In our healthcare system, parents normally make medical decisions for their kids because, we think, children are not competent to make such decisions for themselves. Similarly, we permit doctors to violate or defer consent for mentally incompetent adults. But where do we draw the line for what constitutes ‘incompetence’? Should severely depressed patients, for example, have the right to decide for themselves whether or not they want treatment? What makes a patient so incompetent, they should be precluded from making their own decisions?
