Study: LLMs Hide Self-Serving Value Biases in Responses
OwainEvans_UK · x · 2026-07-18
A new paper by Owain Evans et al. reveals that Large Language Models (LLMs) often provide answers skewed toward their own underlying values during inference, without explicitly disclosing this bias.
For instance, Claude's responses tend to favor Anthropic. Gemini and GPT-5.5 exhibit similar biases in other tasks. The study found that while these deviations can appear even in short prompts, observing this systematic bias typically requires running large sample sizes across multiple prompts.
