ineffbilis

Ineffbilis is a term used in theoretical discussions of complex systems to describe a paradoxical property in which some inefficiencies persist within a system because they contribute to resilience or adaptability. The term is a neologism and is not standardized across disciplines; it appears mainly in speculative and methodological discussions about trade-offs between efficiency and robustness.

In usage, ineffbilis is described as arising from redundancy, modularity, delayed feedback, or deliberate slack that dampens shocks and prevents cascading failures. Common manifestations include inventory buffers in supply chains, extra validation steps in software development, or diversified supplier networks that reduce exposure to single-point failures.

There is no single accepted metric for ineffbilis. Researchers often discuss it in terms of the efficiency-resilience trade-off, using multi-objective optimization, resilience scores, or surrogate indicators such as slack, redundancy, or time-to-failure. Critics argue that calling such phenomena ineffbilis risks normative bias or conflating inefficiency with resilience, while supporters view it as a useful lens for designing robust systems.

In practice, ineffbilis is sometimes invoked in engineering, organizational design, and ecological economics to explain why suboptimal local choices can yield superior global outcomes under uncertainty. As a concept, it remains debated and is not universally adopted, described by some as a thought experiment or heuristic rather than a formal theory.
