Hmmm, interesting. You clearly explored deeply into this. To clarify, nothing wrong with any of this, they are simple different states of being. I feel a slight advantage in being able to switch, be able to go in and out of both states. Perhaps I'm none anymore. I'm not sure if all extroverts judge people based on what they see on the surface. I feel the defining attribute of extrovert is much smaller fear (or even ignorance) of uncertainty. I feel introverts hate being wrong so much more it becomes painful, so they display a stronger fear (and recognition) of uncertainty in all domains in life.
