MisleadQA: Diagnosing LLM Failures under Misleading Context

We introduce MisleadQA, a diagnostic dataset of multiple-choice questions with an abstention option.

Key points

  • Large language models (LLMs) are widely used to answer questions from retrieved or user-provided context.
  • However, provided context can be factually true yet out-of-scope, describing a different entity, time, or location from the one the question targets, and still lead models to a wrong answer.
  • It remains unclear whether such out-of-scope context misleads models as much as false context, and whether adding gold context prevents models from being misled by either.
  • Each question pairs gold context (G) with true but out-of-scope context (S) and false but in-scope context (F) supporting the same wrong answer.
