This calculator is
designed for estimating the KL-divergence
(and hence useful information)
associated with an information source (like a radio station or a blog).
Note that it does not ask which side of any issue is being treated,
but only what range of interactions are being considered.
Hence one should only count time spent on coverage of a given level
that brings in new, relevant, truthful, and internally-balanced information.
Of course that is easier said than done.
The numbers here might also come in handy
even if you give benefit of the doubt as to information quality.
Do some subjects by their nature cut across layers of organization?
In the six shaded rows below the first, simply type in numbers (e.g. in units of time, percent effort, or dollars spent) that represent the focus of a given communications channel, and then hit the [Update Values] button above or below the table.
The columns refer to the spatial scope of relevant communications, which means not so much what they cover but for what interest group they are intended. For instance, news about a pot hole on a small street in a large town in a far away country may not be relevant to any of these interest groups, and hence should not be counted at all.
The rows, and the multiplicity values, refer to the extent to which communications attempt to be informed to issues on more than one scale of organization. Hence a news outlet that focuses only on politics and/or consensus at the national level may have a spatial scope restricted primarily to the national level, and (perhaps worse) an organization-layer multiplicity that is quite small. You can see this, for instance, by replacing the intial value of 5 with 500 in the National Scope column of the Hierarchy/Consensus row, and hitting [Update Values].
In the future, one also might want to examine the extent to which communications address issues important on short, intermediate, and long time scales. After all, the extent to which communications are informed in a balanced way to developments on multiple scales of time, space, and organization may turn out to be important in the days head.
