What Koali changes
← Back to the full MosaicKoali presents benefits, harms and uncertainty on the same evidence surface, segmented by relevant populations and time. Recommendations retain the evidence and criteria that produced them.

Koali response
Koali presents benefits, harms and uncertainty on the same evidence surface, segmented by relevant populations and time. Recommendations retain the evidence and criteria that produced them.
Real-world parallels
- COVID-19 vaccine guidance for fall 2026 — NACI
- Vaccines and autism — National Academies safety review
What success looks like
The relevant state remains visible across handoffs and time. • Responsibilities, unresolved questions and escalation paths are explicit.
Documented parallels show that the failure mechanism is real; they do not claim Koali would have changed a specific outcome.
The Risk Is Real. So Is the Benefit.
Trust improves when known harms are put at the right scale instead of denied or sensationalized.
The problem
Public debates often collapse into safe versus dangerous. Real decisions compare multiple risks: disease, intervention, age, prior exposure, comorbidities, uncertainty and personal preference.
What breaks
- Risk Distortion
- False Certainty
- Context Loss
- Noise Amplification
Who holds part of the picture
- public health
- clinicians
- community organizations
- affected people
With Koali
Koali presents benefits, harms and uncertainty on the same evidence surface, segmented by relevant populations and time. Recommendations retain the evidence and criteria that produced them.
Human authority
Authorized humans and institutions retain their existing legal, professional and democratic authority. Koali structures knowledge, coordination and traceability; it does not take sovereign or professional decisions.
What success looks like
- The relevant state remains visible across handoffs and time.
- Responsibilities, unresolved questions and escalation paths are explicit.
- The outcome produces reusable memory for the next comparable case.
Real-world parallels
NACI — COVID-19 vaccine guidance starting fall 2026
NACI distinguishes strong recommendations for higher-risk groups from discretionary access for others, illustrating population-specific benefit-risk guidance.

National Academies — Vaccines and Autism
The 2004 consensus review found that epidemiological evidence favored rejection of a causal relationship between MMR vaccination and autism.

Boundary
The documented cases illustrate analogous failure mechanisms. They do not establish that Koali would have prevented the event or guaranteed a different outcome.
