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-LRO-2026-004 · Evidence B · P1

Roughly 16% of sampled Yelp restaurant reviews were filtered as suspicious; filtering was more likely when reputation was weak, after bad reviews, and under stronger competition.

What this does not establish

Filtered status is not ground truth, and the study does not quantify incremental sales caused by fake reviews, detection accuracy, current Google/Yelp filter performance, or the ROI of reputation software.

Counterevidence & uncertainty

Review systems create measurable demand value yet that value strengthens manipulation incentives; chain restaurants, which benefit less from Yelp, are also less likely to exhibit suspected fraud.

What would change the reading

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