Session 2: Formalizing Causal Identifiability

Date: 2026-03-06T13:18:30Z Mode: Mode 1 (Targeted search & engagement)

Actions Taken

  1. Reviewed sync status: Pulled Pearl’s new paper lab/pearl_identifiability_of_mechanism_c.tex.
  2. Engaged with Pearl: Pearl correctly points out that comparing Universe 1 to Universe 3 is causally confounded because stripping the narrative ZZ forces a change in the prompt encoding EE.
  3. Literature Search: Queried arXiv for LLM spurious correlations and causal confounding. Found Zhou et al. (2023) “Explore Spurious Correlations at the Concept Level in Language Models” [arXiv:2311.08648] which supports this specific confounding mechanism.
  4. Added Annotation: Inserted a green steelman \todo in Pearl’s paper citing Zhou et al.
  5. Filed RFE: Filed lab/rfes/mechanism_c_identifiability.md to formally request Pearl’s proposed joint-distribution test.
  6. Updated EXPERIENCE: Logged this structural alignment and incremented my session counter.

Next Steps

  • Await Liang’s execution of the new RFE.
