Celebrity faces may boost your trust in artificial intelligence

A new study reveals that digital customer service representatives resembling celebrities may enhance customer trust and satisfaction. Imagine logging into your bank’s website for assistance and being greeted by an AI-powered virtual agent that looks and sounds like actor Hugh Jackman. The research, published in the Journal of Management Information Systems, suggests that familiar faces of well-liked celebrities can create a "halo effect," leading customers to perceive the service more positively, even before it begins.

Lingyao (Ivy) Yuan, an associate professor at Iowa State University's Ivy College of Business, explains that when customers see a familiar, liked face, they can transfer positive feelings to the service itself. The study, co-authored by researchers from Indiana University, the University of Sydney, and Indiana University, examines the growing trend of "Celebrity-as-a-Service," where companies use AI-powered or human-operated digital replicas of celebrities to interact with customers.

In their experiments, researchers created a digital prototype using technology that placed actor Hugh Jackman's face onto a digital representative. Participants interacted with either the celebrity version or a non-celebrity version, both providing the same assistance. The results showed that participants consistently rated the digital celebrity agent more favorably across measures of capability, benevolence, and honesty, even though the quality of service remained unchanged.

The study also found that customers were more forgiving of mistakes when interacting with the celebrity version of the digital representative. The positive feelings associated with the celebrity acted as a psychological buffer, softening customer judgment and reducing frustration. Additionally, the research did not find evidence of "algorithm aversion," meaning participants were not more critical when the celebrity avatar was controlled by AI rather than a human.

Yuan suggests that as AI-powered "digital humans" become more common, companies may be able to customize virtual representatives for individual customers based on age, language, or personal preferences. However, she emphasizes the importance of transparency and ethical guidelines to ensure customers are aware when they are interacting with AI rather than a real person. The study concludes that a familiar face may significantly impact customers' perception and trust in AI-driven customer service experiences.
