Pareto frontier

2Instrument

The options that no other option beats on every criterion at once, so improving one criterion means worsening another. Plot it before scalarizing; weights then choose a point on it.

Also called: Pareto-optimal

Defined in

Handbook · InstrumentAggregation geometryWeighted means assume strengths can offset weaknesses; gates assert some failures are fatal. How criteria combine is a normative decision, so make it explicitly.
Aggregation geometry
The rule that combines criterion-level signals into a decision: weighted mean, conjunctive gate, lexicographic order, Pareto vector, or tail-risk rule.
