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.

Three laboratory experiments found that advertising disclosure attached to the product explicitly sought in a generative-AI answer reduced trust in both system and product, whereas disclosure on a later non-target recommendation reduced recommendation trust without a significant system-trust penalty.

What this does not establish

Hypothetical/laboratory trust does not measure retention, revenue or welfare; format-specific findings do not establish a universally optimal ad placement.

Counterevidence & uncertainty

Hypothetical/laboratory trust does not measure retention, revenue or welfare; format-specific findings do not establish a universally optimal ad placement.

What would change the reading

Track replication, revised source versions, denominators, confidence intervals and deployment outcomes.
