Automation Bias and Human Overreliance: Why Human Oversight Can Fail
Automation bias and human overreliance examine why people can place too much trust in automated recommendations, scores, alerts, rankings, predictions, or AI-generated outputs. This article introduces automation bias as the tendency to favor automated output over contrary evidence, and overreliance as dependence that exceeds a system’s validated reliability, scope, or uncertainty. It explains commission errors, omission errors, automation complacency, trust calibration, algorithm aversion, human-in-the-loop limits, interface framing, explanation design, alert fatigue, override friction, appeal pathways, accountability gaps, and contestability. The article shows why human oversight can become symbolic when reviewers lack time, context, authority, training, or incentives to challenge a system. By connecting human factors with algorithmic governance, it frames responsible automation as a process requiring calibrated trust, uncertainty display, meaningful review, override logging, appeal mechanisms, monitoring, and accountable human judgment in high-stakes institutional workflows and public decision systems.
