Summary

A preregistered experiment with 1,586 people found explained political-bias warnings reduced persuasion in some contexts, but the effect faded within a week.

Participants completed two decisions with a language model biased against their political views. Warnings that explicitly identified political bias and explained it reduced persuasion, but the effect varied by context and did not persist one week later. User characteristics were more consistent predictors: in this sample, Republicans and more frequent AI users were more persuaded, while people reporting greater AI knowledge were less persuaded. The paper argues against treating a generic notice as a complete safeguard. Its findings describe this experiment and should not be generalized to every political setting or user population.
