When Decisions Outlive Their Justification:
Introducing Decision Epistemology
Public introduction of Decision Epistemology as a developing research programme.
When decisions outlive their justification.
Decision Epistemology is an emerging research programme concerned with the epistemic integrity of decision systems over time.
How does a decision system know that the picture it continues to act upon still deserves belief?
Evidence, then judgment, then decision.
Changed conditions, an unresolved question, continued action.
What still warrants continuation?
A decision may have been justified
when it was made without thereby
remaining justified now.
- Evidence may be sufficient.
- Assumptions may be defensible.
- Authority may be legitimate.
- The approved object may be well understood.
- Evidence may have changed.
- Assumptions may no longer hold.
- The object may have evolved.
- Authority may still continue.
HISTORICAL JUSTIFICATION does not equal CURRENT JUSTIFICATION
Decision Epistemology studies the temporal relationship between prior decision, changing conditions and present justification.
prior decisionchanging conditionspresent justification
An analytical relation, not a universal process architecture.
Decision Epistemology is not presented as a replacement for decision theory, Human Factors, Situation Awareness, safety science, assurance, organisational sensemaking, resilience or governance.
The scientific question is narrower: does a decision-centred analysis of continued justification explain something that strong existing approaches do not already explain sufficiently?
The burden is on the programme to demonstrate residual value.
Six current question families.
Temporal justification
When does a previously justified decision cease to have a sufficient current basis?
Reopening
What kind of change should force a continuing decision to become examinable again?
Object applicability
When does continuity of workflow cease to establish continuity of the authorised object?
Uncertainty
How should unresolved sufficiency affect continued authority?
Timing
Can correction arrive before consequence becomes practically fixed?
Residual value
Does a decision-centred representation add anything that stronger existing architectures do not already provide?
Things that should not collapse into one another.
- Historical justificationdoes not equalCurrent justification
- Operational continuitydoes not equalCurrent justification
- Recognition of changedoes not equalReopening
- Governance responsedoes not equalRuntime permission
- Permissiondoes not equalJustification
- Outcomedoes not equalDecision quality
These are analytical distinctions, not a universal process architecture.
Designed to be capable of losing.
If an established architecture explains the same function better
If a construct adds no residual value
If the research object survives while a construct fails
Preserve the question, not the terminology.
A programme that cannot lose is not functioning as a research programme.

Under peer review does not mean accepted, published or validated.
Current construct status
- Decision-Continuation Warrant
- Candidate decision-centred application profile
- Decision Justification State
- Provisional classification
- Authorised-Object Continuity
- Candidate interface architecture
None is currently presented as validated.
Next scientific direction
- Comparator testing
- Construct discrimination
- Bounded empirical investigation
The programme does not depend on any one current construct surviving in its present form.
The terminology is provisional.
The problem is examinable.
The evidence must decide.
Research developed in public —
but not validated by publicity.
Public discussion is used for challenge, hypothesis generation, provenance and intellectual-development record. It is not treated as empirical validation.
When Decisions Outlive Their Justification:
The Change Was Real.
The Decision Stayed Closed.
Public research note on recognised change, reopening and continued decision status.
Nothing changed in the system.
The system was no longer authorised.
Public discussion is used for challenge, hypothesis generation and provenance. It is not treated as empirical validation, consensus or independent replication.

Research programme
What makes continued reliance on prior decisions epistemically and institutionally warranted as conditions change?
Decision Epistemology is the scientific research programme.
RELATED.
NOT IDENTICAL.
Applied design and practice
How consequential decision systems can remain challengeable, revalidatable and operationally correctable over time.
Decision Engineering is informed by Decision Epistemology but is not reducible to it.
Applied practice does not validate the scientific programme.
Decision Engineering also draws from Human Factors, systems engineering, operations research, safety science, assurance, governance, organisation design and decision science.
