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-EBRO-2026-009 · Evidence A · P1

Performance-contingent referral rewards induced high-ability participants to refer higher-performing contacts, whereas larger fixed referral payments did not improve referral quality; high-ability referrers possessed useful private information but used it selectively when incentives aligned.

What this does not establish

This is a laboratory-style casual-work experiment, not an employer's production workforce; it does not establish hiring, retention, demographic equity, or the effect of ordinary employee-referral bonuses when job performance is multidimensional or delayed.

Counterevidence & uncertainty

More money as a fixed finder's fee did not solve the screening problem; reward contingency and referrer ability, not bonus size alone, determined informational value.

What would change the reading

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