Learning Outcome
Learn why fluent AI output can still be wrong and how to verify it before use.
Core Ideas
- Hallucination: A fluent but unsupported or false model output.
- Grounding: Tying answers to reliable source material.
- Verification: Checking output against trusted evidence.
- Confidence trap: Mistaking polished wording for correctness.
Career Use Case
A student using AI for exam revision can spot when a confident explanation needs checking against a textbook or official syllabus.
Practical Workflow
- Start by naming the outcome: what should improve after using Hallucinations, Confidence and AI Limitations?
- Add the input material, constraints, and success criteria before asking for output.
- Ask for assumptions and uncertainty when the answer affects a real decision.
- Verify important claims, numbers, and policy statements before publishing or acting.
Hands-On Mini Task
- Ask AI for three facts about a topic you know, then mark which claims need source verification before use.
- A good answer separates fluent wording from evidence and names the source used for verification.
- Before moving on, explain how Hallucination and Grounding change the decision.
Common Mistakes
- Using a generic prompt when the task needs clear context.
- Accepting polished wording as proof of accuracy.
- Sharing private data without redaction or approval.
- Skipping a final human review for important decisions.
Quick Revision
Module 1: AI Foundations lesson 3 is about practical judgement: use AI to increase speed, but keep the goal, context, evidence, and accountability clear.
FAQs
Is Hallucinations, Confidence and AI Limitations only for technical users?
No. The course treats AI as a practical workplace and learning skill, with technical depth only where it improves judgement.
Should I trust AI output immediately?
No. Use AI to accelerate work, then verify facts, privacy, source fit, and reasoning before relying on the result.
What should I practice after this lesson?
Ask AI for three facts about a topic you know, then mark which claims need source verification before use.
