You can make this argument about most software developers too, while they may create unique applications, they are mainly using the "already known" (existing languages, API's, etc)... You can then go on to apply this argument to nearly any other "white collar" job, accounting is "the application of the already known", etc.. White collar does not mean that you are in a research field and pushing the limits of knowledg…
"Blue collar" was a poor voice of words. You're right that the white/blue collar divide is not a creative difference. But I still feel that software development is a creative field whereas most of medicine is reactive. All fields are based upon past knowledge so the use of APIs seems irrelevant since they are just tools used to create. The criterion to differentiate between creative and non-creative fields seems to b…
However, sometimes--probably most of the time--the patient's presentation is so unclear (e.g. "I just feel weird. . . ."), there are so many variables to juggle in your head at once (twenty different lab values, the way the liver feels, the imaging findings, the color of the patient's sclera, the smell of their breath, their mood) that things become far too complex for any flowchart. These are the times when you need creativity, "book smarts" and perhaps above all, "emotional intelligence" to be a good doctor. There are plenty of doctors lacking one or more of these elements, and they just aren't very good at the job.
