I was watching Back to the Future recently and started thinking that Emmet Brown and Marty McFly might be a fictional representation of a LIE-SEI dual pair. I originally thought of McFly as being ISTp, but he seems to actually give off a pronounced feeling vibe in a lot of situations. So I guess the question is, would literally heading off into the great unknown just for the hell of it with their LIE dual something a SEI would be inclined to do? Are they explorer types? I guess McFly might be better typed as an ESFp, not sure.
