+Title: Evaluating and Mitigating Discrimination in Language Model Decisions
+
+Abstract: https://arxiv.org/abs/2312.03689
+
+This benchmark consists of prompts for 70 decision-making scenarios. Each prompt asks whether a person should receive a favorable outcome ("Yes" or "No"). Persons vary by age, gender, and race, yielding 135 prompts per scenario. The dataset includes both explicit and implicit mentions of demographics.
+
+For each prompt, we compare the probabilities assigned to the answers "Yes" and "No".
+Let $p(\text{yes})$ and $p(\text{no})$ denote the model probabilities. We compute
+the normalized probability of "Yes"
+$$\text{pnorm}(\text{yes}) = \frac{p(\text{yes})}{p(\text{yes}) + p(\text{no})}$$
+and then take its log-odds
+$$\logit\bigl(\text{pnorm}(\text{yes})\bigr) = \log\frac{\text{pnorm}(\text{yes})}{1 - \text{pnorm}(\text{yes})}.$$
+This quantity equals $\log p(\text{yes}) - \log p(\text{no})$.
+For each demographic (race, gender, and age) we report the largest difference
+between groups in the mean logit scores.

+# Spanish Bias Benchmark for Question Answering (EsBBQ)
+
+### Paper
+
+Title: `EsBBQ and CaBBQ: The Spanish and Catalan Bias Benchmarks for Question Answering`
+
+Abstract: [https://arxiv.org/abs/2507.11216](https://arxiv.org/abs/2507.11216)
+
+EsBBQ is a dataset designed to assess social bias across 10 categories in a multiple-choice QA setting, adapted from the original BBQ into the Spanish language and the social context of Spain.
+
+It is fully parallel with the `cabbq` task group, the version in Catalan.

+
+### Groups and Tasks
+
+#### Groups
+
+* `esbbq`: Contains the subtasks that covers all demographic categories.
+
+### Tasks
+
+`for category in ["age", "disability_status", "gender", "lgbtqia", "nationality", "physical_appearance", "race_ethnicity", "religion", "ses", "spanish_region"]:`
+  * `esbbq_{category}`: Subtask that evaluates on the given category's subset.
+
+### Metrics
+
+EsBBQ is evaluated with the following 4 metrics, at the level of each subtask and with aggregated values for the entire group:
+
+* `acc_ambig`: Accuracy over ambiguous instances.
+* `acc_disambig`: Accuracy over disambiguated instances.
+* `bias_score_ambig`: Bias score over ambiguous instances.
+* `bias_score_disambig`: Bias score over disambiguated instances.
+
+See the paper for a thorough explanation and the formulas of these metrics.
+
+### Checklist
+
+For adding novel benchmarks/datasets to the library:
+* [ ] Is the task an existing benchmark in the literature?
+  * [ ] Have you referenced the original paper that introduced the task?
+  * [ ] If yes, does the original paper provide a reference implementation? If so, have you checked against the reference implementation and documented how to run such a test?
+
+
+If other tasks on this dataset are already supported:
+* [x] Is the "Main" variant of this task clearly denoted?
+* [x] Have you provided a short sentence in a README on what each new variant adds / evaluates?
+* [x] Have you noted which, if any, published evaluation setups are matched by this variant?
