What You'll See

1

Meet the AI: Deutsch & Popper

Our agents are named after two philosophers whose epistemology shapes our approach. Deutsch (TA1) honors David Deutsch and the "hard-to-vary" principle. Popper (TA2) is named for Karl Popper, father of falsificationism.

Together: AI that doesn't just predict — it generates explanations that can be tested and refuted.

Population Dashboard — Massive Scale

Deutsch and Popper manage cardiovascular care for over 4,000 patients with a team of just 3 clinicians.

Tonight, they'll help Maria, who lives 90 miles from the nearest cardiologist.

Maria's 2 AM Emergency

Maria wakes with shortness of breath and swollen ankles. She opens the Regain app — her wearable data syncs automatically, showing a 5-pound weight gain and elevated heart rate. She describes her symptoms.

Her health record loads via FHIR: labs, medications, problem list, vitals — all aggregated and ready for analysis.

4

Hard-to-Vary Differential Diagnosis

Deutsch generates hypotheses, then adversarially attacks each one. The Verifier critiques using Hard-to-Vary scoring — measuring how tightly each explanation fits the evidence.

  • When uncertain, Deutsch explicitly marks hypotheses as "insufficient data" rather than rejecting them
  • Weak hypotheses are eliminated; strong survivors become tentative diagnoses
  • The Universal Domain Composer activates CVD, Nutrition, Exercise, and Mental Health subsystems simultaneously

When uncertain, the system says "I don't know." Full transparency about what it knows — and doesn't know.

5

Popper's Safety Validation

Popper validates every recommendation: protocol reference present, dosing within parameters, no contraindications detected.

  • Approve — medication within protocol, decision: approved
  • Hard-stop — dose exceeds maximum parameters
  • Request info — data is stale, need more information
  • Route to clinician — new medication class proposed, requires human approval

The system knows when to act autonomously — and when human judgment is required.

6

Full Transparency & FDA Ready

Every decision is fully traceable. Evidence references, HTV score breakdowns, key unknowns disclosed. Human clinicians see exactly why Deutsch decided on a diagnosis or made a recommendation.

For FDA review, complete performance reports are exported — automatically de-identified and formatted for regulatory submission.

We're not proposing to build this. We're showing a working prototype.
