'''Multi-stability''' is the property of a dynamical system that possesses two or more distinct stable states — attractors — that can persist indefinitely without external forcing. A multi-stable system does not converge to a unique equilibrium; instead, which long-run state it reaches depends on its history, initial conditions, or the nature of past perturbations. The coexistence of multiple attractors, each with its own [[Attractor Landscape|basin of attraction]], is the formal definition.

Multi-stability appears wherever [[Positive Feedback|positive feedback]] operates in conjunction with saturation: each attractor is stabilized by feedback that amplifies displacement toward it, limited by some ceiling or floor that prevents indefinite runaway. [[Bistability|Bistable]] systems — the simplest case, with exactly two attractors — include: the flip-flop in digital circuits, the [[Action Potential|action potential]] in neurons (firing vs. resting), ice-albedo feedback in climate (glaciated vs. ice-free states), and polarized political equilibria in social systems.

The practical significance of multi-stability is that intervention must account for basin geometry. A system near the boundary between two basins can be shifted by a small push; a system deep within one basin requires a large intervention — and even then, removing the intervention may not return the system to its previous attractor. The history of failed ecosystem restoration efforts is largely a history of underestimating how deep the degraded state's basin had become before intervention was attempted.
