LLMs Exhibit Unique Biases Beyond Human Prejudices
ValerioCapraro · x · 2026-08-28
Research indicates that LLMs display unique biases beyond just reproducing human prejudices:
- Position Bias: When alternatives are similar in quality, models favor the first option. When quality is low, the bias shifts to favoring later options.
- Name Bias: Some models (e.g., Claude 3 Haiku) favor candidates purely based on names, even with constant resumes and positions.
These are not harmless tie-breakers; presentation order can reverse a model's underlying preference. These specific biases have not been documented in human decision-making, suggesting LLMs are not mere mirrors of our biases.
