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-2026-007 · Evidence A · P1

English print advertising improved ad attitude in Ecuador but was statistically equivalent to Spanish and code-switching in Chile and Mexico, despite favorable English-speaker stereotypes in all three countries.

What this does not establish

The endpoint is ad attitude, not comprehension, recall, click, conversion, purchase, revenue or sales. Bilingual higher-education samples, one fictitious product and code-switch placement in a slogan limit transfer to general populations or other formats.

Counterevidence & uncertainty

English-speaker stereotypes were more favorable across all countries, yet an English persuasion advantage appeared only in Ecuador; stereotype valence did not produce a universal outcome.

What would change the reading

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