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-PKSO-2026-005 · Evidence A · P1

Four interpretive front labels each reduced calories in hypothetical beverage and snack selections relative to calorie-only labels, with similar effects across education groups despite differing attention and trust reactions.

What this does not establish

Choices were hypothetical and limited to one beverage plus snack; the experiment does not prove purchase, consumption, persistence, stigma-free implementation or effects beyond U.S. packaged snack contexts.

Counterevidence & uncertainty

Green endorsement labels changed choice despite eliciting less attention and trust than warning or activity labels, so stated label favorability did not rank behavioral effects cleanly.

What would change the reading

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