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-PRO-2026-012 · Evidence A · P1

Selecting a non-discounted meal bundle increased purchases of products outside the bundle by causing shoppers to underestimate total basket size.

What this does not establish

Food and meal bundles, experimental baskets and item counts do not establish revenue, contribution margin, repeat purchase or waste outcomes.

Counterevidence & uncertainty

The basket lift occurred without a price discount, but only when shoppers selected a bundle; merely displaying bundles is not equivalent to universal incremental sales.

What would change the reading

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