(extrovert here who hates meetings)
I think the extro/introvert split is unhelpful, people have preferences for and against different social activities. E.g. I can enjoy parties but not meetings, or prefer to read in silence but work as part of a group. The article is trying to take a few examples and extrapolate a much wider theory out of them.
A fun article by Alan Jacobs. Check out the paper he cites, if anyone finds an non-paywalled version, I'll edit in the link here. HT for the link to Michael Bloom.
I really do need to find more written by this author. But while I certainly do very much share this sentiment I have a hard time figuring out how common it is. After all people don't look good saying they "don't like meeting new people".
