Three data-heavy articles share a hard-won caution: **a raw signal means nothing until it is interpreted in context — and much of what looks like a problem is noise.**

- **A111** names it: [[concept-operational-noise|operational noise]] makes schedules *look* unstable even when systems work; only real analytics ([[concept-lasso-regression-workforce|LASSO]]) can separate noise from a genuine structural driver.
- **A112** generalizes it to people: [[claim-contextual-performance-variation|a performance dip may be fatigue, a broken workflow, or coordination]] — not a capability deficit — which is why sensing must move "from the *what* to the *why*."
- **A113** adds the behavioral layer: [[concept-ai-friction|friction signals]] (rephrasing, arguments, overrides) must be read as symptoms of design, not user failure ([[claim-overrides-signal-design-flaws]]).

**The shared discipline** is the aviation-style move A112 imports: interpret signals against workflow, fatigue, and environment rather than assigning individual blame. This is the interpretive counterpart to [[cross-measurement-artifact-vs-reality]] (which warns *which* metrics mislead) and the safeguard that makes [[cross-algorithm-as-guide-human-judgment|human override]] intelligent rather than arbitrary. Without it, the [[cross-data-foundation-prerequisite|data foundation]] produces confident nonsense.
