LLM persuasion evaluations show weak agreement across methods

A new study published on arXiv evaluates the persuasive capabilities of fifteen large language models (LLMs), finding that different evaluation methods yield weakly correlated results. The study adapted nine existing automated methods to a shared setup and discovered that model refusals, particularly on manipulation tasks, significantly reduce agreement between these methods. General capability also plays a role, with rational persuasion methods tracking it while manipulation methods do not, suggesting that a single persuasion score is task-specific and does not reflect a model's overall persuasiveness.

    LLM Persuasion Is in the Eye of the Evaluation

    arXiv:2610.10232v1 Announce Type: new Abstract: Large language models (LLMs) have already been shown to match or exceed human experts in persuasion. While their persuasive capabilities hold promise for beneficial uses such as education and health communication, they can also be u…
