Abstract

Performance evaluation systems increasingly incorporate artificial intelligence, yet employee acceptance remains limited. This experimental study examined how explanation quality and evaluator type influenced fairness perceptions and trust in AI-based performance evaluations among 275 U.S. working adults. Using a 2 × 2 vignette design, results demonstrated that explanation quality produced large effects on perceived fairness (d = 1.79) and trust, while evaluator type—human versus AI—had negligible independent effects (d = −0.08) when explanations were high quality. Fairness mediated the explanation-trust relationship (indirect effect = 1.95, 95% CI [1.65, 2.26]), with inconsistent mediation indicated by a negative direct effect (b = −0.81, p < .001) when fairness was controlled. Findings suggest organizations should prioritize explanation quality over evaluator source when implementing AI evaluation systems.
