- "If all you have is a hammer, everything looks like a nail" - One issue with hyper specialisation is that sometimes this leads to automatic decision making and following simple protocols and ideas without thinking or questioning them. --- Highly specialized health care professionals have developed their own versions of the “if all you have is a hammer, everything looks like a nail” problem. Interventional cardiologists have gotten so used to treating chest pain with stents—metal tubes that pry open blood vessels—that they do so reflexively even in cases where voluminous research has proven that they are inappropriate or dangerous. A recent study found that cardiac patients were actually less likely to die if they were admitted during a national cardiology meeting, when thousands of cardiologists were away; the researchers suggested it could be because common treatments of dubious effect were less likely to be performed. - David Epstein in [[Range]]
