\"You are an expert\" prompts can backfire, lowering AI accuracy

Prompts that tell large language models \"you are an expert\" can reduce accuracy, a study found. A University of Southern California team tested six AI models with short and detailed expert-persona instructions. Complex expert prompts slightly improved writing and reasoning on MT-Bench but reduced quality in coding, math and humanities, and lowered overall performance on MMLU. Researchers said the instruction may divert resources from recalling facts. Results also showed gains in blocking unethical content on JailbreakBench.
