Interesting that you bring up Marshall & Warren - in my opinion the truly interesting part of that story is their fight for truth above dogma.

I think you want that in a doctor - a capacity and preparedness to fight the system when it is wrong, unfair, of hurting your patient. Is that a creative skill? I don't know but I doubt it's born out of conformity.

Incidentally I know Dr Marshall, he's an academic at my medical school. He actually paid me to teach him and his team Ruby.
