The Concord Method

Multiple independent AI agents work in coordinated teams. A research pair analyzes published medical literature and compares interpretations. A writing team translates findings into patient-accessible language. An editorial review verifies citation accuracy. A verification swarm traces every claim back to its PubMed source.

Cooperative AI agents working in pairs, using a notation system that forces uncertainty to be visible — they can’t hide what they don’t know from each other.
