I recall seeing opposite advice regarding extraverts and introverts on some TV show about dinner parties a long time ago. They suggested alternating them when arranging a table - the extroverts should be close enough to talk, but they have to talk around introverts. Introverts would have the opportunity to fluidly join conversations going on around them and have an easier time disengaging because someone else beside them will fill in the gap. Obviously, this would be miserable for an extreme introverts, but you can put those people in a corner.

Again, this is a half remembered piece of information, but it stuck with me because it seems to make sense.
