For us introverts it's the opposite. Being around people drains us of energy. Even if we enjoy their company and enjoy social interaction. It's tiring.
There's probably no silver bullet for office design. People are different, as you say.
I would bet that introverts are _over represented_ in tech, but of course they put us all in open office plans.
Want to work alone? Close door.
Want to work alone but be aware of things going on? Leave the door open.
Can't stand working alone? Go to the open area.
But the low-grade sadists that rise to positions of authority in U.S. corporations will punish the people that don't go to the open area. It's not about what you produce, it's about how much torture you're willing to self-inflict.
Could it be about social dynamics? It's like caching. When you're thinking about whom to give an opportunity to, are you going to think of the friendly person that you see every day, or to that guy you've heard of once who's always in his office and might be a myth?
Although I will admit it is hard to start my side project after work and is probably due to being drained.
