The first time I heard the mandate that every health professional commits to was in my first experimental psychology class, in the words of the much-loved and missed Professor Ramón Bayés. “Primum non nocere,” he said with the solemnity of the most sacred. First, do no harm. In my youthful naivety, I thought this ethical principle was indelibly etched in everyone who dedicated themselves to psychology and medicine. Later, unfortunately, I have found that this is not the case.
