I get what you're saying, it's just something that doesn't seem to happen in reality. Can you name such people? I can come up with people like Garry Kasparov or Al Gore, both of them reported to be ENTJs, with measured IQ scores in the 120s - 130s, depending on the test. Those are indeed fairly high, yet I can't name any inventions connected to them. Inventiveness just don't seem to be the gift of extraverted people. Just like intelligence is made up of several factors as well. Both personality and intelligence can be argued forever or said to be forever unclear concepts, it's something that usually happens when individual perception and scientific "objectivity" attempt to merge. If I go by my feelings alone, I can see clearly for myself, but chances are it won't be widely accepted. If I try to put together something that's scientifically acceptable, (my view of) reality might gets corrupted and over-abstracted in the process. That's what I was probing for. Introverted people clearly still have a desire for kinship, only it happens to be harder for them to find mates they can connect with on a deeper level. Or is it intelligent people who end up being lonely? Or are these two things interchangeable? Can an extroverted person whose major trait is to thrive on socialization feel lonely (for any serious amount of time)? I don't think they can. My premise (and that of many other people who researched this) was that intelligent people do end up being lonely most of the time. From then on you can make the connection yourself regarding extraversion. Check out how extraverts and introverts are clearly different in handling and reacting to stimuli: It would be quite hard to mistake an extravert for an introvert when carefully measured and monitored the above way, so while we can paint theoretical characters, some of them will turn out to be unrealistic ones, like the non-socializing extravert you keep proposing. It also kind of puts an end to the now rather popular fad of how certain people like to label themselves as "introverted extravert" or "extraverted introvert".
