As a long-term patient in a burns unit, Dan Ariely frequently had to endure the painful process of having his bandages removed. Already endowed with a highly inquisitive mind, he conducted research on ways of making the process less painful, and proudly presented his findings to the nurses. However, he observed that even when the nurses were presented with clear evidence that they could reduce the pain felt by patients during bandage removal, they continued to administer the more familiar – and more painful – method. As Ariely says in
Predictably irrational: The hidden forces that shape our decisions, his epiphany came when he realised that if nurses, who have an interest in helping and caring for patients, manage to misunderstand what constitutes reality for their patients, perhaps other people similarly misunderstand the consequences of their behaviours.
