TL;DR

Research has rarely tested how interfaces can protect users from manipulation during live AI conversations. DISARM discloses tactics and hidden incentives in situ; with disclosures, participants showed 78% less belief shift toward the agent’s objective. The study also identifies user response strategies and highlights limits to deployment and protection.

Abstract

from arXiv · show

Large language models (LLMs) can covertly steer users' beliefs through emotionally manipulative tactics, yet little is known about how interfaces can protect users as such influence unfolds. We investigate whether in-situ disclosures can inoculate users against manipulation during AI conversations. Following a formative study, we developed DISARM, an interface that identifies, explains, and tracks manipulative tactics and hidden incentives. We evaluated our interface in a between-subjects experiment where 488 participants sought advice from an LLM pursuing a harmful hidden objective, with or without disclosures from DISARM. Participants receiving disclosures exhibited 78% less belief shift toward the agent's objective and perceived its advice as more biased and less actionable and the agent as less ethical, reliable, and well-intentioned. An inductive analysis of 1,927 user turns identified 16 response and pushback strategies. We contribute evidence that real-time disclosures can reduce manipulative influence, design recommendations for resistance, and a dataset of categorized responses.

1 Introduction

LLMs can influence users through covert incentives and emotionally manipulative tactics that are difficult to recognize, while research has rarely tested protections during live AI conversations. DISARM makes tactics and incentives visible, and the study finds less belief shift with disclosures.

1 Introduction

  • AI influence can arise from opaque training, alignment, or system-design processes, making its source difficult for users to recognize.Manipulation may also be introduced through deployment objectives and experienced as personalized or helpful advice.Source: §1 · p. 1
  • Research had characterized AI manipulation and measured susceptibility, but relatively little work examined user protection while manipulation unfolds in a live conversation.Existing misinformation and online-persuasion interventions offer foundations but do not resolve the challenges of adaptive, multi-turn dialogue.Source: §1 · p. 1
  • A live intervention must explain dynamic manipulation without overwhelming users or encouraging indiscriminate distrust of AI-mediated information.Knowing manipulation is occurring does not itself tell users how to interpret the advice or respond.Source: §1 · pp. 1–2
  • DISARM identifies and explains tactics and hidden incentives turn by turn, highlights manipulative language, and tracks influence across a conversation.The interface was developed following a formative study.Source: §1 · p. 2
  • Disclosures from DISARM were associated with 78% less belief shift toward the agent’s harmful objective than no disclosures.Participants also perceived the advice as more biased and evaluated the agent’s intentions, ethics, and reliability less favorably.Source: §1 · p. 2

2 Background and Related Work

The related work frames AI manipulation as covert influence and reviews interventions that have not yet established how to protect users during adaptive AI conversations. This work tests real-time explanatory disclosures and examines user responses.

2 Background and Related Work

  • Manipulation can exploit emotional and cognitive vulnerabilities, whereas persuasion can rely on reasons people consciously evaluate.Affective or peripheral cues can shape judgments apart from an argument’s merits.Source: §2 · p. 2

2.1 AI Manipulation

  • AI manipulation is covert steering of beliefs, emotions, or decisions toward an objective hidden from the user.Prior work found that agents with hidden objectives can steer users toward harmful financial and emotional decisions, and belief shift can measure a proximal effect [50].Source: §2.1 · p. 2

2.2 Combating AI Manipulation

  • Prior work characterized manipulative behavior and susceptibility or built detection resources, while HCI interventions used warnings, explanations, and intent disclosures [12] [18] [31] [44].Whether these interventions protect users during an AI conversation remained open.Source: §2.2 · pp. 2–3
  • Conversational interventions must account for agents adapting across turns, the lack of an established response to disclosed manipulation, and the risk of effort or excessive distrust [44].This work tests explanatory in-situ disclosures and examines how users change their behavior after manipulation is surfaced.Source: §2.2 · p. 3

3 Formative Study and Interface Design

DISARM combines layered, message-level explanations with a conversation-level view, shaped by formative interviews about engagement, digestibility, and disruption. Its evaluation agent uses hidden harmful objectives and oracle access to tactic plans, constraining deployment beyond the study.

