This is a well-designed randomized control study that asks the question: Does an LLM's ability to diagnose and manage the same medical scenarios degrade when a patient is the communicator versus a physician. The result: 60% drop in diagnostic accuracy, 12% drop in appropriate management decisions The answer essentially confirms the following suspicions: 1. LLMs are suggestible, naive, and sycophantic 2. Medical literacy drives output; less literacy, less accurate LLM outputs 3. Prompting still confounds frontier models' medical accuracy It is not safe to have people trust LLM medical advice when they're incapable of detecting their own bias and inaccuracies.
