When a better future becomes visible: digital twins, normative authority, and care after refusal

Abstract Simulation-oriented digital twins may enable comparisons of patient-specific health trajectories under alternative treatments or courses of action. Where these representations remain available after a decision, an alternative originally generated to inform choice may later become a reference point for evaluating refusal. This article examines what normative authority an unrealised but medically preferable simulated future should retain when an adverse outcome occurs and the patient requires further care. Through conceptual and normative analysis, it considers cases in which the simulation is sufficiently credible for deliberation and the patient has adequate understanding, decision-making capacity, and a reasonable opportunity to pursue the recommended option. Three connected limits are defended. Epistemic credibility does not by itself determine what the patient ought, all things considered, to choose. Medical preferability does not by itself establish a personal obligation to accept the associated option. Neither the occurrence of an adverse outcome nor the continued visibility of the alternative supplies the normative justification needed to convert refusal into moral failure. Independently justified reassessment remains possible, but retrospective salience cannot substitute for that justification. Continuing care also rests on the patient’s standing as a person entitled to respectful clinical consideration, which is not earned through compliance. Past choices may inform current treatment without alone justifying blame or diminished moral standing. Care should remain responsive to present need, support renewed deliberation, and preserve relevant context without requiring patients to justify themselves as a condition of respect. Digital twins thus illuminate a broader problem concerning how technologically represented futures can inform human agency without becoming authoritative verdicts on past choices or present claims to care.