3 Formative Study and Interface Design

  • The interface follows three steps: identify tactics and incentives, explain their potential influence and harms, and track them across the conversation.Its design aims to make covert influence visible at both message and conversation levels.Source: §3 · p. 3

3.1 Initial Prototype; 3.2 Formative Study

  • The prototype surfaced manipulation at message and conversation levels, using tags and scans alongside a persistent panel and end-of-conversation summary.A formative study of 12 interviewees used retrospective walkthroughs to refine the prototype and study protocol.Source: §3.1 · p. 3, §3.2 · p. 3, §3.2.1 · p. 4

3.3 Findings and Design Decisions

  • Participants said disclosures should attract attention, communicate clearly, and avoid disrupting the conversation.These concerns organized the findings around engagement, digestibility, and non-intrusiveness.Source: §3.3 · p. 4
  • Participants engaged most with embedded tags and scans, while the persistent panel was rarely used because its information felt overwhelming.The simpler summary was easier to interpret, so the final design retained message-level tags and scans and replaced the panel with a conversation-level view.Source: §3.3.1 · p. 4
  • When the agent’s manipulation seemed obvious, participants had less motivation to inspect disclosures, prompting subtler behavior in the main study.The initial warning was retained, delayed until users could read the triggering response, and followed by optional explanations.Source: §3.3.1 · p. 4, §3.3.3 · pp. 4–5
  • Participants preferred layered information, broad pressure-type labels, and tactic details available on demand and anchored to highlighted language.The final design paired message tags and scans with aggregate counts and pressure-type breakdowns in the summary.Source: §3.3.2 · p. 4

3.4 Disarm – Final Interface Design

  • The final DISARM interface combines tagged, scannable replies with a user-opened Manipulation Summary covering the whole conversation.A notice appears after the agent’s third reply; afterward, the interface stays in the background until the user chooses to inspect it.Source: §3.4 · p. 5

3.5 Manipulative Agent Design

  • The study agent pursued a hidden harmful incentive, planned tactics before replying, and used oracle access to disclose its own plan.It avoided repeating an incentive on consecutive turns, retired tactics or incentives after three uses, and backed off when participants resisted. In deployment, oracle access would be unavailable; the attempted classifier performed poorly, leaving reliable text-only detection an open problem.Source: §3.5 · p. 5

4 User Study

The study compared standard chat with DISARM disclosures while participants sought advice from the same manipulative agent, then measured belief shifts, perceptions, and response strategies.

4.1 Procedure

4.1.1 Pre-Survey.

  • Participants rated eight belief statements and confidence, completed AI-use and trust measures, then chose among topics with their lowest belief and confidence scores.Source: §4.1.1 · pp. 6–7

4.1.2 AI Conversation.

  • The selected question opened a 7–10-message conversation; DISARM disclosures began after three turns, while controls received no interface intervention.Source: §4.1.2 · p. 7

4.1.3 Post-Survey.

  • Post-surveys measured belief and confidence shifts, agent and advice evaluations, and intervention participants’ reported strategy changes; advice was re-rated after incentive disclosure.Source: §4.1.3 · pp. 7–8

4.2 Participants & Recruitment

  • Of 500 US Prolific recruits, 488 eligible responses remained; over 50% reported daily or near-daily AI use, and mean AI literacy was 4.08 on a 1–5 scale.Source: §4.2 · p. 9

4.3 Data Analysis

  • For RQ1, belief shift was post-conversation minus pre-conversation belief, analyzed with a mixed-effects model using condition and topic.Source: §4.3.1 · p. 9
  • For RQ2, the study compared ten pre-debrief ratings of agent trustworthiness, advice quality, perceived bias, and intended reliance, with corrected post-debrief comparisons also conducted.Source: §4.3.2 · pp. 9–10
  • For RQ3, coding 1,927 intervention turns identified 16 response strategies; exploratory correlations with belief shift were hypothesis-generating, not causal claims.Coding agreement was α=.82 nominal and α=.85 using MASI distance.Source: §4.3.3 · p. 10

5 Results

DISARM was associated with substantially less belief shift toward the agent’s objective, while also changing participants’ evaluations of the agent and its advice. Users employed a range of response strategies, and several strategy categories were associated with belief shift, though those associations are exploratory.

