PSDA.2:6 - Bias-Annotation
Scope: provisional problem boundaries for a named decision-support use. Lenses: Gov keeps inclusion, jurisdiction, and choice authority separate; Arch exposes dependencies on the cut; Onto/Epist distinguishes situation, formulation, ordinary boundary, declared U.Scope, and evidence; Prag seeks the smallest usable scope; Did makes exclusions and reopen cues readable without a specialist notation.
| Recurring bias | Likely drift | Repair |
|---|---|---|
| sponsor-boundary bias | The brief’s perimeter becomes unquestionable. | Challenge it with bearers, formulations, actions, evidence, authority, and reversal. |
| map-completeness bias | More nodes are treated as better scope. | Require each included dimension to change the receiving use. |
| data-availability bias | Available variables define the problem. | Record excluded concerns and evidence gaps independently of the model. |
| box-as-ontology bias | A drawn perimeter is treated as proof of a System boundary or exact scope membership. | State the ordinary decision-support cut; use the direct engineering practice for a System-boundary claim and A.2.6 for contextual membership when either is needed. |
| exclusion-as-falsehood bias | Outside the current inquiry becomes “does not matter”. | Record material exclusions, uncertainty, consequence, and reopen basis. |
| boundary-freeze bias | Later contrary evidence is absorbed without revising scope. | Reopen the smallest affected dimension and dependent results. |
