How to Spot and Reduce Hallucinations (Topic 2) in Module 2 – Use-AI-Safely-Effectively (BG)

How to Spot and Reduce Hallucinations

Hallucination is when an AI produces something that sounds plausible but is false, unsupported, or invented. This is not a rare edge case. It is a normal model failure mode.

Common warning signs

  • unusually specific facts without evidence
  • citations or references you did not provide and cannot verify
  • absolute certainty in a complex topic
  • answers that feel smooth but do not match your domain knowledge

Better habits

Ask the model to separate facts from assumptions. Request a concise answer first, then ask: Which parts of this answer should I verify independently?

Use cross-checking intentionally

For important tasks, compare the output against original source material, an approved document, or another reliable source. The goal is not to distrust everything equally. The goal is to verify the pieces that matter before you act on them.

Never confuse fluency with truth

AI systems are optimized to produce probable language, not guaranteed truth. Polished writing is not evidence.
