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-ELO-2026-008 · Evidence A · P1

Varying the subject line across weekly lifecycle emails produced small detected-open gains: 1.1 percentage points across weeks 2-3 among active/new learners and 0.3 points among all new learners; the fixed-effects meta-analysis estimated +0.7 points, while course progress was null.

What this does not establish

Detected opens are not clicks, learning, conversion, revenue or retention. Study 2 eligibility selected initially active learners, and both field tests came from one unnamed MOOC provider over only three weeks.

Counterevidence & uncertainty

A statistically detectable open-rate gain coexisted with a null substantive progress outcome and materially smaller effects in the broader population.

What would change the reading

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