I wish I could take the LIE vote back because I can't seem to decide on this one... the more I think about it the more I'm unsure. As nebula said he very well resembles an ExTJ, whether he's a Ni or a Si remains to be seen...
What made me pick LIE, and I'm still in favor of this option because of this, is the portrait over all of the LIE. Schwarzenegger resembles that portrait, pros and cons.
On the other hand if I go by functions and stacks alone I have to admit he looks and behaves more as a creative Si, and all that Se.. UGH. Maybe the question of proof is... does he look Ne? And he doesn't look Ne at all to me... and demonstrative would supposedly show.
