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

Start with zero-shot. Only add few-shot examples if the task is ambiguous, requires a specific format, or zero-shot fails. Ensure few-shot examples are diverse and unbiased.

Journey Context:
Adding examples is standard practice to 'show' the model what to do. However, recent models are heavily instruction-tuned and often perform better zero-shot. Bad few-shot examples can introduce bias, confuse the model if they are too similar, or waste context window. Research shows the format of demonstrations matters more than the actual input-label mapping, meaning misleading examples severely degrade performance.
