Rational Decision-Making Capacity in End of Life Decision-Making
This chapter brings the rationalist account of decision-making capacity to bear on three case studies. The first concerns a patient who ‘unwisely’ refuses treatment for a condition that can be treated straightforwardly, but which will otherwise be fatal. The second concerns a Jehovah’s Witness who refuses a life-saving blood transfusion. The third concerns an individual suffering from anorexia nervosa, who recognizes that she is dangerously underweight, but who nonetheless refuses to consume food. The author argues that a rationalist approach can accommodate the thought that an individual’s decision-making capacity is not precluded by their making an ‘unwise’ decision. It can also accommodate both the thought that Jehovah’s Witnesses can have decision-making capacity to refuse blood transfusions, and that some sufferers of anorexia nervosa may lack decision-making capacity. The author argues that his account is better equipped to investigate the nuances of these hard cases than the standard account.
