Bias control architecture

The controls are external to any single specialty lens.

Mitigations that prevent any one specialty knowledge base from over-framing undiagnosed symptoms. The core idea: a biased lens should never be the thing that reviews itself.

Every mitigation below answers one question — why external? — because a control that lives inside a specialty lens inherits that lens's blind spots.
BM-1

Framing firewall

Prevents any specialty or condition from priming the model during undiagnosed intake; uses neutral language and base-rate context.

Why external? Different framing is applied before any specialty context is used.
BM-2

External checker

A second, independent model — using a method not optimized for prevalence in any single specialty.

Why external? An independent lens can see what the primary lens misses.
BM-3

Release gate

Cases are blocked unless release criteria across diverse domains are met (red flags cleared, consistency checks).

Why external? The gate sits outside the model to avoid in-model bias.
BM-4

Countersignal library

A library of common benign explanations mapped to symptom clusters, to keep relief explanations in view.

Why external? Introduces non-anchor explanations the model may miss.
BM-5

Human in the loop

High-uncertainty or high-impact cases are reviewed by a clinician before any next step is recommended.

Why external? A human decides — not the model.
BM-6

Offline measurement

Continuously measure over-framing, specialty drift, and error across populations before release.

Why external? Measured on data, not judged by the model itself.
BM-7

Audit & monitoring

Monitor real-world use for over-use of one specialty, blind spots, and patient-safety signals.

Why external? Observed in the wild, not self-reported by the model.
Fail-safe

Graceful fallback

If any gate fails, the system stays in the neutral PCP handoff path. Specialty reasoning is not used.

Safety is never traded for specificity.
What defines a good "generalist"

Anchors on base rates. Knows its lane.

  • Anchors on base rates — leads with what's common.
  • Calibrated, not confident — distinguishes evidence from possibility.
  • Has breadth — reasons across all of medicine.
  • Resists anchoring — seeks disconfirming evidence.
  • Grounds its reasoning — every claim traceable to evidence.
  • Knows its lane — defers the decision to a clinician; produces a differential, not a verdict.
Infrastructure note

Reuses validated infrastructure

Guided Care reuses and extends existing validated multidisciplinary infrastructure for differential balancing, with graceful fallback to a single disinterested reviewer if needed.

The bias controls are orthogonal to the safety floor — both run independently, and neither depends on the other to function.
