a lil bit of both
I think more people are 2 but I also feel a lot are just scarred to be social for whatever reason. From bootleg studies of mine lol I notice when most people online (since this doesn't really come up IRL like that) claim they introverts they usually are lacking in looks, social skills, etc that would make them "popular" for lack of a better term. You don't see the "beautiful" people on this vibe most of the time its always them cats when you see them you like ok.a lil bit of both
