There are probably YouTube creators of every Socionic type; however, I've noticed that people with certain Socionic IM elements usually become widely popular (vs. people with other elements.)

YouTube creators like Fred, The Annoying Orange, Shane Dawson, and Niga Higa -- those with largest followings on YouTube -- all share characteristics in common that I think might be Socionic quadra related.

With that in mind, to which quadra do you think that these YouTube creators belong..?
