Hallin's spheres
Theory of media objectivity
Hallin's spheres is a theory of news reporting and its rhetorical framing posited by journalism historian Daniel C.
Hallin in his 1986 book The Uncensored War to explain the news coverage of the Vietnam War.[1] Hallin divides the world of political discourse into three concentric spheres: consensus, legitimate controversy, and deviance.
In the sphere of consensus, journalists assume everyone agrees. The sphere of legitimate controversy includes the standard political debates, and journalists are expected to remain neutral. The sphere of deviance falls outside the bounds of legitimate debate, and journalists can ignore it.
These boundaries shift, as public opinion shifts.[2] Hallin's spheres, which deals with the media, are similar to the Overton window, which deals with public opinion generally, and posits a sliding scale of public opinion on any given issue ranging from conventional wisdom to unacceptable.
