Why this is here
The triage of 2026-10-29 put it in the File tier for CLAIM-359 and CLAIM-349. Edmondson 1999 (LIT-1220, NOTE-1404) is read: across 51 teams in one company, psychological safety went with learning behaviour, and it says nothing about controls or adversarial members. CLAIM-359’s note says the step from controls that treat dissent as suspect to less learning is the claim’s own inference. This earlier paper is, by the triage’s account and by later citations of it, where Edmondson found that the units with more recorded drug errors were the ones whose climate made errors safe to report, so that a punitive climate shows up as fewer reported errors rather than fewer errors. That is unverified here. If the reading bears it out, it is the nearest observation the record can reach of control suppressing disclosure, the effect A42’s translation in CLAIM-349 predicts (“less disclosure of near misses”).
