When Chain-of-Thought Backfires: Evaluating Prompt Sensitivity in Medical Language Models

📰 ArXiv cs.AI

Chain-of-Thought prompting can decrease accuracy in medical language models by 5.7% compared to direct answering

advanced Published 30 Mar 2026
Action Steps
  1. Evaluate the performance of medical language models using Chain-of-Thought prompting on robustness tests
  2. Compare the results to direct answering to identify potential decreases in accuracy
  3. Consider the implications of prompt sensitivity on the reliability of medical language models in real-world applications
  4. Investigate alternative prompting methods to mitigate the negative effects of Chain-of-Thought prompting
Who Needs to Know This

ML researchers and engineers working on medical language models can benefit from understanding the limitations of Chain-of-Thought prompting, as it can inform their design choices and evaluation methodologies

Key Insight

💡 Chain-of-Thought prompting is not always effective and can lead to decreased accuracy in medical language models
