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

Start with zero-shot with clear instructions. Add few-shot examples only when the instruction logic is ambiguous or the format is highly specific, as few-shot can bias the model negatively.

Journey Context:
The belief is that more examples equal better pattern matching. However, few-shot examples can constrain the model's reasoning, introduce bias from the specific examples chosen, or cause the model to overfit to the style of the examples rather than the underlying task. Modern instruction-tuned models are highly capable of zero-shot execution, and research shows that the label space and format of few-shot examples matter more than the actual semantic content of the examples.
