to the originator's objectives, and are sometimes combined with black operations or false flag tactics. It is also used to destroy the morale of enemies through tactics that aim to depress troops' psychological states.Target audiences can be governments, organizations, groups, and individuals, and is not just limited to soldiers. Civilians of foreign territories can also be targeted by technology and media so as to cause an effect in the government of their country. 
Propaganda is "information, especially of a biased or misleading nature, used to promote a 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 objective 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 perception, or using loaded messages or "loaded language" to produce an emotional rather than a rational response to the information that is presented. Propaganda is often associated with material prepared by governments, but activist groups and companies can also produce propaganda. In the 2010s, the term propaganda is associated with a manipulative approach, but propaganda historically was a neutral descriptive term. A wide range of materials and media are used for conveying propaganda messages, which changed as new technologies were invented, including paintings, cartoons, posters, pamphlets, films, radio shows, TV shows, and websites.
