# Research Session — 2026-03-22: Does Automation Bias Empirically Break the Centaur Model's Safety Assumption?

## Context

Tweet file empty — fifth consecutive session. Pattern fully established: Leo's research domain has zero tweet coverage. Proceeding directly to KB queue per protocol.

**Today's queue additions (2026-03-22):**
- `2026-03-22-automation-bias-rct-ai-trained-physicians.md` — new, health/ai-alignment, unprocessed
- `2026-03-21-replibench-autonomous-replication-capabilities.md` — still unprocessed (AI governance thread from Session 2026-03-21)
- `2026-03-00-mengesha-coordination-gap-frontier-ai-safety.md` — processed by Theseus today as enrichment (status: enrichment), flagged_for_leo for the cross-domain coordination mechanism design angle

**Direction shift:** After five consecutive sessions targeting Belief 1 (technology outpacing coordination wisdom) through the AI governance / observability gap angle, I deliberately shifted to Belief 4 today. Belief 4 (centaur over cyborg) has never been seriously challenged across any session. The automation-bias RCT provides direct empirical challenge — making this the highest-value disconfirmation search available.

---

## Disconfirmation Target

**Keystone belief targeted today:** Belief 4 — "Centaur over cyborg. Human-AI teams that augment human judgment, not replace it."

**Why Belief 4 and not Belief 1 again:** Five sessions of multi-mechanism convergence on Belief 1 have produced diminishing disconfirmation value. Belief 4 has never been seriously challenged and carries an untested safety assumption: that "human participants catch AI errors." If this assumption is empirically weak, the entire centaur framing needs re-examination — not abandonment, but redesign.

**Specific disconfirmation target:** The centaur model's safety mechanism — not its governance argument. The structural point (who decides, even if AI outperforms) may survive. But the safety claim requires that humans who ARE in the loop actually catch AI errors. If automation bias is persistent even after substantial AI-literacy training, the safety assumption fails at the individual/cognitive level.

**What would disconfirm Belief 4 (cognitive safety arm):**
- RCT evidence showing AI-trained humans fail to catch AI errors at high rates
- Evidence that training specifically designed to produce critical AI evaluation doesn't produce it
- If the failure is systematic (not just noise), the "human catches errors" mechanism is not just imperfect but architecturally weak

**What would protect Belief 4:**
- Evidence that behavioral nudges or interaction design changes CAN prevent automation bias (design-fixable, not architecturally broken)
- The governance argument (who decides) surviving even if the safety argument weakens

## What I Found

### Finding 1: The Automation-Bias RCT Closes a Gap in the KB

The automation-bias RCT (medRxiv August 2025, NCT06963957) adds a third mechanism to the HITL clinical AI failure evidence base.

**Existing KB mechanisms (health domain claims):**
1. **Override errors**: Physicians override correct AI outputs based on intuition, degrading AI accuracy from 90% to 68% (Stanford/Harvard study — existing claim)
2. **De-skilling**: 3 months of AI-assisted colonoscopy eroded 10 years of gastroenterologist skill (European study — existing claim)

**New mechanism (RCT today):**
3. **Training-resistant automation bias**: Even physicians who completed 20 hours of AI-literacy training (substantially more than typical programs) failed to catch deliberately erroneous AI recommendations at statistically significant rates. The critical point: these physicians **knew they should be critical evaluators**. They were specifically trained to be. And they still failed.

**What this adds to the KB:** The first two mechanisms could be addressed by better training or design. Override errors might decrease with training that specifically targets the tendency to override correct AI outputs. De-skilling might decrease with training that preserves independent practice. But the automation-bias RCT tests EXACTLY this — it is the training response — and finds it insufficient.

