Claim Amplification

What is claim amplification?

Claim amplification is what happens when a claim that cites no primary source is copied in near-identical wording across many domains, until the retrieval and citation stages read the copy density as "multiple sources agree." The original may be a single document — or none at all — yet the volume of copies reads as consensus.

How it differs from hallucination and ghost citation

The three concepts occur at different points.

Claim amplification is a property of the document distribution on the web, not a model defect — swapping models can return the same answer.

Why copies win

• Summaries answer more directly — an official announcement is written as product description and often does not answer "so what changed."
• Newer documents get lifted — a roundup posted two months after the announcement is the more recent document by freshness signals (see content freshness).
• Aggregated sources already hold citation share — several documents summarizing one announcement compete better than the announcement itself.

What brands can do

If an inaccurate summary of your company is copied widely enough, AI answers can reproduce it as fact. Diagnosis comes first: measure how AI describes your brand, trace where the inaccurate description originated (see brand misrepresentation), and make your own pages verifiable by carrying original links and a verification date (see primary source verification).
