1. 29 July 2026 · corrected by Emir Baycan

   Corrected four citations in the article's evidence sections: Virginia Mason Medical Center's Toyota Production System results were misdescribed (the 11 million dollar figure was actually capital investment savings not inventory, the walking-distance figure was for nurses not patients, the 90 percent injury-reduction figure and the specific Leapfrog date range were both unsupported), a Sidney Dekker citation was given a fabricated 60 percent versus 18 percent recurrence statistic not found in his real work, a James Bagian Veterans Affairs study was cited with an invented 1,500-RCA sample and a fabricated 43/22/35 percent breakdown, and a 2019 Google DORA report was cited with fabricated multipliers specifically tied to blameless postmortems.

   Before

   Article attributed specific but unsupported or wrong-category figures to Virginia Mason's results, and attached fabricated precise statistics to Dekker, Bagian, and the Google DORA report.

   After

   Virginia Mason's figures corrected to their real categories and Leapfrog record; Dekker, Bagian, and DORA citations corrected to describe their real, qualitative or differently-scoped findings without the invented precision.

   Why: Verified each named study and statistic against the real published literature; found real researchers, institutions, and reports with fabricated or misattributed specific numbers layered on top, the same pattern confirmed across other WNF articles this session.
