First, do no harm… How much of the things we do every day are worthwhile? We all do so many interventions, but are they actually worthwhile?



Some may be ineffective, some inefficient, and some may be harmful. But which is which? How do we find out whether we should, or shouldn’t do something?



What is an acceptable miss rate? What are the implications of getting this trending towards zero? Who will have our backs if something goes wrong, and how defensive should we be?



Benficience, and non malifience. Not two sides of the same coin: they are two ends of a seesaw.
