Why AI Hallucinates
AI hallucination is not just random failure. It often comes from the model continuing a pattern without enough grounding.
Fluency Is Not Evidence
Language models are trained to produce plausible text. Plausible text can sound authoritative even when the underlying fact is missing, outdated, or invented.
Gaps Get Filled
When a prompt asks for a complete answer but the model has incomplete information, it may fill gaps instead of stopping. That is useful for drafting and dangerous for verification.
Structure Can Hide Risk
Tables, JSON, citations, and step-by-step lists make answers look more reliable. They improve readability, not truth. A clean structure still needs checking.
Reduce the Risk
Ask for uncertainty, require sources for factual claims, verify high-stakes content, and repair machine-readable formats before putting them into a workflow.