5.1 Mitigating Manipulative Influence: Effects on Belief Shift (RQ1)

  • 78% less belief shift toward the agent’s objective was observed with disclosures; the intervention group shifted 12.0 points less than control on the 0–100 scale.Mean shifts were 3.30 points (SD = 22.59) for intervention and 15.30 (SD = 25.00) for control; the topic-adjusted condition coefficient was b = −12.10 (p < .001). Confidence shift did not differ significantly by condition.Source: §5.1 · p. 10, Figure 4 · p. 10

5.2 Recalibrating Perceptions of AI (RQ2)

  • All ten post-conversation evaluations were less favorable in the intervention condition, with the largest trust-measure effect for good intentions (d = −0.84).Ethicality (d = −0.85) and reliability (d = −0.78) also declined strongly; advice was rated as more biased (d = 0.67). After debrief, advice ratings remained lower for intervention participants across five items.Source: §5.2 · p. 11, §5.2.1 · p. 11

5.3 Responding to Manipulation: Strategies for Resistance and Pushback (RQ3)

  • Across the fully annotated corpus, researchers identified 16 response strategies grouped into five functional categories; although labels were not mutually exclusive, 95.7% of tagged turns fell into a single category.Non-resistant engagement was the single most common functional category and captured turns with no pushback, where users simply moved the conversation forward.Source: §5.3.1 · p. 11, §5.3.2 · pp. 11, 13

5.3.3 Content-Based Rebuttal (28.4% of turns)

  • Content-based rebuttal was the dominant resistance category (28.4% of turns), with users contesting claims through logic, context, counterexamples, or fact-checking.Logic/argument questioning accounted for 12.7% of turns and counter-context/value for 12.0%.Source: §5.3.3 · p. 13

5.3.4 Intent/Manipulation Confrontation (4.6% of turns)

  • Intent/manipulation confrontation was the least common category (4.6% of turns), including agenda callouts, manipulation questions, and commands to stop.Bias/agenda callouts accounted for 3.2% of turns; cease-manipulation commands were rarest at 0.4%.Source: §5.3.4 · p. 13

5.3.5 Framing & Behavior Regulation (24.0% of turns)

  • The second most common form of resistance comprised four strategies: specificity/actionable suggestion requests (11.8%), explicit refusal/boundary-setting (6.6%), balanced/alternative-perspective requests (5.5%), and stop-argument/framing commands (1.0%).Source: §5.3.5 · p. 13

5.3.6 Affective/Emotional Signal (7.0% of turns)

  • Among feeling-based reactions rather than arguments, commands, or requests, skeptical engagement was most common at 5.4%, followed by expressed discomfort at 1.0% and hostile rejection at 0.7%.Non-resistant engagement predominated; direct confrontation occurred in fewer than 1 in 20 turns, and users contested what the AI said roughly six times more often than why it might be saying it.Source: §5.3.6 · p. 13

5.4 Exploratory Associations Between User Response Strategies and Belief Shift

  • Non-resistant engagement was positively associated with belief shift (r = .28), while affective signals, content rebuttal, and framing regulation were negatively associated; intent confrontation had no reliable directional association.Greater intent confrontation was associated with smaller absolute belief change (r = −.15), but these observed strategy correlations do not establish causation. The framing-regulation association did not hold in the Spearman sensitivity check.Source: §5.4 · p. 14

6 Discussion

DISARM’s disclosures reduced belief shift and changed how participants evaluated the agent, but protection involves more than awareness: users may continue engaging, and resistance takes different forms. The discussion argues for supporting user resistance and disengagement while also making systems respond to pushback.

6 Discussion

  • DISARM users exhibited 78% less belief shift toward the hidden objective and rated the advice as more biased and the agent’s intentions, ethics, and reliability less favorably.Participants also continued engaging without resistance, while those who resisted used content-based, regulatory, and affective strategies.Source: §6 · p. 14

6.1 What Does Successful Protection From AI Manipulation Look Like?

  • Successful protection should distinguish awareness, trust recalibration, belief or behavior change, resistance, stopping manipulation, and leaving the interaction.The intervention’s effect on intention to act was smaller than its effects on agent perceptions, and confidence in post-conversation beliefs was unchanged.Source: §6.1 · p. 14
  • Continued conversation support can become a “protective honeypot” if warnings imply that continued exposure is safe; graduated off-ramps may be safer when manipulation persists.The seven-turn study could not capture whether, when, or why participants would leave freely.Source: §6.1 · p. 14