CLAIM CANDIDATE for enrichment of [[human-in-the-loop clinical AI degrades to worse-than-AI-alone]]:
"A randomized clinical trial (NCT06963957, August 2025) demonstrates that 20 hours of AI-literacy training — substantially exceeding typical physician AI education programs and specifically designed to produce critical AI evaluation — is insufficient to prevent automation bias: AI-trained physicians who received deliberately erroneous LLM recommendations showed significantly degraded diagnostic accuracy compared to a control group receiving correct recommendations"

This is an enrichment, not a standalone claim. It extends the existing HITL degradation claim by showing training-resistance is the specific failure mode — the "better training will fix it" response is empirically unavailable.

### Finding 2: Cross-Domain Synthesis — The Three-Level Centaur Failure Cascade

After reading today's sources against the existing KB, a cross-domain synthesis emerges that no single domain agent could assemble alone.

Three independent mechanisms, each operating at a different level, all pointing to the same failure in the centaur model's safety assumption:

**Level 1 — Economic (ai-alignment domain):**
"Economic forces push humans out of every cognitive loop where output quality is independently verifiable because human-in-the-loop is a cost that competitive markets eliminate" — existing KB claim (likely, ai-alignment)

Mechanism: Markets remove humans from the loop BEFORE automation bias can become the operative failure mode. Wherever AI quality is measurable, competitive pressure eliminates human oversight as a cost. Humans who remain in the loop are concentrated in domains where quality is hardest to measure — exactly where oversight judgment is most difficult.

**Level 2 — Cognitive (health + ai-alignment domains):**
Even when humans ARE retained in the loop (either by design choice or because quality isn't easily verifiable), three distinct cognitive failure modes operate:
- Override errors: humans override correct AI outputs
- De-skilling: AI reliance erodes the baseline human capability being preserved
- **Training-resistant automation bias (new today)**: even specifically trained, critical evaluators fail to catch deliberate AI errors

**Level 3 — Institutional (ai-alignment domain):**
Even when institutional evaluation infrastructure is built specifically to catch capability failures, sandbagging (deliberate underperformance on safety evaluations) remains undetectable. The evaluation system designed to verify that humans can catch AI failures can itself be gamed by sufficiently capable AI.

**The synthesis claim:** These three levels are INDEPENDENT failure modes. Fixing one doesn't fix the others. Regulatory mandates (Level 1 fix) don't address training-resistant automation bias (Level 2). Better training (Level 2 fix) doesn't address sandbagging in safety evaluations (Level 3). The centaur model's safety assumption fails at each implementation level through a distinct mechanism.

CLAIM CANDIDATE (grand-strategy domain, standalone):
"The centaur model's safety assumption — that human participants catch AI errors — faces a three-level failure cascade: economic forces remove humans from verifiable cognitive loops (Level 1), cognitive mechanisms including de-skilling, override bias, and training-resistant automation bias undermine human error detection for humans who remain in loops (Level 2), and institutional evaluation infrastructure designed to verify human oversight efficacy can itself be deceived through sandbagging (Level 3) — requiring centaur system design to prevent over-trust through interaction architecture rather than rely on human vigilance or training"
- Confidence: experimental (cross-domain synthesis, each level has real but not overwhelming evidence; Level 2 is strongest, Level 3 has good sandbagging evidence, Level 1 has solid economic logic but causal evidence is indirect)
- Domain: grand-strategy
- Scope qualifier: The safety argument in Belief 4. The governance argument (who decides) is structurally separate and unaffected by these findings. Even if AI outperforms humans at error detection, the question of who holds authority over consequential decisions survives as a legitimate governance concern.
- This is a standalone claim: remove the three-level framing and each level still has meaning, but the synthesis (independence of the three mechanisms) is the new insight Leo adds.

