Today: the five AI headlines of the day → and the AI Wiki
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-DM-2026-005 · Evidence A · P0

Evaluation planning should begin during intervention design so assignment, comparison groups, data collection and decision timing can preserve the ability to learn.

Counterevidence & uncertainty

Early evaluation planning can still fail if implementation changes silently, power is inadequate, outcomes arrive too late, or organizational incentives suppress negative results.

What would change the reading

Review when treatment logic, rollout, target population or primary outcomes materially change; require a versioned amendment rather than silent protocol drift.
