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-ALGP-2026-007 · Evidence A · P1

A representative Dutch factorial experiment found that use of private individual data, third-party sharing and higher personalized prices each worsened perceptions of personalized advertising and increased resistance.

What this does not establish

Scenario responses are not observed ad clicks, purchases, churn or revenue and do not isolate AI from non-AI personalization.

Counterevidence & uncertainty

Personalization can increase relevance, but intimate data use and adverse price treatment can overwhelm that benefit in perceived acceptability.

What would change the reading

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