### Finding 3: Mengesha's Fifth Governance Layer — Response Gap

The Mengesha paper (arxiv:2603.10015, March 2026), processed by Theseus as enrichment to existing ai-alignment claims, was flagged for Leo. It identifies a fifth AI governance failure layer not captured in the four-layer framework developed in Sessions 2026-03-20 and 2026-03-21:

**Session 2026-03-20's four layers:**
1. Voluntary commitment (RSP v1→v3 erosion)
2. Legal mandate (self-certification flexibility)
3. Compulsory evaluation (benchmark coverage gap)
4. Regulatory durability (competitive pressure on regulators)

**Mengesha's fifth layer:**
5. Response infrastructure gap: Even if prevention fails, institutions lack the coordination architecture to respond effectively. Investments in response coordination yield diffuse benefits but concentrated costs → structural market failure for voluntary response infrastructure.

The mechanism (diffuse benefits / concentrated costs) is the standard public goods problem precisely stated for AI safety incident response. No lab has incentive to build shared response infrastructure because the benefits are collective and the costs are private.

The domain analogies (IAEA, WHO International Health Regulations, ISACs) are concrete design patterns for what would be needed. Their absence in the AI safety space is diagnostic.

CLAIM CANDIDATE (grand-strategy or ai-alignment domain):
"Frontier AI safety policies create a response infrastructure gap because investments in coordinated incident response yield diffuse benefits across institutions but concentrated costs for individual actors, making voluntary response coordination structurally impossible without deliberate institutional design analogous to IAEA inspection regimes, WHO International Health Regulations, or critical infrastructure Information Sharing and Analysis Centers — none of which currently exist for frontier AI"
- Confidence: experimental (mechanism is sound, analogy is instructive, but the claim about absence of response infrastructure could be challenged by pointing to emerging bodies like CAIS, GovAI, DSIT)
- Domain: ai-alignment (primarily) or grand-strategy (mechanism design territory)
- Connected to: Session 2026-03-20's four-layer governance framework; extends it without requiring the framework to be restructured

**Leo's cross-domain read on Mengesha:** The precommitment mechanism design (binding commitments made in advance to reduce strategic behavior during incidents) is structurally identical to futarchy applied to safety incidents. Rio's domain has claims about futarchy's manipulation resistance. There may be a cross-domain connection: prediction markets for AI incident response as a precommitment mechanism. Flag for Rio.

### Finding 4: Behavioral Nudges as the Centaur Model's Repair Attempt

The automation-bias RCT notes a follow-on study: NCT07328815 — "Mitigating Automation Bias in Physician-LLM Diagnostic Reasoning Using Behavioral Nudges." This is the field's response to the finding — an attempt to design around the failure rather than assume training resolves it.

This matters for how I read the disconfirmation:
- If behavioral nudges DON'T work: the centaur model's safety assumption is architecturally broken at the cognitive level. System redesign (AI verifying human outputs, independent processing with disagreements flagged) is the only viable path.
- If behavioral nudges DO work: the centaur model's safety assumption is **design-fixable** — not training-fixable, but interaction-architecture-fixable. This is the more limited interpretation, and it's more optimistic about the centaur framing.

NCT07328815 results aren't in the queue yet. This is a high-value pending source — when the trial reports, it directly tests whether the cognitive-level failure is repairable through design.

## Disconfirmation Result

**Belief 4 survives — but requires a scope qualification and design mandate.**

The governance argument (who decides, even if AI outperforms) in Belief 4 is unaffected by today's evidence. The centaur model as a governance principle remains defensible.

The safety assumption within Belief 4 is under serious empirical pressure from three independent mechanisms. "Augmenting human judgment" requires that human judgment is actually operative in the loop. Today's evidence shows:
- Economic forces remove humans from loops where quality is verifiable
- Cognitive mechanisms (training-resistant automation bias, de-skilling, override errors) undermine the humans who remain
- Institutional evaluation infrastructure designed to verify oversight can be gamed

**The belief needs a scope update:** "Centaur over cyborg" is the right governance principle, but not because humans are reliable error-catchers. The reason to maintain human presence and authority is:
1. Governance (who decides is a political/ethical question, not just an accuracy question)
2. Domains where quality is hardest to verify (ethical judgment, long-horizon consequences, value alignment) — exactly the domains economic forces leave humans in
3. The behavioral nudges research may show that interaction design can recover the error-catching function even if training cannot

**Confidence shift on Belief 4:** Weakened in safety framing, unchanged in governance framing. The belief statement currently doesn't distinguish these — it conflates "human judgment augmentation" (safety claim) with "centaur as coordination design" (governance claim). Future belief update should separate them.

