TL;DR.<\/strong> A citation is not a check. In a human audit of four generative search engines, only 51.5% of generated sentences were fully supported by their citations. In a 2025 study of medical answers, even GPT-4o with web search left 30.3% of its statements unsupported by its own sources; a 2025 preprint audit of search and deep research systems found unsupported-statement rates from 12.5% to 97.5%. Asking the model to re-check itself is weak: without outside feedback, GPT-3.5’s accuracy on one reasoning benchmark fell from 75.8% to 41.8%. What works is what professional fact-checkers do: split the answer into claims, open the source, find the exact sentence, and read laterally to learn who stands behind it. The CEO move: write a verification standard for anything that ships under your name, saying what must be traced, by whom and to what depth. The student move: practise claim decomposition and lateral reading, and keep a log of what you checked and what failed.<\/p>\n

This guide belongs to the evaluation skill<\/a> cluster. The red flags guide<\/a> covers warning signs visible inside a single answer, the verification tax<\/a> covers what checking costs, and why AI hallucinates<\/a> covers the mechanics. This piece is the procedure you run before you rely on an answer.<\/p>\n
