I agree with ScarlettLux and Slacker Mom.

Simply because I agree that he's an Ethical Irrational. IEI, IEE, SEI.

I see cases for each. But is there anyone who can give a convincing case to determine which?

From viewing his video. He seems like like he's trying to be comfortable with the interview, yet does not know where he is going. And needs a direction. That's just the feeling I'm getting. And also, he enjoys being himself, and doesn't dramatize things. Again, all these in my POV.

I agree with Joy. LIE? I can't see that.
I don't think he's a rational. So I don't think EIE, or an Fe dominant. But then again that's just me. Anyone gonna evaluate this?
