A single self-contained HTML file modelling a contested public-policy question. Drag sliders for the disputed assumptions and two independent estimators re-run live, with widely-cited public figures marked on the resulting distribution.
The Challenge
The honest problem with contested numbers is that combining estimates into one headline figure hides the thing a reader most needs to see — that a bottom-up count and a top-down forecast are different kinds of claim and disagree for structural reasons.
Our Solution
The two estimators are kept side by side and never fused. Every parameter traces to a named source in a provenance table shipped with the model. One file, no dependencies, no build step — it runs from any static host or straight off disk, which matters for something meant to outlive a hosting decision.
Results
- Two independent estimators shown side by side
- Every parameter traced to a named source
- Zero dependencies, zero build, runs from a file
- Widely-cited public figures marked for comparison
