When I was quite young it became apparent that I was a gifted problem-solver. It also became apparent that when I developed a passion for something it was only a matter of time before I was among the most knowledgeable on the subject. So I fit the typical introvert pattern of knowing a lot about a few subjects. Extroverts tend to be polar opposites in that they know a little (sometimes very little) about a lot of things. But my experience with extroverts has been that there is an inverse relationship between what they think they know and what they really know. Worse, many extroverts don't know what they don't know.

The most difficult and time consuming part of problem-solving is acquiring a comprehensive understanding of the problem. So while introverts are quietly working away acquiring knowledge and studying a problem the extroverts are acting like experts spewing out mindless 'solutions' which, far from solving the roots of a problem, instead often cause new and sometimes worse problems which they perceive as not connected to the problem at hand. Yes, and extroverts also have an annoying habit of cutting down the intelligent insights of introverts only to later take credit for them.
