Key takeaways

Read in full (NOTE-730).

  • The dual-order account is too narrow. Malfunction there needs a regulated switch between regimes that a first-order trait fails to follow. So a stiffening artery at rest, or a stress response that never triggers, cannot malfunction.
  • Its two assumptions are false of physiology. First-order norms are not all-or-nothing (bradycardia, hypoxia), and regulation is mostly continuous modulation, not switching.
  • The normative field. The viability space has viable, precarious and terminal regions. The field is “the minimum constant parametric change, for each point of the precarious region, necessary to avoid the irreversible disintegration of the system”.
  • Three failures. Subfunction: right direction, too slow. Malfunction: wrong or no direction. Nonfunction: nothing done where something must be. Regulatory traits fall under the same standard.
  • Compensation costs viability, so it does not hide a dysfunction, and some illness is a shrinking of the viability space rather than a failure to contribute. Shown in a one-variable toy model; no field is computed for a real organism.

Why this is here

A11 asked what makes a trusted policy’s success good for the organization and not just good at keeping its own authority. That is CLAIM-277’s open edge and QUESTION-087. THEORY-217 records the account and answers the question in part. An authority structure is a regulation, and regulations can malfunction against the organization’s own field. A shrinking of the viability space is harm on this account, which is where protective lock-in (TERM-020) would register. But the standard is the whole’s viability. An authority that keeps the organization as viable as before is not dysfunctional, however it came to rule, and note 23 leaves open which norms prevail when a regulatory level becomes autonomous.

The filing said the work criticizes Mossio, Saborido and Moreno 2009 (LIT-570). It cites that paper as part of the standard approach, but the definitions it criticizes are quoted from Moreno and Mossio’s 2015 book (LIT-536, unavailable) and Saborido 2011. The filing’s “viability theory” is Ashby’s viability space with bifurcation analysis; Aubin is not cited.
