Times have not changed that much. In effect, the public mind tends to expect certain diagnoses popularized by the media, and the professional mind delivers them. These forerunners, or precursors, contribute to the perpetuation of iatrogenic disease in health care. Not infrequently, patients come to their doctors suspecting they have a particular condition. The doctor then either confirms or denies that suspicion.
Language is the currency of exchange.
Let us now consider the doctor's voice. It is common knowledge that the human voice is not a solitary entity, but rather a reflection and expression of someone's character, temperament, personality, and emotional disposition. The unsure doctor's voice, for instance, might be somewhat halting, tentative, or quavering, while the confident doctor's voice is strong, steady, controlled, and calming. Any treatment rendered should factor in the impact a doctor's voice has on a patient. While these observations lack the exactitude of pure science, they do warrant some probationary attention.
