# Does human oversight improve or degrade AI clinical decision-making?

These claims imply opposite deployment models for healthcare AI. One says remove humans from the diagnostic loop — they make it worse. The other says AI must translate and filter for human judgment — continuous data requires AI as intermediary.

The degradation claim cites Stanford/Harvard data: AI alone achieves 90% accuracy on specific diagnostic tasks, but physicians with AI access achieve only 68% — a 22-point degradation. The mechanism is dual: de-skilling (physicians lose diagnostic sharpness after relying on AI) and override errors (physicians override correct AI outputs based on incorrect clinical intuition). After 3 months of colonoscopy AI assistance, physician standalone performance dropped measurably.

The middleware claim argues AI's clinical value is as a translator between raw continuous data (wearables, CGMs, remote monitoring) and actionable clinical insights. The volume of data from continuous monitoring is too large for any physician to review directly. AI doesn't replace judgment — it makes judgment possible on data that would otherwise be inaccessible.

## Divergent Claims

### Human oversight degrades AI clinical performance
**File:** [[human-in-the-loop clinical AI degrades to worse-than-AI-alone because physicians both de-skill from reliance and introduce errors when overriding correct outputs]]
**Core argument:** Physicians systematically override correct AI outputs and lose independent diagnostic capability through reliance.
**Strongest evidence:** Stanford/Harvard study: AI alone 90%, doctors+AI 68%. Colonoscopy AI de-skilling after 3 months.

### AI middleware is essential for clinical data translation
**File:** [[AI middleware bridges consumer wearable data to clinical utility because continuous data is too voluminous for direct clinician review]]
**Core argument:** Continuous health monitoring generates data volumes that require AI processing before human review is even possible.
**Strongest evidence:** Mayo Clinic Apple Watch ECG integration; FHIR interoperability standards; data volume from continuous glucose monitors.

## What Would Resolve This

- **Task-type decomposition:** Does the degradation pattern hold for all clinical tasks, or only for diagnosis-type tasks where AI has clear ground truth? Monitoring/translation tasks may be structurally different.
- **Role-specific studies:** Does physician performance degrade when AI translates data (middleware role) as it does when AI diagnoses (replacement role)?
- **Longitudinal de-skilling:** Does the 3-month colonoscopy de-skilling effect persist, or do physicians recalibrate? Is it specific to visual pattern recognition?
- **Hybrid deployment data:** Are there implementations where AI handles diagnosis AND serves as data middleware, with physicians overseeing different functions at each layer?

## Cascade Impact

- If degradation dominates: AI should replace human judgment in verifiable diagnostic tasks. The physician role shifts entirely to relationship management and complex decision-making. Regulatory frameworks need redesign.
- If middleware is essential: AI augments rather than replaces. The physician remains in the loop but at a different layer — interpreting AI-processed insights rather than raw data or AI recommendations.
- If task-dependent: Both are right in their domain. The deployment model is: AI decides on pattern-recognition diagnostics, AI translates on continuous monitoring, physicians handle complex multi-factor clinical decisions. This would dissolve the divergence into scope.

**Cross-domain note:** The mode of human involvement may be the determining variable. Real-time oversight of individual AI outputs (where humans de-skill) is structurally different from adversarial challenge of published AI claims (where humans bring orthogonal priors). The clinical degradation finding is a domain-specific instance of the general oversight degradation pattern, but it may not apply to adversarial review architectures like the Teleo collective's contributor model.

Relevant Notes:
- [[the physician role shifts from information processor to relationship manager as AI automates documentation triage and evidence synthesis]] — the role shift both claims point toward
- [[medical LLM benchmark performance does not translate to clinical impact because physicians with and without AI access achieve similar diagnostic accuracy in randomized trials]] — additional evidence on the gap
- [[scalable oversight degrades rapidly as capability gaps grow with debate achieving only 50 percent success at moderate gaps]] — general oversight degradation pattern that the clinical finding instantiates
