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-AISO-2026-005 · Evidence A · P1

Conditional on searches that triggered an AI Overview, its display reduced outbound organic clicks from 0.62 to 0.37 per search and increased zero-click probability from 0.54 to 0.73.

What this does not establish

Conditional effect is not for all Google traffic; treatment also lifts organic results on screen, and click quality is not conversion or revenue.

Counterevidence & uncertainty

The study found no measurable improvement in active time, bounce, return-to-search or pages per external click.

What would change the reading

Track replication, revised versions, denominators, confidence intervals, platform changes and deployed commercial outcomes.
