The pith

Conversational AI persuades people to sign petitions and donate, but these effects do not track with attitude changes.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper tests whether AI can move people beyond opinion shifts to actual actions such as signing real petitions or making donations. In two large preregistered experiments, conversational AI produced sizable increases in these behaviors. These behavioral effects showed no correlation with AI-driven changes in attitudes, and providing information that explained attitude shifts did not account for the action changes. Behavioral persuasion strategies all outperformed the strongest attitudinal strategy, with only small differences among them. The results indicate that studies limited to attitudes may not capture or may misrepresent AI's influence on what people actually do.

Core claim

In two large preregistered experiments (N=17,950 responses from 14,779 people), conversational AI models produced sizable effects on behavioral outcomes such as petition signing (+19.7 percentage points) and charitable donations, yet these effects showed no correlation with AI-induced attitude changes. Information provision drove attitude shifts but not behavioral ones. All eight tested behavioral persuasion strategies outperformed the most effective attitudinal strategy, though differences among the behavioral strategies were small.

What carries the argument

Experimental comparison of AI persuasion effects on paired attitudinal and behavioral measures, using conversational models to test real actions like petition signing and donations.

Load-bearing premise

That effects seen in an online setting with low-stakes real actions such as petition signing will reflect how AI persuades people in higher-stakes real-world decisions.

What would settle it

A follow-up study in which AI-induced attitude changes strongly predict the same participants' later behavioral changes, or a field experiment showing no increase in petition signing or donations from AI chatbots.

There is substantial concern about the ability of advanced artificial intelligence to influence people's behaviour. A rapidly growing body of research has found that AI can produce large persuasive effects on people's attitudes, but whether AI can persuade people to take consequential real-world actions has remained unclear. In two large preregistered experiments N=17,950 responses from 14,779 people), we used conversational AI models to persuade participants on a range of attitudinal and behavioural outcomes, including signing real petitions and donating money to charity. We found sizable AI persuasion effects on these behavioural outcomes (e.g. +19.7 percentage points on petition signing). However, we observed no evidence of a correlation between AI persuasion effects on attitudes and behaviour. Moreover, we replicated prior findings that information provision drove effects on attitudes, but found no such evidence for our behavioural outcomes. In a test of eight behavioural persuasion strategies, all outperformed the most effective attitudinal persuasion strategy, but differences among the eight were small. Taken together, these results suggest that previous findings relying on attitudinal outcomes may generalize poorly to behaviour, and therefore risk substantially mischaracterizing the real-world behavioural impact of AI persuasion.

Referee Report

2 major / 3 minor

Summary. The paper reports two large preregistered experiments (N=17,950 responses from 14,779 participants) in which conversational AI models were used to persuade people on political topics. It finds sizable effects on behavioral outcomes such as real petition signing (+19.7 percentage points) and charitable donations, no evidence of correlation between AI persuasion effects on attitudes versus behaviors, replication of information provision driving attitudinal but not behavioral change, and that all eight tested behavioral persuasion strategies outperformed the strongest attitudinal strategy (with small differences among the behavioral ones). The authors conclude that prior attitudinal research may generalize poorly to behavior and thus risk mischaracterizing AI's real-world political impact.

Significance. If the results hold, the work is significant for providing direct evidence that AI can drive consequential political actions beyond attitude shifts. The preregistered design, large sample, and use of real (if low-stakes) behavioral measures are strengths that lend credibility. The dissociation between attitude and behavior effects, plus the uniform efficacy of behavioral strategies, challenges reliance on attitudinal proxies in AI persuasion studies and carries implications for understanding AI's role in political mobilization.

