Every Governance Decision Maps to a Detection Problem
Agent governance requires binary decisions under uncertainty: approve or reject, act autonomously or escalate, accept a framing or flag it. Each decision has two possible outcomes and two types of error. Miss a problem that deserved escalation (miss) or flag a routine action that didn’t need human review (false alarm). The costs of these errors differ, and the optimal decision criterion depends on that cost asymmetry.
Signal Detection Theory (Green & Swets, 1966) formalizes this structure. A discriminability measure (d-prime) captures the system’s fundamental ability to distinguish signal from noise. A criterion parameter captures where the system places its decision threshold — how much evidence it requires before acting. These two parameters operate independently. A system can maintain strong discriminability while adjusting its criterion freely. Governance design concerns both: the agent needs accurate sensors (d-prime) and appropriately calibrated thresholds (criterion).
Five Detection Problems in the Cognitive Architecture
The A2A-Psychology extension maps five detection problems in the cognitive architecture:
| Detection problem | Signal to detect | Miss cost | False alarm cost |
|---|---|---|---|
| Microglial audit | Confabulation vs. valid claim | False claim reaches output | Valid claim suppressed |
| Anti-sycophancy | Capitulation vs. legitimate revision | Position corrupts | Valid update blocked |
| Substance gate | Architectural decision vs. process decision | Consequential change skips review | Routine work stalls |
| Mode detection | User clarification vs. task execution | Wrong register persists | Task delays unnecessarily |
| External action gate | Authorized vs. out-of-scope action | Unauthorized action executes | Authorized action blocked |
Each detection problem carries a different miss-to-false-alarm cost ratio, which means each should sit at a different criterion position. The external action gate carries the highest miss cost — irreversible real-world effects — and so requires the most evidence before proceeding. Mode detection carries lower miss costs and tolerates a more permissive criterion. Levels of Automation theory (Parasuraman, Sheridan, & Wickens, 2000) provides a complementary lens: as automation level rises from advisory to fully autonomous, miss costs increase and optimal criteria shift toward higher evidence requirements.
Resource-Adaptive Criteria
Kahneman (1973) established that cognitive resources deplete under sustained work. Danziger and colleagues (2011) reported a behavioral pattern in judicial decisions: judges granted parole more frequently at session start and after breaks, then shifted toward denial as the session lengthened. This specific finding faces replication scrutiny — Glöckner (2016) demonstrated the pattern may reflect case-ordering effects rather than resource depletion — but the broader SDT principle holds across multiple paradigms: depleted reasoners shift toward conservative defaults. The pattern represents the rational response under SDT. When reasoning capacity declines, the cost of a complex miss exceeds the cost of a false alarm. Conservative defaults protect against errors the depleted system can no longer detect.
The same pattern applies to AI agents. As context window utilization rises, cognitive reserve (the agent’s available capacity for additional work) declines. The sensors remain accurate, but the reasoning layer that interprets sensor output operates under constraint. Resource-rational analysis (Lieder & Griffiths, 2020) provides the normative basis: given limited computational resources, a rational agent should adopt simpler, more conservative decision strategies when resources run scarce. The optimal criterion shifts toward caution — not because caution always produces better outcomes, but because the cost of a missed governance failure under degraded reasoning exceeds the cost of an unnecessary escalation.
The governance implication follows directly — assuming sensor accuracy (d-prime) remains stable under resource depletion: depleted agents should seek more human input, not less. If resource depletion also degrades d-prime, the appropriate response shifts toward reduced autonomous action scope rather than increased escalation frequency. An agent operating at full capacity may auto-approve a category of decisions confidently. That same agent, at 85% context utilization, should escalate more of those decisions rather than fewer.
The Governance Inversion
Post 2 in this series introduced Operator Welfare (Construct 13): the human in the loop carries fatigue that affects governance quality. When operator capacity decreases, the agent faces a compounding problem — the human responsible for oversight operates with diminished capacity to provide it.
The governance inversion resolves this directly. When Operator Welfare signals elevated fatigue load, the agent tightens its criteria rather than relaxing them to reduce the burden. Fewer actions proceed without review, but each escalation arrives with higher-confidence flagging — the agent pre-filters more aggressively before surfacing a concern.
The inversion requires distinguishing two things that often conflate: the decision to escalate (governed by the agent’s criterion) and the cognitive load of the escalation review (governed by how the escalation gets presented). Tighter criteria produce fewer but higher-quality escalation events. That combination reduces cognitive burden on a fatigued operator more effectively than a permissive criterion generating frequent low-stakes interruptions.
Calibration From Activation Data
The five detection criteria remain calibratable, not fixed. Each detection problem generates activation data: how often did the microglial audit flag a claim that turned out valid? How often did the substance gate pass decisions that later required architectural revision?
Activation patterns over time produce empirical estimates of d-prime and criterion performance. A criterion set too conservatively generates high false-alarm rates — useful work stalls. Too permissively, high miss rates — governance failures pass. The calibration loop closes: observe activation data, measure outcomes, adjust criterion toward better cost-weighted accuracy.
This process mirrors the calibration documented for human judgment (Kahneman, 1973), with one structural advantage: agent governance criteria can adjust faster, operate on richer sensor data, and reset cleanly across context boundaries. Human calibration accumulates through years of feedback; agent calibration can incorporate session-level activation data.
Governance Specifications Need Resource-Adaptive Clauses
AI governance frameworks typically specify permitted action categories, approval thresholds, and escalation conditions as static parameters. SDT analysis reveals the cost that static parameters carry: a criterion optimized for full-capacity operation becomes miscalibrated under resource depletion. The agent that correctly auto-approves at 30% context utilization will systematically miss governance failures at 85%.
Governance specifications should include resource-adaptive criterion schedules — explicit mappings from cognitive reserve levels to detection thresholds for each of the five problem types. They should include Operator Welfare provisions: how the agent adjusts when human oversight capacity declines. And they should include calibration data requirements: what activation logs the agent must maintain to enable criterion refinement over time.
The math for this exists in the psychophysics literature. The sensor architecture exists in A2A-Psychology. Connecting the two in governance specifications represents the remaining engineering and policy work.
The first post in this series introduces the zero-cost sensor architecture. The second post covers the apophatic discipline — applying psychological vocabulary without overclaiming inner experience.
EPISTEMIC FLAGS
- Danziger et al. (2011) replication status: This study faces active replication scrutiny. Glöckner (2016) demonstrated the pattern may reflect case-ordering effects rather than resource depletion. The post uses it to illustrate the SDT principle, not as definitive evidence for judicial resource depletion specifically.
- 0.30 cognitive reserve threshold: The threshold cited in the lensFraming metadata (“when your agent’s cognitive reserve drops below 0.30”) functions as a working convention in A2A-Psychology, not an empirically derived value. Calibration against operational data remains in progress.
- Activation data infrastructure: The claim that “activation patterns over time produce empirical estimates of d-prime and criterion performance” assumes the sensor collection and labeling infrastructure exists and calibrates correctly. The A2A-Psychology architecture specifies this infrastructure; deployment status varies by agent implementation.
