- “A structure containing a trigger that requires more energy than it releases for its own use will suffer a net reduction of potential energy” (As quoted by R.N. ADAMS, 1988, p.53).
J.G. MILLER gives the following interpretation to the principle: “Systems which maintain stability over long periods of time apparently tend to reduce the costs involved in the activation of … associated variables” (1978, p.35).
He also observes that ZIPF may thus “have identified a general principle of work done by organisms”, as his principle states “that systems use least costly adjustments first, and more costly ones later”. This has the general meaning “that systems conserve resources by maintaining their subsystem functions efficient and by keeping down costs”.
MILLER adds that at least in the economic sense “this is optimization of the organism's behavior” (1978, p.436). The principle also seems to be related to H. SELYE General Adaptation Syndrome, and his concept of stress.
However, according to ADAMS, the principle is somewhat of an obvious statement. Yet, its consequences can be obscured in biological organisms or social organizations in which, during a long time, some ill functioning parts are in condition to use resources obtained from other parts or subsystems. If such a squandering process is not reversed in due time the final breakdown becomes unavoidable.
