The paper "Medical Causal Hypothesis Verification with Large Language Models" reports a small-scale study evaluating eight LLMs on 17 medical causal hypotheses. The authors introduce an evaluation framework and annotate 1,067 evidence points across six criteria, using nine metrics to assess performance. Results show that while LLMs have strong recall, they frequently fail to provide valid scientific articles, evidence, or reject unsupported hypotheses, revealing a critical limitation for their use in healthcare.

CoBe is a benchmark that evaluates a model’s ability to perform conversational counterfactual text editing, requiring the model to revise a given scenario based on a hypothetical change while preserving unaffected facts. The dataset includes 2,000 questions across domains such as healthcare, science, engineering, business, and everyday life. Experiments show that current models often default to associational generation rather than maintaining causal structure, and performance does not reliably improve with larger model size or longer outputs.

The paper investigates whether large language models (LLMs) truly perform formal causal reasoning by testing them on datasets generated by the CLadder framework. It finds that LLMs and even simple models like random forests can achieve high accuracy on CLadder data, largely due to superficial, highly predictive patterns embedded by the generator. The authors argue that strong performance on CLadder likely reflects exploitation of these patterns rather than genuine causal reasoning, and that many commercial LLMs show brittle results when critical text is removed.
