Fairness cues reorganize responsibility beyond system capability in social mixed-ability human–automation interaction
摘要
Automation increasingly augments human performance, creating mixed-ability settings where people using different automated systems differ in performance capability, raising questions about how social fairness, defined here as whether people use the same or different systems, shapes the sense of responsibility for the outcomes of one’s actions. We conducted two experiments using a continuous drawing task where an automated system operated under either auto-correction (improving accuracy) or delay (impairing control). When participants acted alone (Experiment 1), the manipulation of the automated system’s performance capability worked as intended, with auto-correction enhancing the sense of agency, subjective performance, drawing speed, and accuracy, whereas responsibility ratings were unaffected by system capability. In Experiment 2, participants performed the same task while aware of another person using either the same or a different system, introducing a social context that changed responsibility judgments. Participants felt most responsible when both agents used the same system rather than different systems, regardless of actual performance differences. Trial-level analyses showed that this fairness effect was not explained by performance-related variations. Together, the findings indicate that social fairness cues can influence responsibility judgments beyond people’s own performance evaluations in human–automation interaction, motivating further research on fairness-aware design of collaborative technologies.
