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-LOC-2026-008 · Evidence A · P1

Native-language slogans were perceived as more emotional on average, but the effect reversed for concepts predominantly experienced in the second-language context.

What this does not establish

This measures perceived emotional intensity and originality, not recall, click, conversion, purchase, revenue or sales. Mostly European bilingual convenience samples and word/slogan stimuli do not establish campaign performance; proficiency and lived language context are central moderators.

Counterevidence & uncertainty

The native-language emotional advantage reverses when the concept is predominantly experienced in L2, directly contradicting a universal 'emotion always works better in the mother tongue' rule.

What would change the reading

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