Risk, Fragility & Layered Defense

Primes about exposure to loss and the structures that contain or transmit it: layered protection (defense in depth, Swiss cheese model), fragility versus antifragility, concentration of dependency and vulnerability, and mechanisms for pooling, transferring, or absorbing systemic risk.

16 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its short description.

  • Antifragility — A system that gains capability from stressors and volatility, not merely withstands them.
  • Caldera Collapse — A structure fails not from load or rot but because its support was quietly evacuated from beneath.
  • Defense In Depth — Stacking multiple independent protective layers between threat and asset so that only a correlated breach across all layers produces total loss.
  • Dependency Distribution Concentration — How a system's dependency weight is distributed across providers — concentrated or spread — is a structural property that bounds its fragility independent of its own defenses.
  • Escape and Leakage — Constrained quantities exit through unintended pathways.
  • Failure Mode and Effects Analysis (FMEA) — Identify failure modes.
  • Loss And Damage — The residual harm that passes through after every layer of defense, treated as its own accounting unit and assigned a bearer and a policy.
  • Risk — Exposure to a known distribution of possible outcomes.
  • Risk Pooling — Aggregating many independent or weakly correlated exposures so that the variance of the pooled outcome shrinks below the sum of individual variances, letting participants share a more predictable collective risk.
  • Risk Transfer — Shifting an adverse-outcome distribution from one party to another for a price, so the loss lands on whoever can bear it best.
  • Speculative Bubble — Self-reinforcing price rise detached from fundamental value.
  • Structural Violence — Systemic harm.
  • Swiss Cheese Model (Layered Defense with Aligning Holes) — Catastrophe occurs only when a hazard finds a trajectory through a hole in every serial defensive layer at once, so the key variable is the correlation of holes across layers.
  • Systemic Risk — Risk that local failures propagate into system-wide collapse.
  • Vulnerability Decomposition — A system's vulnerability to a named stressor factors into exposure, sensitivity, and adaptive capacity, each admitting its own intervention family.
  • Weak Ties — Distant acquaintances that bridge otherwise separate social clusters.
