The authors define specification overfitting as improving a proxy metric while harming task performance or another specification, and survey how research papers evaluate this risk. They review 74 selected papers, finding that 61 report a main-task correctness measure, but only two combine multiple specification measures with deeper task-performance analysis. These counts describe reporting practice, not demonstrated harm.
