Admissible Indicator

Canonical definition

An Admissible Indicator is an Indicator by which a governing body may be assessed because the Indicator satisfies four conditions. Reach: the measured quantity lies within the causal reach of the body assessed, so that a change in the body's conduct produces a change in the Indicator. Exogeneity: the Indicator is obtainable without the audited body producing it, across the whole production chain rather than the final number alone, so its provenance must be reconstructible. Loop Safety: the path by which the Indicator is improved raises none of the couplings in the loop gain, which is a finite check because the host couplings form a closed set. Bounded Decoherence Time: the Indicator has a live Referent capable of contradicting it within a useful interval. The last two conditions interact, so that high Coupling Strength together with long Decoherence Time excludes an Indicator that is tolerable on each axis separately.
