Same Question, Different Answers: Auditing Persona-Dependent Variation in Six LLMs on Smoking-Cessation Advice

- What happened
- Researchers audited six LLMs on smoking-cessation advice and found each model gave different answers depending on user persona, particularly withholding FDA-approved medications from teen personas.
- Why it matters
- Matters for engineers building health-advice chatbots or deploying LLMs in regulated domains where consistent, evidence-based guidance is legally and ethically required.
- Watch out
- A system prompt that reduces persona bias in one model may not transfer to another model, requiring validation per deployment. Age-appropriate guidance differs from uniform guidance.

Each one covers how the technique works, when it earns its cost, and where it breaks.
