Bias and Justice in Language Models: Evidence from a Linguistically, Socially, and Culturally Asymmetric Literature
Summary
A systematic literature review of 60 studies published between 2020 and 2025 reveals significant biases and gaps in research concerning Large Language Models (LLMs). The review highlights a strong predominance of evaluations conducted in English, a disproportionate focus on gender bias often treated as binary, and a greater emphasis on diagnosing bias rather than implementing mitigation strategies. Key findings also indicate a scarcity of intersectional, multilingual, and real-world use case analyses, pointing to substantial methodological and sociocultural deficiencies within the current academic discourse on LLM fairness and justice. This asymmetry in research priorities raises concerns about the generalizability and applicability of current bias mitigation efforts.
Key takeaway
For research scientists developing or evaluating LLMs, recognizing the current literature's biases is crucial. You should prioritize designing studies that incorporate multilingual datasets, intersectional analyses of discrimination, and real-world usage scenarios to ensure more robust and equitable model development. Shifting focus from mere diagnosis to effective mitigation strategies will lead to more just and globally applicable LLMs.
Key insights
LLM bias research is skewed towards English and binary gender, lacking intersectional and multilingual real-world analyses.
Principles
- Research disproportionately diagnoses bias over mitigating it.
- Bias evaluations are predominantly English-centric.
- Gender bias is often treated as a binary issue.
In practice
- Prioritize multilingual LLM bias evaluation.
- Integrate intersectional bias analysis.
- Focus on real-world LLM use scenarios.
