A new study published on arXiv investigates language-of-study bias in natural language processing (NLP) peer reviews. Researchers found that papers focusing on non-English languages face significantly higher rates of negative bias compared to English-only papers. The study introduced a dataset called LOBSTER and an LLM-based detection pipeline, achieving an 87.37 macro F1 score in identifying this bias. The most prevalent form of negative bias identified was the demand for unjustified cross-lingual generalization. AI
