Such a system would demonstrate that apparent stability can exist without feedback control.\n\n**F6 — Rival (strongest form).** Apparent stability is passive equilibrium, not active feedback. Many systems that look like homeostasis are simply buffers — large reservoirs that damp fluctuations without active regulation. The “feedback” description is a theoretical overlay; the actual mechanism is mass action, diffusion, or other passive processes. Feedback is a useful model, not always a real mechanism. (Criticism of strong Gaia: Doolittle 2019 Science 366:eaaw0410.)\n\n**F7 — Independence.** MODERATE — with flags. Wiener (mathematics/engineering, MIT), Cannon (physiology, Harvard), and Ashby (psychiatry, Burden Neurological Institute/Bristol) developed feedback concepts independently from different disciplinary starting points. BUT: Wiener and Ashby met at the Macy Conferences; Ashby’s Introduction to Cybernetics (1956) explicitly builds on Wiener’s framework. Cannon’s homeostasis (1926, 1932) predates and was independent of Wiener (1948). Independence: HIGH for Cannon; MODERATE for Wiener-Ashby due to Macy Conference connection.\n\n**F8 — Pattern type.** Biological / structural.\n\n**F9 — Maps.** A12 (self-reference), A3 (pattern-dynamics).\n\n---\n\n## Corpus map\n- Previous: [Convergence Encyclopedia: C06](/a/convergence-encyclopedia-c06)\n- Next: [Convergence Encyclopedia: C08](/a/convergence-encyclopedia-c08)\n- Encyclopedia start: [The Schema](/a/convergence-encyclopedia-schema)\n- Same node, other planes: [Catalogue node C07](/a/oip-c07-feedback-cybernetics) · [Catalogue hub](/a/oip-convergence-public-article)\n- Edges touching C07: [convergence edge 6](/a/oip-convergence-edge-6)\n- Kin corpora: [Total Structure](/a/oip-total-structure) · [Signature of the Grain](/a/oip-sog-preamble-axioms)","ranking":"safety-first (interaction_risk/limitations), then quote-gated effective_weight","claims":[],"sources":[],"anecdotal_sources":[],"scientific_sources":[],"user_reports":[],"related_articles":[],"question_graph":{"slug":"convergence-encyclopedia-c07","questions":[],"evidence":[],"edges":[],"counts":{"questions":0,"evidence":0,"edges":0}},"honesty":{"active_claims":0,"retracted_claims":0,"cut_claims":0,"challenges":0,"scrub_events":0,"note":"Retracted/cut claims stay on ledger but are excluded from ask unless ?include_inactive=1"},"counts":{"claims":0,"claims_total":0,"sources":0,"anecdotal":0,"scientific":0,"user_reports":0,"questions":0,"evidence_ingests":0}}
