[counterintuitive] Should I always add few-shot examples to my prompt

Start with zero-shot with clear instructions; only add few-shot examples if the model fails to follow the format or logic, as bad or overly specific examples can drastically degrade performance.

Journey Context:
The belief is that few-shot examples teach the model the task better. However, modern instruction-tuned models are heavily optimized for zero-shot instruction following. Few-shot examples can bias the model, restrict its reasoning to the specific patterns of the examples, or introduce errors if the examples are slightly off-target. Research shows the label space and format of examples matter more than the actual content of the examples.
