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-MB-2026-003 · Evidence A · P1

GeoLift implements power analysis, market selection and synthetic-control inference for aggregated geo experiments; its example outputs are simulated demonstrations, not evidence that any real campaign generated the displayed lift.

Counterevidence & uncertainty

Spillovers, mobility, concurrent campaigns, weak pre-period fit and low market counts can invalidate inference; repository examples are not deployment outcomes.

What would change the reading

Update with independent validation studies or method changes.
