Security concern is proportional to the relevance of the story for the individual, his or her family, social group and societal group, in declining order. At some point there is a Boundary of Relevance, beyond which the change is no longer perceived to be relevant, or newsworthy. This boundary may be manipulated by journalists, power elites and communicators seeking to encourage audiences to exclude, or embrace, certain groups: for instance, to distance a home audience from the enemy in time of war, or conversely, to highlight the plight of a distant culture so as to encourage support for aid programs.
