I certainly agree with you - and it makes me sick.

It's one thing for a "professional" to not keep up on the latest technology. That's the nature of the beast in any evolving field of study. You get so focussed on doing well with what you've already learned that you lose focus on continually learning more. Most engineers and scientists, myself included, are guilty of that.

But to consciously avoid learning more and using that knowledge because you are afraid it will make you look bad....that's dispicable and is anything but the mark of a professional. I've had to tell customers that an approach I was using turned out to be bad or, at the very least, worse and an alternative I've just learned about.

And for a doctor to continue a practice that is harmful, or at the very least not as helpful, to their patients as the information that that doctor possesses seems a fundamental violation of the Hippocratric Oath - and at some point would seem to be a criminal violation of trust.
