From the pictures: you can see a lack of confidence in Sensing and in Ethics. Not really sensual or anything like hat. Also, not really that expressive.

"Quite possibly the bluntest person I've ever met in my life." Supports weak Ethics. I think weak .

"Very short attention span". I think this supports an Extraverted Percieving function, so or and because I believe he has weak sensing, .

So as for my type hypothesis, ENTp .

Weak Ethical. So any logical type.

Weak Sensing. So an Intuitive type.

XNTx At least I'm sure of that.

Hypothesis: ENTp.

Not really a lot of information, so I could be grossly wrong.
