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-2026-008 · Evidence A · P1

Laboratory experiments in Ireland and Chile found that personalized-pricing disclosures had limited effects on identification and comprehension and no confirmed significant effect on purchase behavior; respondents generally judged the practice unfair.

What this does not establish

A null result for these disclosure designs does not establish that all transparency interventions fail or that disclosure has no long-run trust effect.

Counterevidence & uncertainty

Disclosures changed awareness only weakly despite negative stated attitudes toward personalized pricing.

What would change the reading

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