A phrase that sounds right
In an imaginary dialogue, an assistant says, “A museum has a purple dinosaur found on the moon.” It does not tell us if it is true. This statement is not valid in this example.
A generative AI can produce a response that seems plausible but contains false information. This is often called a hallucination. This word describes a wrong result: it does not mean that the program dreams like a person.
Your mission as a detective
Begin by isolating the fact to be controlled. Where would this dinosaur have been found? Then ask the exact source. A link with a serious title is not enough: open the page and see if it exists and if it actually confirms the sentence.
For a discovery, look for the site of the museum or the study of researchers. Compare the name, the date and what was actually observed. An illustrative photo alone does not prove that the event took place.
If the source is missing or does not confirm the fact, say “I don’t know yet”. It’s better than repeating an unverified answer. You can ask an adult for help in understanding a difficult source.
For a story, it’s different.
Inventing a purple dinosaur is fine if you ask for a tale and everyone knows it’s imaginary. The problem begins when an invention is presented as a real discovery. The instruction and the verification therefore each have their role.
