Documentaries aim to inform, educate, or entertain audiences using real footage of events or interviews to describe real situations. Bill Nichols analyzed documentaries and found they reveal contemporary issues and problems to bring attention to, operating where social issues are consciously addressed through factual arguments rather than private fantasies. Prospect theory also applies as documentaries encourage viewers to form their own perspectives on issues and make choices, influencing decisions. However, Steve Barnett argued documentaries have been "dumbed down" for television audiences focused more on ratings than serious, informative content.
