Study title: AI Advertising-to-Service Inference: When AI Disclosure Triggers Inferences from Ad Production to Process Expectation

Two experiments in service contexts found that disclosing an advertisement as AI-generated reduced the service quality consumers expected. In the first experiment, disclosure also lowered purchase intention. The study was published in the Journal of Advertising in September 2026.

Read the study abstract

As artificial intelligence (AI) disclosure becomes platform-integrated, companies increasingly face “AI-generated” labels in advertising. Prior research has focused on ad-level responses, leaving open whether such cues transfer across touchpoints to shape expectations about the advertised offering. This research proposes an ad-to-service transfer mechanism whereby AI disclosure triggers two countervailing inferences: AI Advertising-to-Service Inference (AISI), a process inference reflecting the belief that firms…

The problem

In two experiments in service contexts, telling consumers an ad was AI-generated lowered the service quality they expected, and in the first experiment it also cut purchase intention.

In brief

The authors attribute the drop to a process inference they call AI Advertising-to-Service Inference: consumers assume a firm that uses AI in its ads also uses AI to deliver its service. Mediation analyses showed this pathway was negative.

A second inference worked in the opposite direction. Perceived Brand AI Expertise, the belief that a firm has the knowledge, experience and infrastructure to deploy AI well, produced a positive, offsetting effect. The authors say this reconciles earlier mixed findings on AI disclosure.

The second experiment tested what happens when website information confirms or violates the expected AI role in service delivery. The authors advise firms under mandatory AI labeling to pair AI-generated ads with credible signals of AI expertise and to clarify AI's role in service delivery, or risk lower quality expectations and purchase intention outweighing production-cost savings.

Main points

  1. The research comprised two experiments set in service contexts.
  2. AI disclosure reduced expected service quality in both experiments.
  3. Purchase intention fell with AI disclosure in Study 1.
  4. A negative indirect pathway ran through AI Advertising-to-Service Inference, the belief that AI is also used in service delivery.
  5. A positive, offsetting effect ran through Perceived Brand AI Expertise.
  6. Study 2 examined website information that confirms or violates the expected AI integration in service delivery.
  7. The authors recommend pairing AI-generated ads with credible AI-expertise signals and clarifying AI's role in service.

The full story

The paper starts from the spread of platform-integrated AI disclosure, which means companies increasingly face 'AI-generated' labels on advertising. Earlier work focused on ad-level responses and left open whether such cues shape expectations about the advertised offering.

The authors propose an ad-to-service transfer mechanism. AI disclosure triggers two competing inferences: a process inference (AISI) that the firm also uses AI in service delivery, and a capability inference (BAIE) that the firm has the expertise to deploy AI effectively across operations.

Both experiments found lower expected service quality after disclosure, and Study 1 also found lower purchase intention. Mediation analyses showed a negative indirect path via AISI and a positive offsetting path via BAIE.

Study 2 varied whether website information confirmed or violated the expected AI integration in service delivery, to see how AISI affects consumer evaluations. The authors conclude that firms should signal AI expertise and clarify AI's role in service, or lower expectations may outweigh production-cost savings.
