I've been thinking for a while, and after seeing the Deltas search for the ESTj, an idea popped into my head.
We have tons of INTjs here, as well as some ENTps, INTps, INFps, ENFps, ENTjs, INFjs, and the such. But where are all the ESTjs, ISFjs, ESFps, etc?
Well, it's obvious that most of the people here are pretty theoretical. But what attracts you to Socionics in the first place? A lot of the types that are in abundance here don't seem to fit very well into society. Now, think of the types that aren't readily seen around here: ISFj, ESTj, ESFp, ESFj, ISTj, and excluding me, ESTp. People of these types seem to fit very well into what society considers "normal." My conclusion: the Socionics theory seems attractive to those that have felt like "the oddball" in life.
What am I trying to get at here? With all this craze recently in forming complete quadras, it's pretty unlikely that we'll get people of all types to post here. Not just because they don't care about abstract things, but because they have very little need to use the theory in order to relate to people and fit in somehow.
The reason why i didn't put this into Cone's crazy ass theory thread was because this isn;t so crazy ass at all. This is what my 14 year old mind could come up with.
