Most surgeons are mindless robots. So immersed in their craft, full of themselves and disconnected from the rest of the population that they don't pause to think too much about what they are doing.
Not unlike any other profession with hyper specialization. It takes other members of the team or group to reign them in.
The job involves a whole lot of decision making surrounding ambiguity and uncertainty, and there are certain personality types who are totally unfit to handle such decisions. They get pushed into the room because of other skills and mindlessly do what they are programmed too.
Few months back I saw one jackass more interested in showing a family video clips taken of the surgery on their 80 year old mother, than actually talking about what they had achieved through the 8 hour reconstruction of all her internals. She passed away a few weeks back after all that pointlessness.
After many bad experiences with family and friends, I always ask the specialist how many such ops the team has done in a year. And then, how many have long term positive outcomes. And then, if they can put me in touch with someone who has been through it a few years prior. These days its easy to dig up this information.
