Plexii glossary
AI hallucination
An AI-generated statement that sounds plausible but is false, unsupported or inconsistent with the available source material.
What it means
Neutral definition: a language model stating something false or unsupported with confidence; why it happens in plain terms (it predicts likely text rather than looking facts up). a university library guide). How to check an answer — sources, quotes, numbers — with a link to check ai answers rather than repeating it.
The term is most useful as a shared description. It does not remove the need to look at the actual task, evidence or constraint in front of you.
A practical example
An answer supplies a convincing publication title that does not exist. Checking the citation before using it catches the error.
Put it into practice
- Name the concrete situation before applying the label. AI hallucination is useful only when it changes a choice, boundary or next action.
- Make the state visible: write the owner, time, source or stopping condition down instead of relying on memory.
- Review what happened. Keep the part that reduced ambiguity and change the part that added ceremony without helping the work.
