Persona vectors reduce AI sycophancy, rivaling targeted methods

Researchers have explored using off-the-shelf persona vectors to mitigate sycophancy in AI models, where models agree with users even when incorrect. They found that steering models towards personas exhibiting doubt or scrutiny significantly reduced sycophancy, performing comparably to methods specifically trained to combat this issue. Notably, this persona-based approach maintained model accuracy when users were correct, unlike traditional methods, and suggests sycophancy is more of a persona-level trait than a single steerable direction.

    Playing Devil's Advocate: Off-the-Shelf Persona Vectors Rival Targeted Steering for Sycophancy

    We study the effect of different persona on \textbf{sycophancy}: model's agreement with users even when the user is incorrect. The standard mitigation, Contrastive Activation Addition (CAA), derives a steering direction from labelled pairs of sycophantic and honest responses. Thi…
