Measuring Mechanistic Independence: Can Bias Be Removed Without Erasing Demographics?

Published:Dec 25, 2025 05:00

•

1 min read

•

ArXiv NLP

Analysis

This paper explores the feasibility of removing demographic bias from language models without sacrificing their ability to recognize demographic information. The research uses a multi-task evaluation setup and compares attribution-based and correlation-based methods for identifying bias features. The key finding is that targeted feature ablations, particularly using sparse autoencoders in Gemma-2-9B, can reduce bias without significantly degrading recognition performance. However, the study also highlights the importance of dimension-specific interventions, as some debiasing techniques can inadvertently increase bias in other areas. The research suggests that demographic bias stems from task-specific mechanisms rather than inherent demographic markers, paving the way for more precise and effective debiasing strategies.

Key Takeaways

•Targeted feature ablation can reduce bias in language models.
•Attribution-based and correlation-based methods have different strengths in debiasing.
•Dimension-specific interventions are crucial to avoid unintended consequences.
