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-AMPO-2026-012 · Evidence B · P1

Human–AI teams produced substantially more ads and better copy, but worse images, less diversity and no significant live-platform outcome lift.

What this does not establish

Crowd teams, no solo-human arm, one think-tank context and GPT-4o period; do not infer brand revenue or general campaign lift. The current arXiv abstract reports 11,024 ads while the detailed March 2026 manuscript body reports 11,138; the body value is used here.

Counterevidence & uncertainty

Productivity and text gains were offset by weaker images and no detected market outcome improvement.

What would change the reading

Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
