For your consideration, I give you V of the comic series and film. He's obviously a thinker, given his belief in the power of ideas. Circumstances have driven him to be I rather than E.
So I would type him as IxTx, so far.
He's literate, a student of history and literature, and a collector of fine art. He has a well-developed aesthetic sense, and an appreciation for form and symbolism.
Yet he is no navel-gazer, but a man of action with very little risk-aversion.
What's his type?
