Lesson 4.1
AI failures can look identical on the surface — a wrong, incomplete, or misleading answer. But the underlying cause differs, and so does the strategy for catching it. Click each card to flip it over.
Why this matters. Different failure modes ask for different verification strategies. Hallucination calls for source-checking. Weak patterns call for testing on edge cases. Drift calls for re-evaluating on current data. Bias calls for performance comparisons across groups. "Just don\u2019t trust AI" is too blunt — knowing which failure to look for is the actual skill.
