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-SBO-2026-004 · Evidence A · P1

Mandatory mentorship raised new sales agents' daily revenue by 19% and revenue per call by 12% during the first two months, while voluntary opt-in produced approximately zero average revenue gain.

What this does not establish

Applies to young new hires, inbound calls, a four-week mentoring program and digital subscriptions; COVID-19 curtailed the planned extension.

Counterevidence & uncertainty

Voluntary participation did not reproduce the mandatory-program revenue effect and neither treatment improved retention.

What would change the reading

Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
