  "title": "Hide first scores until everyone has one",
  "summary": "A score can become an anchor even when nobody says a word.",
  "kind": "principle",
  "body": "Collect initial ratings privately and reveal the distribution only after the submission window closes. Anonymity can reduce status pressure, but timing matters too: later reviewers should not inherit earlier numbers before forming their own view. Preserve identities separately when accountability requires them.",
  "limits": [
    "For tasks where later reviewers must build on earlier specialized analysis, strict score independence may be less appropriate than staged information sharing."
