Persona prompting research challenges simple prompt-engineering advice
Research on expert personas argues that prompt technique evaluation is harder than simple social-media advice suggests.
• Prompting guidance should be tested against real tasks, not accepted as a slogan.
• Benchmark limitations can hide whether a technique helps or fails.
• Teams need evaluation infrastructure before standardizing prompt patterns.
Builder take
• Treat prompt libraries like software: version them, test them, and document when each pattern should be used.
