Media-code institutionalization requires public visibility of selective processes.

Evidence

More developed forms of the institutionalization of media-codes are conceivable only if the selective achievements of media-guided processes (if not the selection achievements of the code itself) are socially visible. In order to deduce that other people accept matters for code-specific reasons, one has to be able to know, or at least to suspect, that selections do actually take place. This applies above all to differentiated communication media which no longer represent simply a shared reality. — Niklas Luhmann, Trust and Power, 746
