Five realistic examples you’ll run into

These are the kinds of outputs that often look convincing—until you try to verify the details.

  • Fabricated sources: The text includes “references,” but they don’t exist or don’t support the claim.
  • Wrong numbers: Dates, percentages, or measurements are stated with confidence but fail basic cross-checks.
  • Overgeneral conclusions: It gives a broad statement that sounds true, but the underlying evidence is missing.
  • Confusing mixed topics: Facts from multiple areas get blended into one story.
  • Unclear uncertainty: The text sounds definitive when it should be probabilistic or conditional.
