Pretty fascinating. And as you said, a high IQ does not necessarily mean a success any more than a PHD makes someone a great doctor. Intelligence is definitely an important factor, because unless you happen to be an inventor or very creative person, I'd wager most successful people have an above average IQ.

But being able to have a bedside manner makes a doctor far more valuable than solely knowledge.

You're a very knowledgeable person and it's clear through your interactions that you know how to converse with people in a direct approach that is respectful and intelligent, but not confrontational or out of control in any way. (We all have our limits, but everything you have wrote about here is extremely good advice to take note of and put into practice).
