A New Difficulty in Achieving National Cohesion. A stable national government requires a measure of cohesion of the ruled. Such cohesion can be derived from an implicit mutual agreement on goals and direction — or even on the processes of determining goals and direction. With the diversity of information channels available, there is a growing ease of creating groups having access to distinctly differing models of reality, without overlap. For example, nearly every ideological group, from the student underground to the John Birchers, now has its own newspapers. Imagine a world in which there is a sufficient number of TV channels to keep each group, and in particular the less literate and tolerant members of the groups, wholly occupied? Will members of such groups ever again be able to talk meaningfully to one another? Will they ever obtain at least some information through the same filters so that their images of reality will overlap to some degree? Are we in danger of creating by electrical communications such diversity within society as to remove the commonness of experience necessary for human communication, political stability, and, indeed, nationhood itself? Must “confrontation” increasingly be used for human communication?
National political diversity requires good will and intelligence to work comfortably. The new visual media are not an unmixed blessing. This new diversity causes one to hope that the good will and intelligence of the nation is sufficiently broad-based to allow it to withstand the increasing communication pressures of the future.
