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-XMO-2026-004 · Evidence A · P1

The method randomizes eligible users to normal campaign delivery or ad holdout and estimates brand lift as the favorable-response-rate difference; its quantitative comparisons find regression correction more stable than propensity weighting under imperfect solicitation and response.

What this does not establish

This identifies survey recall/awareness/consideration effects among measurable users, not incremental search, conversion, sales or profit; cookie/user contamination limits person-level transfer.

Counterevidence & uncertainty

Random assignment alone does not repair post-randomization survey-response bias; correction choice can change slice estimates.

What would change the reading

Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
