> Rather than extroversion being about whether a person is socially "energized" by groups or not, it's really about how much stimulus a person can accept before their brain starts feeling saturated. That's a nice idea, but I'd like to tweak it a bit. It's about the amount of stimulus you prefer. So, yes, as you indicated, introverts tend to have a difficult time with a lot of it. But what you didn't mention is that extroverts tend to have a difficult time if they don't get enough. Indeed, for just about anyone, there is "not enough", and there is "too much".
