Nothing is more difficult, and therefore more precious, than to be able to decide.
Napoléon Bonaparte, Maxims (1804-1815)
A physician who is 90 per cent 'certain' about any decision will always seek additional information in the hope that it will increase the 'confidence' with which he makes such a decision. The decision…will be either correct or incorrect, and the outcome is independent of the confidence with which the decision is reached. When additional information cannot possibly alter the decision, but only gives rise to a greater sense of comfort on the part of the physician, such additional information is of no benefit to the patient. Its only benefit is in reducing the discomfort of the physician.
Harold M. Schoolman 1 , 1977
