AI视频处理降低信任感，但不影响识谎能力
Through the Looking-Glass: AI-Mediated Video Communication Reduces Interpersonal Trust and Confidence in Judgments
- 用AI修图、换背景或虚拟形象处理视频
- 观众信任度和判断自信下降，但识谎准确率不变
- 适合关注人机交互信任的从业者参考
基于AI的视频通信工具可能影响人们对可信度与可靠性评估。在两项预注册在线实验（共2000名参与者）中，我们考察了AI视频美颜、背景替换及虚拟形象对人际信任、识谎能力及判断自信的影响。参与者观看不同AI中介程度的说话者真假陈述短片。结果发现，使用AI处理的视频中，信任感知和判断自信显著下降，尤其在部分人使用虚拟形象而他人未使用的情况下。然而，实际判断准确率未受影响，且参与者并未更倾向于怀疑使用AI工具者说谎。研究结果表明，AI中介不会削弱识谎能力，也挑战了以线索为基础的识谎理论。强调在重视真实性的场景中，建立可信赖的AI中介工具至关重要。
原文摘要 · Abstract (English)
AI-based tools that mediate, enhance or generate parts of video communication may interfere with how people evaluate trustworthiness and credibility. In two preregistered online experiments (N = 2,000), we examined whether AI-mediated video retouching, background replacement and avatars affect interpersonal trust, people's ability to detect lies and confidence in their judgments. Participants watched short videos of speakers making truthful or deceptive statements across three conditions with varying levels of AI mediation. We observed that perceived trust and confidence in judgments declined in AI-mediated videos, particularly in settings in which some participants used avatars while others did not. However, participants' actual judgment accuracy remained unchanged, and they were no more inclined to suspect those using AI tools of lying. Our findings provide evidence against concerns that AI mediation undermines people's ability to distinguish truth from lies, and against cue-based accounts of lie detection more generally. They highlight the importance of trustworthy AI mediation tools in contexts where not only truth, but also trust and confidence matter.
