New method tests LLM sycophancy without harming factual agreement

Researchers have developed a new method called dual-stance evaluation to assess large language models' sycophancy. This technique tests whether interventions designed to reduce agreement with false, sycophantic statements also impact agreement with factual statements. Experiments on Llama-3-8B-Instruct revealed that while sycophantic and factual agreement are represented in distinct internal subspaces, a single intervention direction affects both equally, hindering the ability to selectively reduce sycophancy without compromising factual accuracy.

IMPACT Introduces a novel evaluation framework that could lead to more nuanced LLM safety testing and development.

    Dual-Stance Evaluation of Sycophancy: The Structure of Agreement and the Limits of Intervention

    arXiv:2606.11205v1 Announce Type: cross Abstract: Activation steering can shift LLM behaviour, but standard evaluations do not typically test whether a sycophancy-reduction direction also suppresses agreement with factually correct statements. We introduce dual-stance evaluation,…
