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-CUX-2026-012 · Evidence A · P1

Among 75,914 new ecommerce visitors, requesting registration before browsing increased registrations by 58.08% but left 24-hour purchase statistically unchanged; among users induced to register, instrumental-variable estimates over 47 days indicated higher purchase probability, order count and revenue.

What this does not establish

Long-run estimates are LATEs for compliers induced to register, not intention-to-treat effects for all visitors; they rely on the exclusion restriction and cookie-based follow-up. The study does not quantify refund, churn, privacy harm or transfer to forced registration at checkout.

Counterevidence & uncertainty

The prompt sharply increased registrations while producing no immediate purchase lift; the positive long-run estimates apply only to induced registrants, not the full randomized population.

What would change the reading

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