CORE DEFINITION

Set up multiple layers of defense mechanisms, so that if one layer is breached, the next layer still blocks, without relying on a single line of defense.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Redundant protection. Assume each layer will fail; multiple layers stacked make the overall failure probability approach zero.

anchor

Anchor fast decisions

Layered defense; even if any single layer is breached, subsequent lines remain, using redundancy and diversity to improve overall resilience.
