arXiv:2606.17506v1 Announce Type: new Abstract: Evaluations of social bias in LLMs largely focus on whether models generate or imply biased content. However, as LLMs are increasingly used as judges of bias, they may exhibit social biases in subtler ways in how they evaluate biased content, which current methods do not systematically capture. We call this second-order bias: social bias in an LLM's judgment about social bias, which we evaluate through a novel, philosophically grounded reasoning task. Drawing on entitlement epistemology, we conceptualize bias as misplaced foundational knowledge t
As LLMs become more integrated into critical decision-making and content moderation, the evaluation of their inherent biases, beyond simple content generation, is increasingly pressing.
Understanding second-order bias in LLMs is crucial for ensuring fairness, trustworthiness, and ethical deployment of AI systems, particularly as they take on roles as arbiters of truth and social norms.
The focus of AI ethics research shifts from primarily identifying first-order content bias to also rigorously evaluating how LLMs judge and propagate biases themselves, impacting their design and deployment.

New metrics and methodologies for evaluating LLM bias will emerge, leading to more robust ethical AI standards.
AI development pipelines will need to incorporate 'second-order bias' testing, increasing development complexity and cost.
Public trust in AI systems that cannot demonstrate fairness in judgment will decrease, potentially leading to regulatory pushback and market segmentation based on ethical performance.
