Sergei Ganin

[FDG]

Who said you needed to argue it? Sergei Ganin is INTj. DUH! That is like, uh, obvious? He says he is. He has no reason to lie. He understands socionics. He's known about it for more then 15 years. He hasn't done anything to consistently show he is lying. So WTF?

I doubt he is INTj. He is too in-your-face condescending and rude ( gone bad). ESTp? ESTj?

Neither INTj nor INTp. Too unpleasant in an sort of way.

NOW TREAT ME LIKE AN IDIOT! YAY!

I personally think he's ISTj, and that would totally fit your observation.

ENTj is possible.
