Learn how to evaluate the interpretability and faithfulness of chain-of-thought reasoning in language models under knowledge conflict and why it matters for trustworthy AI decisions

advanced Published 28 May 2026
Action Steps
  1. Test the introspective faithfulness of your language model using the introduced framework
  2. Evaluate the stability of chain-of-thought reasoning across different prompt conditions
  3. Analyze the model's decision-making mechanism when faced with contradictory knowledge
  4. Apply the findings to improve the trustworthiness of language model decisions
  5. Compare the results across different models and datasets to identify trends and patterns

Title: Do Models Know Why They Changed Their Mind? Interpretability and Faithfulness of Chain-of-Thought Under Knowledge Conflict

Abstract:
arXiv:2605.27773v1 Announce Type: cross Abstract: When a language model sees a document contradicting its training knowledge, it must choose: follow the document or trust itself. Prior work proved this choice depends on how well-known the fact is. We ask: does the model's chain-of-thought (CoT) reasoning faithfully report this mechanism? We introduce introspective faithfulness and test it across 200 questions, 8 models, and 4 prompt conditions. We find CoT reasoning is highly stable across oppos
