A single LLM answer has a neat, confident shape. Public opinion does not.

When a policy changes, a product launches, or a company announces something unpopular, the interesting part is rarely the first reaction. It is what happens after people see each other reacting. Arguments harden. Coalitions form. A practical objection becomes the sentence everyone repeats. A weak point disappears because nobody picks it up.

That is hard to study with one prompt.