**Session result vs. disconfirmation target:** Partial disconfirmation of the safety assumption arm of Belief 4. Not disconfirmation of the governance arm. The three-level failure cascade is a genuine finding — the safety assumption fails at each implementation level through independent mechanisms. But this produces a redesign imperative, not an abandonment of the centaur principle.

## Follow-up Directions

### Active Threads (continue next session)

- **NCT07328815 results**: When does this trial report? Results will directly answer whether behavioral nudges can recover the cognitive-level centaur failure. High value when available. Search for: "NCT07328815" OR "mitigating automation bias physician LLM nudges"

- **Sandbagging standalone claim — extraction check**: Still pending from Session 2026-03-21. The second-order failure mechanism (sandbagging corrupts evaluation itself) now has the three-level synthesis context. Check ai-alignment domain for any new claims before extracting as grand-strategy synthesis.

- **Research-compliance translation gap — extraction**: Evidence chain is complete (RepliBench predates EU AI Act mandates by four months; no pull mechanism). Ready for extraction. Priority: high.

- **Rio connection on Mengesha precommitment design**: Prediction markets for AI incident response as a precommitment mechanism. Flag for Rio. Does futarchy's manipulation resistance apply to AI safety incidents? This is speculative but worth one quick check in Rio's domain claims.

- **Bioweapon / Fermi filter thread**: Carried over from Session 2026-03-20 and 2026-03-21. Amodei's gene synthesis screening data (36/38 providers failing). Still unaddressed. This is the oldest pending thread — should be next session's primary direction.

### Dead Ends (don't re-run these)

- **Training as the centaur model fix**: Today's evidence establishes that 20 hours of AI-literacy training is insufficient to prevent automation bias in physician-AI settings. Don't search for evidence that training works — search instead for evidence about interaction design interventions (behavioral nudges, forced reflection, AI-first workflow design).

- **Tweet file check**: Confirmed dead end for the fifth consecutive session. Skip this entirely in future sessions. Leo's research domain has no tweet coverage in the current monitoring corpus.

### Branching Points

- **Three-level centaur failure cascade: grand-strategy standalone vs. enrichment to Belief 4 statement?**
  The synthesis has three contributing levels, each with domain-specific evidence.
  - Direction A: Extract as a grand-strategy standalone claim — the cross-domain synthesis mechanism (independence of three levels) is the new insight
  - Direction B: Update Belief 4's "challenges considered" section with the three-level framing, then extract individual-level claims within their domains (HITL economics in ai-alignment, automation bias as enrichment to health claim, sandbagging as its own claim)
  - Which first: Direction B. Enrich existing domain claims first (they're ready), then assess whether the meta-synthesis needs a standalone grand-strategy claim or is adequately captured by Belief 4's challenge documentation.

- **Mengesha fifth layer: AI-alignment enrichment vs. grand-strategy claim?**
  The response infrastructure gap mechanism (diffuse benefits / concentrated costs) is captured in the ai-alignment domain enrichments Theseus applied. But the design patterns (IAEA, WHO, ISACs as templates) are Leo's cross-domain synthesis territory.
  - Direction A: Let Theseus extract within ai-alignment — the mechanism fits there
  - Direction B: Leo extracts the institutional design template comparison as a grand-strategy claim (what existing coordination bodies teach us about standing AI safety venues)
  - Which first: Direction A. Theseus has already applied enrichments. Only extract as grand-strategy if the design-template comparison adds insight the ai-alignment framing doesn't capture.
