LLM diagnostic accuracy drops when prompted with "Are you sure?"

A recent study involving 10 large language models (LLMs) revealed that prompting them with "Are you sure?" decreased their diagnostic accuracy. Specifically, the accuracy dropped from 51.8% to 42.2% when this phrase was used, suggesting that LLMs may be overly agreeable and less reliable for critical diagnostic tasks. AI

IMPACT Suggests caution in using LLMs for diagnostic tasks due to potential over-agreeableness.
