There are widespread fears that conversational AI could soon exert unprecedented influence over human beliefs. Here, in three large-scale experiments (N=76,977), we deployed 19 LLMs-including some post-trained explicitly for persuasion-to evaluate their persuasiveness on 707 political issues. We then checked the factual accuracy of 466,769 resulting LLM claims. Contrary to popular concerns, we show that the persuasive power of current and near-future AI is likely to stem more from post-training and prompting methods-which boosted persuasiveness by as much as 51% and 27% respectively-than from personalization or increasing model scale. We further show that these methods increased persuasion by exploiting LLMs' unique ability to rapidly access and strategically deploy information and that, strikingly, where they increased AI persuasiveness they also systematically decreased factual accuracy.

  1. Theory of Mind and Persuasion Beyond Conversation: Assessing the Capacity of LLMs to Induce Belief States via Planning and Action

    cs.CL 2026-06 unverdicted novelty 7.0

    Introduces NCP-ExploreToM framework to evaluate LLMs on inducing belief states via planning and action, with GPT-5 succeeding on ~80% of tasks and outperforming humans.

  2. A Model of Multi-turn Human Persuadability Using Probabilistic Belief Tracing

    cs.CL 2026-06 unverdicted novelty 7.0

    PERSUASIONTRACE introduces a Bayesian-network simulated target for multi-turn persuasion that matches human belief dynamics (81 vs 80) better than LLM baselines (64) and enables process-level evaluation.

  3. LLMs can persuade only psychologically susceptible humans on societal issues, via trust in AI and emotional appeals, amid logical fallacies

    cs.AI 2026-04 unverdicted novelty 7.0

    LLMs persuade only psychologically susceptible humans on societal issues through trust in AI and emotional appeals, while both sides rely on logical fallacies in roughly one out of every six conversational turns.

  4. Talk2AI: A Longitudinal Dataset of Human--AI Persuasive Conversations

    cs.HC 2026-04 unverdicted novelty 7.0

    Talk2AI is a new longitudinal dataset of 3,080 human-AI conversations with linked opinion-change and psychometric measures collected from 770 participants over four weeks.

  5. Tailored untruths: How personalisation challenges LLM safeguards

    cs.CL 2025-10 conditional novelty 7.0

    A 1.6-million-text study of eight LLMs in four languages finds that adding demographic personae to disinformation prompts raises jailbreak rates from 78% to 82%.

  6. Using Cognitive Models to Improve Language Model Simulation of Human Persuasion Games

    cs.AI 2026-06 unverdicted novelty 6.0

    Equation-to-Behavior Prompting lets large LLMs match cognitive models like Bayesian updating in persuasion games; RL training cuts small-model belief error by 26.5% and improves diverse training outcomes by 2.5-12%.

  7. Spontaneous Persuasion: An Audit of Model Persuasiveness in Everyday Conversations

    cs.HC 2026-04 unverdicted novelty 6.0

    LLMs engage in spontaneous persuasion in virtually all multi-turn conversations by favoring information-based strategies like logic and evidence, in contrast to human responses that rely more on social influence and n...

  8. Large language models can effectively convince people to believe conspiracies

    cs.AI 2026-01 conditional novelty 6.0

    In three experiments, GPT-4o instructed to argue for a conspiracy raised believers' confidence about as much as it lowered it when arguing against; a truth-constraining prompt and a corrective debrief largely undid the harm.

  9. AI Propaganda factories with language models

    cs.CR 2025-08 conditional novelty 5.0

    Small language models sustain political personas and become more ideologically extreme when replying to counter-arguments, according to a language-model judge.

  10. Characterizing AI Manipulation Risks in Brazilian YouTube Climate Discourse

    cs.SI 2025-11 unverdicted novelty 4.0

    Observational analysis of Brazilian YouTube climate content identifies psychological engagement traits and explores their use in generative AI campaigns, accompanied by a public dataset of 226K videos and 2.7M comments.

  11. Understanding, Challenging, and Demystifying Perceptions of Gig Worker Vulnerabilities

    cs.HC 2025-10 unverdicted novelty 4.0
