Take it upon oneself, from an external position, to model out all identified cultural entities according to specified criteria, and then having discovered all knowledge relating to those cultural entities which enable to be informed about all specifications, reinforce the identity and perception related to the existing list of cultural criteria, in particular in manners highly amenable to dichotomous (or similarly well-defined) treatment.
For those lost souls whose modelled cultural identification displays shortcomings or confusion, it may be necessary for the government to step in to save culture, for example via psychological campaigns to enforce and/or pin down specific packages and/or (in rare allowable cases) relatively varied combinations of packages of cultural identifications and/or preferences. The preceding may not be required for those whose abberrant modelled identification is proven to be a flawed estimate, for example if good mental health is regularly proven through 9-5 economic activity and sufficiently mainstream media consumption.
The top threat to saving culture is thus a refusal of any individual to provide sufficient information to enable the documentation required. Such threats to culture must be assisted to overcome their shortcomings and/or confusion to the point that they can be reliably counted upon to demonstrate non-loss of culture at predictable times and places.
If implementing the above, society will benefit generally if the ability to regulate culture can serve for its protection. This will be all the more true if generally mathematical procedures are applied, as this will assist in implementation of politically unbiased cultural regulation.
Bonus edition: Regulating the above at the level of one’s own language (for example via a library of pre-approved thoughts operated via mandatorily-mutually-sanctioned and remotely-applied neurotechnolgy) will assure its vitality and integrity, in particular if regulated widely within acceptable margins of error and variation. In this case, governmental control over the specific neural activities of the population can be assured for good mental health and cultural protection purposes at the same time, as legitimized by the notional similarity to the production of dictionaries and their historically frequent use in educational, learning and other activities.
