As far as Edgar is concerned, Edgar is so dom Te it's ridiculous.
That fact that he chose INTJ has nothing to do with his dominant function-which is in fact, Te.
Just for the record, everytime I took a myers briggs test, I would score INTJ, and Keirsey's description fits me almost to a tee. However, whenever I would take a functions test I would get Te as a clear dominant.
I figure I give you and simulatedworld more fuel for your arguments.
Seeing you two fight over me gets me wet.
Listen to me, baby, you got to understand, you're old enough to learn the makings of a man.
I don't find it inconceivable for an INTJ to have a strong Te, even stronger than their Ni. Ni is normally described as an unconscious function, while Te is usually written to be much more conscious. Given this distinction and any sort of desire for improvement, it's reasonable to conclude that Edgar, and INTJ, has worked on improving his Te.
*insert note about strongest function not being dominant here*
If a deaf INFP falls in the forest and no one is around to hear it, does it make a sound?
