How might framing or priming affect the way a reader or viewer thinks about an issue?

Explanation:  Framing is a powerful weapon in emphasizing parts of an issue or a whole by directing attention to a particular segment of information or events or to a particular event and then placing them in a particular sphere of meaning. In this way, framing emphasizes certain information, values, although there is some other information and values, so that emphasized information is then considered and discussed. Simply the attention of the reader, the viewer is directed to the parts which have become more obvious by framing than other parts of the event. Thus, the perception of the observer can be directly affected, although the actual facts of the event have not been altered, no one can say that the facts of the event are untrue, only some parts are more emphasized and the attention of the observer is directed to them.

Priming is a kind of stimulation of the primary memory or stimulation of some preconception, the basic perception of the reader, the viewer. Simply, people are summoned to something that is fundamentally stored in memory, as a kind of settled opinion for a particular environment or culture, and on this basis a conclusion, opinion, or even judgement of the observer is built.
