What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-CPCO-2026-011 · Evidence A · P1

What this does not establish

Prior donors to one US political nonprofit are not representative of first-time donors, humanitarian charities, membership programs or countries with different tax and political contexts.

Counterevidence & uncertainty

The existence of a match mattered, while a larger match did not; fundraising claims that higher ratios automatically yield more response were not supported.

What would change the reading

Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial, civic or human outcomes.
