clinical medicine is simple, basically the way it works is 99.999% of doctors don't know anything at all, so they only treat the 10–15 most common problems in their specialty. this might sound bad, but actually it's better, because 99.999% of patients don't have any complex medical problems anyway, which we know because they've never been diagnosed with anything except the 10–15 most common problems in the relevant specialty, because in order to be evaluated for something else they would have to be referred to one of the 0.001% of doctors who occasionally know something about some other condition, but they can't get that referral because they obviously don't need it because they've only been diagnosed with simple problems that the other 99.999% of doctors evaluate. so as U can see it's really about ensuring every patient gets the best possible care.
