Model Evaluation Should Focus on Robustness

The author emphasizes that model outputs can only be understood in the context of upstream assumptions like training data, objective functions, benchmarks, and hyperparameter tuning. Truly effective analysis isn't about finding the "best" prompt, but systematically comparing whether results remain stable across different prompts, models, and settings.

They define this approach as "theory-driven benchmarking" and an "epistemological stress test": if a conclusion only holds under a specific prompt, it's likely a prompt-dependent phenomenon rather than a robust finding.
