TO ERR IS HUMAN—EXCEPT WHEN ONE IS A PHYSICIAN? A Reflection on Fallibility, Blame, and Responsibility in the Practice of Medicine

“To err is human” expresses a basic truth about human judgment: even competent, conscientious, and experienced people remain vulnerable to uncertainty, incomplete information, cognitive limitations, fatigue, and unforeseen outcomes. Yet when an adverse outcome occurs in medicine, the tolerance usually extended to human fallibility often narrows dramatically. This essay argues that recognizing physicians’ fallibility does not diminish professional responsibility, but makes its assessment more ethically coherent. Adverse outcomes, complications, errors, negligence, and responsibility are not interchangeable concepts. Fair accountability requires reconstruction of the information and circumstances available at the time of the clinical decision, attention to systemic as well as individual contributors, and a causal link between a culpable departure from an appropriate standard of care and the harm that followed. The essay also examines hindsight bias, defensive medicine, disclosure, apology, and the need for a just culture in health care. Medicine should neither excuse preventable harm in the name of humanity nor impose an impossible duty of infallibility.
