LLMs hallucinate / verify AI output with domain expertise
Language models produce plausible language, not guaranteed truth. Because their mistakes can sound convincing, reliable use depends on enough independent domain knowledge to test the output rather than merely recognize a fluent answer.
The more convincing an AI-generated answer sounds, the easier its mistake may be to miss. Fluency can disguise a hallucination so well that a novice accepts precisely what an expert would question.
E1Plausibility outruns truth
A language model generates likely completions; it does not guarantee that the completed claim is correct. That creates an asymmetric problem: producing an answer can be easy for the model, while detecting a subtle error requires knowledge the user may not have. Domain theory supplies the independent expectations, constraints, and checks needed to notice when an apparently coherent answer does not fit reality.
E1Verification cannot be delegated to the same guess
The model can still be useful, but confidence, polish, and internal coherence are not independent verification. If you cannot assess the domain yourself, its output must remain provisional until someone with relevant expertise checks it.
E1Write the test before accepting the answer
For your next AI-assisted task, identify one domain constraint the result must satisfy—an equation, source, rule, expected edge case, or known outcome—and test the output against it. If you cannot name such a check, learn that piece of theory or send the result to someone who can.

"if you haven't become some level of domain expert yourself you will not spot those mistakes... language learning models... they hallucinate... make sure that you understand the theory behind whatever you're using."
