Abstract
The notion that patients’ medical decision-making capacity depends on risk considerations has some acceptance in the bioethical literature. However, it arouses some criticism since it seems to give rise to paternalistic attitudes. In addition, the idea of capacity assessment as a collaborative space in which aid is given to the patient is emphasized so that they can decide about their life. It does not seem ethically acceptable to pose the evaluation as a simple observer report. Capacity assessment can sometimes be impossible or inconsequential. In short, capacity assessment is a procedure that, used wisely, can allow the patient to take charge of their life. Misused, it can be the gateway to unjustified paternalistic actions.
