Researchers have introduced BenchMIRT, a novel methodology designed to dissect the performance of large language models (LLMs) on benchmarks by analyzing individual prompts. This approach, inspired by Item Response Theory (IRT), aims to disentangle the various underlying capabilities, such as safety and general reasoning, that contribute to a model's score on a given task. By applying multidimensional IRT (MIRT) to data from 100 LLMs across 16 benchmarks, BenchMIRT revealed that some benchmarks, like BBQ, which are intended to measure social bias, are more closely aligned with general reasoning abilities than previously understood.