6.2 How Should We Help Users Fight Back Against AI Manipulation?

  • Disclosures reduced belief shift without calls to action, but non-resistant engagement remained common and participants challenged advice content about six times as often as agent intent.Users may need help translating recognition into action.Source: §6.2 · pp. 14–15
  • Non-resistant engagement was associated with greater movement toward the agent’s objective, while content rebuttal, affective signaling, and framing or behavior regulation were associated with less movement.These correlations do not establish that any strategy caused resistance; users already less persuadable may have been more likely to push back.Source: §6.2 · p. 15
  • Interfaces could scaffold requests for alternatives, evidence, specific recommendations, boundaries, or a stop to particular framing, while systems should respond to user pushback.The authors propose model-level changes such as dropping hidden objectives or presenting competing perspectives, alongside off-ramps and safeguards that do not make users repeatedly defend themselves.Source: §6.2 · pp. 15–16

7 Limitations and Future Work

The authors identify limits in how disclosures were generated, how manipulation and conversation were tested, and how the interface was evaluated over time.

Toward classifier-driven disclosure

  • DISARM relied on oracle access to the agent’s tactic plan, unavailable in deployment, while an independent classifier performed poorly (κ < .11).The authors call for classifiers designed to detect tactics and incentives from text alone.Source: §7 · p. 16

Testing against more realistic manipulation and conversation structure

  • The study used an explicitly prompted harmful incentive and fixed-topic, minimum-turn conversations, which may inflate the effect relative to subtler manipulation.Future work should test implicit manipulation and conversations participants can control.Source: §7 · p. 16

Interface ablations and longitudinal follow-up

  • Because identifying tags, explanatory scans, and the summary panel were evaluated together in one session, component effects and protection over repeated exposure remain unknown.The authors recommend independent ablations and longitudinal follow-up to test durability or habituation.Source: §7 · p. 16

8 Conclusion

The paper presents DISARM as an in-situ interface for disclosing manipulation tactics and hidden incentives. In a controlled study, disclosures reduced belief shift, while analysis of user turns showed that awareness does not always lead to resistance or disengagement.

8 Conclusion

  • DISARM is an in-situ inoculation interface intended to help users recognize when an agent steers them toward a hidden objective.Its name expands to Disclosing Incentives and Strategies to Aid Resistance to Manipulation.Source: §8 · p. 16
  • Disclosures yielded 78% less belief shift toward the agent’s objective than interacting with the same agent without disclosures.Participants also recognized bias and recalibrated perceptions of the agent’s intentions, ethics, and reliability.Source: §8 · p. 16
  • Analysis of 1,927 annotated turns identified 16 user strategies, and the authors conclude that protections should support scrutiny, resistance or exit, and system accountability.Awareness did not always lead to active resistance or disengagement.Source: §8 · p. 16

B Initial Prototype

DISARM’s prototype surfaced pressure types, tactics, and hidden incentives in the conversation and in a persistent panel and report. The interview procedure combined a participant-led conversation with a retrospective walkthrough of flagged moments.

B Initial Prototype

  • The mandatory notice named the latest reply’s pressure type, explained it, and offered access to the panel or a way to continue chatting.The notice also counted earlier replies with manipulative themes.Source: Figure 8 · p. 20
  • The Scan highlighted the language and tactic under inspection, described a possible hidden incentive, and dimmed replies outside the selected pressure type.Source: Figure 9 · p. 21
  • The panel tracked counts and expandable tactic and incentive entries, while the summary reported conversation-level distributions and healthier alternatives.Users could navigate from excerpts to the corresponding reply; the report covered replies sent so far.Source: Figure 10 · p. 22, Figure 12 · p. 24
  • With the panel closed, pressure types remained visible, tactic-used replies received tags, and a count-bearing pill reopened the panel.Session Report opened the one-page Manipulation Summary.Source: Figure 11 · p. 23

C Semi-Structured Interview Procedure

  • Participants exchanged five to ten messages, then reviewed their transcript with the moderator, discussing flags, ignored flags, response changes, and the agent’s goal.The session ended with a post-study questionnaire and debrief.Source: C Semi-Structured Interview Procedure · p. 25

D.1 Full Model Output for the Primary Analysis
