On first impressions, one generally assumes that the Extraverts of the world are the talkative socialisers, while the Introverts are quiet listeners.
What I am interested in is situations/cases when that is not the case. Are talkativeness and extraversion necessarily related? Or is perhaps talkativeness affected by another dichotomy other than E/I? Is it possible/normal to have an extravert quieter than an introvert? Is it just a temporary thing? How would one tell the difference? What other factors might come into play?
And so on. Discuss!
