A failing democracy looks less like a political debate and more like a 'cytokine storm' in a sick body.

The Takeaway
We treat politics as a battle of ideas, but this paper models it as a 'biological circuit.' Using cybernetics, the authors identify 'Authoritarian Analgesia'—where a regime stops feeling the 'pain' of public feedback—and 'Polarization as a Cytokine Storm,' where the system’s own defenses start attacking its healthy parts. This mathematical approach explains why democracies suddenly oscillate or why dictatorships collapse for no apparent reason. It means our political stability isn't just about 'values'; it's about the 'hard-wired' feedback loops that keep a system alive. Democracy is a physiological state, not just an idea.
From the abstract
This article develops a control-theoretic account of democratic stability grounded in Norbert Wiener's cybernetics and systems physiology. We model democracy as a delayed negative feedback architecture designed to maintain social homeostasis and formalize three analytically distinct pathological failure modes. <div> Pathology I (Phase Lag and Hunting) arises when total loop latency τ exceeds the critical threshold τ_c derived from the Routh-Hurwitz criterion for a second-order Padé-reduced syste