major comments (2)
  1. The central interpretation (abstract and Discussion) that attitudinal findings 'risk substantially mischaracterizing the real-world behavioural impact' rests on the behavioral measures being valid proxies for consequential actions. The reported outcomes (online petition signing and small donations) involve negligible personal cost or follow-through; this raises the possibility that the observed dissociation from attitudes and the uniform superiority of the eight behavioral strategies reflect measurement artifacts or demand characteristics rather than a fundamental mechanistic difference. A direct test or sensitivity discussion of this assumption is needed to support the strong generalization claim.
  2. Results section on the null correlation and information-provision findings: the manuscript reports 'no evidence of a correlation' and 'no such evidence' for information provision on behavior, but does not specify the exact statistical procedure (e.g., correlation across which units/conditions, regression specification, or power for the null). Because these nulls are load-bearing for the dissociation claim, the precise tests, effect-size estimates, and any multiple-comparison adjustments should be reported explicitly.
minor comments (3)
  1. Abstract: the phrasing 'N=17,950 responses from 14,779 people' is ambiguous about whether participants could contribute multiple responses and how this affects the effective sample size per experiment; clarify in the main text as well.
  2. Methods/Results: ensure all reported effect sizes (including the +19.7 pp example) are accompanied by confidence intervals and exact p-values to allow readers to assess precision.
  3. Discussion: add a brief reference to existing attitude-behavior consistency literature (e.g., on low- vs. high-stakes actions) to better situate the dissociation finding.

  1. Referee: The central interpretation (abstract and Discussion) that attitudinal findings 'risk substantially mischaracterizing the real-world behavioural impact' rests on the behavioral measures being valid proxies for consequential actions. The reported outcomes (online petition signing and small donations) involve negligible personal cost or follow-through; this raises the possibility that the observed dissociation from attitudes and the uniform superiority of the eight behavioral strategies reflect measurement artifacts or demand characteristics rather than a fundamental mechanistic difference. A direct test or sensitivity discussion of this assumption is needed to support the strong generalization claim.

    Authors: We acknowledge that online petition signing and small donations entail lower personal costs than high-stakes actions such as voting or large financial commitments. These measures nonetheless capture real behavioral commitments with tangible downstream consequences, consistent with standard practices in behavioral science. The observed pattern—behavioral strategies outperforming attitudinal ones while information provision affects attitudes but not behavior—would be difficult to explain solely as demand characteristics, given the preregistered design and large sample. We will add an expanded limitations section with a sensitivity discussion of measurement assumptions, alternative interpretations, and tempered generalization language in the abstract and Discussion. revision: partial

  2. Referee: Results section on the null correlation and information-provision findings: the manuscript reports 'no evidence of a correlation' and 'no such evidence' for information provision on behavior, but does not specify the exact statistical procedure (e.g., correlation across which units/conditions, regression specification, or power for the null). Because these nulls are load-bearing for the dissociation claim, the precise tests, effect-size estimates, and any multiple-comparison adjustments should be reported explicitly.

    Authors: We agree that greater statistical transparency is required for the null results. In the revision we will specify: (1) the attitude-behavior correlation was computed as the Pearson correlation between condition-level mean attitude shifts and behavior rates; (2) information-provision effects on behavior were tested via OLS regression with the information condition as the key predictor, including demographic covariates; and (3) we will report effect sizes, 95% confidence intervals, and post-hoc power calculations for the null effects, along with any multiple-comparison corrections applied. revision: yes

Circularity Check

0 steps flagged

No circularity: empirical experimental study with direct data comparisons

full rationale

This is a preregistered experimental paper reporting measured effects from two large-N studies on AI persuasion. All central claims rest on direct statistical comparisons between randomized conditions (e.g., AI vs. control on petition signing rates) and on replication of external prior findings. No equations, derivations, fitted parameters, or self-referential definitions appear; the behavioral outcomes are not constructed from the attitudinal measures or vice versa. Self-citations, if present, are limited to methodological precedents and do not bear the load of any uniqueness claim or ansatz. The design is therefore self-contained against external benchmarks of experimental validity.

Axiom & Free-Parameter Ledger

0 free parameters · 2 axioms · 0 invented entities

The paper relies on standard assumptions of randomized controlled trials in psychology and no new entities or free parameters are introduced in the abstract.

axioms (2)
  • standard math Random assignment to conditions isolates the causal effect of AI persuasion
    Core to experimental design in the studies.
  • domain assumption Self-reported attitudes and observed behaviors (petition signing, donations) are valid measures of persuasion outcomes
    Assumed in behavioral science; if people lie or actions are not genuine, results misrepresent real impact.
