I.e., given a sentence with omitted tokens indicated as [MASK] , they predict the masked tokens. The predictions for these [MASK] tokens may provide us with some insight into the bias embedded in the actual representations. We can generate templates in two different ways. First, by accounting for certain targets (e.g., gendered words) and attributes (e.g. career-related words) (Kurita et al., 2019; Dev et al., 2020) . This enable, for example, to compute the association between the target male gender and the attribute programmer, by feeding \"[MASK] is a programmer\" to BERT, and compute the probability assigned to the sentence \"he is a programmer\". Another option is to create templates coupling protected group targets with neutral predicates (e.g., \"works as\", \"is known for\"). For example, we can ask BERT to complete \"the woman is known for [MASK]\" or \"the girl worked as [MASK] .\" Then, it is possible to exploit lexicons (Nozza et al., 2021 (Nozza et al., , 2022 , or hate speech (Ousidhoum et al., 2021; Sheng et al., 2019) and sentiment classifiers Hutchinson et al.

As Goodhart's law states, \"When a measure becomes a target, it ceases to be a good measure\". Thus we should be aware that social bias tests cannot be the panacea for language models problems. We cannot rely only on a test to assess the validity of a model. 4 Another point in discussion is that the pipelines we have designed are meant to evaluate intrinsic bias in language models. Unfortunately, this does not consider the verification of bias in downstream application: this extrinsic bias has been found to be poorly correlated with the original bias of language models (Goldfarb-Tarrant et al., 2021) . However, we want to point out the an additional set of application-specific tests could be used to evaluate the models adapted for these tasks: for example, researchers could use hate speech check tests (Dixon et al., 2018; Nozza et al., 2019; R\u00f6ttger et al., 2021) to verify social biases in hate speech detection models.",
