Health professions education commonly treats ethics competence as something that can be secured through curricular coverage, professional standards, case analysis, and assessment of appropriate responses. These approaches are necessary, but they can also create an educational problem when learners discover that success depends more reliably on displaying the expected answer than on exposing uncertainty, articulating competing reasons, or questioning the institutional conditions under which decisions are made. This article develops a Mechanism-Based Educational Theory of ethical judgment development to explain why compliance-oriented environments may produce competent rule performance without necessarily cultivating the capacity for justified ethical judgment. The account distinguishes moral uncertainty from simple knowledge deficiency and treats reason-giving as an educational practice through which learners make judgments available for challenge, revision, and accountability. Ethical judgment is therefore conceptualized as developmental and relational: learners must recognize morally salient uncertainty, articulate and compare reasons, respond to criticism, revise conclusions when warranted, and understand how authority and responsibility are distributed across clinical and educational settings. The model further proposes that supervision, assessment, hidden curricula, hierarchy, and institutional reward structures can strengthen, interrupt, or reverse this development. Compliance is not rejected; some rules and constraints are ethically indispensable. The problem arises when observable conformity becomes a surrogate for judgment in situations where interpretation, contestability, and responsibility remain morally consequential. The resulting account provides a basis for designing curricula and assessment systems that preserve standards while making reasoned ethical judgment educationally visible.
