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-SG-2026-022 · Evidence B · P1

In a nonrandomized Chinese study with 481 university students completing follow-up, adding a CPR/AED game-based mobile app to traditional training produced higher 7-day theoretical and practical-skill scores and a 6-month median knowledge score of 9/10 versus 8/10 for traditional training alone.

What this does not establish

Knowledge retention is not retained hands-on competence, real emergency behavior, patient survival or a randomized causal estimate.

Counterevidence & uncertainty

Nonrandom allocation, no preintervention survey for some outcomes and a young highly educated sample limit causal strength and generalizability.

What would change the reading

Update with randomized trials measuring long-term practical competence and real or validated simulated response.
