AI Jargon Buster
AI news and the language around it, simplified.
What is a Hallucination?
A hallucination occurs when an AI system confidently presents false or invented information as if it were factual. Because these systems are designed to predict the next likely word in a sentence rather than check the truth, they can create convincing but entirely incorrect statements. This includes inventing fake news, citing non-existent legal cases, or fabricating historical dates. The AI does not know it is lying because it lacks a concept of truth. It simply follows patterns to build a response that sounds logical and authoritative to the reader, even when the underlying data is completely wrong.
Why this matters to you
Hallucinations pose a significant risk to professional accuracy. If you rely on AI for research, data analysis, or drafting client communications, you must treat every output as a draft that requires human verification. Relying on unverified AI content can damage your professional reputation and lead to costly errors in decision-making or reporting.
How you might hear this
The AI tool provided a very detailed summary of the project, but I had to rewrite it because it hallucinated several budget figures that did not match our actual records.
