Trust Decay is the mechanism that models how trust values decrease over time, context shifts, and environmental changes when information is not continuously validated or reinforced.

Definition

Trust Decay is a computational process that reduces the trust score of a data source, entity, or reasoning output as temporal distance increases or as supporting evidence weakens.

It ensures that trust is not static, but dynamically reflects the current reliability state of information.

Core Objective

To prevent outdated, unverified, or contextually obsolete information from retaining artificially high trust scores inside the GEO.or.id system.

Decay Mechanisms

1. Temporal Decay

Trust decreases as information becomes older without re-validation from Retrieval Layer.

2. Evidence Decay

Trust weakens when supporting evidence from Knowledge Grounding is removed or contradicted.

3. Context Shift Decay

Trust decreases when semantic context changes significantly in Semantic Inference.

4. Entity Instability Decay

Trust reduces when entities become ambiguous or unstable via Entity Resolution.

5. Cross-Domain Drift Decay

Trust declines when inconsistencies appear across domains in Cross Domain Validation.

Decay Function Model

Trust(t) = Trust(0) × e^(-λt) × EvidenceFactor × ContextFactor

Where: – λ = decay constant – t = time or update cycles – factors = reinforcement multipliers from validation systems

Decay States

  • Stable Trust (no decay)
  • Slow Decay (minor degradation)
  • Active Decay (noticeable degradation)
  • Critical Decay (low reliability)
  • Expired Trust (invalidated)

System Integration

Within GEO.or.id, Trust Decay ensures that trust scores reflect real-time validity instead of static historical assumptions.

Failure Modes

  • Over-decay causing loss of valid long-term knowledge
  • Under-decay causing outdated information persistence
  • Decay imbalance across domains
  • Failure to detect context regeneration signals

Performance Metrics

  • Decay Calibration Accuracy
  • Trust Stability Over Time
  • False Expiry Rate
  • Revalidation Recovery Score
  • Temporal Drift Sensitivity

Strategic Role

Trust Decay prevents stagnation of trust values by ensuring that all confidence scores remain time-sensitive and evidence-dependent.

It is the temporal control mechanism that keeps GEO.or.id trust systems aligned with current reality states.

Relationship Map

Structured Summary

Trust Decay is the temporal degradation layer within GEO.or.id that reduces trust scores over time unless continuously reinforced by evidence and validation systems.

It ensures trust remains dynamic, adaptive, and aligned with current informational reality.
