[counterintuitive] few-shot prompting always better than zero-shot

Start with zero-shot prompting; only add few-shot examples if the task requires specific formatting, style, or edge-case handling that the model cannot deduce from instructions alone.

Journey Context:
The consensus is that providing examples \(few-shot\) is strictly superior to zero-shot. However, research shows that few-shot examples can mislead models: they often learn the bias or superficial format of the examples rather than the underlying task. If the examples are slightly out-of-distribution or the task is simple reasoning, few-shot can degrade accuracy compared to zero-shot. Zero-shot forces the model to rely on its pre-trained reasoning capabilities.
