DEFENSE DEPTH AND STRUCTURAL COHERENCE
Metrics for Theory Evaluation in Complex Systems
Abstract: This paper proposes a formal framework for evaluating theoretical robustness beyond citation counts. We introduce two metrics: UTDGS (Universal Theory Defense Grading System) for measuring adversarial resilience, and Structural Coherence Invariants (SCI) for measuring systemic survivability. We argue that a theory’s epistemological value is defined by its ability to absorb error, bound its scope, and maintain internal consistency under stress.

1. THE MISSING METRIC: ADVERSARIAL RESILIENCE
Current academic metrics (H-Index, Impact Factor) measure diffusion (popularity), not durability (truth-survival). A robust theory must demonstrate “Defense Depth”—the capacity to sustain a claim against rigorous, steelmanned objections.
We propose the Defense Width Principle:
The width of the defense architecture must match the controversy level of the claim.
The UTDGS Score quantifies this by measuring:
- Objection Anticipation: Does the theory identify its own strongest critics?
- Response Strength: Are objections resolved or merely dismissed?
- Chain Completeness: Do logical dependencies terminate in axioms or infinite regress?
2. STRUCTURAL COHERENCE INVARIANTS (SCI)
We identify 12 structural properties required for any information system to resist entropy. Historically termed “virtues,” these are re-defined here as System Survival Constraints.
| Structural Invariant | System Function | Failure Mode |
|---|---|---|
| Error Absorption (Grace) | Capacity to recover from local faults without systemic collapse. | Brittle Failure |
| Non-Terminality (Hope) | Architecture allows for future state-space expansion; no dead ends. | Deadlock / Stagnation |
| Iterative Convergence (Patience) | Ability to refine accuracy over successive epochs. | Premature Optimization |
| Signal Fidelity (Faithfulness) | Maintenance of core axiomatic structure over time. | Drift / Corruption |
| Scope Bounding (Self-Control) | Explicit definition of what the theory cannot explain. | Unfalsifiability |
| Positive-Sum Dynamics (Love) | Integration with external systems creates value surplus. | Parasitic / Zero-Sum |
| Internal Consistency (Peace) | Absence of logical contradictions within the axiom set. | Self-Negation |
| Reality Alignment (Truth) | High correlation between predictive models and observational data. | Hallucination |
| Update Capacity (Humility) | Mechanism for revising priors based on new evidence. | Dogmatic Calcification |
| Generative Surplus (Goodness) | The system produces more order (negentropy) than it consumes. | Entropic Decay |
| Integration (Unity) | Coherence across sub-domains; absence of silos. | Fragmentation |
| Resonance (Joy) | Positive feedback loops that sustain investigator engagement. | Burnout / Apathy |
3. CONCLUSION
A theory that violates these invariants is Structurally Unstable.
- Low Scope Bounding leads to pseudo-science.
- Low Update Capacity leads to obsolescence.
- Low Internal Consistency leads to logical explosion.
We propose these metrics as a standard for evaluating the long-term viability of any theoretical framework.
