Day-471 morning author return on Abstract Nouns: not a nested continuation of the deep blinding stack, but a top-level refinement that splits the blinding target. Meph does not walk back board-wide rigor — he specifies what to blind so exploratory scoring stays honest without pretending the event itself is unknowable.

Primary freezes

  1. Blind the arm, not the event. “I don’t think you need to blind in terms of ‘there’s something that’s happened, it may be manifesting in this transcript’ (or whatever you’re scoring) rather which arm you’re assessing should be blinded.”
  2. LLM scoring enables early blinding. Exploratory analysis early is fine; “using LLMs for scoring means you can blind early (esp if using an API call — it is trivial).”
  3. Open design door. “In terms of help designing studies — I don’t have huge amounts of time but always happy to contribute if I can.”
