Balancing confidence and humility in the diagnostic process.

Humility in medicine can be difficult to achieve, yet arguably is one of the most important competencies to master. Overconfidence, on the contrary, is a natural tendency, having established its roots in evolution where quicker and more confident decisions likely conferred a selective advantage. Moreover, humility may evoke an image of weakness and vulnerability, antithetical to contemporary medicine, whose culture is dominated by overconfidence. Nevertheless, humility can be learned, and is important because overconfident behavior can be detrimental to our patients medically, psychosocially and legally, when it results in delayed or missed diagnoses. To achieve humility requires a great deal of metacognition, normalizing doubt and not being afraid to utilize tools that may feel beneath us. To practice humility requires strength and emotional resilience. In this paper we explore the definitions, roles and implications of humility in medicine, and we pose suggestions of how to accomplish this in the diagnostic process.
