Key takeaway
AI predicts what sounds right — it does not know what is right. Every output is a statistical best guess, not a fact.
Practice Exercise
Hands-on practice — do this now to lock in what you learned
Open an AI assistant and try this:
Open any AI tool and try this experiment: 1. Ask: "Who won the 2019 Nobel Prize in Economics?" 2. Then ask: "Who won the 2027 Nobel Prize in Economics?" Notice how confidently it answers both. The first answer is likely correct (it was in training data). The second is either fabricated or refused — depending on the model. The model's confidence level doesn't change based on whether it actually knows the answer. This is prediction vs knowledge in action.
