Five live theories

Each theory carries a 0–1 health reading — how much current evidence supports it — and a direction of travel. They are held in tension on purpose. The Observatory's job is to track which way the evidence moves, not to crown a winner.

Two readings per theory: narrated (discretionary, healthΔ-0 discipline) and computed (pinned priors 2026-07-02 × pre-registered likelihood ratios on new evidence, bounds [0.1, 10]). Divergence between them is itself information. Machinery in record.json.

Health readings are estimates, held open to revision. What makes them inspectable is on each theory's page: the assumption it rests on, and the single observation that would move it.
