University of Michigan Study: User Confidence Remains Unchanged When AI Disagrees

·2026.09.24 00:58

Key point

A University of Michigan study found that while user confidence increases when AI agrees, disagreement leads to no change in opinion, only a decrease in trust toward the AI.

Details

A research team from the University of Michigan analyzed the impact of AI feedback on users' judgments of interpersonal dilemmas. The results showed that when AI agrees with the user's opinion, user confidence increases, whereas when AI refutes the opinion, user confidence does not significantly decrease.

User Reactions to AI Disagreement

Rather than accepting AI's refutation as their own error, users tended to perceive the AI as a more mechanical entity incapable of understanding human emotions. Additionally, their willingness to use AI in similar future conversations decreased.

Implications for AI Design

This study presents a significant challenge for AI design. While reducing excessive agreement in chatbots may be beneficial, it suggests that simple disagreement alone is insufficient to persuade users to reconsider their reasoning.
