In this study, we take a closer look at how Winograd schema challenges can be used to evaluate common sense reasoning in LLMs.Specifically, we evaluate generative models of different sizes on the popular WinoGrande benchmark.We release WinoWhat, a new corpus, in which each instance of the WinoGrande validation set is paraphrased.Additionally, we evaluate the performance on the challenge across five common sense knowledge categories, giving more fine-grained insights on what types of knowledge are more challenging for LLMs.Surprisingly, all models perform significantly worse on WinoWhat, implying that LLM reasoning capabilities are overestimated on Wino-Grande.To verify whether this is an effect of benchmark memorization, we match benchmark instances to LLM training data and create two test-suites.We observe that memorization has a minimal effect on model performance on WinoGrande.
